(2) Use a dial indicator and measure balancer shaft end play.  New balancer shaft end play is 0.002 to 0.010 inch (0.05 to 0.26 mm). NOTE If end play of balancer shaft exceeds specifications, then check thickness of thrust plate as this determines end play.  Refer to paragraph c. (3) Measure balancer timing gear backlash, as follows: (a) Using a dial indicator, measure backlash between timing gears.  Specifications are given for new parts (refer to Table 5-4). (1) Measure upper balancer shaft gear-to-oil pump gear.  Refer to Table 5-4. (2) Measure lower idler gear-to-lower balancer shaft gear.  Refer to Table 5-4. (b) If backlash is not within specifications, install new timing gears. b. Removal. (1) Remove timing gear cover, refer to paragraph 4.9.2. (2) Remove lower idler gear, refer to paragraph 5.4.2. (3) Remove oil pump gear, refer to paragraph 5.4.9. (4) Measure balancer shaft end play, refer to paragraph a.
