FUJI 25 REBUILD

Here's the engine as received from Gerald.

Here we have the engine all stripped down and ready for cleaning and assessing.

First step is to clean the crankcase and front housing and reassemble the front housing with new bearings and a freshly made spinner nut that doesn't look quite so grotesque.

Next up is to clean and rebore the cylinder assembly as this poor old thing has no compression.

Having had a good look at this portion of the engine we will also need a new conrod and gudgeon pin.

Here's the new  rod all finished and ready to install.

Progress so far.........

 

Now it's onto the new piston and refinishing of the cylinder liner.

Here we have the new piston blank all machined up and ready for final fitting to the cylinder liner which has also been rebored and finish lapped.

Now we will lap the new piston to size and final fit it to the cylinder liner ready for reassembly and test running.

New piston all finished and ready to reassemble to the rest of the engine.

All done and ready for a test run.........

Now where's that fuel gone?
