Hi Russell, I think I heard or read something similar but can't find anything about that in the operating manual. Do you know where that might have come from?

With my M4500DT there has always been a slight graunch when engaging live PTO from neutral, even after playing with the PTO clutch engagement, I believe that this is normal. Be interesting to know if anyone has silent engagement. Creep speed selector is just a 2 ratio gear selector with...

@AusM4500dt - if you want the complete genuine workshop manual PM me your email address.

I stripped the kingpin assembly because after approx 5500 hours the seal between the bevel gear case and front wheel case was weeping and I’d noticed iridescence in the oil when draining the RH front wheel case. In the overhaul process I found confusing or incorrect details in the Kubota WSM...

@luebb I hadn't come across axially loadable cylindrical roller bearings until now, interesting proposition. Seems to be a recent design. The information at https://medias.schaeffler.us/en/single-row-cylindrical-roller-bearings-with-cage has a lot of guidance on application. Interestingly...

Thanks for asking, it's a question... I don't think its M7500DT, so if not, what is it?

My WSM alleges that this front wheel assembly is for an M7500DT. Looking at the M7500DT parts diagram, there are major differences, like the parts drawings show a different location of the kingpin circlip (#12), a spacer separating the #3 bevel gear from the bearing above it, and other features.

True example: M4500DT from late 1970's, front axle not vented, no leaks.

The front wheel supports of the M4500DT use 50mm ID DU bushings ( PTFE composite plain bearings, dry bearings). When I dismantled them to service the axle, I found that the bores/mating shafts were lubricated, looked like moly grease or similar dark colour and plenty of it, not running dry...

I've never used a hydraulic multiplier so perhaps MtnViewRanch and wsurff can put me right here: if you need to actuate different cylinders - for example adjusting the tilt and angle on your rear blade while operating - I got the impression that it takes extra actions (switching the multiplier...

Thanks, the manual doesn't cover that aspect at all. I suspect whoever serviced it last time left out the double O rings.

Thanks very much!

Thanks Wolfman, I have now contacted Farmland, wait and see. Do you or anyone else with access to product bulletins know if there was any suggested fix or mod for the spline wear or the axle trunnion pivots? Did Kubota ever revise the spline arrangement on later model tractors as far as you...

The splines on the input shaft are worn almost to stripping point. The local dealer says that the pinion (and crown wheel) are discontinued. They aren't discontinued according to the US parts websites but I can't order from US due to Kubota regional restrictions (and price is eye-watering)...

#46 is impossible to get at without removing the kingpin.
