26. Planetary Carrier Assembly

1) Inspect planetary carrier assembly for wear and

2) Measure pinion end play clearance (A)with a

feeler gage.

Planetary Carrier Pinion End Play (A)

mm (in)

Standard

0.13 – 0.89 (0.005 – 0.035)

If clearance is outside specified valve, replace
planetary carrier assembly.

3) Install the thrust bearing on the output shaft.

NOTE:

Use petroleum jelly to hold the thrust bearing in
place.

4) Align planetary pinions. Each planetary pinion is

marked with double points to indicate the master
tooth space and exactly opposite with a single
point to indicate the master tooth. The markings
on the planetary carrier consist of double lines
which are to be lined-up with the double points
on two opposite pinions; the single lines are to be
lined-up with the single points on the other two
pinions.

5) After all four pinions are lined-up, slide on third

clutch assembly. Rotate third clutch and check
mark alignment. Considering that the ring gear
tooth between the double points of one planetary
pinion is tooth number 1, count the teeth to check
that the single points on the two adjacent pinions
are between teeth 23 and 24 of the ring gear, and
that the ring gear tooth between the double
points of the opposite pinion is tooth number 46.
If it is not so, remove, realign and try again.

6) Install planetary carrier with third clutch.

NOTE:

Do not force. When properly aligned, the parts will fit
together easily.

7) Remove the third clutch.
8) Install bearing and washer.

NOTE:

Use petroleum jelly to hold the washer and bearing
in place.
