Rod broke ruining the case and camshaft
dissembled ordered repair parts, piston ,upper case, rod, camshaft, seal kit, and motor maintenance CD
The camshaft first provided did not have the compression release device on it and the cam lobe position was all wrong for the model engine I had. .
Parts Select provided me with the proper cam Shaft. Removed engine from mower (Scag Freedom Z) 15 minutes, drained oil, flipped upside down removed bottom case, removed wrong cam shaft, reinstall new valve lifters, camshaft with decompression release on it matching dots on crankshaft. Used paint brush to coat all parts heavily with motor oil.
Do not put sealant on case gasket,(it might change crankshaft end play), retorqued bolt in alternating pattern, placed nylon pipe tape on drain plug threads, and reinstalled engine on mower. It started instantly and ran extremely smooth with no oil burn or vibration.
I am very happy with the support and quick mshipping Parts Select provided..
