The previous owner had already removed the balance gears when they “rebuilt” the engine. At first when I heard the balance gears were not reinstalled during assembly I thought that was a bad thing. After doing some research, and seeing what condition the old ones were in, I realized that it was the right thing to do. It's interesting to me that these gears are a common failure point.

It's definitely a good thing that these were not reinstalled

Yikes! those look awful. The bearings in the gears and the studs they ride on wear which, more often then not, causes catastrophic engine failure.

Block, Piston, Crankshaft, & Connecting Rod back from the Machine Shop

Got the Block and Crankshaft back from their respective machine shops and they look great. If anyone in the Houston area (specifically SE Houston) is looking for a machine shop, let me know and I’ll send you their information.







Engine Assembly. Two steps forward, one step back

While the Block and Crank were away, I read the Kohler Engine service manual and knew one of the first things I wanted to do was install the camshaft and check the end play. So that’s exactly what I did when I got the block back. Spec per the manual was .005” - .010”. Unfortunately, even with the .005” shim installed, the end play was in between .014” - .015”. Looks like I need to order a camshaft shim

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
