How Do I Change Gears On A Torsen Differential?
The following information is direct from Ward Bowerman of Zexel Torsen The first Torsen units manufactured for SLP used a two piece “paddle” or thrust block as we call it. Later in production, we switched to a one piece block which was acceptable for all 3.42 and lower numeric axle ratios. During assembly of the axle, the thrust block must be removed for insertion of C-Clips which retain the axle shafts. The distance from the face of our ring gear flange to the thrust block is 35.8 millimeters. The height of the ring gear for the 3.42 ratio is 34.7 mm allowing removal of the thrust block past the highest point of the ring gear. We are not aware of the height of ring gears for 3.73, 4.10 and 4.56 ratios. Obviously, the ring gear becomes higher as the numeric ratio increases, and for the highest ratios, the one piece thrust block will not pass by the ring gear. To allow for these higher ratios, I believe SLP has the two piece block available for sale. At assembly, the block half farthest
