5.1.18 Thread locking adhesives Fel-Pro Pro-Lock "Nut-Type" or Loctite Threadlocker
"242" are used on the following:
a) All belt drive pulley setscrews.
b) OPC lever setscrews.
c) Pulley retaining bolt in end of engine crankshaft.
d) Fuel tank bulkhead fitting threads.
Adhesives such as Loctite "RC/609" or "RC/680" or Fel-Pro Pro-Lock "Retaining"
or "Retaining II" are used on the following:
a) OPC lever hubs and cross-shaft.
NOTE: When applying any locking adhesives, care must be used not to bond

5.2 ADJUSTMENTS

5.2.1 Adjusting cutting height with blade spacers.
Blades may be adjusted for cutting height by using the four 1/4" (.64 cm) spacers
found on the blade spindle bolts (factory setting is two above and two below). This
allows a 1" (2.5 cm) range in 1/4" (.64 cm) increments of cutting height in any axle
position. The same number of blade spacers must be used on all blades to achieve
a level cut (two above and two below, one above and three below, etc.).
For the best cut and discharge, place a minimum of two spacers between the
blade and spindle shaft.
For the highest quality cut, place all four spacers between the blade and the
spindle shaft.
