REEL BEARING ___________________________________________________________

Any radial play or excessive end play indicates bad
bearings, a weak tension spring or a backed off nut.
1. Check bearing housing mounting hardware. Tighten
or replace components as required. Carefully clean
threads with degreaser.
2. Apply a medium strength grade of Loctite to nut (P),
then thread nut onto the reel shaft until the nut is
1-27/32" (46 mm) from the end of the reel shaft.
3. Fill reel bearing housings with NLGI - Grade O
grease after adjusting spring.
9.6

BEDKNIFE ADJUSTER SPRING ______________________________________________

For proper operation, bedknife adjuster spring should be
compressed to a dimension of 1-7/16 - 1-1/2 in. (36.5-38
mm).
To adjust spring compression, loosen or tighten nut (R) to
obtain a distance of 1-7/16 - 1-1/2 in. (36.5-38 mm).
After adjusting spring, check reel to bedknife adjustment.
9.7

BEDKNIFE ADJUSTER TENSION _____________________________________________

NOTICE
Overtightening slotted nut (S) will make bedknife
adjuster rod (T) difficult to adjust.
Remove cotter pin (U) and fully loosen, then tighten
slotted nut (S) to remove clearance (no end play)
between components. Continue to tighten nut until next
slot in nut aligns with hole in bedknife adjuster rod (T).
Install new cotter pin.
Check torque required to rotate adjuster rod (T).
Maximum torque should be 24 in. lb. (2 ft. lb.) (2.7 Nm).
9.8

GRINDING BEDKNIFE ______________________________________________________

Bedknife can be lowered out of the reel for grinding
without completly removing the bedknife assembly.
1. Remove cotter pin (U), slotted nut (S), bellville
washer (V), shim washer (W-If required), and half
trunnion (X). See Figure 9G
4. Press down on adjuster end of rod (T) to rotate other
end of the adjuster out of the bedknife finger.

adjuster tension (Section 9.7), and reel to bedknife
adjustment (Section 8.3).
