The flats on counterweight must align within 1/16 in (2
mm) of the flats on the crankshaft. Use a small metal flat
edge to check. Refer to Dwg. MHP1307.
Counterweight Alignment Check
(Dwg. MHP1307)
CAUTION
• Failure to properly align counterweight on crankshaft may
cause extreme motor vibration, resulting in damage to the
winch motor.
9.
If greater than a 1/16 in (2 mm) difference between the
counterweight and crankshaft flats then the end of the
setscrew should be ground. Grind very small amounts off of
setscrew. Refer to Dwg. MHP1276. Repeat process until
tolerance is met. If this tolerance is exceeded then the
crankshaft will be out of balance, resulting in extreme
motor vibration and possible damage.
Setscrew (218) Adjustment
(Dwg. MHP1276)
10. Tighten the socket head capscrew (216) to 185-195 in lb.
(68-72 Nm), while holding flatwasher (215) centered on
capscrew. Check tightness of setscrew (218).
Cylinder Assembly Installation
Position motor housing back on its side.
1.
Lubricate the inside of cylinders and pistons.
2.
Apply a 1/16 in (2 mm) bead of Loctite
®
515 around the
inboard cap (226) and outboard cap (227). Refer to Dwg.
MHP1297.
Cylinder Cap Sealant Placement
(Dwg. MHP1297)
3.
Place cylinder assembly over piston, push and twist into
position on motor housing.
CAUTION
• Ensure that the inboard and outboard cylinder assemblies
are in the correct position. This is noted by the offset position
of the air inlet holes.
4.
Coat capscrews (229) with anti-seize compound. Insert
capscrews through cap assemblies into motor housing and
tighten to 145-150 in lb. (54-56 Nm).
Motor Cover Installation
1.
Apply a 1/16 in (2 mm) bead of Loctite
®
515 around the
motor cover (223). Refer to Dwg. MHP1318.
2.
Place cover assembly onto motor housing.
3.
Apply Loctite
®
242 to capscrews (224) and insert into
motor housing. Tighten to 40-50 in lb. (4.5-5.7 Nm).
Motor Cover Sealant Placement
(Dwg. MHP1318)
Mounting Motor To Winch
1.
Assemble exhaust manifold (233) by inserting capscrews
(224) through exhaust manifold and into motor housing.
Tighten to 40-50 in lb. (4.5-5.7 Nm).
2.
Wrap a nylon sling around motor housing and, using a
suitable hoist, slide motor assembly straight onto drive
shaft (61), twisting motor to engage splines on shaft.
