Thought I would post this here for anyone not running power steering.
Belt: 7PK 1388
Tensioner: Stock M60 drive belt tensioner
Pulleys: Remove larger "idler" and replace with a second tensioner pulley (11281731220 x2)
Belt routing:
You're done!!
Hey guys
Firstly let me say I am no expect on mechanical things ,just learning slowly as I go.....if I never owned an e30 I probably would never been doing what I do now days. That said I was wondering is it possible to run the belt like in my attached picture. I don't understand how these tensioners work all I know it keeps the belt tight in place.
Hope someone will chime in.......
Also I couldn't find a 7k 1388 belt that everyone uses closest I got was a 6k 1390.
Spare shop guy say it will run strong because its a heavy duty dayco belt.
Thanks

Reason: Att. Picture
On my previous M60 I ended up swapping the lower smooth pulley out for a grooved pulley and ran the belt under the pulley, in my mind this allowed the tensioner to apply downward force like original.
However on my recent M62/M60 build I did like yours, belt above smooth pulley and figure I have problems I can change it around later.
OK thanks Mykk I some how never notice your belt setup in your thread, I think I was to busy drooling at your engine build lol amazing stuff there. Will give it a go and see what happens looking at firing the motor up month end, will post back if all goes well.
