  1. Electric Vacuum Pump Conversion: I have deleted my OEM vacuum and power steering pump(s). Instead, I have modified it by replacing it with a midrange setup for steering assist; however, I still need vacuum in order to activate the HVAC controls and to activate my exhaust brake. Although the OEM factory pump never gave me any issues and supplied all the vacuum I needed to work, such as the HVAC and the exhaust brake, the OEM Power Steering did. I have replaced the OEM Power Steering Pump multiple times. In all cases, the pump would not maintain enough pressure and turning the wheels at a stop during idle was almost impossible. Compound that with the inevitable oil leak between both pumps, I figured there was a better system. So, this is where the "midrange" setup comes into play. The 24V ISB was used in multiple applications (not just Dodge). Even though they were not used in another pickup, they were used in midrange sized trucks like Freightliner FL60 &FL80, Ford 650 & 750, Kenworth 370, motor homes, bread trucks, etc, etc. It was the engine of its era. Trucks with vacuum controlled cruise should work also. This particular modification applies to my setup only; (the midrange setup for steering assist). My cruise is ECM controlled. I have the non CAD front axle, so my vacuum demand is limited. On SD applications, they use it to lock the front hubs and HVAC on their trucks. So I feel it should work on any of our vehicles. I used the same pump from the SuperDuty and 3rd Gen RAMS (same pump). I picked it up from Rock Auto along with a Mating Connector. I drilled 3 holes and mounted it on the fuse box cover, in an easy to service spot. For plumbing, it goes to a control manifold for the EB, and tees off into the OEM vacuum line on the firewall. I do not use a reservoir like FORD uses, but you could run one if you desire it. For power, it gets fused voltage from the PDC power stud, which is also the relay supply power (pin 30). The relay trigger is controlled by a fuse tap in one of the PDC fuses, that is hot only when the key is on, so it does not run all the time. The pump has an internal governor, so when it reaches its vacuum threshhold, it shuts off. If it is always running, you most likely have a leak that you need to repair first.
  2. He removed both units and installed a gear driven power steering pump directly onto the accessory drive gearbox. He also installed a remote power steering pump reservoir. Here is a link to his original post regarding the conversion. You will need to scroll through the whole post as he talks of other conversions, as well. I made the same conversion myself - very happy with the results. It's nice having an accessible see-through reservoir. The direct mount power steering pump definitely out performs any of my previous pumps, including the OEM pump. John

    I bought my parts from a combination of allstate gear and torque king I believe. I had to replace the input shaft, main shaft and counter shaft. Mine was pretty trashed. I also replaced the tail housing, OEM was an aluminum peice, I replaced it with a cast iron piece from torque king.
  4. On September 6, 2016, I wrote the article "Adding inline power steering filter with system flush" and posted it in 24 valve 2ed generation/Axles, Suspension & Brakes. This is the follow up to that article. Update...7/25/2025 It has been 8years 9months and 44,888 miles since I installed the Magnefine filter and flushed the power steering system, so it was time to flush the power steering fluid and replace the filter again. I used an oil syringe fluid evacuator pump this time to remove and refill the fluid at the power steering pump. The picture below shows the first time the fluid was removed from the system It took 5 remove, refill, and run engine for 4secounds to get the fluid to this clear color, about 2qts. Here is the filter cut open. It looks like the filter could last 60,000+ miles before changing. There was just a fine film on the magnet.
  5. It's worth remembering that when racing a Cummins, most will ditch the heater core circuit altogether.
  6. I wasn't sure if it needed to be circulating at all times so I put a 3 way valve on mine to "bypass" the heater core didn't want to take a chance after I broke the last head stud.
  7. I just got home. Ill see what I can do for a measurement for you.
  8. Thats a good point. I just rebuilt my power steering pump and was shocked how much was on the magnet especially since the only worn part i found was the aluminum sleeve the whole pump shaft rides on my only thought was it must be from the gear box. Im about to find and read your original article and add a filter to mine along with a cooler.
