KDeline Posted May 24, 2006 Share Posted May 24, 2006 Both are so tight that I am starting to deform the screwdriver slot and neither has moved a bit. First time I rode all winter long on this bike, I'm sure that has something to do with it. 10,000 miles since they were last moved, 120,000 on bike, R1100RT. Any thoughts, heat, oil, etc? Hope this is not like my tranny drain plug nightmare. Never did get that thing out. Link to comment
Al Navecky Jr Posted May 24, 2006 Share Posted May 24, 2006 Try "PB Blaster" and lwt it sit over night. As alway worked for me. Link to comment
Mulepick Posted May 25, 2006 Share Posted May 25, 2006 PB Blaster's probably the same thing, I just don't know it. I'd use any oil penetrant (which wd40 is not), shoot some around the screws and leave it like previously advised. I like Justice Bro's "80". That stuff works quick! BTW, be prepared to replace the o-rings when they come out. Bob Link to comment
Ken H. Posted May 25, 2006 Share Posted May 25, 2006 Geez Ken, you have the tight issues! Heat is probably a bad idea as it will rather quickly kill the O-ring that's around the LBSs, and leave a real mess in the port if you do get 'em out. Presume we're talking about a situation where they're not tightened fully down on their seats, just stuck in place (1 1/2 turns out or whatever), right? Presuming so, have to tried going IN, just a bit to see if they'll free up? Link to comment

They've gotta be able to take a little heat; afterall, these things will tolerate sitting next to a smokin' hot engine and gearbox when you shut down after a ride. Aluminum does have a slightly higher thermal expansion rate than brass, so heat should open things up just a smidge. Link to comment

I may try a little heat next. Link to comment

big-t Posted May 25, 2006 Share Posted May 25, 2006 Ken,if the soaking and heating does not work, you might try rapping them lightly with a flat tipped punch,lightly being the key word. Link to comment

Any feelings about a impact driver? I would think that would be hard on the brass screws. Link to comment
Reddog900 Posted May 26, 2006 Share Posted May 26, 2006 If the slot is getting worn, place some vlave grinding compound in the slot before you stick your screwdriver in, it will help prevent it from slipping. Good Luck - let us know what works Link to comment
big-t Posted May 26, 2006 Share Posted May 26, 2006 Any feelings about a impact driver? I would think that would be hard on the brass screws. After the heating,soaking and rapping,an impact driver would be my next choice,but be prepared to drill it out because there is a good chance the head will snap off when using the impact driver. (maybe heat the outer housing with a heat gun before trying) I wouldn't hesitate to try it since you will probably end up drilling it out anyway should all the other methods fail. Link to comment
Jerry Johnston Posted May 26, 2006 Share Posted May 26, 2006 Maybe try breaking them loose after you've ridden and the engine is warm? Link to comment
DEF Posted May 26, 2006 Share Posted May 26, 2006 Remove the TBs from the engine, remove all parts from the TBs that can come off and put them in the oven at about 250 F. Handle them with leather gloves (they're hot.......)and apply needed force to remove the LBSs. Then replace the LBSs and O-rings with new. Next, apply anti-seize to the new LBSs and spray the female threads with carb cleaner and blow them clean with compressed air. Install the new LBSs and balance the TBs upon reinstalling.

SANTA Posted May 27, 2006 Share Posted May 27, 2006 sure you can.... but think about all the plastic attached to the TB's, are you sure you want to replace all that stuff plus the injectors etc... just to much chance to do way more damage than necessary... although i have met people who enjoy that sort of thing from time to time Link to comment

If you still have problems, take the bike to Morrie Gauger's old shop in Antioch, IL off Rte 173. The guy there can fix anything on a BMW. Link to comment
Ken H. Posted May 30, 2006 Share Posted May 30, 2006 Hey Ken, did you ever get them loose? Link to comment
KDeline Posted May 31, 2006 Author Share Posted May 31, 2006 No, but not really trying at this point, getting two other bikes ready for a month on the road is keeping me busy. Link to comment
