i am trying to remove my starter and do not have a metric allen wrench set to figure out the size i need to go buy.

does anyone know what size allen key goes in those two bolts?

Do yourself a favor. To get any kind of help on this board, you won't get very far without stating what year and model of car you are referring to. Many of us put this in our "signature" part on the user CP.

should be an 10mm. I use a 10mm hex socket.

I have a short piece I cut off with a chop saw, about 1 1/2 in long. I place it in the bolt, then use a box wrench to brake it free. a gear wrench works good once it is loose.
Make sure the bolt is clean so the hex goes in all the way.

thanks charlie!

running to autozone now

not 8mm :/

10mm iirc. Youll want the socket and and 1/2" u joint breaker bar with 1/2" -> 3/8" adapter. Just fits right. The alternative is to drop the rear of the trans and use extensions./

I just ran out in the shop and dug through my bolt supply, and dug through my tool box.

I apologize . It is 10MM.

8mm is the motor mount bolts under the car.

thanks for the help guys

got the 10mm tried to put it in there.... it's obviously the right size but it wont seat far enough down to get a good grip in there. if it were accessible i would bang it in w/ a hammer but with these......

think i am going to wuss out and pay the piper (mechanic)

Do it and spend the money on beer! You can do it, just think smarter not harder! Make sure they are cleaned out first.

Use brake cleaner to clean it out.....do NOT let it slip.

I actually removed one from a 300D NA parts car.....to install on my 1979 300SD (w116). What a pain! I'm glad the w116 had REGULAR hex headed bolts on it.

I saw your year and model. I would read in the archives about exactly how to get those starter bolts. You do require long extensions and a universal.

Up along the transmission from underneath the car is the only way commonly used on your model. You or whoever does it has to use care to not strip the hex in the bolt head. Those bolts can be very tight.



Actually requiring more force to snap loose than a breaker bar can deliver without a good extension on the handle. Three eights extensions to reach the bolt may be too flexiable. Use 1/2 inch stuff. I have no ideal why the top bolt is that tight sometimes. But it is.

[I'd been previously warned] AND an Electric Hammer/Wrench.
