10.12 BEDKNIFE ADJUSTER SPRING ______________________________________________
For correct operation, the bedknife adjuster spring must be
compressed to 1-7/16 to 1-1/2 in. (3.65 to 3.8 cm).
To adjust the spring compression, loosen or tighten the locknut to get
a distance of 1-7/16 to 1-1/2 in. (3.65 to 3.8 cm).
When you adjust the spring, check the reel to bedknife adjustment.
10.13 BEDKNIFE ADJUSTER TENSION _____________________________________________
Remove the cotter pin. Completely loosen then tighten the slotted nut to
remove the clearance (no end play) between components. Continue to
tighten the nut until next slot in nut aligns to the hole in the bedknife
adjuster rod. Install a new cotter pin.
Check the torque needed to rotate the adjuster rod. Torque must be less
than 24 in. lb. (2 ft. lb.) (2.7 Nm).
When you adjust the nut, check the reel to bedknife adjustment.
10.14 GRINDING THE BEDKNIFE __________________________________________________
Lower the bedknife out of the reel for grinding without completely
removing the bedknife assembly.
1.
Remove the cotter pin, slotted nut, Belleville washer, shim washer
(If needed) and half trunnion from both ends of the reel.
6.
Press down on the adjuster end of the rod to rotate other end of
the adjuster out of the bedknife finger.
7.
Rotate the bedknife backing to access the reel and bedknife.
8.
After you grind the reel and bedknife, assemble the bedknife
using reverse order of removal. Check the adjustment of bedknife
adjuster tension (See Section 10.13), and the reel to bedknife
adjustment (See Section 10.8).
NOTICE
When you tighten the slotted nut more than
necessary, the bedknife adjuster rod will be difficult to
adjust.
