I'm getting tools together for a Timing belt change for my 1.5 engine. THe crank bolt looks bigger than any size socket I have, so I;d like to know exactly what to buy. If anybody can remember exactly what socket size it takes, I'd really appreciate you passing that along.

its a 17mm on my 91 crx si

 

Wow, I had no idea it was that small. Thanks for the info.

 

yup - 17mm

The axle nuts are the "big" ones.

 

SOHC crank bolt is 17mm
axle nuts- 32mm
most bolts for the engine are 10-12-14-17....well most of the entire car is made up of these sizes

 

what you should do is bring it to a shop, have them zip off the bolt and then put it back on, its a bitch to take off for the first time...

 

I talked to a shop about doing that, and they suggested I put a breaker bar jammed up againt the frame and use the starter to break the bolt loose. Has anybody ever done that? I heard something about honda engines running backwards, and this trick wouldn't work on hondas.

hehehe. I wouldn't suggest that. I've seen crank bolts siezed on so badly a 650 ft/lbs 1/2'' imact couldn't break them free. Hell my craftsman 1/2 breaker bar is twisted because of one. I know for a fact the starter will not break it free. My first swap the engine sat in the weather guessing for a long time, because the cylinders had rusted up. The starter wouldn't turn over at all. Had to use a breaker bar on the crank to free it up.

 

19mm on b16.. 500ft lb impact for about 2 minutes broke it loose.
