Worm Drive - Worm Thrust Bearing Lubrication?
Posted: September 12th, 2018, 7:17 am
For the worm drive axle, there was a rear axle housing cap (AA-4190) which had a fitting to allow lubrication of the worm thrust bearing (AA-4696). The cap's initial design had a pipe plug fitting as shown in the attached photo. It was the same as TT-1004. It was used to lubricate the worm thrust bearing.
So, the question is, what lubricant was used? If axle housing lubricant was used, it seems the lubricant would drain down to the axle housing. If chassis grease was used, then how was it applied?
Note that the rear axle housing cap fitting was changed to have a grease fitting about mid 1928. So, chassis grease would have been used at that point.
Anyone have information?
