8.7 BACKLAPPING AND GRINDING ______________________________________________
Check for damage to the bedknife and reel blades.
Refer to (Section 7.2).
1. Determine if backlapping or grinding will restore the
proper cutting edge.
2. For optimum performance use a bedknife grinder to
touch-up the blade then reassemble and adjust the
bedknife to the reel as described in (Section 7.2).
3. Remove shaft cover from right side of reel and
assemble a 3/8-24 bolt and locknut to the end of the
shaft.
a. Apply lapping compound with a long handle
brush along the entire length of the reel, (180 grit
is recommended, Section 2.6).
b. Continue lapping and at the same time make a
fine adjustment on the reel and bedknife until
there is a uniform clearance along the full length
of the cutting edges.
4. Carefully and thoroughly remove all lapping
compound from reel and bedknife before running
the reel in forward direction.
CAUTION: Unless you have the proper
training, tools and experience, DO NOT
attempt to mount a tire on a rim. Improper
mounting can produce an explosion that may
result in serious injury.
