Must make an emergency belt change. Is it possible to rip/cut away the B230 lower plastic belt cover and change the belt without removing the crank pulley? Seems like I remember changing a B21 belt without removing the pulley.

Thanks for your answers. Got hold of a correct pulley holding tool and an
extra long Harbor Freight breaker bar. It went fairly well. Did have a scare on the first test start. I had removed the front spark plug to make sure of TDC, but forgot to replace it. Ran kind of rough.

"I had removed the front spark plug to make sure of TDC, but forgot to replace it."

I did this same thing, except the reason I removed the plug was to use the rope to hold the crank. I was on the street, replacing a harmonic balancer which had come apart on my MIL's 940 12 years ago, and I'll never forget that startling popcorn sound of the motor running with an open hole.

Thought for the day: Never be afraid to try something new. Remember that a lone amateur built the Ark. A large group of professionals built the Titanic.

Wow never seen that before!

I agree with you Dave.

A man can have separations issues but that one, is the real deal!

Yeah boy I know that feeling!

It's the kind that makes your shoulders jump up towards the your head.
I think there is a switch at the base of the neck to catch that reflex!

You know, the one that turns the light on in the head. The light brightens considerably when it hits on the idea in there.

Oh Crap, I forgot to......! That's when wives notice the eyebrows twitch upward too! When you are looking around under the hood.

Thanks for posting back with your progress!

The 200 series column has been slowing down with good stories and questions. (:-(

Not to wish any repairs upon ride but keep your post coming, as it's cheap entertainment for many!

No, Amarin is correct it cannot be done.

The shield he is talking about is made of cast aluminum and the lower plastic cover utilizes it.

I believe you are also correct about the B21. In a way as is on that engine.

As I remember it's that way on my '78 does because it does not have the heavy harmonic balancer.

It comes with a split pulley that you have to undo in order to get the belts off going to the A/C compressor. It's mounted solid to the engine block within a bracket.


You can change the belt on the road if you have a way to lock up the engine. Without an air impact you have to loosen the with a long, long wrench. Enough to break the torque of that bolt, of which is up in the neighborhood of 120 or + foot pounds.

I have a three foot long 300 lb. torque wrench but I have never used to check what the 60 + degrees equates to. I have tried to torque the engine once by setting the parking brakes while in gear and the engine creaks around on me.
If I use the impact with air pressure at or above 120 PSI in spins it right up to spec. It's a whole bunch of, a lot easier!

You can put the bolt in as tight as you can get it, "temporarily," with a standard torque wrench or a breaker bar and a cheater but don't leave it that way!

But Now, if you have an automatic transmission....you will be needing to locking up the engine or at least be grappling with the turning crank pulley.

A Vise-Grip chain wrench will work in a pinch! (:)
That tool is cheaper than a tow truck unless you have AAA for other reasons, like for a wife's piece of mind!
Just so happens this insurance worked out for me about six weeks ago. I had a "first time" timing belt break while running around four miles from home with her in the car.

It's reasonable priced as we only cover her and she has to be in the car!

As good as I look, I'll bet it won't change the "name" rules!

Hi Phil,

It looks like you are looking for conversation. Yes the RWD forum here is awfully slow and so many people post and never mop up afterward like joe did.

OK here, you said:

"If I use the impact with air pressure at or above 120 PSI in spins it right up to spec. It's a whole bunch of, a lot easier!"

I say, "Oh yeah? Tell me about it."

:)

The problem with "the tool" is you don't have one when you need one.

You have to remove the flange to get the belt on the sprocket. You have to remove the crank pulley to remove the flange.

Its not possible because the crank pulley is so close to the front lower timing cover. Removal of crank pulley is a must. Needless to say you can break it (timing cover and all) and install the new covers later as you've said its an emergency. But you still need to negotiate the belt past the shield around the crank timing gear. Never tried this way before so I can't comment on its success.

See the FAQ for the rope trick or borrow a crank pulley holder tool.

Amarin.
