main pulley wobble, sudden.
Heard a noise while driving.drive 20mins til I could get off motor way. Main pulley is wobbling quite noticeably.I'm thinking thrust washer bearing but why would it fail so suddenly.question is it driveable to get home, a 40min drive.

Ok so I think my helper (Yoohoo style belt) was slightly too small and put too much tension on the main pulley. Snapped two of the bolts for the pulley to hub and managed to slot the holes for the other two bolts. So it's new pulley and switch to twin alt. Pulley and belts or Gilmers.

One snapped bolt out then second one I managed to have the easy out snap off into it. Brilliant! Because they appear to be made of adamantium. On a side note, hunting down gilmers now. Does anyone know what the difference between s1-3 rx7 12a and early 13b pulleys and the s4/5s is? I see some Gilmers kits advertised as only for s1-3 FC3s and some advertised as suitable for s1-5 with the waterpump pulley needing milling to 17mm and the main pulley needing one hole slotting.

The water pump pulley holes will be different(shaft size) so that is why you should get the specific kit.
Also the s4/s5 alternator is 15 mm(?) shaft,where the FD is 17mm so that is again different in the kit.
If you do not get the right application then you are modifying it to fit.

s4 water pump snout is 15mm and s5 is 17mm.
the gilmer kit also won't address your borked main hub issue. it also has no timing marks so you need to transpose those to it from the original pulley.
i do sell timing matched hubs/pulleys for $35 plus shipping, but you do need to understand the issues associated with removing the front hub.

I imagine shipping to nz would be spendy but thanks and the issue being slipping torrington bearing and or timing issues?
