crank pulley bolt
 

im doing the belt and wp on my d15y7 engine and i cant get the 17mm bolt off from the pulley. i know theirs a tool to hold the pulley so u can use a big bar and crack it but my pulley doesnt have that. its round inside. i tried air gun and heat and still nothing. im thinkin i have to hold the flywheel somehow? its manual tho. any thoughts? thanks

Take out the starter and get a big flat head screw driver and put it in between one of the teeth of the flywheel so it wont spin. You need someone to hold that while the other person uses the impact gun on the crank pulley. 17mm??? mine is a 19mm but i guess its a different motor. Good luck tho

It should be a 19mm. Also the OEM spec for that bolt is 181ft/lbs of torque. I doubt you could hold the flywheel out with a screwdriver or a pry bar. Best of luck...
What make is the pulley? It should have some sort of holes or cut out to hold it.

I had my motor out and i had a huge flat head, i just put a lot of weight on it while my bro loosened the crank pulley. It worked with a bit of swearing at each other and at the motor. lol

think d series are 17, b's are 19. i broke a few sockets and extensions trying to do mine. impact won't do anything. you need a 3 foot breaker/extension. i used the handle from my big floor jack (it's about 4-5 feet long) overtop of a Snap On breaker bar. there is a crank holding tool for the job. i had a home made one. if you try to hold it by the other end (flywheel side) or try putting it in gear and standing on the brakes (clutch may slip), you risk putting stress fractures in the crank from the torsion and it will eventually crack. that's how people crack their cranks and cams.

theirs little holes around the pulley but their isnt that big female hex nut to put the tool in. and its 17mm.

yeah those holes are to hold the crank. my dad made a spanner wrench type tool to hold it. imagine the letter c with two holes drilled to match the holes on the crank, then a big handle welded to the center of the C. then tap the holes and thread in bolts that will go into the holes in the crank pulley. that's it

On the MR2 we held the crank with a big flat-head screwdriver on the teeth of the flywheel, heated the heck out of the crank bolt and used a breaker bar with a 5-foot steel pipe to get it to crack loose...lol

Lots of fun! :wink:

Did this when i was doing the swap...I did the flat screw driver idea also I put lots of weight onto the flywheel and my dad used the impact gun on max psi and got it out.

try putting the breaker bar on the nut, lower car enough that the floor/ground wont allow the bar to spin, it's a s so point it toward the front of the car, then blip the key on and back off, that should work.

or try using a gun and going back and forth from tight to loose and maybe spray some rust penetrating oil in there and let it sit over night.

That's the last thing I have to undo on my B18C1. I thought the head bolts were hard.... Simply put my dad's just gona bring a big ass leverage bar from work and we are gonna show it who's boss...

well if the heads off but the tranny is still on and the starter, then my method will still work.

Either way GL, let us know.
