CYLINDER INSTALLATION - PISTON IN
CYLINDER
The piston and cylinder can be installed onto the engine
as an assembly. Using this method, special tools: PV-
43570–1 (Piston Ring Compressor Pliers) and PA-51457
(Piston Ring Band) can be used to compress the rings
when installing the piston into the cylinder.
1. Clean the cylinder bore and piston assembly. Apply a
light film of clean engine oil to the cylinder bore and
piston.
2. Install a new piston circlip into the MAG (stator) side
of piston with the gap at the 12:00 position.
NOTE
An arrow mark denotes the MAG (stator) side of the
piston.
3. Verify all ring gaps are correctly located on the piston.
4. Carefully install the Piston Ring Band (PA-51457)
around all of the rings on the piston. Secure the band
with the Compressor Pliers (PV-43570–1).
NOTE
Orientate band tool so that open end is opposite the
MAG side of the piston.
