jake_a Posted September 14, 2010 Report Share Posted September 14, 2010 Hi, Can anyone tell me how to identify if a matching crown wheel and pinion set is for a 3.45 diff? How many teeth should each have? Jake Quote Link to post Share on other sites
Alec Pringle Posted September 14, 2010 Report Share Posted September 14, 2010 Hi Jake, divide the number of crown wheel teeth by those of the pinion . . . . . I can't remember the number of teeth on the TR 3.45cwp, but 38/11 or 31/9 for example equate to 3.45. Cheers, Alec Quote Link to post Share on other sites

It is 38/11 which equals 3.4545454545 so I'm guessing that that means it is 3.45!!! Jake Edited September 14, 2010 by jake_a Quote Link to post Share on other sites
Alec Pringle Posted September 14, 2010 Report Share Posted September 14, 2010 Spot on Jake ! And thanks for reminding me of which axle is which. Cheers, Alec Quote Link to post Share on other sites
jake_a Posted September 14, 2010 Author Report Share Posted September 14, 2010 One last question, how do you identify if the pinion is of the collapsible or solid spacer type? Quote Link to post Share on other sites
Mk1PI Posted September 15, 2010 Report Share Posted September 15, 2010 Collapsible type doesn't have a hole drilled for castellated nut and split pin (uses a large nylock(?) type nut instead). Btw collapsible pinion can be machined/drilled to allow setting up with shims if so desired. Quote Link to post Share on other sites
