4. Position bushing and driver to block and drive the
bushing in position, which is determined by tool
bottoming against the block.
5. Remove tool from bushing. It is possible that the
bushing with minimum I.D. will collapse enough
during installation to slightly seize the installer
arbor. If this happens, remove installer tool using
slide hammer in driver bolt hole or driver handle.
NOTE: This will not damage the bushing
and tool is designed for this purpose, should
it occur.
REPAIRS
Cylinder Conditioning
The performance of the following operation is
contingent upon engine condition at time of repair.
If the cylinder block inspection indicated that the block
was suitable for continued use except for out-of-round or
tapered cylinders, they can be conditioned by honing or
boring.
If the cylinders were found to have less than .005" taper
or wear they can be conditioned with a hone and fitted
with the high limit standard size piston. A cylinder bore
of less then .005" wear or taper may not entirely clean
up when fitted to a high limit piston. If it is desired to
entirely clean up the bore in these cases, it will be
necessary to rebore for an oversize piston. If more than

.005" taper or wear, they should be bored and honed to
the smallest oversize that will permit complete
resurfacing of all cylinders.
When pistons are being fitted and honing is not
necessary, cylinder bores may be cleaned with a hot
water and detergent wash. After cleaning, the cylinder
bores should be swabbed several times with light engine
