i just replaced a front oil seal in an 85 brat. i locked the flywheel through one of the holes, but the holes are so small i can't get anything substantial enough in them to lock it good enough to get the right torque on the crankshaft puly bolt. i keep breaking whatever i put in there, does anyone have a suggestion of what to put in these holes to lock it up good enough to get at least 40 foot pounds of torque on it?

I spun the flywheel till I saw a bolt, and then I put a box wrench on the bolt, turned it till it hit the housing, and then wailed on the crank pulley bolt. Worked like a charm.

cool i will try that thanks for the tip.

Ive had good luck with a GOOD punch,screwdriver, or allen key in the hole.

thats what i tried at first but i was using a cheapo so i might try a better one. i thought of a screwdriver to but the holes in this flywheel are so small a standard Phillips head screwdriver would not fit in the hole. am i just not looking hard enough? are there bigger holes than the ones i am seeing?

dude...

 

"if your cheater bar is towards the drivers side and long enough to lay on the fender (or anything to stop it I guess)...turn the key for a quick burst of the starter and it'll free the bolt.."

 

stop screwn around and try this..

I wanna see if it works

It sounds like he's trying to tighten the bolt, that only works for cracking it loose.

 

And yes, I've used this method with success.

Although it's probably not your first option if you need to get it off, use something a little more controlled to begin with.

 

 

For tightening I usually just use a good strap wrench on the crank pully. It can hold enough to put a pretty good amount of torque on the bolt.

..glad to hear that method works..thanks 987687..I'd go for it if engine was still in the car

 

this begs the question..what did you (mikaleda) use to lock the flywheel to get your stuck crank pulley bolt off?

I used the bar of a chuck key for my drill press, but a punch is good too.

I'd use an impact gun myself.

 

If you do not have one, a hardened punch is what you want.

Basically anything you try to put through the hole is going to be flimsy enough that it's going to bed while you work on torquing that bolt down.

 

Box wrench on a bolt should work just fine. What's worse with putting something in one of the holes is that it could break and then fall in to the bellhousing. That's not good.

 

Good luck

i used a punch in one of the holes in the flywheel to break loose nut when i tried to torque back down it snapped.

good idea i was worried about stuff breaking off like you said. i like the box wrench idea that should be flexible enough to bend before it breaks and i could really torque on it too.

oh ya 987687 the reason i didn't try the starter to take it off i was worried about damaging stuff if the wrench slipped.0

i did try an impact to get the bolt off initially but it was an electric one and was not powerfull enough

thanks to every one for tips i will post what i use to torque down the crank puly when i am finished

come from the bottom with a big bar and lock it in ring gear agaist the block works well may take two people

Make sure the box end wrench does not loosen the bolt it is on, while you are trying to torque down the crank pulley bolt, especially if you are "wailing (sp)" on the crank pulley bolt.

From HTKYSA.

 

"Step 2. Install Crankshaft Pulley.

Smear oil on the smooth shiny seal surface of the crank pulley. Align the groove inside the pulley with the woodruff key, then slide the pulley onto the crank. Install the pulley bolt and washer and snug them down. Use the socket and ratchet to rotate the crank so you can lock it in position with a punch or phillips screwdriver (Procedure 3, Step 1). Torque the pulley nut to 40 ft. lb., then remove the punch or phillips screwdriver from the timing hole."

 

As indicated in the replies above, push a punch or good round (philips head) screw driver into timing hole. The screw driver is stout enough, and 40 ft-lbs. is not going to bother it.

grammar correction.

box end wrench worked good!

thanks everyone for the tips.
