Disassembly Part 2




I commissioned Lawrence Swanz from Zimmerman, MN to build me a gantry crane of sufficient size and strength to remove and replace the various parts from the engine. Here Allen Kroneman, Eric Buldoc, Colin Hall and Lawrence are assembling the gantry crane.

Once assemble on the floor, we raised the crane.

Once the crane was assembled and ready for service, Jim Evans and Lawrence had a race to see who could take off the first bolt. I think Lawrence won, but it was really too close to call.

Brain Patterson and Nick Feltus come down to help me on my 14HP Minneapolis project, but we couldn’t resist getting something done with the 40 as well so we decided to remove the rear bunkers.

The bunkers came off real easy. We moved them off to the side for now.

I received a few pictures from Lawrence today. Unloading the motor into his shop.

Easy does it.


Ready for Lawrence to tear into the motor.




Lawrence and Nicholas came down to work on the gantry crane and to help with the dismantling some more. Here Nicholas stands behind the Gaar Scott before work started. Our goal for the day was to remove the wheels, differential, intermediate gear, intermediate shaft and the rear axle.

Lawrence had decided that the gantry needed to be stabilized a bit. He prefabricated the additional bracing in his shop. Here he is installing some of the additional bracing. However his work on the gantry was relatively short lived.

Here Oly Maas and Nick Feltas are determining the best way to remove the right wheel.

As the rest of the crew started to remove the wheels, Lawrence decided the gantry would serve its purpose in its current condition as he was overly anxious to help our on the Gaar Scott. Here Nicholas and Lawrence adjust the height on each side of the right wheel to keep it straight while Oly and Nick jack off horizontally.

The wheel is off. What a relief. We were concerned over getting the hub retaining pin out, but it turned out that there were two of them and they were only finger tight.

The left wheel actually came off much easier. Here the differential is exposed with Jerred and Nicholas inspecting the condition of the differential.

Rob Johnson stopped over to inspect the progress. Here Nick, Rob, Lawrence and Nicholas carefully remove the intermediate gear.

Next we turned our attention to removing the intermediate shaft. This proved to be a little more difficult then expected. It was a very tight fit. After some grunting and moaning the shaft was loose. Oly and Nick remove the shaft with Jerred inspecting their progress.

Removing the axle proved to be the most troublesome of the day. It was an extremely tight fit as some sort of metal (I am told it is “spelter”, a form of zinc) was used to secure the axle bearing to the wing sheets. After a lot of chiseling and prying, the axle finally let loose and Nick and Lawrence guide it out of its resting place.

At days end we had accomplished what we set out to do. Thanks go to Oly Maas, Nick Feltas, Lawrence and Nicholas for all their help and a fun and rewarding day.
