water pump pulley mesurement
water pump pulley mesurement
If any of you fine folks have an extra water pump pulley, could I ask for a measurement? With the pulley sitting on a flat surface, what does it measure from the table to the hole in the center where the pump goes through? The one on my Lincoln is a bit messed up and I don't know if the BMW part is the same. The Ford part is of course unavailable.

it might be the same as the m20. I will try to measure when I get home.-Paul. you want outside lip to center of pumpshaft right?
Re: water pump pulley mesurement
yeah, total depth from the back edge of the pulley. Just sit it on a table and let me know the measurement from the table to the hole where the pump sits. That should tell me what I want to know. I'm hoping the BMW part is the same as the Ford. My WP pulley was mangled a bit and its got a distinct wobble to it. I think thats why it keeps eating the V belt. I fixed it somewhat but it looks like someone tried to hold it with a pipe wrench and its not quite round anymore.

So, it might have been mishandled? Who could it be?"I think thats why it keeps eating the V belt. I fixed it somewhat but it looks like someone tried to hold it with a pipe wrench and its not quite round anymore."

weren't me, but I don't know the history of this thing before I owned it. Have a new one coming through one of the BMW vendors. It doesn't ship until middle of April though. Hoping to get another couple weeks out of the belt. I bought an NOS alternator pulley too, plan to change both and the belt in one go. I'm hoping that will fix it. Currently its basically a belt every oil change, which is bullshit.

just as a final follow-up, I can indeed confirm that the BMW 524td water pump pulley is identical to the one used on the Lincoln.
I also found that the wave washer that are supposed to sit under the bolts were missing, which let the bolts work very slightly loose. The fan clutch also wasn't de-clutching so it was driving a lot of load. This ended up turning the 4 mounting holes into keyholes, the bolts were damaged from the vibration where they passed through the damaged pulley, and the whole mess was wobbling and causing the belts to self-destruct. Have a new fan clutch on order from a gas model. The diesel-specific clutch is way too expensive (best price I found was $250 for a Behr, shipped from Latvia) so I spent $80 for a Behr that fits basically everything from the mid 80s through the end of the 90s on a laundry list of models.
cheaper clutches do exist but I've had bad luck from cheap junky clutches on other things, and I do not want to pop a head gasket to save 40 bucks on a fan clutch. I have no temp gauge on this so by the time I know anything is wrong its already too late.