  9. That’s my bro-in-laws 2002 next to mine. I put some Bilstien 4600 shocks in it after he helped me with my bumper. That truck was the reason I got mine. I had seen multiple trucks online with the 4th gen bumper. I liked how they looked. Having this one given to me I figured I’d try it. My original bumper was a little tweaked back when I bought it. I had to put self tappers in the plastics to hold them on.
  10. I have done the same. Can't remember the details, but I think you have to slide the seat bottom to certain positions to access four bolts (or nuts), but it is an easy task. John
  11. If you only need to remove the padding, I know the bottom part can be removed with the seat in the truck. I’ve done it twice, once to replace the foam and again to install a seat heater.
  12. I would 100% fix that before i continued. Mine was not cracked and was still pretty tight but i could force it to move. The others i couldnt. Would be a cheap and quick way to rule something out.
  13. You can just swap out another like fuse and another relay and go for a quick test drive. John
  14. There is a single connector with two black wires that are connected to the positive post of the driver side battery. These wires supply power to the intake manifold heaters (grid heaters). Within a few inches of the battery connection, you will see two fusible links - no fuses. Disconnect the the single wire connection. There are two fuse group locations. One is called the Power Distribution Panel (PDC), and the other is called the Junction Block. The PDC is located right beside the driver side battery. Th Junction Block is located on the left end of the dash. The driver's door must remain open for access. Hope this helps. John
  15. You confirmed the 2-cycle oil theory is solid if you have an OEM pump still going. I'm at a +150 HP injector (7 x 0.010, popped at 320 bar (4,641 PSI). Then Quadzilla custom tune which I'm re doing for this coming winter on the day I use my truck. Trick on my end, DO NOT just ramp up power. I don't reach above 100% stock till 20 PSI of boost. So technically, I'm just running my +150 HP injectors and no additional fuel, less stress on the pump for a daily driver. Running about 23 to 25 degrees of timing at 2,000 RPM. Partially to make up for the lateness of the injectors which are popped higher. Just figured I'd share my ideas with yours...

  17. The bolt has worn thin so the sleeve isn't tight around the bolt I fitted new shocks they started knocking a few weeks later. This was a few years ago now truck has been pretty much out of service until this summer. I will update the post with some pictures of the bolts. Shocks I fitted was from rock auto as they ship fast to the UK and they would have been from the daily driver or performance section on there. @Tractorman ignore that just looked the bushes look fine the knock is where the sleeve has play due to the worn bolts. 🤦🏻 It's been a while since I've gone through this truck. Since using it this summer it's had: New sills both sides 'rockers' in the us Rear diff re-bearing Service Ac leak sorted List goes on These do not like sitting around for extended periods!
  18. Here is a trick for next time I found the bolt part number and also the bolt size... BOLT, Hex Flange Head, M14x2.00x80.00, Shock Mounting, Then go back to Google to look up the part... Then select a supplier for the part. I see Amazon and a few others...

    I would suggest a Cummins crank sensor they are not that expensive. We have loads of issues with non genuine CPS sensors over here in the UK. Also as mentioned bump the starter and your lift pump should prime for 20 seconds or so
  20. I'm still experimenting with makeup artistry. Been more focused on the dirt work in the yard, but there are a few days I was messing around. @Tweety Bird wanted to see a few new colors of hair for me. How about fire red? Then I've even been to a funeral for one of my friends, I was dressed in full black and black makeup. The fire red hair, I really enjoy wearing when you get comments about being seen all the way across the store, like Walmart. I love to dress up and interact with the public. The black was a way for me to dress up for a funeral for my friend Dan Catherman. Just after the landslide, he was down helping me hike up the mountain to look at the landslide from top down. Rest in Peace, my friend.
