I hope you used a grade 5 or better bolt. It is probably just as good as the original.

Hi,
J P Tractor Salvage at the bottom of the page might have the part for the Touch Control.
I don't know if they sell parts of the units, or not. :)

Checked out JP Salvage yesterday online and didn't think they would sell a single pin. Should call them and see what they say. I didn't use a high grade bolt. Thought being, that part of the pin just needs to carry the load of touch control lever movement of the control valve. just a small fraction of the full 1500 lbs ? of hydraulic pressure that could be placed on the larger diameter of the pin. If I notice even a slight bending of the bolt as time passes I'll know I was wrong.

FYI...you MIGHT be able to reuse that very expensive lock washer if it is in good condition, and the small locking tab is intact. You can bend up the washer on a different flat of the nut, if it hasn't already been done.

Or you could substitute a 3/8” inside toothed star washer.

Afraid I bit the bullet and bought the expensive washer. Did not think about an inside toothed washer. Did pause a bit before I added the washer to the cart. Paid less for the last Timex watch I bought myself, and for me it's a really nice watch.

Received pump rebuild kit in the mail today. I've worked on many things over the years but I've never rebuilt an oil pump. Thanks to Dale Finch for suppling me with the attachment to troopfpc's HOW TO posting on tear down, cautions, reassembly of oil pump. troopfpc if your still out there, Thank You for your posting. The odds of doing the job right the first time increases greatly with your descriptions and pictures.

Touch control oil pump has been rebuilt, installed, and all is working well. Time will tell if any fluid continues to flow into the engine. Found the inside of the pump to be very clean, same as the block, someone has already been there. The body seal ring as well as the drive shaft o-ring were like new. But the two o-rings listed as cover bearing seals were brittle and shrunken, one was broken. Guessing for some reason they were the original o-rings. The drive shaft where the o-ring sits looked very good and I polished it up just a little before assembly. If I still have a problem think I'll go the SKF 4909 lip type seal i've read about else where on this site.

Thanks Again everyone.

Tim

Touch control pump was still leaking into the crankcase. Drilled out and installed SKF 4909 lip seal. After about 2 hours of run time the hydraulic block is still full and the crankcase oil is still just at the full mark. First time this has happened since I bought early last fall. I was more hopeful after the installation of the lip seal simply because it makes contact on the pump shaft above where the o-ring has run the past 70 years.

Thanks to all who helped, and those who take care of the site for being able to access info on the site about installing a lip seal.

73 deg. here this afternoon. Mowed with it for about a half hour, will see what oil levels are in the morning.
