How to remove a crank pulley with no flywheel lock?
How to remove crank pulley without a flywheel lock??
Any good ideas..... I have air tools but was hesitant to try, I was thinking breaker bar instead........ but I still need to hold it from spinning. |

I have used a big screwdriver between the flywheel teeth and braced solid against the bell housing to prevent it from spinning while applying the impact to the crank bolt. Usually takes two people.

I just used eng's method last night on my 16v. You can even do it with the oil pan off. I used a breaker bar.

I used my lug wrent from the trunk, took the cap off the front of the transmission access hole, put the end of the wrench in there and braced it against the crossmember and the crossbar from the side body to the sub frame, this was on an SL, so I don't know if you will have the same points to secure in another car, there is also a tool you can buy where you remove the starter and bolt it in the place of the starter and it locks the flywheel. But it costs $250 and usually has to be special ordered. I have seen some people make a tool that you can hold the balancer at the same time you remove the bolt. Good luck!

I am real nervous sheering off teeth with a pry bar or screwdriver. Does the starter / flywheel lock come from a reasonably priced source? Anyone have one in NY NJ CT?? ... that I may borrow?
Thanks, Ken |

You didn't mention the model, not that it matters because I wouldn't necessarily know the torque spec for any particular crank bolt, but.... A seasoned MB tech once told me that the crank bolts on 126 cars are set around 300 lbs. I've changed many timing belts on asian cars and they all pretty much call for 125 lbs. That's nothing to sneeze at, so when I read about people wedging screwdrivers into metal teeth, then going CC on a bolt set at 300+ lbs., I cringe. I suppose it's been done, but I wouldn't do it. A specific tool, either self-made or purchased would be my choice. My 2 cents. |

Mike,
I did forget to mention, its a 89 300SE W126. At 300 lbs I could pop her free, but thats a lot of stress to a flywheel tooth! Anyone have the lock already? I am willing to pay for shipping if you are not close.... or do you know a cheap source to purchase? |

Ken:
You might try the following: http://www.************************ At one time, they rented special MB tools. Go to their WEB site. I believe they have an 800 number you can use to check into this. |

If it's 300nM, then it would be around 225 ft. lbs. It's my understanding that you multiply the nM value by .75 to get the approximate ft. lbs. Still a sizeable amt. of force to go against. |

I used the flywheel lock tool from my Porsche 928. It fit perfectly on the other side of the engine from the starter on the v8 560. There is a block off plate that you just take off and bolt in the flywheel lock on the bell housing. Takes about two minutes. Get it at www.928international.com Don't use a screw driver. Not sure if it will fit a six cylinder engine though.

I used a large pipe wrench that rest on a piece of 2x4 for removal, the wrench put a dent on the hub behind the vibration damper. For installation, I bought a flywheel lock at my local indy MB parts for $155.
It is a very good tool, it makes the job much easier. Jack |
