longjohn Posted April 14, 2020 Share Posted April 14, 2020 I had both of mine replaced on the ‘05 at the dealer at around 50k. It wasn’t cheap. Link to comment

Used throttle bodies from E-Bay is a big crap shoot with a large number having cracks, you can try Bing USA as they will install new plastic cams or full cams/shafts but (personally) I'm not enthused with how they re-time the base idle screw settings. You can buy the parts from Bing USA cams-on-new-shafts, then install them yourself but that is a bit fiddly with some basic mechanical knowledge involved. Here is a write up that I did a while back on installing the cams/shafts yourself with re-setting the base idle screws. https://www.bmwsporttouring.com/topic/92006-posted-to-see-how-a-tb-shaft-install-how-to-reads-in-a-full-thread/ Link to comment

Evening vhntr1 Here are the shafts with cams already installed__ (link below) Your screws should be re-usable, same with the clips if you have the proper tool to remove them, the cap is a bit difficult to remove so maybe buy a new cap just in case (all the caps I have removed have all been removable without damage but it can be a bit tricky). Probably don't need plastic bushings but yours might be worn a little. http://bingcarburetor.com/store/p134/Type_77_Throttle_Body_Pulley_%26_Shaft_Assembly.html Link to comment

vhntr1 Posted April 15, 2020 Author Share Posted April 15, 2020 Take all the plastic off a light and a mirror and you can see them very easily,go to utube and look up max bmw they have a video that shows you how to remove the plastic. Link to comment

Making me want to remove my tupperware to have a look. Any special cover to remove or should this cracked area be visually accessible once plastic is off? Morning Bigfish The ones that I have installed looked to be exactly the same as the originals. I haven't seen any of the replacements break but none that I have installed have many years on them yet. Once you get access to the throttle bodies you need to slide the plastic covers (the covers that cover the throttle body cams) up the throttle cables to uncover the throttle cams, then use a small mirror & strong light to view the throttle cams. There are mold lines on the plastic cams so don't confuse those with cracks. Link to comment
Bigfish Posted April 15, 2020 Share Posted April 15, 2020 Great pic DR. I will check mine soon. Thanks for the description... that helps greatly. My bike almost has 30,000 so fingers crossed. Link to comment

My bike almost has 30,000 so fingers crossed. Afternoon Bigfish Nothing confirmed but from my past experiences it seems to be more of a time period & number of engine heating & cooling cycles than actual miles traveled. I did a 2009 1200rt last fall that only had 13,000 miles on it. On side with a little crack & the other side with 2 large cracks. Link to comment

(very easy to damage the clamps if wrong tool is used) If you try to pry or use the incorrect tool there is great chance that you will distort the clamps or bend the clamp retention area tits then you end up with loose or leaking clamps, or worse they snap open while riding. Be very careful in removing the throttle cables so you don't break the cable adjuster barrels at TB bracket. Your can leave the TB boots connected to the cyl heads & air box then pull/work the TB's out of the rubber boots & off the bike. When re-installing the TB's don't forget to install the plastic covers on the throttle cables BEFORE installing the cables into the throttle bodies. Above all-- if something doesn't seem right or feel right then STOP & understand why that is happening before proceeding. Link to comment
vhntr1 Posted April 17, 2020 Author Share Posted April 17, 2020 Thanks DR I was wondering about the small silver clip that is by the throttle cable? Link to comment

Morning vhntr1 Nothing special or extreme, sometimes the cable will just pull out of the clip with a little tug & on others you need use a small screwdriver to reach in & deflect the clip a little. Just don't force it (be gentle), use common sense. Don't forget to remove the throttle cable from the TB cam before pulling the cable out (you can rotate the big TB cam against the spring in the open direction then work the cable barrel out of the hole with the cable coming out through the cam slot.

You can usually buy or even rent or borrow CV joint earless boot clamp pliers from a local auto parts store as those low profile boot clamp pliers are used on automotive front wheel drive low profile axle boot clamps.
