GAUGE GP-COOLANT TEMPERATURE 1706306 - Caterpillar

Adjustment1. Assemble bevel pinion (6) into cage (22) using shims (23) as necessary to get an assembled end play of ... .005 .002 in.(0.13 0.05 mm)2. Install spacer (8), yoke (9), retainer (10), and bolts (14). Tighten bolts (14) to a torque of ... 130 20 lb. ft.(18.0 2.8 mkg)3. Remove bolts (14) and retainer (10). Measure the distance between the end of bevel pinion (6) and the face of the counterbore in yoke (9).4. Install an amount of shims (13) the same thickness as the distance measured in Step 3 less ... .003 .001 in.(0.08 0.03 mm)5. Install retainer (10) and bolts (14). Tighten bolts (14) to a torque of ... 200 20 lb. ft.(27.7 2.8 mkg)6. Assemble the differential in a vertical position with bearing cone (20) and cup (21) at the bottom.7. Make an adjustment to bearing cone (3) and cup (4) by turning adjustment ring (2) to get the maximum preload possible without changing dimension (A) more than ... .005 in.(0.13 mm)8. Use shims (7) as necessary to get the heel ends of bevel gear (11) and bevel pinion (6) in alignment.9. Turn adjustment rings (2) and (19) [the same amount so there will be no change in the preload of bearing cones (3) and (20)] until the amount of free movement (backlash) between bevel gear (11) and bevel pinion (6) is ... .014 .002 in.(0.36 0.05 mm)10. Check the area of tooth contact using the following procedure: a. Put a small amount of Prussian blue, red lead, or paint on the teeth of bevel gear (11).b. Turn bevel pinion (6) in both directions.
ILLUSTRATION Cc. The correct area of tooth contact starts near the inside end of the teeth of bevel gear (11) and goes a maximum of 50 per cent down the length of the teeth. See illustration C for the correct area of tooth contact.
ILLUSTRATION D11. If the area of tooth contact looks like illustration D, use the following procedure: a. Remove some of shims (7) to move the bevel pinion nearer to the bevel gear.b. Do Step 9 again.c. Check the area of tooth contact by doing Step 10 again.
ILLUSTRATION E12. If the area of tooth contact looks like illustration E, use the following procedure: a. Add some of shims (7) to move the bevel pinion farther from the bevel gear.b. Do Step 9 again.c. Check the area of tooth contact by doing Step 10 again. Always make sure the backlash adjustment is correct before making an adjustment to the area of tooth contact. Several adjustments to backlash and tooth contact may be necessary to get the correct adjustments.13. Install pin (15) and cover (18) with no shims. Tighten bolts (17) enough to remove any clearance between the pin and cover.14. Measure the distance between the faces of the cover and the axle housing. Install an amount of shims (16) to get the correct
