General

Refer to Maintenance Scheduling → Regular Service Intervals → Regular Service Intervals: 2007 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 (2) (with captive washers) to free clutch inspection cover (1) from primary chaincase cover.
4.	Remove gasket and discard.
5.	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)
6.	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).

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 and Figure 3. Remove magnetic drain plug at bottom of primary chaincase cover. Drain lubricant into suitable container. NOTE Dispose of chaincase lubricant in accordance with local regulations.
3.	See Figure 2. Remove five screws (with captive washers) to free clutch inspection cover 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 19–28.5 N·m (14–21 ft-lbs). If plug has accumulated excess debris, inspect the condition of chaincase components.
5.	Pour the appropriate amount of GENUINE Harley-Davidson FORMULA+ TRANSMISSION AND PRIMARY CHAINCASE LUBRICANT (Part No. 99851-05 quart) in through the clutch inspection cover opening. A wet primary change will require 38 oz. (1177 ml). A dry fill after complete disassembly of the primary requires 45 oz. (1330 ml). 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)
6.	Install clutch inspection cover and new gasket as follows: a. Thoroughly wipe all lubricant from the cover mounting surface and groove in chaincase. b. Position gasket in groove in primary chaincase cover and press each of the nubs on gasket into the groove. The nubs will retain the seal in position. c. Insert screw (with captive washer) through clutch inspection cover and thread it into the top cover screw hole. d. Start the remaining four screws (with captive washers). e. Tighten screws to 9.5–12.2 N·m (84–108 in-lbs). Follow torque sequence shown in Figure 1.
