Readings must be within limits given in table 4-52. The

letter L shows a loose fit.

given limits, throw away part and get a new one.

Intake valves (1) and exhaust valves (2) were tagged

so fit of each valve stem can be measured in valve guide

it was taken from.

Measure and note outside diameter of stem of three exhaust valves (2).

2.

Measure and note inside diameter of three exhaust valve guides (3) 1/8 to 1/4

inch from each end of guide.

If diameter is different at each end of guide,

note biggest diameter.
