4.7 REPLACING SHOCKMOUNTS
The engine and generator use different style shock-
mounts and hold down hardware.
4.7.1Replacement Criteria
When the neoprene shockmount has been cut, split,
abraded or has flared due to wear from bolts and normal
deterioration.
4.7.2Shockmount Replacement
a. Engine
1. Remove the two 1/2---13 x 3---1/4 inch long
capscrews. (Loctite has been applied to these bolts.)
Place sling or other device under engine (near oil
reservoir) and slowly raise the engine enough to remove
the engine mounting shockmounts. (The fan may have to
be rotated to prevent striking the fan shroud.)
2. Install shockmounts and flat washers as shown in
Figure 4---13.
3. Apply Loctite EV (purple in color) to threads of
bolts.
4. Lower engine, secure, and torque shockmount
bolts to a torque value of 45
¦
2 ft---lb (6.2---0.2 mkg).
b. Generator
1. Battery w/box must be removed along with discon-
necting the ground strap and moving the control box
aside for clear access to the generator’s shockmounts.
2. Follow the procedure for removing engine shock-
mounts (steps 1 thru 4) as it would apply to the generator.

MAINTENANCE OF PAINTED SURFACES
The unit is protected by a special paint system against
the corrosive atmosphere in which it normally operates.
However, should the paint system be damaged, the base
metal can corrode. In order to protect the unit from the
highly corrosive sea atmosphere or if the protective paint
system is scratched or damaged:
1. Clean area to bare metal using a wire brush, emery
paper or equivalent cleaning method.
2. Immediately following cleaning, spray or brush on
a zinc rich primer.
3. After the primer has dried, spray or brush on finish
coat of paint to match original unit color.
