Stock# HY288
Price: $ 42.88 I looked again and found this one without drive gear washer, key and jam nut. Maybe that will do the job. Thanks

If you buy the o-rings and gaskets separately, it's about 1/2 that.

This is the kit for the pump…

I would take Bob’s advice and replace only the pump shaft o-ring. Look for the o-ring at an auto parts store, not in the plumbing department of a big box store. You want a #112, buna-n o-ring.

Here are the other parts, if you want to go further…

Well, I went out today and took off the hydrauic pump off the Cub. Not too bad of job. HOWEVER, after I got the pump partially diassembled I found a small spring in a passage way of the pump. My guess from the size it is the check valve spring (350 668 R1) from up in the hydraulic block. I assume that might account for the leak of the hydraulic fluid into the oil pan---in part anyway.. I also assume I now need to take the block off and who knows what else I might find wrong in there----but the hydraulics did work with enuogh fluid in the system,....it just drained out quickly. Welcome thoughts.
