Small Engines (Lawn Mowers, etc.): 460700 With To High Compression, dowel pins, crankshaft seal

Question
Hi John,

So my question has changed.  My compression is too high to get the engine turning over.  I have adjusted valves, changed starters, lapped valves, and check the fly wheel key.  All these are good.  You stated that the only thing left is the Cam Lobe is Worn and the Cam will have to be Replaced.  

That sounds like it is correct.  So, what in the world is the easiest way to open the engine?  Can I split it while keeping the top half all intact, and just pull the cam out, or do I need to completely disassemble (including removing pistons and such)?

Thanks

Jason

Answer
Hi Again Jason:

All that is Requires is for the Oil Pan/Sump to be Removed from the Engine and then the Cam can be Removed. Make Sure the Engine is Set at TDC for Removing the Cam. This will Take the Pressure of the Valves Off the Tappets and Allow the Cam to Slid Out and a New Cam to Slide Back in. **This is a Simple Process. Drain the Oil and Remove the Engine from the Frame to the Work Bench with the Oil Pan Facing Up. I have a Wooden Rest that was Especially Made to Hold the Engine when in this Position. Using Fine Sand Paper, Remove ALL the Rust and Debris from the Crankshaft. Remove the Oil Pan Bolts. After All the Oil Pan Bolts are Removed; Tap Lightly on the Sides of the Oil Pan to Loosen it from the Dowel Pins. When the Oil Pan is Removed, you can See the Governor Resting on Top of the Cam Gear. Lift Off the Governor and then Lift the Old Cam Out After you have Set the Engine Timing Mark on the Crankshaft Gear with the Timing Mark on the Cam. Set the New Cam in and be Sure the Timing Marks are aligned. Check the Engine Block for Debris and Wipe the Inside of the Block With a Rag, Until Clean. Set the Governor So it will be Resting on the Governor Shaft and Carefully Replace the Oil Pan. Remember to Replace the Oil Pan Gasket. If the Crankshaft Seal Was Not Leaking, then Leave it Alone. It Should be OK. You can Easily Replace it While Mounted on the Machine if Required Later. Make Sure the Governor Stays in Contact with the Governor Shaft while Replacing the Oil Pan. Re - Mount the Engine to the Machine. Refill With Oil. These Instructions are Basic. Your Internal Governor May Differ. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
