Hey all,

[’97 Prelude 2.2L VTiR]

Have a question about the crankshaft pulley... I was driving and heard squealing noises, then a loud clunking sound. Pulled over immediately and found the alternator belt had a rip (lengthwise) and the A/C belt had come right off.

Removed the belts and when I tried to turn the engine over there was an immediate (and terrible) clanking sound, so shut it off.

I towed the car home, hoping it was just a belt problem but when I stick my hand down to the crankshaft I can feel that the crankshaft pulley is really loose (I can wobble it back and forth - around 10mm) - which I assume is the source of the clanking noise?

I removed the front RH wheel and had a feel through the access hole to the crank bolt and that wasn’t loose (by hand anyway) so now I don’t know why there is room for the crankshaft pulley to wobble.

The car is due for a replacement timing belt and I’m worried this might have gone Does anyone know if this might be the case (or what else might result in the crankshaft pulley becoming so loose)?

I don’t have the tools (or skill) to replace the pulley myself and I guess I’m trying to decide if it’s even worth towing it to the shop to have it looked at – really suffering cash flow issues here and not sure if I can afford to pay $700+ in labour to have the mechanic tell me the engine is toast...

Any help or suggestions would be greatly appreciated.
Many thanks,
llama

Either the keyway on the pulley got damaged or the keyway on the crankshaft got damaged. I included some pics below to give you a better idea of what I'm talking about. The top is the crankshaft and the bottom is the crank pulley.

Thanks for the pics

I'm clearly not going to be able to get in there to see exactly what the problem is, but assuming it's one of those options, is it easily fixable without a major overhaul of the engine?

It's common for the bolt holding the pulley on to come loose. You may be lucking and that be the only issue. They need to be tq'd to 180 foot lbs


Worse case scenario is you have what happened to bloodshed and may require a new crank....

Those aren't my pics, I just did a quick search on Google for them so he could see what potentially could be wrong.

In bloodSHed's pics he linked, if it is the top picture...unlucky, you'll need a new crankshaft (and I'd replace the pulley as a precaution).

If it is the bottom picture, you are very lucky, and all you'll need is a new pulley and key.

Also, since you are in there, I'd recommend doing the manual tensioner swap, as well.

Thanks for all the help, much appreciated. I think it's going to the shop and I'll let them have a look at it.
