INSTALLATION
NOTE
Use Loctite 565 Thread Sealant on all pipe threads.
| 1. | See Figure 1. Assemble oil pressure gauge to mounting bracket using locknuts and retention plate as shown. Tighten locknuts just until bracket studs are flush with nylon inserts in locknuts. Thread female pipe fitting onto end of gauge. Hold square stem of gauge with wrench when tightening female fitting. | |||||||||||||||
| 2. | See Figure 2. Remove oil pressure switch (2) from crankcase and save switch for reassembly. It may be necessary to use a 15/16 inch open end crow foot (Snap-On FC30B) to remove the oil pressure switch. Remove the two rear right hand side rocker box screws (1). Place mounting bracket of oil pressure gauge assembly over holes in rear rocker box and reinstall rocker box screws to hold assembly in place. Tighten screws to 14–19 N·m (10–14 ft-lbs). | |||||||||||||||
