Valve Seats
Reconditioning
lf the guides are worn (see page 6-25), replace them (seepage e25) before reconditioning the valve seats.
1. Renew the valve seats in the cylinder head using avalve seat cutter.
Carefully cut a 45o seat, removing only enoughmaterialto ensure a smooth and concentric seat.
Bevel the upper edge of the seat with the 30. cutterand the lower edge of the seat with the 60" cutter.Check width of seat and adjust acco.dingly.
Make one more very light pass with the 45o cutter toremove any possible burrs caused bv the other cut-ters.
Valve Seat Width (lntake and Exhaust):
Standard {N.w}: 1.25 - 1.55 mm (0.049 - 0.051 in)Servica Limit: 2.0 mm (0.08 in)

5. After resurfacing the seat, inspect for even valve
seating: Apply Prussian Blue compound to the valve
face, and insert the valve in its original location in
the head, then lift it and snap it closed against the
seat several times.

PRUSSIAN
The actual valve seating surface, as shown by the
blue compound, should be centered on the seat.. lf it is too high (closer to the valve stem), you
must make a second cut with the 60" cutter tomove it down, then one more cut with the 45"
cutter to restore seat width.
. lf it is too low (closer to the valve edge), you
must make a second cut with the 30. cutter tomove it up, then one more cut with the 45. cutter
to restore seat width.
NOTE: The final cut should alwavs be made withthe 45" cutter,
Insert the intake and exhaust valves in the head,
and measure valve stem installed heioht.

End Play
1. Measure the connecting rod end play with a feeler
gauge.
Connecting Rod End Play:
Stsndard (Nsw): 0.15 - 0.30 mm
{0.006 - 0.012 in)
Service Limit: 0./t0 mm 10.016 in)
2. lf the connecting rod end play is out-of-tolerance,
install a new connecting rod.
lf it is still out-of-tolerance, replace the crankshaft
{see pages 7-9 and 7-20).

3. Push the crankshaft firmly away from the dial indi-
cator, and zero the dial against the end of the
crankshaft. Then pull the crankshaft firmly back
toward the indicator; the dial reading should not
exceed the service limit.
Crankshaft End Play:
Stand.rd (New): 0.10 - 0,35 mm(0.004 - 0.014 inl
Service Limit: 0.45 mm (0.018 inl
4. lf end play is excessive, inspect the thrust washers
and thrust surface on the crankshaft. Reolace oans as
necessary. Thrust washer thickness is fixed and
must not be changed either by grinding or shim-
mrng.
