1. Sel Hub ( 1D ) flange side up. Press outbound Bearing Cup of part T-158422 into Hub using ( 1C )
pressing tool.
2. Turn hub over and press inbound Bearing Cup of part T-158422 into hub using ( 1C ) pressing tool.
3. Place inbound Bearing Cone of part ( 1C ), into Bearing Cup of part ( 1C ).
4. Grease Seal ( 1B ) lip and press seal inlo Hub ( 1D ) using appropriate tool until seal is flush with end
of hub.
5. Place Hub ( 1D ) into pressing base. Press 9 Studs ( 1H ) into Hub.
N.B.-:-U

6. Sel Spindle assembly ( 1A ) on special fixture with the flange down. Don't set unit on Coupling ( 7 ).
Turn Hub ( 1D ) over and lower onto Spindle ( 5 ).
7. Install oulbound Bearing Cone of part ( 1C ) into Bearing Cup, position ( A ).
8. Apply Loctite 272 on Bearing Nut ( 1F ) thread. Screw Nut ( 1F ) on top of Bearing Cone of
part ( 1C ). Leave .003-.005 inches endplay to check the inilial rolling torque with the unit tied down
to the bench. Then torque Bearing Nut ( 1F ) until rolling torque is 40 to 50 in-lbs greater than initial
rolling torque. Using tool T-206569 for the Bearing Nut.

9. Using appropriale tool install 2 Set Screws ( 1G ) into Bearing Nut ( 1F ) threaded holes. Make sure
Set Screw is driven into the spindle thread. Tighten the set screws to damage the thread and stake
the edge of Ihe nut around the Set Screws ( 1G ) so the nut will not loosen.
10. Insert input Shaft ( 9 ) into mesh with Coupling ( 7 ) intemal splines.
11. Place Thrust Washer ( 4H ) into counterbore of Spindle ( 1A ).
12. Place Planel Gear Subassembly ( 4 ) into Spindle ( 1A ) through gap between 2 Studs ( 1H ). Align
the planet gear bore with one of the planet shaft holes on the spindle ( 1A ) assembly using T-209919.
13. Insert a Planet Shaft ( 4E ) into the planet shaft hole described in Step ( 11 ) on Spindle ( 1A ). The
end of the planet shaft that does NOT have the roll pin hole should be inserted into the Spindle FIRST.
14. Now insert Planet Shaft ( 4E ) through the first set of Thrust Washers ( 4B ), Planet gear, then the sec-
ond set of Washers ( 4B ). Use an alignment punch or similar tool to align roll pin holes on
Spindle ( 1A ) and Planet Shaft ( 4E ).

( 4G ).
15. Drive Roll Pin ( 4G ) down into the aligned roll pin holes. Pin should be flush with ODof spindle.
16. Repeat Steps ( 11 - 14) ) for the installation of the 2 remaining Planet Gears ( 4F ).
