i would still use metal to shim the governor..

plastic inside an injection pump kinda scares me.. look at the old DB2 flex ring governors.. plastic.. that was the reason 99% of the 5.7D & 6.2D engines died and were never fixed..

What part in the DB2 is plastic and what kind of force is on it? How did it fail?

I'll take a look at my practice pump and see if I can determine how much force is on the shim and decide if I should use it or go to metal.

I made one already for practice to get the dimensions right.

Right on that looks alright.

Run it. The most force is at or near WOT. Which as you now know, isnt needed with the GOVMOD/

A copper or brass washer wouldn't even make a roller skip if pieces of it were thrown in its way.

if a copper or brass washer degraded, the metal bits coming off the washer, would be SOO TINY, and SOFT that it would not harm the internals of the pump.. but it would be caught by the screen in the OUT bolt..

ive shimmed 2 pumps in the last year, used stainless nuts in one for a shim, and brass nuts in the last one, just for the fact that brass is softer than steel, but not so soft that its like lead or copper..

The shim is always under compression and does not rotate as far as I can tell, so I do not see how the Delrin can wear. Delrin has self lubricating properties and being submerged in fuel, another lubricant,  I don't think there should be any Delrin chips coming off.

The only thing I am concerned with is how soft the Delrin will get at coolant temp.

So I have a governer modded pump installed on the engine im about to put in my car. Its and ecodiesel motor all stock but with said gov modded td pump. I dont plan on driving fast 99% of the time. I dont have an egt gauge, tach or boost gauge. Should I worry about killing my engine? Boost isn't turned up at all either.

No. ;). If your not rolling ungodly amounts of coals and the engine is setup properly (ie. not extremely retarded pump timing) then it will be fine. I wouldn't run around WOT even stock though, they get mighty hot! lol

Is the governor from an 81 NA 1.6 the same as the governor from the 92 Ecodiesel? I want to swap the NA governor in lieu of the modded governor in my Eco to test egt, smoke, performance differences.

Did you gov mod your eco pump? How well does it work?

To the eye, the springs look very similar.

Yes I did, it puts out a lot of smoke and EGT can get a little past 1200 F if I floor it. I am thinking of un-doing the gov mod and see how much power I lose because I don't like all that smoke since it is unburned fuel. That's why I want to know if the NA pump has the same governor since I have a few spare NA pumps to play with so I can leave the modded governor if I decide to put it back in.

One thing that I notice is that coming off idle at a standstill engaging the clutch, there is not much torque and I have to keep the revs up otherwise it may stall. My 1.6 NA caddy does not do this. Not sure if the Eco did that before the gov mod so part of the reason of un-doing the gov mod is to see if it is related.

That is a relation on how you have your external settings set up. I once had my 1.6 NA setup with a fully shimmed governor and I could get in to fifth gear without ever touching the accelerator.

Literally, could idle through every gear and not stall it out. So no the gov mod is not causing this.

Sorry, didn't see your post till now. Yes the Eco pump was gov modded and it it works the way it suppose to, I suppose. More pedal, more fuel, more smoke, more power. I had it on a dyno a few months ago and I don't remember the exact numbers but I do remember beating out a 2001 TDI in 1/4 mile simulated time.

Well folks I starting this project this evening after checking my timing. The little circlip kicked my can for an hour, then I ended up bent the gov shaft! I have a parts pump so that's fine, and I can grab some tiny washers tomorrow. Is there a chance my advance cable doesn't have a spring? I'm doing this in the car BTW, I popped the top off couldn't find it anywhere. I guess I'll drain the pump tomorrow see if I can find the little fella.

Is this on your 81? No the advance cable does not have a throttle bump. Just an internal advance mechanism.

What kind of problems did you have with the cir-clip? On the previous page I show a tool I made for working on the governor. 3 sheet rock screws, a large flat washer and you can use a piece of wood for the base. Much safer than having parts flying all over the place. ;D
