The idler gear has ball bearings inserted into plastic and pressed into the gear.  When the tensioner gets weak it allows the chain to 'slap' putting excess pressure on the gear and eventually it disintegrates.  
I don't think the e36 has the gasket shift problem since the pan bolts are external and you could see if they were missing.

Should be okay then. I only took the cover off mine to inspect the chain as it's done 180'000 miles. It's a 1992 E36 and had the original E30 type tensioner. It sounded okay, (M42's were never refined!) but the original chain (which has what looks like Iwis/Jwis markings on the links) has no measurable wear or stretch, the left hand tensioner rail looks good and all three sprockets look good enough to go again. I just happen to have three new ones and a new Jwis chain (in a Febi Bilstein box...) knocking about, so........
I will replace the centre bolt for the extra sprocket (or reverse idler in BMW speak) and put the new bits in - it might do 200'000 miles. Maybe.

i just did this with my project car.. the cam gears are 52$ each... i think the crank gear is 70$. and the damn idler gear is like 125$.. i did not replace the idle gear on my car, but replaced the other 3.. i also replaced all of the plastic guides and the chain tensioner.

There is a picture in my build thread comparing the new cam gears to the old ones.

What's the actual issue with these? Is it the idler gear (the one to the left of and just above the crank gear) or the retaining bolt that fails?
Mine's in bits now. The idler gear is smooth and quiet, very little wear on any of the sprocket teeth at 180'000 miles and the chain looks perfect with no more 'bend' than the new one I have. I have two new cam sprockets and a new crank sprocket. The left hand chain tensioner rail (that the tensioner acts on) looks okay with the usual light grooving from the chain. It has the old type tensioner plunger and I have the later M44 type one to fit.
It's an early E36 so has the different sump. Do these have 'gasket shift'.....whatever that is!?

Cannot find any reliable info anywhere.............someone must know!

This doesn't work either.

Can anyone actually download this manual, or do I really have to go to BMW to find out a simple torque figure???

The Bentley E36 manual is just as useless as the E30 one - it covers the M44 and not the M42.

Engine + Driveline / Tensioner guide bolt torque

« on: October 13, 2010, 03:51:44 AM »

No, it's a small allen bolt part number 0711 991 9941. It looks like it wants around 20nm tops.

Look at parts 11, 12 and 13 on real oem.

Engine + Driveline / Tensioner guide bolt torque

Evening Folks

I'm doing a timing chain replacement on a 318iS, and this is the first one I've done for a long, long time with the older type arrangement with the little guide sprocket at the bottom near the crank as opposed to the later (post 9/93) curved guide 'slipper'.

From distant memory these could give trouble with the bolt snapping off in the block, sprocket loose and chain coming off - an engine write off, basically.
Now, I can get a new bolt and it would be madness not to fit a new one with the front of the engine off. But I cannot find anywhere the correct torque figure and it's something that needs to be right!
I've had a scan through the factory BMW E36 manual but can't find reference to this bolt - it's a 'fillister head' bolt, i.e an allen bolt.

Can anyone help with this please? I'm off to my local dealer tomorrow, but if anyone knows off the top of their heads it would save aggro. Thanks!

Good site btw.
