The 14A and 15A have a lot of parts in common. With the exceptions mostly being between the engine and the rearend (clutch, TC, transmission).
You can use 'some' final drive parts from older D-8's (1H, 8R, 2U, 13A) in your 15A final drive. The bullgear, hub, sprocket and covers will interchange.
Had a 15A many years ago but sorry, all the books went with her when I sold it.
The 14 & 15A both came out in 1955 and as Old 3T Lover said they are pretty much the same except from the engine to the steering clutches as the 14A is an oil clutch with regular trans. & the 15A has a torque convertor with a dry clutch and a different transmission.
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.
