M60 non power steering belt set-up

[slum dog]

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.

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.

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

Mine ended up being a bad tensioner assembly. I replaced the tensioner and I have no more noise.

There are couple of different size pulleys available for M60, as well as two different length belts in the first place...

Easy to mix them all up :)

Just cant get this belt on, how did you get it on, and have you been running with this set up?

ive now ordered 7pk1400 should be better i guess?!?

and yes, i have replaced the big one, so now there are two small pulleys.

Can you post a picture of how far off it is?

I've been running this setup for about 1000 miles. No slipping or noise so far. Belt went on fairly easy too.

I tried this belt and it slips with the tensioner all the way tight. I am grabbing the next size shorter and I will see what happens. I will update with my results

Looks like the Honda Accord 03-04 also have this 7pk1388 belt.

it was almost impossible to find that length at auto parts stores, its from an element but thats an element without AC, you can get it at grainger for almost $60 or you can get a bando one off amazon for $15

[dirty30]

Remember to use two of the smaller pulleys instead of the large/ small factory setup.

I checked up on it, found out that these models have this belt.

Honda Stream, Suzuki Grand Vitara and Renault Espace

Maybe also the model you mentioned, but it probably just have different name here in europe.


Thanks for posting this thread, now i can do my e30 non power steering.

Hello.

From what model does the 7k 1388 belt come from? Any bmw?

Thanks!!

Its a belt I had to order from a local autoparts store. I *think* it is used on a Honda Element. I just called up my buddy and had him look for the 7PK 1388 without searching a specific year/ model.
