Camshaft Bearings
The service bearings for the camshaft are pre-sized and
require no machining after installation. When one bearing
requires replacement it is advisable to replace all three, as
camshaft alignment may be affected if only one bearing is
changed.
The camshaft front and rear bearing are both
approximately 19 mm (3/4 inch) wide, the front one having
an additional oil hole for the rocker arm shaft oil feed, and
the center bearing approximately 16 mm (5/8 inch) wide.
Install the bearings using a replacer in addition to the
adapters previously used. Make sure that the oil holes in
the bearings and cylinder block are correctly aligned before
installation and that the splits in the bearings are upwards
and outwards at 45 degrees to the vertical.
Removal
Remove camshaft following the appropriate procedures in
this section.
1. Remove the flywheel.
2.
Remove the crankshaft rear oil seal carrier.
3. Remove the camshaft bearings.
4. Check all the oil passages to make sure that they are
clear. Apply an oil resistant sealer to the oil gallery
plugs prior to installation.
