1970 And Earlier Adjustments
1979 To 1984 Adjustments



Periodic adjustment of the clutch is required every 2000 miles to compensate for lining wear. The need for attention to clutch and controls will also be indicated by the clutch slipping under load, or dragging in released position. In any case, the first thing to be checked is the adjustment of clutch controls.
(Figure 4-3)

1. Loosen control coil adjuster locknut (13) and turn adjuster (15) inward until there is a large amount of free play at hand lever on handlebar.
2. Remove access plug (1) from primary chain compartment cover.
3. Loosen adjusting screw locknut (3) and turn screw (5) inward until it becomes harder to turn (starts to release the clutch) and continue turning (about 2 more turns) to be sure clutch is disengaged.
4. Adjust all free play out of control cable by turning adjuster (15) Outward. Do not put any tension on cable. With aH slack in cable eliminated (no play at hand lever) tighten the coil adjuster locknut (13). This is the correct cable adjustment.
5. The clutch release adjustment should then be made with the clutch adjusting screw as follows: Loosen the locknut (3) and back off the adjusting screw (5) until the clutch is engaged (screw turns easier), then turn screw inward until the point where free play has just been eliminated. From this point, turn the adjusting screw outward 1/4 to 1/2 turn to establish correct free play, and tighten locknut. Check cable free play at clutch hand lever. Hand lever should have 1/8 free play. If incorrect, adjust sleeve and tighten locknut.
If the clutch continues to slip under load or drag in released position, clutch springs may need adjusting or release mechanism may be defective.

On Electric Start XLH Models, remove battery cover and disconnect ground wire from battery (-) terminal to prevent accidental starter operation.

Remove left footrest and rear brake foot lever. Place an oil drain pan under clutch and remove front chain cover screws,cover and gasket.
With cover removed, the clutch releasing disc (4), six spring tension adjusting nuts (3), stud retainers (2) and retainer nuts (1) are in view.
If required, adjust each of the six nuts one half turn at a time after removing retainer nuts (1) and retainers.
Tightening the spring tension adjusting nut moves the releasing disc closer to the outside surface of the outside surface of the outer drive plate. This increases the clutch spring pressure on the clutch plates through pressure plate studs.
Outer surface of releasing disc should measure 11/32 in. from the outer surface of the outer drive plate for normal clutch spring tension adjustment. When increasing spring tension, do not diminish above distance to less than 5/16 in. or clutch may not release.


Clutch spring tension is determined by the length of six stud spacers. To correct clutch slippage caused by worn clutch drive plate linings, a set of shorter than standard spacers can be installed.
Under no circumstances should clearance between releasing disc and outer drive plate be allowed to go under minimum 1/8 in. dimension shown. All spacers should be equal in length.
