Alec Pringle Posted January 25, 2016 Report Share Posted January 25, 2016 A couple of odd, as opposed to a pair, of 10" drums that have surfaced . . . . . I'm not familiar with the detail differences between front and rear Lockheed drums and Girling rears, 10" that is, but I'm sure someone here will know better than me ! Any thoughts please chaps ?

BlueTR3A-5EKT Posted January 25, 2016 Report Share Posted January 25, 2016 To my mind... LH one is Girling rear axle TR3/3A - The cut outs in the centre area are for grease emission from overgreased rear hub. The hals n moon slots line up with a drill hole in the hub to the inner bearing area - Stops the hub blowing al its grease into the drum. RH one is Lockheed front or rear Peter W Quote Link to post Share on other sites
Alec Pringle Posted January 25, 2016 Author Report Share Posted January 25, 2016 Thanks Peter, that tallies with my guesswork - I assumed the r/h drum had to be Lockheed, but I can't recall (if I ever knew!!) the difference between front and rear drums.

TR 2100 Posted January 25, 2016 Report Share Posted January 25, 2016 Looks like the round and squared imprints on the drums also gives the game away? AlanR Quote Link to post Share on other sites
Alec Pringle Posted January 25, 2016 Author Report Share Posted January 25, 2016 Hi Alan, yes the square imprint implies Lockheed, it's the difference between front and rear, if any, I was trying to establish . . . . Cheers Alec Quote Link to post Share on other sites
BlueTR3A-5EKT Posted January 25, 2016 Report Share Posted January 25, 2016 On Lockheed I do not think there is any difference front to rear, on Girling I think the 10" rears can be used front or rear on Lockheed braked cars. - Think Alfins here - There are only two diameter flavours - disregard the orientation of the fins. To fit 9" modern Alfins on a TR with Girling axle I believe you have to open out the stud holes to clear the shoulder of the screwed in wheel studs - I would also add the half moon slots to allow the grease to ooze out.
