Manual Tilt System Cleaning and Inspection
1. It is recommended that all O-rings exposed during disassembly be replaced.
2. Clean components, filter, and check valve seats using engine cleaner and compressed
air. Do not use cloth rags.
3. Inspect all machined surfaces for burrs or scoring to assure O-ring longevity.
4. Inspect shock rod. If scraper (located in cap) has failed to keep rod clean, replace
scraper.
Manual Tilt System Reassembly
IMPORTANT: Components must be dirt and lint free. Slightest amount of debris in tilt
system could cause system to malfunction.
Apply Quicksilver Power Trim and Steering Fluid to all O-rings during reassembly. If not
available, use automotive (ATF) automatic transmission fluid.
