Reassembly

General

NOTE: Make sure the engine is assembled using all

specified torque values, tightening sequences,

and clearances. Failure to observe

specifications could cause severe engine wear

or damage. Always use new gaskets. Apply a

small amount of oil to the threads of critical

fasteners before assembly, unless a Sealant or

Loctite

is specified or pre-applied.

Make sure all traces of any cleaner are removed before

the engine is assembled and placed into operation.

Even small amounts of these cleaners can quickly

break down the lubricating properties of engine oil.

Check the oil pan, crankcase, cylinder heads, and

valve covers to be certain that all old sealing material

has been removed. Use gasket remover, lacquer

thinner, or paint remover to remove any remaining

traces. Clean the surfaces with isopropyl alcohol,

acetone, lacquer thinner, or electrical contact cleaner.

Figure 11-1. Seal Bore of Crankcase.

2. Apply a light coat of engine oil to the outside

diameter of the oil seal.

3. Drive the oil seal into the crankcase using a seal

driver. Make sure the oil seal is installed straight

and true in the bore and the tool bottoms against

the crankcase. See Figure 11-2.
