...the good news, is that I have a spare pulley for the front of the jackshaft, the bad news is I need a rear pulley (the accessory drive side). Can someone help me with the diameter of the rear pulley ? It sits on a 15/16" (24mm) shaft, this part I know...
For the record, the front pulley has a 20mm bore, is 150mm diameter, and has a ~34mm outside diameter hub that extends 10mm past the rear face of the pulley...

thanks again--Lee

Lee, 8MA1244 is a late and one that was finished in Germany. FWIW the rear pulley is a triple sheave. The diameter of the largest pulley is 5 3/8 inches measured at the belt pitch (outer edge). The pulley actually has a slightly larger OD.

Oh, I hate it when I do that (!)  Which pulley is broken, and how badly?   Right before I sent off my piece with a chunk missing to have duplicated by JK Pulley, big brother suggested Harley the brilliant welder at ACD and now I have a genuinely round original. I had a NOS front pulley someone bought thru Ebay ~9 years ago, but wherever there may be a spare has still escaped.

(and PS, after breaking the cast yoke on the clutch linkage while removing the tired clutch master cylinder on 8ma1046, I was super, super careful when doing the same thing on 8ma1076...and well, broke that too. At least, second time making a steel bracket was easier !).

M!ke, yeah, I think that is where big brother took the first one If by chance, its just the single-sheave front pulley---you may have luck with something generic and modified for shaft Diameter. for the 3 sheave pulley, mine was completely lost and Hall had this one...Harley built up/turned it.

  The earlier (maybe even your car) had 3 sheaves of nearly equal diameter, and then the Alternator drive (final sheave) grew in diameter...

That's the one...  Luckily my chip(s) aren't as bad as the one in your pic...  and on mine it's the unused sheave (since I don't have the smog pump).

Will post progress pics when I get her at repaired...
