59 7U milky gearbox oil and shifting hard.

Yes the milky bit sounds like water best to change hot and flush with diesel could be the boot over the shift lever split or just condensation build up, just use any basic spec 90 wt gear oil,
the difficulty getting gears could be the brake on the back of the clutch needs a bit of adjustment or repair, also check and lube the shifter interlock linkage, is it a dry clutch or oil type ??
Engines I use 15/40 DEO be very careful with the pony oil change it a few times to make sure all the old gunk is out of it as new oil can desolve years of settled sludge which then circulates causing rapid wear , park the tractor down hill on an angle if possible so it drains completely , also drain and refill the fuel pump oil (15/40) and the pony pinion clutch( can use 15/40 or 5/30 if a cold area)

Also make sure the metal drain lines from the transfer pump and injection pump are open and are not bent shut. When you check the oil levels in the pump and clutch n pinion see if they are overfilled, if so fuel is getting into the pump and starting engine oil could be leaking into clutch pinion.

Are you saying the oil lines for the main motors oil pump? Or the pony?
Also if they are over filled..this could cause the difficult shift possibly?

The lines come from the fuel transfer pump and the fuel injection pump to drain the upper housing. The over filling is from the pony crank seal leaking down into the pinion/clutch housing. Oil clutch will have a dipstick close to the inner side of the right brake pedal. The drain for the pinion is under the pinion towards the flywheel housing the level plug is in front on the pinion housing. Drain for the injection pump and governor is under the governor.

The @3/16" metal tubes are below and ahead of the fuel transfer pump. Try to find a service and operators manual on ebay, these will be very helpful down the road to good service and operation. Cat has them also but very pricey.

Great thank you! I do have the manuals. Thanks again!

Grat thank you! I don't know if it is a dry clutch or not, how would I tell? I will look into on how to adjust, I do have some old manuals. Also I will most def lube the linkage and be sure the gear box is clean before changing the oil. As for the pony thanks for the heads up, I'll run some oil through a few times before to be sure all the gunk is out. Are the fuel pump and pony clutch oils easy to drain or do they need to be pumped out?


Thanks again for the great info!

The oil clutch has a extra dip stick and if you take the inspection cover off and its got a few pipes and a gear driven pump its an oil type ,if its a simple looking thing then its a dry type '''
