Adoom Posted September 7, 2015 Share Posted September 7, 2015 So I'm replacing the CA18ET in my Starlet with a CA18DET. The ET uses a single V belt. The DET uses poly-vee/multi rib thing pulleys. I only have the alternator with the single V pulley. Are the poly-vee pulleys pretty standard on nissans? Or are they all sorts of different offsets and diameters?

Frosty Posted September 8, 2015 Share Posted September 8, 2015 Are the poly-vee pulleys pretty standard on nissans? Yes on most post 85 models, a couple of the older engines still in use at the time like the 1200 (A12?) and commercials hung on to the V belts for a while after that date. Or are they all sorts of different offsets and diameters? 1. Diameters? Yes to suit Crank pully size and top RPM of engine. You can get an alternator spinning to fast, you basicly burn them out. 2. Offsets? Not as many as you would think. Tend to get that sorted with the mounting and or spacers on the input shaft. A jump to the newer belts is a good idea more and more the only place you can get V belts is an engineering supply outfit. Just like tubes in tires they are becoming something of a specialty item for vintage, classic and specialised uses. Quote Link to comment Share on other sites More sharing options...
Adoom Posted September 8, 2015 Author Share Posted September 8, 2015 Cheers. I'll have to go to pick a part with the cordless impact gun and my old pulley as a guide. Quote Link to comment Share on other sites More sharing options...
