Ilmberger hugger installation

Bob Hancock · 09-12-2001, 06:27 PM

Hi Guys,
I just received a very slightly used hugger from one of our list buds. It is installed at the caliper but requires slightly longer caliper bolts. Does anyone one know how much longer they need to be and where to get them? Should be an easy fix but I'm a long way from a dealer so can't just pop over.
Thanks.

Pull out an existing bolt and add the thickness of the hugger mount, that should do it. Mine came with the longer bolts but one was made poorly and unusable. I used the stock bolt "for now".

take care

Thanks Dan...guess I was looking for more. Since I didn't get any instructions with it I was hoping for a length and pitch that are already known. (I hope MSC Industrial Supply has a supply of bolts I can order...if not where do you get allen head metric Beemer bolts.) Also, can you torque the bolt to the same value as without the hugger. I can figure it out but it'd be a lot easier if someone would just tell me what the instructions say.
Getting lazy in my old age I guess.

Get the length right!
Too long and it pokes through and touches the surface of the rotor!
Too short and the 40Nm specified torque can strip the thread of the caliper carrier - this happened to me. Had to buy a used caliper to effect a repair.
I don't know the length but do know that it is an M10 thread.

Mark is absolutely right. This same outcome happened to me with too short bolts that were supplied in error with my hugger. Don't know the exact length either but longer high quality bolts are the key. The bolts supplied with the hugger rust very quickly.

Any fastener specialty store should be able to supply you with M10 bolts in stainless steel in just about any length. So as they say pull the stock bolt and add the thickness of the hugger to the length to get your new length.

try m10 x 29mm, I just measured the bolt that came with the hugger.

Please don't!
They must have moved or shut down, the lady at that number is a little tired of getting their calls....

Hi Bob,

I could swear it was M10x1.5x30, but
wouldn't swear to it. I can check tonight
if you'd like. I remember what it was like to live in a smaller town and not be able to find decent hardware. It sucked.

Whatever you do, try and pick one with at least the upper portion of the shaft unthreaded, or ideally, given the fairly thick bracket and caliper mounting boss, get one with only the end threaded. No threads with something loaded almost purely in sheer like this, is important for long term reliability.

If you can't find it at MSC or Grainger and are really stuck, I'll get you some. Hopefully you won't have to resort to that.
I'm reliable, but slow.

later

I'd be willing to bet its actually by 30 mm not 29. 29mm is a rather "unusual" length and I highly doubt Ilmberger is having a screw company custom make the bolt for mounting their part.

Bob Hancock · 09-13-2001, 12:31 PM

Thanks Roger. I just need to pull the bike out and measure the bolt. (It's the Duc's month to be in the garage and the BMW's turn to be out back in the shed.) I looked in the MSC catalog and they don't have it. I plan on driving around town this Saturday and see if I can't drum something up.
Really appreciate the offer to get the bolts...I'll try NOT to take you up on it.
Thanks again,
bob

Bob Hancock · 09-13-2001, 12:50 PM

OK y'all. I got off my lazy butt and went and measured the stock bolt. It's as Roger says...an M10x1.5 and it's 25mm long. The hugger holder is 8mm thick, so I guess a bolt 33mm long would be perfect, but I suspect a 30 or 32 would work just great. That's what I'll go after.
Thanks to all who have provided data.
Bob

Hi Bob
Have just taken one out and their 1.172" or 29.76mm so i can also use a washer on each,and their stainless.

Bob Hancock · 09-13-2001, 01:46 PM

Would you believe....????...I found some of these bolts locally. Bought two 30mm long and two 35mm long. The 35's fit fine and are still about 2.5mm away from the rotor.
Hugger looks way cool. (Thanks Chris.)

okay, little help please!!!

got my Ilmberger hugger in the mail today. went out to fit it and it seems like the arm that bolts to the calipers is just a little off from what the calipers are. to make a long story short, i can't quite get it to fit properly. without hugger, disk brake scrapes brake pads just slightly at one point when spun freely. with hugger fit (as best as i could get it), disk brake scrapes the whole way around....that's not gunna work!

so, any hints to fitting this sucker????

thanks
mike

You sure you installed this right? The hugger bracket goes on the outside of the caliper...it shouldn't change the location of the caliper at all.

morkm · 03-15-2002, 02:13 PM

Yeah, I'm installing it right.....I'm no wrench, that's for sure, but I see how it goes on....

Problem is that the 'arm' on the hugger that has the two 'holes' in it for the screws seems to be a bit off...the holes don't line up perfectly. Now, that's to be expected, but the problem is that as I screw in the longer bolts, the caliper is not getting back to it's 'original,' pre-hugger position as best as I can tell, based upon the amount of scraping the pads are doing on the disk.

So, just wondering if anyone else experienced such a problem and if they've any hints for an idiot

I'll be outside working on this bugger......but checking back to see what wisdom is delt out by the all-powerful list

Thanks
mike

morkm · 03-15-2002, 02:29 PM

okay, it's not going to fit.

I would need to drill out one of the holes a bit to get an extra 2-4mm of space so that all 3 holes (the hugger, the swingarm and the caliper) line up. As it is, they don't line up and no amount of pushing or persuading on my part is going to get them to line up. When i try and force them to line up and get the bolt in, the threads get hung up and it's a no-go. So, any suggestions and/or similar experiences with this hugger?

I guess drilling is going to the the only real option, as the metal on the hugger bracket is a bit heavy to bend and, even if I could bend it, I don't think I could be accurate enough to get it just right. So, now to track down a drill and a bit that will work....grrrrr....I was going to hold off getting a hugger then figured I needed on, so what the heck, I'd shell out the bucks for the good one.

I guess before I drill I'll call Motorsport Imports and see if Mitch has any suggestions and/or will take it back.

Any other suggestions?
Thanks
mike

Carlos is dead on. The caliper doesn't move location one bit with the hugger. Drilling Holes!!! Wow, shouldn't have to do this at all. Pic's would be nice, if only to see the alignment issues your having with the hugger holes to the caliper holes.
