Replacing rubber skid plate mounts?

KnuckC · 11-15-2010, 07:09 AM

Did an end of the season check on the condition of my Touratech skid plate which was installed by the dealer when I bought the bike. Not pleased to find that three of the rubber mounts were sheared off and the fourth 1/2 sheared. Not pleased with the installation or the skid plate itself. It does not protect the pipes.

Does anyone know how to replace the rubber mounts? It appears that the bottom plate of the oil pan has to be removed.

I don't see why. From my reading of the pdf instructions for the fitting of the skid plate the 4 supplied TT bolts are a direct replacement for the OEM bolts which are simply screwed in to a torque of 8NM. My guess is that for replacement bolts you'll have to go back to TT.

It isn' the bolts that are the issue. On my bike (2010) the rubber mounts appear to be mounted directly to the oil pan on the bike. The skid plate, be it Touratech or something else, screw into these four rubber mounts. What has happened is that the rubber, which is about 1" thick x 3/4" wide, has broken in half horizontally so that there is about a 1/2" x 3/4 " piece of rubber still on the oil pan and there is no bolt thread in that portion of the rubber that attaches it to the oil pan.

On your bike, dos the bash plate attach directly to the metal of the oil pan or to rubber mounts?

Regardless of what the RSD does or does not say, the rubber mounts should be screwed into the oil pan just over finger tight to facilitate removal when they shear. Either way, removal of the oil pan won't help, the threads are cast in, there's no access from inside the oil pan.

There's a hex shaped plate the same size as the rubber at both ends of the mount.

Usually a socket on the hex shaped rubber and an impact will spin the broken mounts out. If not, prying with a screw drive in a circular motion always has for me.

The mounts are made to damp and resist impact. Shear forces should be carried through the front bolt.

Some skid plates protect the mounts from sheer better then others.

The BMW metal skid plate resists sheer well and protects the can, wink, wink ;)

Thanks Joel and AlanI.

I just spoke to Touratech. Their design is really poor. I strongly recommend against using their skid plate. Not only does it not offer any protection from the front wheel sending rocks into your pipes but it is also designed to break. Their system uses a rubber mount that is screwed into the oil pan. Rubber makes sense here because bolting a hard plate directly onto the pan can cause damage to the pan from impact. Their design however is the problem. They bolt the rubber mount onto the oil pan and then use a separate screw to attach the bash plate to the rubber mount. The screw goes in about 1/4 inch and is only supported by rubber for the most part. As a result, vibration causes the screw to eventually sheer the rubber in half leaving a very difficult bolt to remove form the pan.

If you ride alot of rocky dirt, DO NOT BUY THE TOURATECH PLATE.

Now I have to figure out how to get the bolts out off the oil pan. Joel do you know the size of the socket?

Joel, don't worry about it. With a little effort and your advice I got them off.

Thanks

Hey KnuckC,

A customer of our posted that he used anti-seize when he re-installed the BMW breakaway skid plate mounts and I think that is a great recommendation! That will end any possible problem/frustration of getting broken mounts out later.

We will be adding that to our instructions.

The mounts are a standard BMW part and available at any BMW dealer.

As I mentioned in another thread we have designed our front bracket to be stronger than most to help support the breakaway mounts and prevent minor impacts from breaking them. It is still however designed to be "sacrificial" and bend in the event of a significant impact thereby protecting the engine block.

More info on the thread here:http://www.advrider.com/forums/showt...536723&page=13

Thanks for your email and interest on the MOD skid plate too and please ask if you have any more questions!

See you out there!

KnuckC · 11-16-2010, 07:03 PM

Hey Dave,

I just picked up your V2 skidplate. Will Locktite work as well as antiseize?

njoytheride · 11-16-2010, 07:47 PM

I had the same issue with the skid plate bolts coming a part. orderd some from McMaster Carr for less then $2.00 per bolt. I have the part # somewhere. <>< Njoytheride

Thanks KnuckC!
I appreciate the support. You're even in the same neck of the woods so I'll definitely see you out there!

I wouldn't use Loctite. You can use a synthetic grease (like a good quality bicycle grease since it won't harm the rubber) in a pinch. Otherwise Canadian Tire down on Main will have anti-seize in the auto section.

I would definitely like a part # if you can dig it up. I hadn't researched it yet and I though they were proprietary.

How about a group buy?

Although I am not sure of the exact thread specs (M8?) on the rubber mounts, I am sure that Mackay Rubber in Melbourne Oz have them. They are a customer of ours and the range of stuff they make is amazing.

Page 1368 of the McMaster Carr catalog has a list of candidates. I don't have the requisite dimensions handy--anyone hanging out in their garage today that would like to chime in?

I tested this link and it got me close, but not to p. 1368: http://www.mcmaster.com/#vibration-d...mounts/=9rcap6

njoytheride · 11-17-2010, 10:18 AM

I'm looking in McMaster Carr catalog # 110, page 1218. part # 9376K122
M8 x 1.25 bolt size. I order several items on this order so not a 100 % sure.
It is called a vibration damping mount. <>< Njoytheride

Bucko · 11-17-2010, 03:33 PM

I don't see that PN doesn't in the on-line catalog I have up (not sure of cat#), but a search says it is a

Natural Rubber Vibration Damping Sandwich Mnt Cylindrical, Male/Male, 3/4" Height, 1" Width

$1.87 Each

When I look up those dimensions and price, I get PN 9376K213, which is a

Natural Rubber Vibration Damping Sandwich Mnt M8 X 1.25 Thrd, Cylindrical, Male/Male, 3/4" H, 1" W

$1.87 Each (also available in Neoprene)

Go figure. Either way, it looks like a mucho cheaper solution than BMW will sell you.

Which one works on the 1150 for the front? is it: http://www.mcmaster.com/#9376k213/=dbdoi2? what about the rears?

Thanks!
