engine removal

Hi Folks,
I am new to the forum and have a question on a Toro WheelHorse 244-5. I am working on mt sister's mower, which has a significant oil leak either on the shaft seal and/or the seal between the two halves of the crankcase. I am taking the engine (14 horse) off to get to the heart of the problem. I pulled off the clutch and pulley for the mower deck, but the pulley that drives the transmission belt seems to be pressed on. There is no keyway showing, but the sleeve below the pulley itself has an indentation that may be (?) pressed into a keyway. The hole in the plate that supports the engine is not big enough to pass the pulley. How does this come apart? Any help would be greatly appreciated.
Thanks |

The main stacked pulley on the bottom of the crank-shaft has a bolt up inside of it that must be removed. Probably a standard 3/4 inch or larger headed bolt. Remove that bolt, and the stacked pulley should slide down and off. The indentation in the tube between the pulleys is what keeps it keyed to the crankshaft, to make it turn and move the tractor, etc. Once you get that stacked pulley off, some work with a sharp ice pick will get the old seal out, and after a bit of clean up, you can carefully tap the new seal into its place. But, if the crank-case seal is leaking, then you must take off the stack pulley, unhook any tubes, wires, etc., remove four engine mounting bolts, and remove the engine. After you get it out, and you have drained the oil and gasoline from the engine and carburetor, turn the engine onto its flywheel, and then locate and remove the bolts that hold the oil pan onto the engine. Remove the oil pan, clean it well, and lay it aside. then clean off any old gasket material from the block area. Before you install the new gasket, put a smooth layer of heavy grease around that area where the gasket goes. Then stick the gasket onto the block, making sure it is in the correct place. then lower the oil pan down onto the block, making sure that the governor shaft goes up into its little "boss" in the oil pan as you lower it into place. Then put in the bolts and tighten them up securely. Tight is "Tight"!
Install the engine, the oil, the fuel line, and if you didn't make any mistakes, it should start and run!
The first one i did took 4 hours. The next ones took 2.5 hours. |
