Pump removal tool question

[Billybob535]

I have a 95 OM606 NA with the mechanical injection pump and a 99 OM606 turbo with the edc pump. I want to removed both pumps and put them on the other motor.

I have read about a lock tool for the pump. Do I need 2 of them (one for each pump)?

Do I need any other specialty tools to swap pumps?

IMO the locking tool isn’t mandatory. The pump will stay where you leave it without the locking tool. It’s very useful for setting timing. To swap pumps like you described, casting aside why, it would make timing go more quickly to have a locking tool. I don’t think you need two.

I have done at least a half dozen pump swaps on 60X engines. I have found that set point will move with out a lock.

I have done the same thing making a similar tool using a wooden dowel and a hacksaw.

Having dealt with removing and reinstalling the IP in my car more times than I want to remember, this is exactly my experience as well. The cheap eBay lock will let it move too, the groove in the end of the tool is not wide or deep enough to securely lock the "tang" on the weight. A few seconds with a file corrects that problem.

Greg,

Thank you for the info on the homemade IP lock tool.

I will go make 2 of those so I can lock both pumps for removal.

Just so I am clear I am supposed to remove the plug from the pump where the tool goes, turn the motor by hand until the ridge visible in the hole is horizontal, then install the tool and tighten the plug to hold the tool in place. That sound right?

How would I know if I have the timing correct (or 180 out)? I have never touched a mercedes diesel before.

Thanks

Bob

That is correct.


The timing is correct if the ridge is centered in the hole. It is only there every other revolution of the engine.

That you for the clear answer. I really appreciate it.
