Being externally adjustable, What is the difference between adding a shim washer or turning in the adj. screw 1/8 turn

Is it possible that when the grid heater comes on, the injection pump is also asking for more fuel, thus the pressure drop. Some computer controlled gas rigs do dump more fuel during warm up as a means of electronic choke control. Just a thought, I don't know.

Direct reading industrial oil filled 0-30 guage plumbed to the injection pump inlet fitting.

Last month set pressure went from 19psi to 16psi. I tweaked the adjust screw back to 19psi. Today it is at 22psi idle. 19psi no load. Been readjusting for the last year. up down, up down. Is this normal? Thinking I will just watch it for a while.

I get the same fluctuation with my airdog raptor 100

Looks good. My 1955 dana case spreader fits from 27 to 70 series. I always use it. How else are you going to get carrier bearing preload?

Ratio tag on the differential and a sticker in the glove compartment.

I assumed that the passenger side line is the return to the trans and should not have pressure. I also thought, that coolers purpose was to bring the oil back to engine temp if the air to oil cooler cools it too much in the winter.

If it is the clutch pack binding it will snap violently. I had a sand drag machine that needed diff oil changed every season. Turning one wheel and the other does not turn, the pinion is turning and rig is in neutral.

You were looking for the clunk sound when turning under power. Loose spiders will not make a clunk. I had a business rebuilding dana diffs. How much play is in your pinion if you rotate it back and forth. 1/8th turn would be normal wear of the spiders. 1/4 turn would be excessive. Are you starting a rebuild project for a minor wear problem. You really should have a diff. spreader, depth guage set and special bearing drivers and pullers to do a proper bearing replace job. New limited slip oil and silicon sealer will cure your original problem.

Drop the cover and look for metal. But, it sounds like the oil may be worn out. Could only need oil change. Some 4WD use really works the limited slip clutches and oil.

Yea, tried all that when new. Even put a splitter box behind tranny that gave me a double overdrive with no help on milage. It did give me a gear slit for the Grapevine grade. 42 mph in second over. Made 2 trips across US with my 5r at 19,000 lb combo. The most I ever pulled up the Grapevine was 24,000 gcw. Thanks for this wonderful forum and the come back.

I have owned a 1992 dodge Cummins,auto, 4:10 ratio cab and chassis since new. Did not know about this type forum in those days. My son still owns the truck and uses it in construction. Has 10 ft flat bed. Average milage is 15 mpg hwy empty at 8,000lbs. 10 mpg at 21,000 loaded pulling loaded trailer. ( no weight police please) Just a dog on take off but will produce power on a dyno at full throttle. I had purchased several dodges for a fleet I managed and was happy with their fuel milage. 19-20 mpg with heavy service bodys and variable traffic conditions. Dodge and cummins worked on it when new and adjusted the timing. It just acted like it may be a tooth off on the cam gear. Many years and 350k, later just resigned to it. Any ideas???

That old 165 with an automatic was such a dog compared to my previous 460 ford gas guzzler. It didn't really feel that bad empty, but the guage said I didn't have power. Really got me between the ears. And I was all stressed about moving my bees back over that big hill. The grapevine is 3 miles long, with 2 solid lanes of big rigs working for position. Very intimidating when under powered and carrying 6 million bees at night. The truck was still under warranty and they did not charge me. The worst part is to admit that I was running a 20 man heavy equipment repair shop. I should have known better.

Looks like a tough job to me. I would watch it until I get at least some drips. Have you extended your blow by tube? Oily residue could come from there.

Is the pump on the 5.9 in 1993 the same as 2001? My sons 93 has leaked forever and my 2001 just started to leak.

A 3 gallon pressure accumulator tank between the filter and the vp44 would also increase available voluum but where do you draw the line. 3/8 banjos , with drilled out banjo bolts and 3/8 line from the tank forward is a 250% increase in voluum over stock.

my 92 all of a sudden had low egt. Truck was still under warranty. I had loads of honey bee colonies on the other side of the Grapevine , 3 miles of 6% grade. I just knew it would not pull that grade with 15,000# load. I loaded 4,000 lbs on the bed and took it to a dodge dealer. They worked on it for a month then I got permission to take it to a shop called diesel dyno tune. It was putting 175 hp to the ground with 19lb of boost. Pyro at 550. Problem! pyro broke. Never used one since.

Go to (Lift pump) in this section. See my posts #11 and #13. See, Vulcanperformance.com for a tele # Drill out all banjo bolts to .182 and use 3/8 banjo fittings . 290% improvement over stock.

Again if you look at my post# 13, The bore size of a Parker Hannifin #8 X metric AN fitting or the banjo bolt is.2962. Drilling the 4 ports of the banjo bolt out to.182 and use the aftermarket 3/8 banjo fitting. Your smallest restriction is .2962 and this size can not be made larger without weakening the fitting.

Did you use 3/8 line from the stock tank suction line to the lift pump? That is what I did and it was a nice snug fit. Did you use a larger ID fiting going into the stock filter?

Dang another mod. I remember when I was dumb and didn't even have a guage.

I can see where a shorted lift pump may kill an ECM, but can not see how a bad ECM cold take out a pump motor. Will a dead short in a pump kill an ECM or is someone selling more parts?

The smallest restriction on your stock set up is the bore in the 5/16 banjo fitting.(.173) The 3/8 banjo bore is .2962, (same as the banjo bolt bore). The 3/8 banjo is a 290% improvement in flow area over stock. Your 5/16 (.3125) line just forward of the tank is Still larger than the bore going into the VP44 (.2962). The 3/8 banjo fittings from Vulcan are 5.99 ea. Suction filter is 7.99. Drill out your banjo bolt ports to .182. Run all new 3/8(.375) rubber line to vp. This is my recommendation for a low budget big line kit for a stocker with no hassel of dropping the tank for a bigger draw stray.

Ivco truck had a cable operated 3 inch exhaust brake back in 92. $ 200.00 new. I mounted it in my 92 350 and operated it with a pto cable. Had less than $350.00 in it including back pressure guage. Still working 350K later.
