Pencil Injector

[Mopar1973Man]

 

 

I was the first to find this flaw in this tractor. Its a 1984 Case C580 backhoe. Number 2 injector was misfiring kind of. We pull the pencil injectors out to find number only had 3 holes and missing its 4th holein #2 injector. (Personal Trophy) Owner said its been in his father construction company and now he's using it for his construction. I'm the only one that found this rare one with three holes and not spraying right at all. Even did a quick valve lash at .012 Intake and 0.014 Exhaust.

 

The actual size of the injector is just about the same as a standard #2 penicil.

 

Holes are very tiny. Barely see the one hole here.

 So, a manufacturing defect? Plugged?

Physically missing the hole. Never was machined and missed. 5 guys looked at it and its missing not plugged.

Gotcha, so really it should have never really run correctly from new (or when the injectors was installed)

Wow

So is this 36 years "It's suppose to run like that"  of quality control? 

 

Good call!

Nice job diagnosing that.

That is something.......I would have had to have at least ten guys look at it to be sure,  Good one Mike. He's got a new 1983 Backhoe.

Yup. The engine runs great he started to use it and the rear axle started to bind up. I'm researching how much it would be to change a rear axle, or pull it out for a shop to rebuild. Might tell him to load it up on a trailer and send it to Lewiston, ID.
