1959 871 transmission pressure test and band adjustment

[KCTractors]

Hi KC sorry for the slow reply. I made that gasket by hand. Was about two hours to make it. If I was to make one again. I would put the SOS control valve body on my computer copy machine/scanner. A normal copy machine is a 1to1 copy ratio. Then use double sided tape to hole punch and use nail clippers to make gasket. I used my Roper Whitney No.5 hand punch with 9/32 hole punch die installed and squared up the circular hole punches with finger nail clippers, 9/32 was nice size hole comparable to the holes that original gasket was.

Once copied/scanned you could save the image/file, and in programs like Inscape make it into a DXF file. Here is a link that better explains the process. https://www.xometry.com/resources/sheet/dxf-laser-cutting/ Then any good vinyl graphic shop should be able to cut that gasket for you. I would do that work and make the file for everyone to have, but my only access to a control vale is installed in my tractor at the moment.

The gasket I used was USA made .020" Thickness Interface Solutions CMP-4000 gasket material. Very nice stuff. but not cheep 4''x20'' about $17. (eBay best deal I could find) compared to junk stuff made in far away lands. I hope this helps. My friend was telling me that he had Fel-Pro custom make him a gasket some time ago. Might be able to get them to make you a bunch.. The first one is the expensive one Hope this helps.

Thank you Wibblewobble for the information. I will have to do the same thing but it will be awhile before I get to it.
