INSTALLATION
| 1. | See Figure 1. Install the oil cooler (2) to the frame with two down tube clamps (4), socket head screws (3) and nuts (5) from the kit. Do not tighten hardware at this time. | |||||||||||
| 2. | See Figure 1. Secure the oil cooler (2) to the frame mounting bracket using socket head cap screw (1), two washers and a nut from the kit. Ensure the mounting tab of the oil cooler locates to the rear of the mounting bracket of the frame. | |||||||||||
| 3. | Tighten the three oil cooler mounting screws to 3.4 N·m (30 in-lbs). | |||||||||||
| 4. | See Figure 2. Remove the spin-on oil filter and oil filter adapter (1) from oil filter mount location. Clean the oil filter mounting area thoroughly. Discard oil filter and adapter. NOTE The oil cooler adapter assembly has a flange protruding out of the back side. The flange must be installed toward the oil filter mounting location and through the oil adapter gasket. | |||||||||||
| 5. | See Figure 3. From the kit, install the oil cooler adapter gasket (3) onto the oil cooler adapter assembly (1).The oil cooler adapter assembly flange should be aligned so it is installed into the oil adapter cooler gasket cutout as shown. NOTE Due to the locating flanges, the oil cooler adapter assembly and gasket will only install properly in one position on the oil filter mounting surface. | |||||||||||
| 6. | See Figure 3. Install the oil cooler adapter assembly and gasket onto the oil filter mounting surface of the engine with the mounting fitting (2). Ensure adapter locates properly in the mounting surface. Ensure the raised lip of the mounting fitting faces the adapter assembly. Tighten mounting fitting to 16.3–21.7 N·m (12–16 ft-lbs). NOTE Slide hose clamps from the kit onto the hoses prior to installation. |

| 7. | See Figure 4. Obtain the cooler bottom hose (5) and cooler top hose (6) from kit. Follow the markings on hoses to connect onto the oil cooler and oil cooler adapter, as shown. | |||||||||||
| 8. | Fasten hoses to oil cooler adapter and oil cooler with worm drive clamps (4). Tighten clamps to 0.9 N·m (8 in-lbs). | |||||||||||
| 9. | Lubricate a new oil filter's seal with new engine oil. Thread filter on until seal touches mounting surface, then turn an additional 1/2 to 3/4 turn. NOTE Position the clamps to avoid interference with oil-filter installation. Check that hose routing is clear of the oil filter and sharp edges. The hoses must be free of bends or kinks that could obstruct oil flow. | |||||||||||
| 10. | Ensure all cables and harnesses are clear of the oil cooler adapter, in order to prevent wear. |
System Flow Test
NOTICE
Oil level cannot be accurately measured on a cold engine. For pre-ride inspection, with motorcycle leaning on jiffy stand on level ground, oil should register on dipstick between arrows when engine is cold. Do not add oil to bring the level to the FULL mark on a COLD engine. (00185a)
NOTICE
Oil level cannot be accurately measured on a cold engine. For pre-ride inspection with the motorcycle upright (not leaning on jiffy stand) on level ground, the oil should register approximately at the midpoint of the cross-hatch area on the dipstick when the engine is cold. Do not add oil to bring the level to the full mark on a cold engine. (00186b)
NOTICE
Do not operate the engine when the oil level is below the add mark on the dipstick at operating temperature. Engine damage will result. (00187b)
| 1. | Start engine. Examine all hose connections for leaks. If there is no leakage, allow engine to warm up. NOTE Position the clamps to avoid interference with oil filter installation. Check that hose routing is clear of the oil filter and sharp edges. The hoses must be free of bends or kinks that could obstruct oil flow. | |
| 2. | Verify that temperature of oil cooler increases when engine reaches normal operating temperatures. If the oil cooler remains cool after engine has warmed up, there may be an oil obstruction. Turn off engine and check system for source of obstruction. | |
| 3. | After engine has cooled, re-tighten all hose clamps to 0.9 N·m (8 in-lbs). | |
| 4. | Fill oil to FILL level on dipstick. |
