Caterpillar Diesel Part

[whatever]

Just wondering if any of you might have a contact or supplier where we might can purchase a used, pully assembly for a water pump">raw water pump? Have to replace raw water pump and having a heck of a time getting the pully assembly off the old to put back on the rebuilt one. Afraid that it will be bent when and if it comes off! We have Caterpillar 3208's the water pump is a Jabsco rebuilt 6400-1051 and the part number in our 1988 parts catalog indicates the part number we need is 4W1812. Have spent hours on the web this morning searching by part #, no luck and have sent requests to half a dozen places to see if they have. Thought I would try the collected group of knowledge on here for help. Thanks for any help!

A puller & some heat on the hub of the pulley & it should come off. That is a cat part # have you checked with a cat dealer?

Capn tried the puller and then got a propane torch and used that with the puller and only was able to get it to budge a little less than half way. Still jammed on the shaft! And yes we did finally call a Dealer today, was really hoping to find a used one, but doesn't seem like that is going to happen so Monday will have to order a new one, and just use the spare pump we have aboard since we can't get the pulley off. Thanks for your reply!

I've removed gears & pulleys from shafts using a press. May try finding a shop with one & see if they can press it off the shaft. Worst that can happen is mess up the pulley. Good luck

If it moved halfway you should be able to get it off.

Try coating the shaft with light oil and putting some oil in the pulley hub. Let sit for a few minutes. Gently tap the hub back on the shaft. See if that doesn't loosen it up and it should come right off with the puller.

DeepFrz, I think he has already done that, I will mention putting on the shaft as well though and try again.

River Cruiser, Thanks for that suggestion as well, we will give that some thought.

Appreciate the help!
