General

Refer to Maintenance Scheduling → Regular Service Intervals → Regular Service Intervals: 2006 Police Models. The chaincase lubricant should be drained and refilled with fresh lubricant at specified intervals.

NOTE

When checking the chaincase lubricant, motorcycle should be standing STRAIGHT UP, not leaning on the jiffy stand. Keep motorcycle upright for a short period of time to equalize lubricant level in the chaincase compartment.

Check Lubricant Level

1.	Ride motorcycle until engine is warmed up to normal operating temperature.
2.	When the engine reaches normal operating temperature, turn the engine off and position motorcycle STRAIGHT UP and LEVEL.
3.	See Figure 1. Remove five screws (4) (with captive washers) to free clutch inspection cover (2) from primary chaincase cover.
4.	Remove gasket and discard.
5.	See Figure 2. With the vehicle standing upright, not leaning on the jiffy stand, the lubricant level must be visible in the bottom of the chaincase and must not be higher than the diaphragm spring.
6.	Pour the proper amount and type of primary chaincase lubricant in through the clutch inspection cover opening, if required.
	NOTICE Do not overfill the primary chaincase with lubricant. Overfilling can cause rough clutch engagement, incomplete disengagement, clutch drag and/or difficulty in finding neutral at engine idle. (00199b)
7.	Refer to procedure in Changing Chaincase Lubricant to install gasket and clutch inspection cover. NOTE Use only GENUINE Harley-Davidson FORMULA+ TRANSMISSION AND PRIMARY CHAINCASE LUBRICANT (Part No. 99851-05 quart).

1	Primary chain inspection cover
2	Clutch inspection cover
3	Drain plug 36-60 in-lbs (4.1-6.8 Nm)
4	Screws with captive washer
5	Clutch cover torque sequence

Changing Chaincase Lubricant

NOTICE

When draining or adding lubricant, do not allow dirt, debris or other contaminants to enter the engine. (00198a)

1.	Ride motorcycle until engine is warmed up to normal operating temperature.
2.	See Figure 1. Remove magnetic drain plug (3) at bottom of primary chaincase cover. Drain lubricant into suitable container. NOTE Dispose of chaincase lubricant in accordance with local regulations.
3.	Remove five screws (4) (with captive washers) to free clutch inspection cover (2) from primary chaincase cover.
4.	Clean drain plug. Remove debris from magnet and inspect o-ring for cuts tears or signs of deterioration. Replace as necessary. Install drain plug and tighten to 4.1–8.6 N·m (36–60 in-lbs). If plug has accumulated excess debris, inspect the condition of chaincase components.
5.	Pour approximately 32 oz. (946.35 ml) of GENUINE Harley-Davidson FORMULA+ TRANSMISSION AND PRIMARY CHAINCASE LUBRICANT (Part No. 99851-05 quart) in through the clutch inspection cover opening.
6.	See Figure 2. With the vehicle standing upright, not leaning on the jiffy stand, the lubricant level must not be higher than the spring. NOTE Use only GENUINE Harley-Davidson FORMULA+ TRANSMISSION AND PRIMARY CHAINCASE LUBRICANT (Part No. 99851-05 quart).
	NOTICE Do not overfill the primary chaincase with lubricant. Overfilling can cause rough clutch engagement, incomplete disengagement, clutch drag and/or difficulty in finding neutral at engine idle. (00199b) NOTICE When draining or adding lubricant, do not allow dirt, debris or other contaminants to enter the engine. (00198a) WARNING Be sure that no lubricants or fluids get on tires, wheels or brakes when changing fluid. Traction can be adversely affected, which could result in loss of control of the motorcycle and death or serious injury. (00047d)
7.	To avoid punching holes in the clutch inspection cover gasket or enlarging existing holes, install clutch inspection cover and new gasket as follows: a. Align the triangular shaped hole in the gasket with the top hole in the clutch inspection cover. Be sure the rubber molding and the words "towards clutch" face the motorcycle. b. Insert screw (with captive washer) through clutch inspection cover and carefully thread it all the way through triangular shaped hole in gasket. Do not push screw through hole. c. Hang the clutch inspection cover on the primary chaincase cover flange by starting the top cover screw. d. Start the remaining four screws (with captive washers). e. Attach clutch inspection cover using five screws (with captive washers). Tighten to 9.5–12.2 N·m (84–108 in-lbs). Follow torque sequence shown in Figure 1.
