Do the M116, M117 and M119 use the same tool to remove the guide pins? Does anyone make a tool to reassemble the intake cam adjusters?

Thanks

Yep. Most all 1980's and 1990's engines with guide rail pins use the same type of tools to remove them, either a slide hammer or a threaded puller. You can fabricate something from a washer stack with a long bolt also.


Does anyone make a tool to reassemble the intake cam adjusters?
There is a factory tool, about $125 plus shipping (click here). More info and a photo at this thread.

You can get a cheap but completely adequate pin puller via eBay. It does indeed work with all M103, M104, M116/117, M119, M120 etc engines. I have personally used mine on M104, M117 and M119 engines.

I HIGHLY recommend getting the factory tool for re-assembling the intake cam adjusters, if you disassemble them. It is possible to do this without the tool, but it is an exercise in frustration, and will leave you with very sore hands. I was not successful in reassembling the adjusters until I got the tool, which made exceedingly short work of the job.

You can only get the tool from MB, as the @gsxr says.

Photos of both jobs and both tools being used can be found here:
