Adequate oil pressure activates the oil pressure indicator lamp switch in the filter mount, which turns off the oil pressure indicator lamp.
The check ball in the filter adapter opens at:
- XL Models: 10-13 psi (69-90 kPa) oil pressure.
- XR 1200X: 5-7 psi (34-48 kPa) oil pressure.
Filtered oil leaves the filter, flowing past the check ball.
Disassembly
1. Remove oil filter. See 1.6 ENGINE OIL AND FILTER.
2. See Figure 3-172. Remove oil filter adapter (1) from oil filter mount (2).
3. Remove check ball (3) and spring (4).
Cleaning and inspection
Warning! Compressed air can pierce the skin and flying debris from compressed air could cause serious eye injury. Wear safety glasses when working with compressed air. Never use your hand to check for air leaks or to determine air flow rates.
Thoroughly clean all parts in cleaning solvent. Blow out holes and passages using compressed air.
