So I gotta 2 piece pump that I was going to use to for my crawler. Unfortunately I have a 3 piece pump and the fittings are completely different. I removed the 3 piece pump and found the input shaft seal blown out and the bearing rollers falling out when I pulled the seal out.
So all I gotta do is replace the seal and bearing right? I went to my local napa where I got the last seal(napa number NOS 8749). Now napa can't figgure out where to get me another seal even though I gave them Their own part number.... :[
Then I tried to get the bearing.. "that number doesn't cross to anything we can see" ..
Its been 3 weeks now. I guess I can't rely on the kids @ the parts stores any more. Time to get the stuff off the internet.
Anyone need a 2 piece pump? I put a new seal in and some speedy sleeves on the gouged input shaft.

NAPA has an online system that you can look parts up, if the parts guys at the store are clueless.
(1) JD Straight 450 crawler dozer with manual outside blade; (2) JD 2010 diesel crawler loaders; (1) JD 2010 diesel dozer with hydraulic 6-way blade; (2) Model 50 backhoe attachments, misc. other construction equipment
I stock the bearings, but not the seal.
