Ring gear play on carrier

[sunday86]

Hi, as i say in my presentation, i am in the long process of the rebuild of an old DAX Tojeiro which has many parts common to jaguar E-Type. According to my research my dif is a 61-63 E-Type powerlock dif. This dif has a 3.54 ratio and i want a 3.07 ratio (Here in France, sourcing another dif with good ratio or find a "good" jag rebuild shop is not easy at all). As i work in mecanics and have a mecanical workshop at home i decided to do the stuff myself.

My diff was mounted in 3.54 so 3.07 is in the same case / diff carrier height range. I've ordered a Dana44 motive gear ring and pinion knowing that the "minimal" stuff will be shouldered 7/16>3/8 bolts and new input flange (not a concern as new driveshaft to made).

All fits but i note that ring gear has 0.0015" of lateral play on the carrier pilot. Dana 44 carrier ring centering pilot is 5"5625 to 5"5640 (Auburn diff information). My Salisbury carrier pilot diameter was precisely measured to 5"563 with a micrometer so is in range of the Dana 44 spec (see pic in my gallery).

In normal situation the ring is mounted tight on the carrier (which was the case of the old 3.54 ring) so i am wondering if some of you have same experience with Dana 44 gear on a Salisbury powerlock carrier or do you think it's a bad gear ?


Thanks for reading, have a good day.
