Lauson TLC

In 2001, my friend Pat Monahan told me about an engine he had acquired about 10 years prior that was all apart in a couple of boxes. He didn't know much about it other than it was a no-sale at an auction. He took it rather than see it get scrapped.

I went to look at it, as I was looking for another project to work on. He said if I would restore it and get it running, he would give it to me. It is a Lauson Model TLC crank-start (photos below).

The engine was totally disassembled and other than dirty, the parts and pieces were in good shape. He had stored it away in a dry place, thankfully.

It took about three months to get everything cleaned, reassembled and, what few parts missing, fabricated. The funny thing was that it didn't have any nuts, bolts, screws or washers in the mix of parts.

For many small reasons, I wasn't able to get it running for another three months after much "de-bugging." But it finally has given in and runs quite well now.

This engine is started by a crank on the PTO side of the engine. It is all cast iron with New Departure ball bearings on both sides of the crankshaft, insert rod bearings, with a 2-1/4-by-2-1/4-inch bore and stroke. It was built in May 1942, has serial no. 74442 and specification no. 2123. I even found a NOS muffler by accident.
