OM60_series IP delivery valve reseal
 

Here is the official MB procedure & torque figure for the reseal process.

Thanks MB DOC:).

And here it is right side up.

anyone have a part number for the 606 seals? Our parts dept can't get them supposedly. aren't the 603 seals the same part???

This is what Phil came up with for my 99 E300 (OM606.962)

0179974148 Injector Seal $.40ea

0049974540 Delivery Valve Washer $.90ea

OF course with acrobat reader you can rotate any document. Sorry bout that.

reset pump timing
 

Is it necessary to reset pump timing after replacing o-rings and seals? I am hoping for a r&r job. (I know. Hope is not a strategy)

nope!

thanks John
 

Good deal. Thanks again.

O-ring sizes.
 

If you find yourself in need of the O-rings, and there is no MB dealer handy, or you need them "right now", they are 19mm on the OD and 15mm in the ID.

It's correct that the o-rings and copper washers are the same as those for the OM603 such as the 87 300D. I don't know why these parts are not being carried for the OM606.

I didn't know that one is supposed to replace the compression springs when doing this job. I don't even see these in the catalog. I also don't know why but after each time I did this job I got more nailing at idle, but it should subside eventually. It took my '96 about a month after this job to get rid of the idle knock when warm; there's still some when the engine is cold but it was there before the job too. Also I don't see any need for taking out the pressure valve and carrier while doing this job, only what's above these parts.

springs
 

Anyone out there with a clue as to spring p/n or supplier? Good thread. Thanks. You guys are diesel gods.

Get the number off of the side of the injection pump and take it to an authorized Bosch distributor and they can sell you the spring (along with anything else needed for the pump). I have found the local MB dealer kind of useless when it comes to parts for the Bosch fuel injection pump.

The MB PN for the delivery valve springs are A 001 074 21 93 and they list for $6 each from MB. I don't think they routinely need replacing though unless you lose one or find one broken regardless of what the WIS says.

Great Post
We need more of these.
