Rebuilding The Engine
There comes a time when your engine just won't provide the
performance it did when it was new. When that time comes a
rebuild is in order. Follow the steps below to disassemble, repair
and then reassemble the engine.
Check engine compression.
If there is no compression,
the engine will not start.

Engine Assembly
After completely disassembling the engine, examine the components to determine which parts need to be
replaced. Scratches on the crankshaft, or piston and sleeve are signs that dirt has entered the engine.
Before reassembly, thoroughly clean all parts to make sure they are free of foreign debris. Reassemble the
engine in the reverse order of disassembly (Step 6 - Step 1). Make sure to note the direction of the oil hole
on the rod and the direction of the sleeve as they are critical to proper engine function. As you assemble the
engine, use a small amount of oil on each part to make sure they are well lubricated and move freely. When
you are finished, the new components will need to be broken in. Please turn to 2-7 and follow the
instructions to break in the new components.
After assembling the engine, follow the instructions on these pages to break in and set up your rebuilt engine.
