Desirable Crosshatch Pattern Obtained with a Cylinder Hone
After all honing operations are complete,
thoroughly wash the bores with soap, hot water
and a stiff brush to remove all traces of grit.
Kerosene or other solvents will not remove the
grit. Rinse the block with clean, clear water and
dry with compressed air.
Oiling Bores
If not, the bores must be rewashed. As
soon as the bores have dried, lubricate with
engine oil immediately to prevent rust. This
completes the honing operation.
PISTONS
Check the pistons for excessive ring groove
wear, and replace any that exceed the allowable
limits in our Limits and Clearance Data.
The cylinder walls and pistons must be perfectly
clean and dry when fitting pistons in the
cylinder bores. Pistons should be fitted with the
block °- and piston at room temperature 20.0
21.0 °C (68 °-70 °F).
Cleaning Bores
PISTON FIT ON STANDARD PISTONS
(with 2.3 to 4.5 kg (5 to 10#) Pull)
TMD series 0.08mm (.003")
When you have finished cleaning the
block, run a clean, dry paper towel through
the bores. The paper towel should come out
clean.
Check the piston fit in the bore using a half-inch
wide strip of feeler stock, of the thickness
specified in the Limits and Clearance Chart, the
feeler being attached to a small scale of approximately
7 kg (15 Lbs.) capacity.
