I will be posting a link for eBay for d2 and d4 pony motor replacement piston rings. The are not cat parts but work. The rings are a chrome composition for compression . They fit standard pistons and there is a plus . 010 set for slightly worn standard bores.
The are compression and oil for both standard and plus . 010. The seller is in the process of setting up a link for the cat part numbers. He worked with me when nobody else would.
The parts are not for the intended application, but work and fit. I will keep you posted.
And no I will not make a dime, just sharing because I hate when i was told to junk it, pony motor.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.
