injection pump lock washer

[btoscano]

There is a special lock washer on the pump near the timing cover held down by a 10 mm bolt. What is this for, what does it do?



I ask because when I was fine tuning the pump timing it moved down a little (probably moved by vice grips on the housing inadvertantly) so I put it back to where it was by loosing in the nut and putting it back... when I wondered what impact it had?

That is the pump lock down washer that locks the pump in place after it has been set on a flow bench. Take the bolt and turn it around and set it back in and you can see how it fits to lock the pump. Moving it or taking it off won't

hurt anything at this point.

What a relief! I didn't think it would but was in my mind as something to verify.

If you take the fork washer off and tighten the bolt, it'll allow the bolt to go into the shaft or into the lock hole. Fork washer must be under the bolt to prevent damage.

Is ths all visible with the pump off the engine? Next time it comes off I'll look. I didn't tighten the bolt without the special washer so I should be good.
