OIL REEL DRIVE CHAIN

MAINTENANCE/SERVICE

REEL AND REEL DRIVE

Reel Drive Chain Lubrication

Lubricate chain daily with a light weight oil (SAE 30). Apply oil to

upper edge of lower chain span (A).

Reel Drive Chain Tension

To tighten reel drive chain:

1. Loosen nuts (A) and (D) securing

reel drive arm to frame.

2. Push pulley (B) up and back until

total chain slack at (C) is 1/2 in.

(13 mm). Be sure chain tension is

sufficient to remove excess belt

play.

3. Tighten nut (A).

4. Adjust reel drive belt tension (see below).

Reel Drive Belt Tension

IMPORTANT: To prolong drive life, do not over-

tighten belt. Belt slippage is used to protect the

reel in an overload situation.

NOTE: Minor belt tension adjustments may be

made without affecting chain tension. For major

adjustments, like after repositioning reel or auger,

adjust chain tension before belt tension.

To adjust reel drive belt tension:

1. Loosen nut (D) on inboard side of right end-

frame

2. Turn nut (E), (on top of right end-frame) on

adjusting bolt until a force of:

NEW BELT - 20 lbs. (80 N)

USED BELT - 12 lbs. (55 N)

deflects belt 1/4 in. (6 mm) at mid-span (F).

3. Tighten nut (D).

4. Re-adjust tension of a new belt after about 5

hours of operation to used belt specifications.

Reel Tines

Keep reel tines in good condition. Straighten or

replace as required.
