Okay, I’m starting my rear end “switcheroo”…I’m mating the ends of a Salisbury (tube) differential housing to a banjo differential housing….that way, I can use the stronger late axles with their superior bearing & hub…..plus, I can change out the rear gears easier & quicker…..& I have the lightness gain by switching from the heavier Salisbury tube differential housing to the lighter banjo housing.
So, today I disassembled both rear ends & marked where I think I need to make my cuts for welding…I’m planning on cutting the ends off the tube axle leaving about 1” of the tube on the bearing ends…then, I’m going to turn down that tube so I can slide a steel blank (with the same I.D. as the O.D. of the banjo differential tube) over it for welding…..then, I’ll slide that tube over the outside of the banjo rear end (after cutting it off just behind the hub end (I‘m using a banjo wire wheel differential housing that will be widened to steel wheel dimensions)…..I should then be able to insert the Salisbury tube axles into the banjo differential, ensuring that they seat properly in the gears…..then its just a matter of welding that steel blank to the banjo differential housing tube & the Salisbury differential axle end.
I hope that makes sense so you guys can confirm it’ll work.
In the ‘chunk’ itself (actually, I‘m going to build 3 chunks as explained in a moment), I’m going to remove the pinion gear & pin and weld the differential (spyder) gears solid….I‘ve several sets of those differential (spyder) gears that match the splines on the Salisbury MGB axles so that, in addition to the standard 3.9 MGB gear chunk that mates to the Salisbury axle, using my extra MGB banjo differential (Spyder) gears & the 4.3 MGA gear, & 4.875 Magnette gear chunks that I have, I should be able to modify the extra MGA & Magnette ’chunks’ to fit into the banjo differential and align with the Salisbury axles by using early MGB differential (spyder) gears (welded solid) that match the late Salisbury axle splines.
Does that make sense?
By now, you’ve probably guessed that I’m looking to be able to change the gears in my SCCA car to whatever fit’s the course……….thoughts?
