Section 9

Inspection and Reconditioning

This section covers the operation, inspection, and

repair/reconditioning of major internal engine

components. The following components are not

covered in this section. They are covered in sections of

their own:

Air Cleaner, Section 4

Carburetor & External Governor, Section 5

Ignition, Charging & Electric Starter, Section 7

Clean all parts thoroughly. Only clean parts can be

accurately inspected and gauged for wear or damage.

There are many commercially available cleaners

that will quickly remove grease, oil, and grime from

engine parts. When such a cleaner is used, follow the

manufacturer’s instructions and safety precautions

carefully. Make sure all traces of the cleaner are

removed before the engine is reassembled and placed

into operation. Even small amounts of these cleaners

can quickly break down the lubricating properties of

engine oil.

Use an aerosol gasket remover, paint stripper, or

lacquer thinner to remove any old gasket material.

Apply the solvent, allow time for it to work, and

then brush the surface with a brassȱȱǯȱĞȱ

all old material is removed, clean the surface with

isopropyl alcohol, lacquer thinner, or aerosol electrical

contact cleaner. Do not scrape the surfaces, as any

scratches, nicks, or burrs can result in leaks. See

Service Bulletin 252 for further information.

Refer to A Guide to Engine Rebuilding (TP-2150-A)

for additional information. Measurement Guide

(TP-2159-B) and Engine Inspection Data Record

(TP-2435) are also available; use these to record

inspection results.

regrind the crankpin to 0.25 mm (0.010 in.) undersize.

If reground, a 0.25 mm (0.010 in.) undersize

connecting rod (big end) must then be used to achieve

proper running clearance. Measure the crankpin for

size, taper, and out-of-round.
