Part 1 of 2
When installing/assembling needle bearing and bearing race, use the following illustrations as a guide to installation procedures and locations.
1. Install differential lubrication tube and differential gutter to converter housing.
2. Install oil strainer.
3. Install detent spring assembly.
4. Pass parking rod into the hole in the manual plate and then install manual plate on manual shaft.
5. Install band brake servo, retainer and return spring and secure with snap ring.
6. Install reduction gear.
a. Position reduction gear in transmission case so that it meshes with idler gear.
b. Press reduction gear into place using a drift and install idler gear.
7. Install bearing retainer assembly.
a. Install seal rings onto bearing retainer with great care. Clean the grooves and liberally apply petroleum jelly to hold the rings in place. Otherwise, they could be cut or deformed when the low clutch and carrier assembly are installed.
b. Install bearing retainer assembly.
8. Install parking pawl and parking shaft.
9. Install spacer and return spring.
10. Install output gear.
11. Temporarily install side cover and gasket.
12. Lubricate low and reverse brake piston seal, then install piston by tapping it evenly with Tool.
13. Install low and reverse brake retainer, and secure with snap ring.
14. Install low and reverse brake driven & drive plates and retaining plate, then secure with snap ring.
15. After low and reverse brake has been completely assembled, measure clearance between snap ring and retainer plate. If measurement exceeds specifications, it can be adjusted by replacing retainer plate with one of a different thickness.
Low and reverse brake clearance:
Standard
1.2 - 1.6 mm (0.047 - 0.063 in)
Allowable limit
3.0 mm (0.118 In)
- Check low & reverse brake operation using air.
16. Assemble front carrier, rear carrier and low clutch.
17. Install carrier set.
18. Install one-way clutch assembly while rotating front carrier with high clutch hub.
19. Remove high clutch hub, and install clutch snap ring.
20. Assemble reverse clutch and high clutch.
21. Install reverse and high clutch as a pack.
22. Install brake band and anchor pin. Temporarily lighten anchor bolt by hand.
23. Adjust total end play and clutch pack end play as follows:
- Total end play -
a. Remove thrust bearing race from high clutch drum.
b. Install needle bearing on top of oil pump cover.
c. Place Tools (bridge and gauging cylinder) on machined gasket surface of converter housing. Allow gauging cylinder to rest on needle bearing and lock it in place with thumbscrew.
d. Insert Tool (total end play gauging plunger) into gauging cylinder.
e. Place bridge, legs up, onto machined gasket surface of transmission case, allowing gauging plunger to rest on surface where bearing race was removed. Lock plunger in place.
f. Remove bridge and use feeler gauge to measure gap between gauging cylinder and shoulder of gauging plunger.
g. Use your feeler gauge reading to select appropriate bearing race thickness from following chart:
- Clutch pack end play -
a. Place Tools (bridge and gauging cylinder) onto machined gasket surface of transmission case and allow cylinder to rest on high clutch drum. Lock cylinder into place.
- You are now measuring dimension "C".
b. Now, insert Tool (clutch pack gauging plunger) into gauging cylinder.
c. Place bridge, gauging cylinder, and gauging plunger onto machined gasket surface of converter housing. Make sure thrust washer is removed. Lock gauging plunger in place.
d. Use feeler gauge to measure gap between gauging cylinder and shoulder of gauging plunger.
e. Use your feeler gauge measurement and following thrust washer chart to select correct washer thickness to give proper clutch pack end play:
24. Adjust differential side bearing preload as follows:
a. Remove left side bearing inner cone from transmission case.
b. Place Tools (bridge and gauging cylinder) on machined gasket surface of transmission case and allow gauging cylinder to rest on bearing mating surface. Lock gauging cylinder in place.
- You are now measuring dimension "E".
c. Put final drive assembly into converter housing, then put side bearing inner cone on differential case.
d. Hold inner bearing cone in place while spinning final drive assembly in order to seat bearings
e. Insert Tool (differential side bearing gauging plunger) into gauging cylinder.
f. Place bridge, gauging cylinder, and gauging plunger onto machined gasket surface of converter housing and allow gauging plunger to rest on surface of bearing inner cone. Lock plunger in place.
g. Use feeler gauge to measure clearance between gauging cylinder and shoulder of the gauging plunger.
h. Use your feeler gauge reading and following chart to select appropriate side bearing preload shim(s).
i. Install selected shims and left side bearing inner cone.
