tweetyduck Posted March 22, 2010 Share Posted March 22, 2010 this is the most dumbass question ever. Whats the part code for the belt that goes with my new Alternator? Might as well change it for a new one. Should i change the tensioner as well and if so whats the part code for that? Quote Link to comment Share on other sites More sharing options...

tweetyduck Posted March 23, 2010 Author Share Posted March 23, 2010 I'm gonna ask this here and also in the defender forum. The 100A alternator has a smaller wheel on it. Should i go with the one fitted and go for the shorter belt or should i swap the wheels and use the same belt as per the old setup. The belt on the old one was a 1595 and i have both lengths of belt (i.e 1595 and 1580). My thinking is the unit is designed for the smaller wheel so use the one fitted as manufactured and use a shorter belt. I'm presuming the shorted belt is designed for the smaller wheel???

western Posted March 23, 2010 Share Posted March 23, 2010 use the pulley as on the original alternator, thats all I did on my 100amp. longer belt is probablt for the air cond fitted vehicles. Quote Link to comment Share on other sites More sharing options...
