[QUOTE="DeesLLfitER dave743, post: 37311, member: 4330"] Ok a little closer, broken bolt u joint to flywheel is out. clean hole The spline off the pump shaft was a little tricky, I put a puller on it loaded it up and some pretty good wacks with the hammer, deep creep a few days apart, still not wanting to let loose, I still did not want to sledge hammer it, so some ox-acetylene torch heat really quick less then a minute, the surrounding oil/dirt was just starting to bubble and smoke a little, then gave a couple of light taps to the side of the spline top and bottom, then that spline flew off about 2.5 feet nearly branded my arm and leg, the pump shaft was barely warm, but the spline sleeve was smok'n hot ! Next came the seal, the suggestion you guys gave me to drill a small hole and long sheet metal screw worked perfectly, then came installing the new seal, I screwed up and got it just a little cocked and ended up sinking it( i was expecting it to bottom on a flange or ridge) ,but no luck, so now its square but way past the snap ring groove and oil leaks from somewhere, Pull that new one out and back to Bobcat tommorow and get another seal and a little more finess this time. meanwhile oil will be seeping past the oil seal which i am using as a temp plug to save me some oil. more latter dave [/QUOTE]
