driver444 Posted January 29 Share Posted January 29 Is there any obvious way to tell if I have a Pesco or Thompson hydraulic pump on my ‘57 350u? I have to rebuild it because it’s pushing Hy-Tran into my crankcase, but they both look so similar. I know I can pull the pump and get the number, but I’ll have to move the tractor to do the job, so I don’t want to do that until I have the parts. Any help appreciated. I have the following numbers stamped on the outside of the pump, but they don’t coincide with anything that I can find. 3A2807 0510135 P2 Quote Link to comment Share on other sites More sharing options...
