I found this in a different thread. I would contact Lavoy, proprietor of this site.


Best regards, Bruce

Kits are about done, should have availability next week. Kit is $2000, and includes NOS Deere flywheel, pilot bearing, isolator and hub for converting 350, 350B, and 350C crawlers to late style rubber torsional isolators.
In the past, there was a disparaging comment made about what I was providing in these kits and their origin. SO, let me be clear. The flywheel is NOS OEM John Deere. The pilot bearing may be name brand import or USA, depends on who I get them from at that time. The torsional isolator itself is made by the EXACT SAME COMPANY that made them for John Deere when they last had them available, and is Made in USA. The splined hub is CNC machined off of the ORIGINAL John Deere drawing, don't ask where I got it. :) All machining, splining, and heat treating are done in USA, period. Hubs are treated to 61 Rockwell if anyone cares. The rivets holding the hub in are OEM Deere rivets.
This is a 8 year long ordeal at least, and I really wish I had been able to do them cheaper. But, to control production to the level I have, and all USA and NOS Deere is expensive, and more so in small quantities.
