320/6 timing belt

[peteferg]

hi all, while the baur resto is under way, and the front panel is off I thought it best to fit a fresh cambelt. ive looked about and there seems to be a few people offerng different belt specs?? 110,111,126 teeth variants. does anyne know what the correct answer is? (1980 320/6)

Remove it and count! 127 with rounded profile is most common. Replace tensioner roller as well and consider a new water pump too when you're there...

Agree but since there are a few versions around... However, if you remove the top timing belt cover you can already see if you have the square or rounded profile. Square is 110-111 and rounded 126-127 and I believe nowadays you can only get 111 and 127 which is fine.

127 with rounded profile is most common.

agreed, i'll eat my hat if its different. same belt as e30 325i too. i know cus the six month old 320/6 belt got swapped on to my e30 325i engine.... im that tight lol.

Glad I didn't offer to eat my hat since I've seen a couple of cars with the 110-111 version which indicates the car didn't have proper dealer maintenance in its first years having missed a modification to the later version, the later belt runs smoother but I haven't seen cases of the 110-111 versions failing so I don't think owners take a big risk if they do not convert.

i dont own a single hat, not even one. technically, i cant eat a hat a haven't got.
