limits, the glaze and ridge must be removed by working a hone up and down the full length of the liner a few
times.
Place the liner in a fixture (a scrap cylinder block makes an excellent honing fixture). However, if it is
necessary to hone a liner in the cylinder block that is to be used in building up the engine, the engine must be
dismantled and then, after honing, the cylinder block and other parts must be thoroughly cleaned to ensure that
all abrasive material is removed.
The hone J 5902-01, equipped with 120-grit stones J 5902-14, should be worked up and down (at 300-400 rpm)
the full length of the liner a few times in a criss-cross pattern that produces hone marks on a 45axis.
After the liner has been honed, remove it from the fixture and clean it thoroughly. Then dry it with compressed
air and check the entire surface for burrs.
After honing, the liner must conform to the same limits on taper and out-of- round as a new liner, and the
piston- to-liner clearance must be within the specified limits (Specifications).
Install the liner (new or used) in the proper bore of the cylinder block and measure the inside diameter at the
various points shown in Fig. 5. Use cylinder bore gage J 5347-01 (Fig. 6), which has a dial indicator calibrated
in 0.0001-inch increments. Set the cylinder bore gage on zero in master ring gage J 8385-01. Also check the
liner for taper and out-of-round.
NOTE
Dial bore gage, master setting fixture J 23059-01 may be used in place of the
master ring gage.
The piston-liner clearance must be within the specified limits. Also, the taper must not exceed 0.002 inch and
the out-of-round must not exceed 0.003 inch on a used liner. The taper must not exceed 0.001 inch and the
out-of- round must not exceed 0.002 inch on a new liner.
New service liners have an inside diameter of 3.8752 to 3.8767 inches.
Fitting Cylinder Liner in Block Bore
1. Wipe the inside and outside of the liner clean and make sure the block bore and counterbore are clean.
