I'm getting ready to replace the timing belt and tensioner on my 91 240 this weekend. My only concern is removing the crank pulley. Does it typically require a puller to get it off or do they usually slide off once the bolt is removed? Thanks in advance!!

 

On the 740's I've done in the past, it comes off without a puller, may be a little tap...

 

Thanks Ted, that's what I was hoping for.

I was curious about his, you do not need the crank pulley holding tool and/or air tool?

 

I'm not sure. I'll let you know after I do it and maybe I can pass on some hints for you. I was going to do it this Saturday but I've been working on my car for the last 3 weekends changing all the bushings and shocks front and rear. So I'm feeling like a weekend off would be nice....

 

I have done it without the tool, but it is easier with one. I have a manual trans so I was able to lock it in gear and bump the breaker bar with my hand until it broke free. Line everythig up before you remove the belt.

 

Simply putting it in gear works to unfasten the bolt for the pulley? no problem?

 

You may have to pull the starter so you can lock the flywheel in place but I did not have to. I found someone that had two balancer lock wrenches and bought one for $20, I got lucky. The one at IPD is $48. The way it is made it does not look easy to make one but I may look at this again to see if there is an easy way to make it.

 

I used to have a 740 turbo I did this on. One way to break the crank pulley bolt loose is to use a very long breaker bar and let it rest on the ground and then bump the starter for just a blip of a second. It will work like an air impact wrench. Some say this is a bad idea but I never had any trouble with it. Others chime in.

I'll probably just rent the pulley-holder tool for ten bucks a day.

 

I just did mine, the hardest part was holding the crank pulley to get the bolt off...after that it was cake

 

I went out to change it last Friday, removed the fan and belt cover only to find the belt looked like new. It wasn't cracked, no oil leaking by any of the seals, the tensioner pulley was even shiny. I looked at all of the teeth and couldn't find one crack in the rubber. I think I'm going to ride this one out for a while. If this was an interference engine I would have changed it but seeing as how it isn't, I'm just going to leave it in for a year or so and keep checking it periodically. I couldn't believe there were no leaks at all, I believe someone replaced the belt, tensioner, and seals shortly before I bought the car. Oh well, got a new one just in case. Thanks all for the advice!!
