WARNING

Use extreme caution when handling heavy parts. Provide adequate support and use assistance during pro-

cedure. Ensure that any lifting device used is in good condition and of suitable load capacity. Keep clear of

heavy parts supported only by lifting device. Failure to follow this warning may result in death or injury to

personnel.

NOTE

Sprocket shaft (5) weighs approximately 185 lb (84 kg).

CAUTION

Use caution and proper handling of equipment and install slowly and carefully to avoid damage to threads

on shaft and in gear case.

Use a suitable lifting device and position sprocket shaft (5) on bevel gear case (8).

Push sprocket shaft (5) into bevel gear case (8) as far as possible using only hand pressure.

Attach hydraulic pump for installation of sprocket shaft (5).

CAUTION

To avoid damage to bevel gear case threads, ensure adapters are installed in bevel gear case so that shoul-

der of adapter is against bevel gear case. After shoulder of adapter comes in contact with bevel gear case,

adapters can be tightened a maximum of 1/8 turn or loosened a maximum of 3/8 turn to put adapter in cor-

rect position so that remainder of tooling can be installed. When remainder of tooling is installed, do not let

weight of tooling or lifting device put a load on adapters. Keep all tooling level.

Install two adapters (12) into large threaded holes in

bevel gear case (8).
