Westerbeke/Perkins diesel swap into Gehk 4610 skid steer finished and working 

That seems like a hell of a deal, The drive control adjustment seems pretty straightforward as long as there's nothing wrong with the pumps and motors. Mine seems to have all the power you could want and is a real work horse. Good Luck!

I just used the heaviest grease I had. you can get the engine side bolt on flange for about 100 from germanbliss, Gehl part number 074210. My pump side shaft was definitely not perfect, but that is much harder and more expensive to replace. If my pump side shaft spline was ruined I think I would drill through the coupler and shaft and put a grade 8 bolt through it. It won't drill easy, but with some good drill bits and patience I think you could get by that way without replacing the entire pump.

That’s a good idea to drill out if it fails again. I’ll keep that in mind. I had my radiator weighted door break off at the hinge and need to weld back on just worried about the hydraulic fluid tank on the inside of the tank

@@Centralrc1 It's a pretty thick tank, I'd probably just go for it, but it's also pretty easy to syphon out the tank into a few 5 gallons buckets, weld it up and put it back in. Good luck!
