Base and gasket replacement
Great repair, total time for repair 45 minutes. Word of caution, the drive shaft oil requires alignment for ease of installation. Use a little grease to hold shaft in place. So easy a cave man could do it..

shipping was a problem
I ordered the parts with the promise and 'payment' of two day delivery - instead they came five days later. I needed help to install the parts which was delayed for over a week. You were recommended by the installer who has had great success with you. I now need a drive belt however I ordered it from another source. I realize that delivery is beyond your control once it leaves your warehouse but I need the belt as soon as possible.

Oil Leak

Tool Type

Difficulty
Medium
Time
More than 2 hours
Tools Used
Screwdriver, Pliers, Socket set, Wrench Set, Nutdriver, Impact wrench to remove electric clutch.
Removed Engine, removed oil pump, removed oil pan, spent a great deal of time removing the old gasket taking care to prevent pieces from entering the engine. Removed seal, reinstalled new seal, reinstalled new gasket, replaced oil pan, replaced oil pump and o-ring, reinstalled engine, installed new drive belt, started and checked for leaks and proper operating. Everything fit perfectly and now with a new dry drive belt the mower is once again moving forward and backward at the desired speed without the essence of burning belt and oil.
A note of caution, when reinstalling the oil pan over the non chamfered crankshaft the seal is very easily damaged. It requires assistance in the form of carefully manipulating the seal over the crankshaft. I used a jewelers hex screwdriver but any small blunt object to guide the seal without cutting would suffice. Also scribing a reference mark on the the governor arm and shaft ensures it goes back on in the proper position. If you forget to do this you must reference technical data for proper installation to prevent engine overspeed damage. Simple procedure but too long to write in space provided.
