So I whipped off my wheel and had a listen, and found the tensioner that tensions the supercharger and waterpump was noisy.
I scoured all the stores in Masterton (and even resorted to repco

I thought I could just put a new bearing in it, but I don't know how it could press apart from looking at it, my ae82 just had a circlip and then the bearing pressed in it, but this looks like a sealed unit.
Does anybody know if I can take in apart, or where I can get one?
Are they the same as 20v ones?
Or if they came on any other engines?
I checked my bluetop 4age and they are different.
Thanks
