And 953 LoadersNew, more complete tolerance specification are available for adjustment of the pinion bearings in final drives of 943 and 953 Loaders. The new tolerances change the adjustment procedure given in the Power Train Disassembly And Assembly section of the Service Manual. On Page 2 - 70 of this Service Manual section, change Step 7 to read as follows:
"7. Check pinion (5) for end play and measure the torque needed to turn the pinion. If the end play is not more than 0.5 mm (.020"), and the torque is 1.1 N m (10 lb in) or less, go to Step 8. If the end play is more than 0.5 mm (.020"), and retainer (7) is tight against the case, it will be necessary to install new parts. If the rotation torque is more than 1.1 N m (10 lb in), install one 8G588 Shim under retainer (7) and check the torque again. Install only one shim at a time, and do not use more than three shims. If the torque is too high with three shims installed, and there is no foreign material under the cups, cones, or retainer, it will be necessary to install new parts."
