The rod spring 37202 is the return spring and should have pressure on the housing when the clutch is engaged. The sleeve spring is an anti rattle spring the holds the release bearing on the yoke. The important thing is to have the 3 112 211 screws all set to the correct length.

The OC 46 loader would be the best machine because of the lower first gear and weight. There were 3 engines used in the OC 46, a 4 cyl gas and 3 cyl gas and diesel. All are rated the same horse power wise. But the 3 cyl engines are much heavier duty. The diesels are the best as all are dry sleeved and the sleeves are very hard and last a long time. There are 3 version of the 3 cyl gas and diesel engines. The crankshaft was changed twice so there are 3 diesel blocks and cranks. The first two version of the gas engine are not sleeved so there are two gas blocks. The last gas version used the same sleeved block as the diesel, so is the best of the gas engines. So since the newest of the OC 46 loaders are 55 years old it is not easy to find one with an engine that is not wore out. Parts are available for them but the diesel pistons are hard to find. If you are looking to buy a 3 cyl machine post the engine serial number and I can tell you what it is. I have a loader with a new 4 cylinder engine and a 3 cyl diesel that is rebuilt and both work well.

The FD started life in 1936 with a Hercules DHX engine. In 1938 the tractor was upgraded and the engine size increase to a DHXB engine. In 1941 due to a shortage of Hercules engines the FDLC with a Cummins was made. In 1945 it became the FDE with a Hercules DFXE engine. IT was made until 1952 and then the OC 18 came out.
