Re: Bits of brass in a 32 900 differential
Posted by 32model901 On 2011/4/14 19:18:45
Some additional pictures of the bearings used in the differential.
Correction - the pinion rear bearing is a double row ball, not a single row.
Note - the brass cages have dis-colored because they have been attacked by the old gear oil that had sulfur in it, to give it EP properties. Over the years moisture combined with the sulfur to form sulfuric acid, which attacked the brass.
