VALVESEAT
Renew the valve seats in the cylinder head using avalve seat cutter.
NOTE: lf guides are worn (see page 6-26), replace
them {see page 6-27) before cutting the valve seats.
Carefully cut a 45" seat, removing only enoughmaterial to 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 accordingly.
Make one more very light pass with the 45o cutter toremove any possible burrs caused by the other cut-rers.
V8lv6 S€at Width (lntake and Exhaustl:
Standard {New}: 1.25 - 1.55 mm {0.0/t{, - 0.061 in}
S€rvice Limit: 2.0 mm 10.08 in)
After resurfacing the seat, inspect for even valveseating: Apply Prussian Blue compound to the valveface. Insert the valve in its original location in thehead, then lift it and snap it closed against the seatseveral times.
PRUSSIAN BLUE COMPOUNO
6-29
o.The actual valve seating surface, as shown by theblue 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 at up, then one more cut with the 45. cutterto restore seat width.
NOTE: The final cut should always be made with
the 45" cutter.
Insert intake and exhaust valves in the head andmeasure valve stem installed height.

Clearance
1. Remove the connecting rod cap and bearing half.2. Clean the crankshaft rod journal and bearing halfwith a clean shop towel.
3. Place the plastigage across the rod journal.
4. Reinstall the bearing half and cap, and torque thenuts (818C5 engine: see page 7-19).
81881 engine:31 N.m (3.2 kgnm,23 tbf.ftl

NOTE: Do not rotate the crankshaft during inspection.

lf the plastigage measures too wjde or too narrow,remove the upper half of the bearjng, install a new,complete bearing with the same color code (select
the color as shown in the rig ht column), andrecheck the clearance.
CAUTION: Do not file, shim, or scrape the bearingor the caps to adiust clearance.
It the plastigage shows the clearance is still incorrect,try the next larger or smaller bearing (the color listedabove or below that one), and check clearance again.
NOTEr It the proper clearance cannot be obtainedby using the appropriate larger or smaller bearings,replace the crankshaft and stan over.
Selection
CAUTION: lf the codes are indecipherable because ofan accumulation of dirt and dust, do not scrub themwith a wire brush or scraper. Clean them only with sol-vent or delergent.
Connecting Rod Code Location
A number has been stamped on the side of each con-necting rod as a code for the size of the big end. Use it,and the letters stamped on the crank lcodes for rod iour-nal size), to choose the correct bearinqs.
