I am in the process of repairing a cracked timing cover case due to the KDP.

Is it necessary to check the timing after pulling the gear to take the case off? Nothing moved as far i can tell when pulling the gear. I put the gear back on an torqued the nut down to 140lbs while holding the crank in place.

Also, should i replace the lock washer it was flat. I bent it out a little before putting it back on.

I don't want to get the whole thing back together again and the timing be off.

Did you put it at TDC and pin the pump?

If not, you can put it back ( hopefully no one has messed with it ) to stock by pinning the pump and using the pin on the cover.

It was at TDC but I did not pin it. The case came off and so did the pin when replacing the case. The engine did not move in the process.

You might get lucky, if your IP didn't move. I would pull the pin holder and look to see if the slot is visible. If it isn't, I would still put it back together, you can always pin the engine and pump later.

Do you have a FSM?

This may rub some the wrong way, but I think you're almost certainly ok just putting it back together. Hint: Jeff Garmon (of Garmon's diesel performance) held a class on 12v performance a year and a half ago. He mentioned that (while the gear is still off the injection pump shaft) turning the crankshaft "backwards" from normal engine rotation such that the damper travels the width of the flat part of the ESS is 7 degrees of advance. Just saying...

Ok thanks. I did scribe a mark on the IP shaft before the removal and it still appears the be in the same spot.

How to check and reset your timing back to stock

Unless the pump was pinned, there is a good chance the cam rotated a bit when the gear was popped off the shaft. Putting it back together without setting the plunger lift is a bit of a crapshoot. Might be exactly where it was, could be 30 degrees retarded. I've done a number of timing jobs, not once has the shaft stayed in the right spot when popping the gear off the initial time.

I agree. Have done lots of these too. Sometimes it will stay in the right spot, sometimes you can chase it around for an hour or more, trying to get it where you want it.

Thanks for the link. So basically put the motor at TDC and pull the timing plug out and if the arm is centered it is still in the stock position.

patdaly

Yep, assuming the IP and Engine is stock. Changing to a different spec pump, or if the pump has been off and worked over could leave it in a different location.

But if you know everything is stock, then that is the easy way to factory timing.

Ok thanks. My bother is the original owner so I know it's never been messed with.
