The 5-sided "special washer" on the side of the injection pump. What does it do?

Are you taking about the one next to the the timing cover.........?
The one that you remove the washer and re- tighten to lock the pump?

Yeah, that thing.

It's only a spacer. When you want to lock the pump from turning, like when you pull it, you pull that out and tighten the bolt. When you put the pump back in, you loosen the bolt, and insert the spacer, then snug the bolt.
If the bolt isn't tight when you pull the pump, it will turn off #1. Which is ok if it's going to get rebuilt 'cause they will lock it. If you are just removing and installing for another reason, this will suck! :shock:

I hadn't even thought about that :shock:

it hasn't happen to me because i lock the pump every time i take one out, even if its being pulled out to be sent to be rebuilt.

You could put a perfectly good pump in, with out smashing the key, and have a no start.
no air in fuel, injector spraying solid fuel,,,,,every thing seeming to be right........but fuel spraying on the wrong stroke(no compression)
Sorry folks, I now this is obvious........just hadn't crossed my brain wave until now! :scratch:

So it is only a funny shape so that you can install it without totally removing the bolt that it goes around? Because otherwise a standard washer would serve the exact same purpose?

Yes, you don't have to remove the bolt, letting fuel out or air in. It also locks in place on those tabs so you don't lose it.

The thing is................locking the pump is.....ahhhhh.

Allow me to say, the pump only goes on ONE WAY. It be keyed. The injection pump shop may lock it at the #1 TDC which is key way at bottom. :shock:

THAT SUCKS!!!!

LOL ROF

That funny little blot just plugs the hole.

Scott, that may be. But I screwed up one day and loosened the bolt and the pump turned. :evil:

I had a bitchkitty of a time trying to get it back to #1 to install. :mad:

You replace the pump when things are lined up somewhere other than #1 TDC? That's how I did mine... Or at least, that's how I thought I did mine until I figured out my timing pin was broke off...

Is it eaisier with the keyway at the top?

by **flashgordon** » Thu Dec 20, 2007 10:21 am

Thats how i found my oil leak!......only i was going to see how much a bump, of the timing was worth, with the real timing tool....................

went to find TDC with the timing pin...........no timing pin just a hole. :lol:

Ooooh... Can that leak oil?

I might have found my oil leak too... Could that also explain what the metallic-bolts-on-pavement sound was when I went to merge onto the freeway a week or so ago? Would a broken pin just fall out of the hole after a while?

The pin is only plastic. The tip usually breaks off. It's held in with a star washer jammed in the outer piece. If the washer has been disturbed, it falls out easy, then the pin.

yup, also had this funny bell ringing noise that i couldn't find and the original owner said that it had been making that noise for a vary long time and couldn't get any one to fix it!

The sound is the inj pump gear bouncing back and forth off of the cam gear.

This is now bull. i had the cover off, with the eng running. when i would let my rubber mallet rub on the face of the gear............the noise when't a way.
got spec's on the play of the gear tooth,.......It was in spec.

Found the problem 6 mounts later when i bought one of those expensive timing pins and installed it.
Noise is gone and leak is gone

If you want to here the noise that i talk of, remove you oil fill cap and start-r-up........you will hear it!
