HVT VALVE ASSEMBLY TEST/REPAIR/REPLACE .
This task covers:
Multimeter (Item 12, Appendix B)
Oil pressure gauge (Item 43, Appendix B)
General Safety Instructions
Well ventilated area for testing and cleaning
Tool kit, general mechanic's (Item 1, Appendix B)
Dry cleaning solvent (Item 30, Appendix C)
Install pressure gauge in oil manifold or in oil supply line attached to oil manifold. The minimum gauge capacity
