Reel Bearing Service and Adjustment
1. Adjust the bedknife so it is not in contact with the reel.
2. Reel bearing drag should be 4 to 7 in-lb. This can be
measured with a torque wrench (Fig. 5). If bearing drag
does not meet above specification, adjust the reel bear­
ings.
NOTE: If you do not have an inch-pound torque wrench,
do steps 1 - 3 under Reel Bearing Adjustment below.
Reel Bearing Adjustment
1. Remove mounting nuts from counterbalance end cap
and remove end cap from the mounting studs (Fig. 6).

Do not use your hand to prevent reel from
while servicing; this can result in
personal in ury. Use a 1/2 in. thick x 3 in. wide
x 8 in. long piece of hardwood inserted into
front of cutting unit between reel blades.
CAUTION
2. Loosen large reel bearing adjustment nut (Fig. 7). Tap
on the head of the hex head bolt on the end of the reel
shaft with a small hammer, until end play of the reel shaft
can be felt.
NOTE: If reel bearings will not hold adjustment during
operation, loosen adjustment nut, tighten reel shaft
spline nut on right hand end of reel shaft to a torque of
40 to 60 ft-lb, then adjust reel bearings.
3. Tighten reel bearing adjustment nut until there is no
reel shaft end play, then tighten an additional 1/16 to 1/8
turn. Be certain to remove all end play, but do not
over-tighten.
NOTE: Adjustment nut must have enough resistance
against reel shaft threads to retain bearing adjustment.
Replace adjustment nut if necessary.
4. Check rolling torque with an inch-pound torque
wrench (Fig. 7). Reel bearing rolling torque should not
exceed 7 in-lb. Repeat steps 2, 3 and 4 if necessary.
5. If bearings require replacement, see Reel Removal
and Bearing Replacement in the Repairs section of this
chapter.