  21. Basically, the pump section pulls out of the reservoir, and there is a large o-ring. As for the pump vanes, I've never opened up. Rest is just o-rings. Be sure you can get the o-rings first before opening. I would check with Blue Top Steering for pump and steering box supplies. https://bluetopsteeringgears-com.3dcartstores.com/

    How are you checking voltage for the lift pump? Where are your test leads connected? Ignition key on - lift pump runs for 1/4 second Bump start, leave ignition key on - lift pump runs for approximately 20 seconds The ignition key must be turned off between bump start tests. John

  24. HE351ve Holset VGT Controller This article is for the standalone controller / tuner needed to control a Holset HE351 ve He351 VGT turbo from a 6.7 Cummins. This controller will help you tune the holset he351ve vgt turbo for your truck. It is is %100 open source you can tune the turbo in any manner you like. It will take some trial and error to tune the holet he351vgt, but the pay off is worth it. The he351ve really shines when it comes to low end power and having a flat torque curve. He351ve Airflow Specs The reason for wanting this turbo comparted to another aftermarket turbo are, Increased flow over a hx35 turbo ( 60lb/min to 69 lb/min) built in Exhaust Brake functions, Cheap turbo cost, fast spooling, and good mpg's if you have it tuned right. For a 5.9 Cummins the he351ve makes a great towing turbo for hp levels up to 500. It will be hot at 500hp but it is possible, not recommended, but possible. This should also work for He451 ve vgt or other Holset variable Geometery turbos. 551 431 turbos There is a certain amount of DIY needed to get this setup on your truck. You will need to learn the arduino system, how to wire it, power it, etc etc etc. Basic Video Here is a Video of the basic code and how it works with the VGT turbo If you read through this and have ANY questions, feel free to Post to the Ongoing thread covering the progress on this project You can Find the Forum Link HERE Parts: Here are the list of parts that are used. you can void the code to use one or all of the sensors, but this list is for everything.

Turbo Connector 4 pin: Mouser Connector Link 54200410-B Pins 10762770 Turbo RPM Connector: Mouser Connector Link PN: 282087-1 Software: You will need to download the Arduino program: Arduino - Software You will need the libraries that I use. You can Download them all from My Google Drive Download the Canbus library: Dropbox - CANLibrarymaster.zip (thanks to Farm828) download the LCD Library: Dropbox - LiquidCrystal.zip Download the Freqmeasure library https://www.dropbox.com/s/yv98sgdllckc9z4/FreqMeasure.zip?dl=0 Download the Timer library https://www.dropbox.com/s/xa0lxny0pftdi6h/Timer-master.zip?dl=0 Basic starter Code downloaded here: Dropbox - HE351VE_Control.ino (thanks to Farm828) This is the code from CF without my changes You can edit the code by voiding the sensors "//" you are using in the right section, defined. My code has changed significantly from the above. How to Connect everything I will go into some detail here. First basics of the arduino uno and cabus_ shield. Arduino boards allow you to "stack" shields onto it via the pins on the outside edge of the board. Each Pin on the arduino and shield correlate to the Pins the code below. You can think of the Arduino as a Small computer and the Shield as a device to perform another specific task, like WIFI or Audio or in this Case Communicate on a Canbus Network. Stacking the shield onto the Arduino allows the arduino to talk in Canbus. First is the Arduino Uno Next is the Can bus Shield that you stack on top Together they should look like this. notice how they are connected, stacked on top of each other with the pins from the shield extending into the Arduino board. Each Shield will use some pins so your code must take that into consideration. Just as an example the can bus shield might use pin 10 and 11 ( I dont remember off the top of my head) so in your code you can't address those pins outside of the canbus shield use. Next you will need to connect all the wires to the sensors. I used some weather proof plugs to make my arduino detachable from the rest of the wiring harness. You will need to figure out a way to connect your harness to the arduino. I used a shield to do this like this. Now for actually connecting the wires from the sensor to the board you will need 3 wires for boost -5v -Sensor return ( pin A0) -Ground 3 wires for Drive -5v -Sensor return ( pinA1) -Ground 3 wires for Pot -5v -Sensor return ( pin A2) -Ground 1 wire for TPS -Sensor return ( pin A3) 2 wires for PotSwitch -Ground return ( pin D2) -Ground 2 wires for EBSwitch -Ground return ( pin D9) -Ground 4 wires for LCD screen -5v -Ground -SCL ( Pin A5) -SDA ( Pin A4) 2 wires for The turbo Shaft speed input -positive signal ( goes to the 9924 chip) -Neg signal ( goes to the 9924 Chip) -Output from pin 7 of 9924 chip to pin 8 of the arduino. Here is an example from www.Arduino.cc of how to wire a simple pot/sensor. you can see 5v. ground, and the sense return going to pin 2 Keep in mind some shields provide more 5v outputs and grounds than others. You can splice the grounds together and run them into one or a couple grounds on the arduino. The Code He351ve Boost/Drive Controlled My basic code is as follows for controlling the he351ve using boost and drive.. You can change it / use it / do whatever you like. You can download the tab'd version of the boost controlled code HERE Keep in mind that it is VERY easy to overspeed the he351ve turbo. Holset rates the turbo to 130,000 rpm. Using the code below I was seeing speeds of up to 160,000 rpm. ENSURE you tune the turbo for your fueling. I found that it is nearly impossible to manage the turbo efficently without using shaft speed so I do not recommend driving the turbo on this code. You will run into egt issues, you will run into shaft speed issues. the boost map code is no longer updated so the version that is hosted is what you get. I have noted in the code as much as I could,. The basic run down for what this code allows is. - During normal driving it will allow you to choose from 3 different boost maps, performance, daily, and Economy by using the pot, with the switch off, to have low/mid/high input from the pot. Vein position is managed by the boostmap until 30 psi is hit. after 30 psi boost the program will switch over to DPmanage and it will attempt to keep drive pressure at 50psi ( defined by code "maxexhaustpressure") which keeps drive to boost ratio within check, 40psi boost theory max 50 theory max drive 40psi/50psi gives a ratio 1.25:1. the HE351 turbo seems to like a high ratio on the lower end. I see ratio of 2:1 all the time until boost is above 20psi, then it starts to level off and come down closer to 1:1. - Turning the pot switch on allows you to manually set the vein position as long as throttle input is below %25. If you turn the pot all the way to 1000 value ( turbo is limited to positions 40-970) it will lock the turbo %100 open regardless of throttle input. You can use the pot to set the turbo position to small and allow for fast warmup. - Exhaust brake will work provided pot switch is off and throttle input is below %5 it will try and keep EB pressure at 45psi per the code. If pressure increases to above 45 psi it will slowly open the veins. He351ve TURBO RPM based Controller Code Thanks to hakcenter at lilbb.com I have edited my code to include his turbo shaft speed controller for the turbo. It is smoother and more refined than using the boost/drive to control the vanes. You will not run into EGT issues or shaft speed issues using this code. You can download the code in the attached zip ** versions after 1.11 are for the arduino mega so if you are using an arduino uno ensure you use version 1.11 This requries you add a 9924 chip to your controller to count rpms. I highly suggest you visit www.lilbb.com and look at his controller shield for the arduino if you want a more out of the box controller. Additional Parts Umax 9924 Chip: Mouser link Pullup Resistors 10k: SparkFun Link You can find the documentation for the 9924 HERE, Click "Data Sheet" Chip: Pins: Basics on wiring for A2 Mode: 1 vr+ ( turbo +) 2 vr- ( turbo -) 3 NC ( not connected) 4 GND 5 GND 10 +5v 9 GND 8 NC 7 IO8 + 10k + 5v pullup 6 GND Top left is 1, Top right is 10 Bottom left is 5, Bottom right is 6 He351ve Shaft speed Controller with ODB interface In my quest for a better controlled turbo I have decided to interface with a pretty cool OBDII interface. It is $39.99 shipped and should plug and play into your arduino. It converts the Canbus info into serial signal that can be read by the arduino via the library that was created for the device. You can find it Arduino OBD2 reader You will plug this into your vcc, gnd, tx, and rx pins of the arduino. Due to the age of the cummins there is a limited amount of info that can be used, but it does read RPM, TPS, Coolant, and IAT ( I think) maybe some other stuff, but I am not sure. The biggest perk to this is you can now use Engine RPM in your code to increase the vane size at higher RPMS while keeping the turbo responsive down low. You can download the code in the attached zip This code is still Beta so use at your own risk. Spool speed with the He351vgt. I went to about %35 throttle at about 8-9 seconds into the video.
