• Use a 50:50 mixture of diesel fuel and engine

oil as a honing fluid.

• Use a 300-grit hone at 300 - 1200 rpm

(Figure 6-82).

Figure 6-82

IMPORTANT

Solvents will not adequately remove honing

residue, resulting in premature piston and

ring wear. Always wash cylinders using hot,

soapy water.

• When honing is completed, wash the cylinder

block with hot water and soap. The cylinder wall

is adequately cleaned when a white rag wiped

in cylinder comes out clean. Use brushes to

clean all passages and crevices. Rinse with hot

water and dry with compressed air. Apply clean

engine oil to all steel surfaces to prevent

rusting.

Reassembly of Crankshaft and

Piston Components

Notes:

• Proceed slowly. Make no forced assemblies

unless a pressing operation is called for. All

parts must be perfectly clean and lightly

lubricated when assembled.

• Use new gaskets, seals and O-rings during

assembly.

• Liberally apply clean engine oil to all internal

parts during assembly.

• All fasteners should be tightened to a given

torque. If a special torque is not provided in the

Special Torque Chart on page 6-14, tighten to

standard torque specifications. See Tightening

Torques for Standard Bolts and Nuts on

page 4-22.

CAUTION

Do not allow the honing tool to operate

in one position for any length of time.

Damage to the cylinder wall will occur.

Keep the tool in constant up-and-down

motion.
