10. REMOVING SHAFT FROM OUTPUT

ASSEMBLY.

To remove the output shaft from the cover it will

be necessary to use an arbor press and

push from the back side of the shaft using

caution not to damage the parts.

Fig. 4 Pressing out shaft.

11. REMOVAL OF BEARINGS.

A. Use a wheel puller to remove the cone

portion of bearing from the shaft.

B. Removal of the upper bearing cup from the

output cover will require light tapping on the

backside of the cup with a round aluminum

bar and a hammer working around the

perimeter as you tap to prevent binding.

Continue this procedure until the cup is free

of the cover.

C. Removal of the lower output bearing cup

from the output cover requires prying from

the backside or drilling and tapping of jack

screw holes or the use of a pulley puller.

12. INPUT SHAFT REMOVAL.

NOTE: The output shaft must be removed prior to

input shaft removal

A. Rotate the input shaft and inspect all parts

for damage. Endplay in the output shaft is

not permissaable.

B. Remove all input bearing cartridge

capscrews.

C. Tap on the end of the input shaft to drive the

opposite cartridge from the housing. Then

drive the shaft in the opposite direction for

removal of other cartridges.

NOTE: Keep shims with their respective cartridges

you will be asked to reinstall or replace with the

same shim thickness during assembly.

D. Remove the input shaft/cam assembly

through the large cartridge hole (does not

apply to 662RA see Step E).

E. The 662RA requires removal of the cam

locknuts while still in the housing and

pressing the shaft through the hole

previously occupied by the input cartridge

and removed in Step C. This will

automatically remove the bearing cone from

one end of the input shaft. The use of an

arbor press is recommended but this

procedure can be accomplished by driving

the shaft through with a soft faced hammer.

F. Remove cam through the output opening.

cones from the input shaft.

B. Using a spanner wrench remove the cam

locknuts.

C. Remove the spacers from the shaft.

D. Use an arbor press to remove cam from

shaft, using caution not to damage parts.
