INSTALLATION (Continued)

CAUTION

It is of utmost importance that the generator support, cradle, and

U-bolt be installed in a manner that will not disturb generator

mounting alignment and still furnish adequate support to minimize

vibration.

Misalignment of 0.010 inch in any direction is sufficient to

cause a leak (pressure loss) between the generator mounting flange

and the generator mounting adapter. Follow the procedure to assure

alignment and proper support.

6. Loosely assemble cradle (27) to bracket (32) allowing cradle to move freely in elongated

holes.

7. Position the assembled generator cradle (27) and bracket (32) on the oil pan.

a. Secure using four bolts (33) with flat washers (34).

Tighten bolts only until heads engage

washers (finger tight).

b. Install U-bolt (30) over generator and secure using self-locking nut (28) and clamping

bar (29).

c. Tighten two screws (31) securing cradle (27) to support (32).

d. Tighten four screws (33) securing support.
