Replace front frame
 

Hello,
Having to replace the front frame on a R1100s. Are there any special tools required ? How long of a job is this ? Looking to buy a used frame (part # :46512314698). Are there any gotchas we ought to be concerned about ?

Cheers,
John

there is one on ibmwr, also they straighten fairly easily.
no special tools you will need a barrel of tie wraps.
be careful with the headlight they just slide out of the rubber carriers.
also the mirror bolts have rubber o rings that should go back in.

That prt # 46512314698 is for an R1100RT. 46512331387 is for an R1100S. 2cnts from tjs.

Well I certainly don't agree with the above you only have to lean on the front frame and they are an absolute nightmare to get right I had a little blip some years ago and I have never got it right yea sure I can get everything back on with some huffing and puffing but they only have to be a fraction out and their a nightmare.

Anyone who bends a front frame do not take the body work off,attempt to push it straight with the bodywork still on,in actual you don't push it you lean the bike against a wall with the likes of a cushion in between off a the likes of a sofa to soften the impact.

If your buying a second hand one check the history.

Though it was a very minor accident - sliding on black ice - the nib holding the steering column sheered, thus having to replace the whole bloody thing. Everything else is absolutely fine.

Thanks, TJS for confirming the part number. Thanks, Chris. I shall be careful.

Where do you see a front frame listed at the ibmwr site ?

it is in the marketplace, oil head stuff, it was there last night.
well apparently it depends on the straightener,
take it off set it up on a flat bench, clamp the center to the bench elevated on some blocks.
I used a set of straps and a long bar and a conduit bender, to bend it
I used a large framing triangle to measure the attachment points.
bend it until it is "square and the mounting points are where they belong.
then tweak the mirror mountings and instrument mountings until they fit.
took about 4 hours.
absolutely no point in trying to do it on the bike. just use the bike to trial fit it.

I found the complete opposite leave it on the bike bolted up so you can get some leverage(small amount) on it and just tweek it,you move one bit and something else doesn't fit,I'm amazed over the years no one has got a straight one and built a jig,in my case I bought two spares for the next time!!

you risk breaking the mount on the neck,
I tried that but couldn't really bend it without more force than
seemed safe. and easy enough to cut some blocks and do it on
the bench.

Each to his own I guess It doesn't take much to bend e'm and not much more to get them back,but bending the right part is the trick and where!!! because I ended up getting one part back in position and something else wouldn't fit,and hence why I said leave everything on the bike and try and bend it in situ,once all the body work is off the genie really is out of the bottle :(
