Hi all, 1995 525i 5SPD 284k
I'm trying to remove the tensioner pulley and I'm using a torx 50 bit and it's on there very tight but, I'm afraid I will strip the bolt. Am I using the right torx size?
Thanks in advance.
8mm Allen on mine.
all mine are 13 mm hex bolts
Thanks! I haven't tried an allen. The torx 50 fit ok but, had a little play and that bolt is on tight.
It depends... Your best bet is to take a look with an inspection mirror. Mine had an allen originally, but it seems new ones only come as torx, don’t remember if 50 or 55.
I think you might be trying to remove the pulley from the tensioner which does not have a replacement available. Two M8 bolts w 13mm heads hold the tensioner to the OFH.
If you can leave two black stripes from the exit of one corner to the braking zone of the next, you have enough horsepower. - Mark Donohue
One is, one isn't. I forget if the hyd or mech one is replaceable.
I see to remember removing a torx screw on one that turned out to be the "isn't" one.
I can dig through some of my old parts later and see if I can refresh my memory.
Meanwhile I suggest you look into if a replacement pulley only is available. I had thought I'd found the replacement for this once and it/I was wrong.
Sorry to be so nebulous but memory is foggy

Hydraulic one is definitely replaceable; I know zilch about the mech one, though...
Just looked some of my old stuff. Yours is the mechanical type which means you are SOL for finding the pulley alone.
You can buy the entire tensioner 11 28 1 735 899 $15 Dorman(china) @ Rock Auto to $45 for OE INA @ Amazon
Supposedly #s ending 748 832 & 427 252 are exchangeable, I only searched one #, might be worth sniffing around using all the #s for better price

hydraulic is not an upgrade IMO, just different.
