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.
