M119 timing chain crimp tool
 

Fellow benz lovers,

I'm getting ready to renew the timing chain on a 1993 400E, it appears to be stretched about 7 degrees after 126K miles.

I pulled out my timing chain crimping tool that I have used several times on OM615, 617 and a 602 Diesel and it would appear that the chain on the M119 is not quite the same dimension as the chains on the diesels. The pins on the M119 chain are about 1mm smaller in diameter than the pins on the Diesel chains.

Since the pins on the gas chain is smaller I'm not sure if I will get a good solid crimp on the master link if I use the tool for the Diesel engines. Has anybody out there done a chain on a M119? Is there a separate thrust piece for the chain crimp tool that is specific to the M119 engines? If so where can I get one?

Maybe I should just use the old "two sledge-hammer" approach for crimping the master link but the crimping tool does a really nice job when it fits correctly.

Thanks - Tim

I think the crimper will work fine. I have used mine on gas engines with no prolblems.

Because of the press type fit, any distortion of the pin will keep the outer piece in place.

Please keep us posted on how the job turns out. I haven't done mine yet and am a little scared of how big a job it sounds like it is on the 119 engine.

If you put the link and plate in place and back up the link with a body dolly or large hammer while carefully peening the pins over the plate with a ball peen hammer, you can get a good crimp without the tool. Feel of the plate to find the smooth side and put it toward the plate. This will give more area to crimp(peen) against.

Good luck,
