Muckspreader gearbox

As above is there a drain hole ?

Dont think so when mounted in that position, personally, I would just take off the hydraulic motor, 2 bolts or studs, and it will slide out. Then most of the oil will drain out through the bearing.

Just leave it alone.

Yeah that's what Rickerbys told me to do

Are you suggesting that I don't change the oil as part of a service [emoji23]

You need to change the oil regularly on them as water seeps past the top shaft. Whip the motor off and pour sone diesel into the filler plug to flush it through.

Have you ever looked at the speed of operation? Imagine the gearbox on a pasture topper and it’s revolutions during a working day, you would need to run that floor for 6 years to emulate it, those floor drive gearboxes don’t need the oil changing, they are almost indestructible.

And wash any residue that is clinging to the sides of the gearbox straight into the nose cone support bearings.

Could be argued that the slow speed =very high torque that would break down the oil as quick as high speed parts

I’ve changed at least three of them due to them eating themselves to bits due to bearing failure from water ingress. It’s a good idea to whip them off tye top shaft annually as well, clean the splines up, grease them and re fit as you can never get the shaft out of the box if and when you need to. Last time we did the gypsie wheels on one we had to remove the gearbox with the whole shaft. Last gearbox we did we cut the box off the shaft with the gas axe!!!

It’s water getting in that kills them, it gets past the top output shaft seal.

Going by the sight glass that one has water in the oil, looks milky.

I have had them on hire machines doing 50k ton a year and never touched them till we had to rechain them and then we had to cut them off the shaft and failed to press out the centre so changed the lot for what it cost. This thing is only on its second set, when the oil leaks I fill them with a grease, never known a problem.

Take off the plate on the front of the gearbox at the back of the wheel. Clean the gear box with diesel or Jizer and then refill with clean oil. We change the oil on a Western once a year. The bed gearbox is easier to do than the rotor gearbox.
