So i am doing my 1st timing belt on my 94 and i cant seem to break the 21mm nut loose. The crank is moving when i push the breaker bar and this is with my friend on the breaks and the car in 5th. I have no impact guns or anything so thats out of the question. As i pull the bar it gets harder but still moves. If the crank would stay still i know it would break loose. Any suggestions sorry for the noobness. :fab:

EDIT VVVV


Much to the chagrin of my roommates i did the breaker bar roll over and it worked perfectly lol. Now does anyone have a good video or diagram of putting new belt on and setting the timing step for step?

Wait... You just suggested fitting a tool to the front of the engine and then cranking the engine. Think about it for a minute... Do you actually see anything wrong with what you just said?

Ever heard the expression: "Use the right tool for the job"? I would suggest the right tool for the job is elbow grease and a breaker bar - or an impact gun.

I still can't believe I read this, and that other people agreed!

I almost got my face taken off with a pair of vice grips flying off of an untensioning garage door spring from 15 feet at the speed of ****-what-do-I-do-****-I-cant-move-this-is-going-to-hurt, so I'm usual not all for methods like this.......BUT when you cant get it done any other way, might as well.

Aaahhhh! The only thing I dont like about fishing, is the hook. Despite my like for getting tattoos I hate hate hate needles and sharp pointy things.

Another option...

1. Buy propane torch with a nozzle from local auto parts store.
2. Heat bolt with torch to help loosen/melt Loctite.
3. Impact gun would be best, but once warmed up, try with breaker bar to get bolt out.
4. Personal suggestion: replace bolt since you heated it up as well as the woodruff key.
5. During reinstallation, put bolt in WITHOUT Loctite the first time to ensure God gave you the strength needed to tighten down to spec.
6. If so, remove new bolt, add Loctite, and re-torque down to spec.

What I do in the shop for the miatas is this. Get a chain wrench wrapped around the crank pulley, then put the breaker bar with the socket on it, have someone hold the chain wrench handle while you crank/push on the breaker bar. Yes, the chain wrench will put some small nicks in the dampner, but I have never experienced any problems with the nicks being there. The only thing to watch out for, is if the outer piece of the pulley begins to slip. This means the dampner needs to be replaced.

Whoa thanks for all the repsonses guys, ya ive tried the usual breaker bar with extension and its just turning the pulley. Ill try cranking it over though one of my friends suggested that method just seems a little sketchy. There is no way i can use an impact gun either unless there is some battery operated one. Ill let ya know my progress tomm.
