suitable hoist, slide motor assembly straight onto drive
shaft (61), twisting motor to engage splines on shaft.

3.

Align bolt holes, with air inlet on motor housing facing up.
Insert capscrews (221) through motor flange into adapter
(71) and tighten to 33-36 ft lb. (45-49 Nm).

4.

Clean mating surfaces of manifold (606) and cover
(607). Apply a thin layer of Loctite

®

 515 to one

mating surface.

b.

Insert capscrews (614) through cover. These are just
guides at this time.

c.

Place cover onto manifold. Ensure bolt holes are
aligned. Clamp cover and manifold together and allow
sealant to cure.

d.

Refer to ‘Thermoplastic Coated Parts Assembly’ to
repair removed coating.
