STEP 3
Go to TILT/TRIM RELAY TEST on p. 104 to
determine if problem is power supply.
STEP 4
Remove trim motor and check condition of drive
coupling. If coupling is damaged, replace it.
STEP 5
Temporarily install a known good pump manifold
assembly and retest. If symptoms remain, original
assembly is not the problem. Reinstall original
assembly.
If symptoms disappear, the original pump mani-
fold assembly was faulty. Remove temporary
assembly and replace it with correct one.
STEP 6
Install replacement pump manifold assembly and
retest. If all symptoms are not corrected, recon-
sider the problem using the new symptoms.
STEP 7
Install O-ring kit. Look for any cylinder damage.
Look for chips in fluid or impact valves. Look for
other abnormal conditions. If all symptoms are not
corrected, reconsider the problem using the new
symptoms.
