TM 5-4210-233-14&P-1
5-39. STEERING GEAR-Continued
NOTE
You will have 41 or 42 rolls to assemble into the side
cover bearing; 41 rolls - BR-970; 42 rolls - BR-970-1.
Do not mix these rolls for the side cover with the rolls
for the trunnion cover side of the gear housing.
(32)
If the side cover does not have a caged bearing assembly, assemble 41 or 42 rolls into the side
cover bearing race. Grease must retain rolls.
CAUTION
Doing steps (33, 34, and 35) with a sector shaft that does not
pass the "thumb nail test," and a replacement seal (20) that does
not have the Teflon washer (21) integral to it can result in the
seal being destroyed when assembling sector shaft into side
cover.
NOTE
If the service replacement Teflon backup washer (21) is not an
integral part of the service replacement seal (20), ex- amine the
lead in chamfer or radius on the side cover (short) end of sector
shaft (2) bearing diameter. If rough edges can be felt by drawing
a thumb nail across the lead in chamfer or radius on the end of
sector shaft, go to step (36).
CAUTION
• Be sure that a separate Teflon washer (21) is not used with a
two piece seal (20/21) that has the Teflon washer integral to it.
• The words "oil side" must be visible on the seal after it is in
place. If not, the seal will not function, and a loss of power
steering assist may occur.
(33)
Assemble the steel back up washer (22) into side cover (15). Assemble a new Teflon washer (21)
then a new two piece seal (20), or a new two piece seal that has the integral Teflon washer (20/21)
into the side cover, such that the words "Oilside” are visible after the seal is assembled.
(34)
Assemble retaining ring (19) into the ring groove in the side cover.
CAUTION
Be sure that one or more bearing rolls do not become dislodged
during assembly of sector shaft into side cover.
(35)
Apply a generous amount of clean high temperature grease (Item 15, Appendix E) to the short
bearing area of the sector shaft (2), and insert the sector shaft into the side cover (15). Screw the
adjusting screw into the side cover until it reaches solid height. Then, back out the adjusting screw
one turn, so that the side cover rotates freely on the sector shaft.
