Differential Thrust Washer Gage Installation

Callout	Component Name
1	Front Differential Carrier Assembly Tip Install the differential assembly and the pinion gear assembly together to avoid interference with the gears during installation.
2	Front Differential Drive Pinion (w/Transfer Gear) Gear Assembly Tip Install the differential assembly and the pinion gear assembly together to avoid interference with the gears during installation.
3	Front Differential Drive Pinion Gear Bearing Cup Tip After placing the bearing cup on the gear, place DT 47800-2 which is part of DT-47800 selection gage kit , onto the bearing cup. Special Tools DT-47800 Thrust Washer Selection Gage Kit For equivalent regional tools, refer to Special Tools.
4	Front Differential Carrier Bearing Cup Tip After placing the bearing cup on the gear, place DT 47800-1 which is part of DT-47800 selection gage kit , onto the bearing cup. Special Tools DT-47800 Thrust Washer Selection Gage Kit For equivalent regional tools, refer to Special Tools.
5	Torque Converter Housing Outer Seal
6	Torque Converter and Support and A/Trans Fluid Pump Housing Assembly Tip Install 2 DT 47800-6 which is part of DT-47800 selection gage kit , into a case threaded hole at approximately 180 degrees apart. Tip Some alignment of DT 47800-1 and 2 which is part of DT-47800 selection gage kit , may be required while lowering the TC housing onto the case. Install DT 47800-3 which is part of DT-47800 selection gage kit , spacer over DT 47800-6.

1	Spacer Bolt M8 x 127 (Qty: 8) Caution: Refer to Fastener Caution in the Preface section. Procedure Install the remaining spacers evenly at every other bolt hole. Remove the DT 47800-6 which is part of DT-47800 selection gage kit , guide pins and install spacer bolts in all bolt holes at spacer locations. Tighten the bolts in sequence to: Tighten 30 N·m (22 lb ft) Special Tools DT-47800 Thrust Washer Selection Gage Kit For equivalent regional tools, refer to Special Tools.
2	Front Differential Carrier Assembly Caution: If the bearings are not properly seated into the bearing cups, the washer selection will be inaccurate and the bearing pre-load will be set too low. Low bearing pre-load will cause premature failure of the front differential drive pinion gear. Rotate the differential assembly 10 revolutions to allow the bearings to seat into the cups. Tip Differential rotating tool DT-47793 differential rotating tool can be used to rotate the differential from the case side.

Component Name

Caution: Improper thrust washer selection can cause insufficient taper bearing pre-load which will cause premature failure of the front differential drive pinion gear.

Front Differential Bearing Washer

Tip
Place DT 47800-7 in the gap in DT 47800-2 which are both part of DT-47800 selection gage kit , to determine the proper thrust washer. Choose the correct thrust washer. Refer to Taper Bearing Preload Selective Specifications.

Tip

•	Continue trying different sizes of DT 47800-7 which is part of DT-47800 selection gage kit , until the gage will no longer fit into the gap. The correct thrust washer size is equal to the largest blade gage that fits into the gap.

•	Match the size of the correct DT 47800-7 blade which is part of DT-47800 selection gage kit , to the color code in the thrust washer specification chart. The washer color coding is on the outside diameter of the washer.

•

The gap in DT 47800-2 which are both part of DT-47800 selection gage kit may not be even. Hold the top of the gage and rotate the bottom of the gage to even out the gap. Take two gap measurements 180 degrees apart. Average the two measurements and select the thrust washer that is closest to the average.

•	The washer color coding is on the outside diameter of the washer.
