Torque setting for mounting Ilmberger hugger

[JustAnotherSquid]

Hi all,

Does anyone know what value to torque the Ilmberger/caliper mount bolts to?

TIA,
JAS

I torqued mine the same as the standard brake caliper bolts 30 ft/lbs.

40Nm would be the proper torque for those...

[jclark]

Well RAD, to be more precise, 40.67602287 Lb/ft.
Roughly.

Thanks for the responses all.

There seems to be a problem. Looking from the rear of the bike, the center of the hugger sits about 1/2 - 3/4" to the left of the center of the tire. There appears to be enough clearance on the right side, but it doesn't look "right" at all. I have a 5" wheel and ABS. Is it normal for the hugger to not be centered on the tire?

TIA,
JAS

[jclark]

I've got 5.5"/ABS, and it's purty dern close to centered...can ya take a piktoor?

[JustAnotherSquid]

Ask and ye shall receive.

It's more obvious in person than in this picture, but if you draw a line from the center of the tread to the hugger you can see that it crosses right of center by a significant amount.

I also emailed this pics to Mitch, who forwarded them on to Julius. We haven't heard back yet.

TIA,
JAS

Hey Jeff

40Nm and 40 Lb/Ft, ya can't have both. Ya gotta pick one. If it is 40 Nm then it is about 30 Lb/Ft

[jclark]

Oops!My bad.

Ahem:I meant to say –> 29.5019604 Lb/ft <–

As an old engineering prof once told the class I was in during the introduction of calculators in class( moving from slipsticks) –*"you guys need to be careful about 'plugging and chugging' –*5.528 MAY be the right answer, but if you don't see that it's 5.528 x10-3 instead of 5.258 x10 3, then you are not understanding the problem. You should always know ahead of time , just where the answer you're searching for should approx. be, so that when you get that number, you grok that it's in the right county.

Whew.
I'm better now. Thanks for pointing that out RAD.

Wise man that prof. And if you're doing a "good" engineering design for most applications your safety factor is such that whether its 5.528 or 5.285 or 5.825 as long as the x10^-3 or +3 part is right. :-)

Hey Squid:

Throughout America, many are homeless. Many are starving. Many have serious illnesses and no health insurance. Many dot-com employees are without jobs.

Do you think they care if your Ilmberger hugger is not straight?

Jeez--get a life!

Motoman,

I don't know if the hungry, uninsured, or out-of-work care or not, since I didn't ask any of them.

But since the hugger costs $245, *I* care, as do others who are considering spending their hard-earned money on it.

Personally, this would drive me nuts.
As one who's life has been saved by well functioning gear, I think the importance of paying attention to detail cannot be overstated.

BTW, where did you get your hugger? I'm considering ordering directly from the factory (selling 349 DM).

Hey guys,

Does anyone know if the wheel offsets add up so the 5.0 and 5.5 rims have the same centerline? If not, then the hugger can only be centered for one of them, presumeably the larger. Just a thought.

In any event, it can be shimmed a bit.

One other thing, what's that black soupcan to the upper right in your photograph?

[JustAnotherSquid]

mryan,

I got the hugger from Mitch at Motorsports Imports - the "official" Ilmberger distributor for the US. The "soup can" (as you've so aptly named it ) is a charcoal canister to help meet US emissions requirements. It'll be coming off as soon as I put on a new exhaust. <G>

roger,

That's a very good question. I thought of the same, and measured it. The offset should be ~1/4" if it was designed for the 5.5" rim, no? It's off by about 3X that. If shimming is all that is needed, I'll be a happy camper. What I don't want though is a mis-molded hugger for full price.

Roger,

You hit the nail on the head. Julius said that with a 5" wheel the hugger will be noticeably off-center. Now I have to decide if it's worth $240 to have a hugger that fits so poorly.

Hey, I just put on an Ilmberger and it is pretty close to center with my 5 inch rim at least not so far off that anyone would notice unless they had a tape measure. My problem is when I torque it down to 30 ft pounds the rear brake drags. There does not seem to be any binding with the mounting bracket so can not figure out what is causing the brake to drag. When I take the hugger off and torque down to 30 ft pounds the drag goes away. Help Jeff

I suggest you paint,oil or replace the mounting bolts before you torque them.They rust within 24hrs.

Actually I had to get out the roto-tool to fix the metal part of the fender –*unless there was a relief cut to clear the bolt hole area.
Try moving the brake caliper back & forth, to mark the bracket –*then remove it and radius the area.
Several times.
Once you are able to torque it, and still able to 'float' the caliper, you will be done.
Check after the next ride.
On to the next project!
