WARNING

A hoist must be used to support and lift the assembly when removing it from the

engine. It must be firmly in place before removing the mounting capscrews.

Remove the shaft key (3, FIGURE 3-54).

Attach a suitable hoist to the PTO. Remove the 12 hex-head capscrews (2) that secure the

clutch housing (4) to the engine. Use two pusher screws (3/8-16) in the tapped holes

provided in the clutch housing flange and swing the PTO from the engine.

NOTE

Do not remove the driving ring (1) from the PTO adapter plate unless it is necessary to

replace engine parts.
