LEAK TEST

LEAK TEST
Drain lubricant before testing.
STEP 1
Install lubricant drain/fill plug and seal, thread
pressure test gauge fitting and seal in lubricant
level hole.
Pressurize 3 to 6 psi (21 to 42 kPa).
If pressure gauge indicates leakage, submerge
the gearcase in water to determine source of leak.
If the gearcase pressure gauge does not indicate
leakage, increase pressure to 16 to 18 psi (110 to
124 kPa). Check for leakage.
Make necessary repairs and repeat test.
STEP 2
Complete successful STEP 1 before proceeding.
Install vacuum test gauge. Apply 3 to 5 in. of vac-
uum (76 to 127 mm) Hg. with pump.
Check for leakage.
If leakage occurs, apply oil around suspected
seal. If leak then stops or oil is drawn in, that seal
is defective.
Repeat test. Gearcase must hold minimum of 15
in. (381 mm) Hg.
