Note: Photos are intended to illustrate the procedure and may
not be consistent with previous assembly steps.
During service of this unit, all O-rings, gaskets and seals must be replaced.
Refer to cleaning and inspection information in this manual prior to assembly.
It is good practice to compare the new parts with those being replaced during
the assembly process (to make sure you don’t mistake the quantity or size).
Flat washers are used under all fasteners where the head of the fastener
contacts an aluminum surface.
Unless otherwise specified, all torque values listed are for capscrews that have
been lubricated on the threads and contact surfaces.
Pipe threads called out as PT (British Standard Pipe Taper) on drawings and
in this text are different from NPT threads. PT threads and NPT threads are
NOT interchangeable. Adapters are available from several manufacturers to
convert PT threads to NPT threads.
Where grease is specified, use a lithium based grease (NLGI 2).
Submerge all new clutch friction plates in clean transmission oil for a minimum
of one hour prior to installation.
This transmission uses liquid sealer in many locations. The approved sealant
is Loctite® 518 (MA1015), applied per S774 (a thin layer of sealant is all that is
required), with Loctite® Primer N (MA1012). Avoid getting sealant into the
O-ring counter bores.
