Help on "resetting" MW pump?
Help on "resetting" MW pump?
I've been lurking here for years but this is my first post. I've got an 83 300d and a real nice 84 300cd awaiting an engine rebuild.
I'm currently working on the 83 300d, I've pulled the IP in the past and never had any problems. But this time I didn't follow my checklist and I made a few errors. Now I don't know where the pump is in its cycyle and I'm struggling to figure out how to "reset" it to the proper position internally in order to reinstall and drip time. I've been digging on google and found the Mercedes tool (601 589 05 21 00) that locks the IP can @ 15° atdc and one of the sights that sells it says it works for the 617. Its not clear to me if it works for both the MW pump and the M pump? If I'm not mistaken it does work for the M pump, but does it work for the MW pump? I've got plug/bolt removed from the side of my pump and everything looks like it should but when turning the pump cam I never see the timing mark/slot that's used to lock the can with the Mercedes tool.
Does anyone know if the Mercedes tool number 601 589 05 21 00 will work with a MW pump off an 83 300d?
Also just to double check; when I'm standing in front on the car looking at the windshield which way should I be turning the crank when adjusting the timing?
I'm sorry I wasn't able to post pictures of the tool I'm talking about, its been years since I've posted on a forum and forgot exactly how to do it.
Thanks in advance for any replies!!
