Cylinder Liners
Removal
4. Carefully fit the rubber section of the tool fully into
the cylinder liner, positioning the studs supplied with
the tool diagonally across a pair of head bolt-holes.

• It is not necessary (or possible) to fully extract
the liner using this tool. Once the seal is
broken, the tool must be removed and the
liner extracted by hand.
8. Turn the locking nut anti clockwise to release the
liner.
9. Once the seal on the liner is released, remove the
tool and manually remove the liner.

1. Mark each liner to identify correct orientation and
the cylinder number from which it has been
removed.
2. Turn the crankshaft until the piston in the liner to be
removed is at the bottom of its stroke.
Note:
• If an accessory big bore kit is fitted, replace the
centre section of tool T3880061 with tool
T3880121. The removal procedure is identical
for either size cylinder liners.
3. Check that the locking nut on tool 13880061 is
loose, then fully unscrew the extraction nut.
The cylinder liners and pistons are made of aluminium
alloy and can therefore be easily damaged. Handle the
cylinder liner and piston with care, ensuring the internal
bore of the liner and the piston skirt are not scratched.
