Hello,
My name is Ranckie and I'm new to this forum. I would appreciate help with a question I have about a 5 H.P. Tecumseh snowblower engine on a 2002, 22" Yard Machine snowblower. The engine model # is HSSK50, 67404S, and the engine family is – YTPXS, 1951BF. When I tip the machine up to work on the undercarriage and leave it there for several minutes, I see oil starting to slowly run out onto the impeller shroud like it's coming from under the drive belt cover, (and from the engine I'm sure). I suspect that the only place it could be leaking from is the crankshaft oil seal on the PTO side of the sump, in other words, a bad oil seal in the sump cover. My question is, does that engine have a regular ball bearing to support the crankshaft or does it use a bronze or aluminum bushing in the sump cover. I have looked at parts diagrams several times and it appears that my engine has a ball bearing but I can't be sure. Getting a replacement bearing should be easy enough at any power transmission store if I decide to go that route. Changing a seal should be a relatively easy task if that's all it needs but if that motor uses a bushing as opposed to a bearing and the bushing is worn, changing the seal will do little good since it will just start leaking again in a short amount of time. I can buy a used sump cover on eBay if that is what I need, and hopefully it would have a good bushing, that is unless I can buy just a bushing for mine if that's what's used to support my crankshaft inside the sump cover. The engine runs great right now and starts in minus10 degree weather with one pull of the cord, (I put a new carb on it). I'm doing this as a fun project on a small snowblower I picked up that my wife wants to use to help me just for the excercise when it snows, (she wanted something smaller since I use a Cub Cadet 26" machine for my self). Any help would be very much appreciated. Thanks.
