Gilamonster Veteran Date registered: Sep 2013 Location: New Mexico Vehicle(s): G #1 (mix of a 460, 461 & 463), #2 is a 2000 G500 Posts: 151 | Hub bore diameter Are there any hub bore diameter differences amongst the various years/models of the G Wagen? The reason I ask is that the military wheel manufacturer, Hutchinson, specs at least two different hub bore diameters for the G. One is 84mm and another is 84.6. Any info/knowledge/detail is much appreciated. William | ||

There's alot of good info on that site. He lists it as 84.1mm. So why would one of the Hutchinson GWagen options be 84.6? | ||

G-wagenaccessories Date registered: Feb 2008 Location: Vehicle(s): Mercedes-Benz | RE: Hub bore diameter Here is the word from Hutchinson, in regard to the hub bore diam. on the WA-1207 and WA-0492: Hello Karl, It is not a misprint. The WA-1207 is approximately ½ millimeter larger. (Both will fit the G Wagon). The ½ millimeter difference won’t mean much. The ball seat bolts will center the wheel on the hub. | ||

William William, I am not a mechanical engineer, but I'll offer some ideas for you to explore, or maybe some of our more engineer types can speak up. Factory G-Wheels are hub centric. My guess is that when it comes to handling the significant vertical loads that a wheel has to handle, hub centric is a good thing. Of course the lugs are there keep it hub centric while they handle the additional loads related to turning, etc Technically, the Hutchisons are lug centric because their hub bore diameter is larger than the hub diameter. I don't know that a .5mm total difference in diameter is significant. Maybe? Maybe not? Hutchisons were the supplied option to the Marine Corps IFAVs. Others have used them too with no reported issues related to the hub vs lug centrics. Edited by J.R. 3/25/2015 7:33 PM | ||

I picked mine up at the factory and got a tour. They were testing run flat tire, imitate get shot by a 50ca,l then it had to go 100miles at 50mph, pretty neet Attachments ---------------- hutchs WA-0492_Spec.pdf (196KB - 10 downloads) Hutchys WA-1207+Spec.pdf (347KB - 8 downloads) | ||

The hub bore diameters have been machined to the specifications?dimensions, there are nor "inserts" to be found.

I know this is a bit of an old thread but it has very important info even today. As I understand it the Hutchinson have a .5 mm difference from rim to hub on the G500. Anyone know what factory rims would have for tolerances to compare it too? Is this normal or is it usually much smaller closer tolerances. I have a bit of a shimmy on the front end of my G500 which I was told is due to the rims being ever so slightly bigger than factory, only happens at some speeds comes and goes, not normally an issue and I understand the tread helps aggravate things. So how does this .5 mm compare to normal Benz wheels? Is shimmy normal with these rims - tire combos? Also has anyone spent the time - money improving on the tolerances? Thanks | ||

Hence the conical seats on the lug bolts. So, in my opinion, that .5mm should make no difference. With that being said, my Hutchies wobble like crazy and I am in the process of trying to figure out the best method of balancing them. The beads didn't work for s@@t. I have clip on weights now and are better, but I am going to have a different shop try stick on weight next (the problem is they need to be placed carefully as to be clear of the tight clearance of the brake calipers). | ||

Otiswesty Administrator Date registered: Jun 2007 Location: Portland, Oregon Vehicle(s): 463.241, 461.213 Posts: 3004 | Re: Hub bore diameter The best way to get rid of the wobble is to machine the center bore and press fit an adapter ring so that the center bore is correct. The local hutchy dealer in Portland is doing this now. Every one I know that has run these wheels ended up either selling the car or the wheels before too long.... | ||

burqueDOKA Elite Veteran Date registered: Jul 2006 Location: Albuquerque, NM Vehicle(s): 1550L37Doka, 404 ROCKMOG, '00 G500 Posts: 622 | Re: Hub bore diameter I just had my Hutchinsons rebalanced for the third time (first with beads, second with clip on weights). This time I found a local shop that had low profile (thin) stick on style weights that would clear the front calipers on the G500. I am happy to say 98% of the wobble is gone! There is just a touch in a very small window of around 45-50, but very minimal. Otherwise she is smooth as silk, for the first time in a couple years. I think these wheels really need their weight placed close to the face of the wheel, so you really need to use the stick on style. I suppose the .5mm difference could have an effect, but I am very skeptical about that theory causing issues, again, these are nut-centric wheels not hub-centric. There is more unbalance going on with all the detachable parts that have their own balance points be put together in one mass. All beadlock wheels will be a challenge to balance. An other thing to keep in mind is air pressure. To hard much air will exacerbate the feel of minor wobble. I would be curious to hear what real results the Hutchinson guy in OR. is having with his procedure. Edited by burqueDOKA 10/3/2017 2:59 PM | ||
