Interesting, didn't realize they were tapered - is the fix just to replace the parts or can you machine a sleeve for the bottom piece? Also, does it have to be tapered - maybe straight splines are a cheaper option, would be a tighter fit than now. With used machinery going for top dollar right now due to lack of new equipment, might be worth it. But, hey, what do I know, just commenting from my armchair. Anyway, great job on the fix.

Hi Wes, something to try next time you have worn splines is 24 hour Araldite epoxy. We use it on most splines on our cane harvesters. It takes a good beating during the season and seems to hold up very well. That slop in the splines is taken up and more wear is prevented. The only catch is, it’s difficult to get stuff separated for disassembly. Relatively inexpensive repair and worth a try. Give Molykote 111 a try for your seal and o’ring lube. Great product for resealing hydraulic cylinders.

A thin coat on both sets of splines and assemble, wait required time to harden and away you go. You can never get it apart ever again I tried to look up the stuff we used, its been too many years and I cant remember the proper name. Belladona or something like that. I can't find it anywhere. Great stuff. The millwrights in the pulp mills used it lots, that is where I got the idea from. If you do it right it will last forever but you only get the one chance.

Always wondered how those slew motors worked. I drove a Ford 550 with a similar set up. Slew wasn't that powerful. Digging on a slope it wouldn't slew uphill unless you brought the bucket in near to the back of the machine. I expect these motors were used to avoid the Wainroy patent on the two ram system. JCB had a different "rack and pinion" set-up. The early ones weren't enclosed and used to go bang when a stone went through the workings.
