I just re-installed my drive after having the dealer replace the yolk shaft seal. The dealer said that they have never had to replace a seal on the new style SX-A and I even spoke to the mechanic and he said that as far as he is concerned, it must have been overfilled for that to happen. I change the lube myself and it was not overfilled. I always left the level at about 3/4 inch down from full on the flat portion of the stick. I check the fluid after each use. I told the mechanic that I have put 230 hours on the engine/drive, but he still said that he was surprised.
Anyone have any comments on this or are aware of seal failure on the new style drives? I'm familiar enough with engines, but beyond fluid/prop/bellows/vent seal changes, I'm not that familiar with the working of the outdrive. It would seem to me that the seal on a SX-A could fail with use as any other.
He said there was slight groving in the yoke but not bad. I assume that they would have wanted to repleace the yolk if it was bad enough. I replaced the bellows while I had the drive off since I was getting water in the bilge, but I did not see rust anywhere--I think the coating of drive oil received from the bad seal helped out. On a replacement yolk, is that part of the u-joint assembly and must be purchased as one or can the yolk be replaced separately?
Thoughts?
