suejoe6174 Posted September 4, 2012 Share Posted September 4, 2012 looking for a set of rear chrome hub caps for a 1964 B61 single axle tractor ! Quote Link to comment Share on other sites More sharing options...
39 Baby Mack Posted September 4, 2012 Share Posted September 4, 2012 When used on the drive wheels of a "B" model the Mack hubcaps snapped onto an adapter that was machined with a ring in itand fastened onto the wheel on top of the drive axle with longer studs. It also incorporated three "Z" clips that were attached on the drive studs 120 degreesapart from each other. These acted as stops so the cap wouldn't go past the adapter and end up in no mans land.To my knowledge these were only used on drive axles on fire apparatus.Ron Quote Link to comment Share on other sites More sharing options...
