  Q: What procedures are necessary for axle shaft removal during a general overhaul of the rear axle on Volvo 245?

  A:

  If axle shaft removal is a part of a general overhaul of the rear axle, all the oil seals should be renewed, which means removing and renewing the taper bearing even if it looks OK. If it is not possible to press off the bearing and the locking ring, the locking ring can be removed by drilling and splitting or drilling with a 1/4 in. (6 mm) drill but being careful not to drill all the way through to the axle shaft. Then remove the inner seal from the axle casing and followed by the removal of the bearing with a press or appropriate extractor and finally the outer seal. Clean the bearing well and give it a final wash in white spirit to remove any old grease and cleaning fluid and inspect it thoroughly for signs of wear or blueing, renewing it if necessary. Reassemble with new oil seals and new bearing if required and even if the old locking ring is intact, it must be renewed. Finally, press or drive on the locking ring, making sure that all the assembly is as close as possible to the shoulder on the axle shaft, and check the oil level.

  Q: What adjustments are made to gear backlash and differential carrier bearing loading in relation to the Axle Shaft on Volvo 245?

  A:

  The rear axle is a conventional hypoid type with the pinion below the center-line of the crownwheel comprising a pinion, crownwheel and differential gear. Gear backlash and differential carrier bearing loading are corrected by shims located in the differential carrier bearings. The differential carrier has two level pinions mounted on a type of trunnion and two side gears that receive the halfshafts via internal splines. The differential gears are made to rotate at different speeds, each gear has a thrust washer beneath it. Taper roller bearings are used for the pinion bearings and the axial position of the pinion in relation to the crownwheel is adjusted with fine-tuning shims located under the outer race of the rear pinion bearing.
