WD45 Trans\Differential Oil

Scott

I have a 1957(?) WD45. I took out two plugs under the transmission\differential - they are about 12' apart or so. Anyway... Both were dry. This is a tractor that was sitting out for about 15 years or so and not used. Had engine rebuilt and was checking all fluids when I noticed this. What type of oil should go in for these and where to fill at? There is a large (3/4") square plug on the right side above where one of the plugs is.

The hydraulic resevoir has fluid in it and no leaks.

I would appreciate any and all help!

Thanks, Guys!

Use 80W90. There are two pipe plugs back of the fill hole with the bayonet stab for the hydraulic reservoir. Pull both plugs for faster filling. Takes 4 to 5 gallons to fill diff, tranny, wet clutch & PTO. Watch for leaks at PTO and shifter shaft seals. If wet clutch was run dry for any length of time, the plates may have excessive wear or grooves. If just grooved, run it in oil for a while again & they may be OK. Hopefully your rear oil seals and rear bearing assembly are still OK, or you will have some major maintenance repair to do.
WD45's were made into 1957, so you could have a late one. Serial number will tell you for sure.
