1986 Mazda B2000 Rack and Pinions Parts and Q&A

• Q: What are the procedures and specifications for adjusting and installing Rack And Pinions in a truck on 1986 Mazda B2000?

  A: The rack and pinions is best removed out of truck and placed in a vise where adjustments can be made. In the case of worm bearing preload, the torque requirements of the wormshaft rotation change by year: 5.2-7.8 in. lbs. between 1979-81, 7.9-10.4 in. lbs. between 1978, 0.9-3.5 in. lbs. between 1972-75. In case corrections are required, take out the end cover and add or remove the shims which come in different sizes. In the case of 1982-86, fit a spring scale to the wormshaft with a required rotating force of 1/2-1lb. and twist with a spanner when needed plus tighten locknut 140 ft. lbs. In 1987-89, the torque is expected to be 3/4-1.3 lb., and the same is adjusted. Clearance in sector shaft, 1982-86, must be 0-0.1mm depending on shims, whereas, 1987-89, shims exist in 0.03mm steps. Backlash is 0 which is adjusted with screw and locknut. To remove and install the rack and pinions, depending on the model year, the following steps are required; removing steering wheel and column covers, disassembling several parts and disbolting the rack and pinions to the frame. Installation is the opposite, and proper torque requirements are used on all connections, rack and pinions-to-frame, pitman arm-to-sector shaft, and others, and special care is taken when handling the front end as well as the suspension parts.
