Tomos A3 engine swap (part3)

Today I thought id do a bit more on my A35 Build. Once I had made sure that both cases were clean and free from metal shavings from the case matching I pushed in the new crank seals.

The next thing to do was install the new bearings on the Top Racing crank. I used a heat gun to get the bearings really hot so they expanded then I used a some pliers to drop them onto the crank.

Below is a shot of the crank with the bearings installed.

Next I needed to heat up the cases so the crank with bearings would fit. I then realised that I would have to remove the seals as I didn't want them to melt.

Above is a shot of the crank installed in one case with the gasket in place.

After heating up the other case I fitted them together and bolted them up. Once the cases had cooled I pushed in the crank seals from the outside.

The next thing to do was to install the gasket and then the piston on a new roller bearing.

More to follow soon!
