Fig. 11 Lower pinion bearing installation. Capri, Fairmont, Mustang & Zephyr
Assemble
1.
Install input shaft oil seal in valve housing. Seal lip must face inside of housing. Ensure seal is bottomed in housing to avoid contact with input
shaft bearing.
2.
Fill input shaft dust seal bore with lubricant DOAZ-19584-A or equivalent, then install dust seal using tool No. T74P-3504-N, or equivalent, Fig.
7.
3.
Lubricate input shaft bearing with power steering fluid, then install bearing in housing using tool No. T74P-3504-P, or equivalent, Fig. 8. The tool
will position the bearing at the proper depth to avoid contact with oil seal.
4.
Install four O-rings in grooves on valve housing, using tool Nos. T74P-3504-G and T71P-19703-C, or equivalent, Fig. 9.
5.
Lubricate thrust washer with power steering fluid, then install thrust washer over input shaft.
6.
Lubricate O-rings and valve assembly with power steering fluid. Insert valve assembly splined end first, into large opening of tool No.
T74P-3504-H, or equivalent, Fig. 10. Position tool and valve assembly over valve housing bore. Push tool and valve assembly into housing until
valve is bottomed and pinion shaft splines pass through dust seal.
7.
Carefully position pinion seal on pinion shaft, then slide seal on shaft until it contacts valve housing. Cupped side of seal must face valve
housing, with seal lip facing away from valve housing.
8.
Install pinion bearing in lower gear housing using tool No. T78P-3504-G, or equivalent, Fig. 11.
9.
Apply lubricant C3AZ-19578-A, ESW-M1C87-A, or equivalent to pinion bushing, pinion bearing and pinion teeth.
10.
Move rack to left stop, then install valve and valve housing assembly into gear housing bore. The flat on input shaft spline must be aligned with
alignment mark placed on valve housing during disassembly.
11.
Install valve housing to gear housing attaching bolts and washers and tighten bolts finger tight. Tighten bolts in rotation one turn at a time until
pinion seal is seated and a torque of 10 to 15 ft. lbs. is obtained.
12.
Install pinion shaft torque adapter T74P-3504-R, or equivalent, on input shaft splines.
