how to turn rotor (cap and rotor) to remove screw? - Honda Prelude Forum

bb2'95 · 07-20-2002, 10:38 PM

im trying to replace the cap and rotor on my car and noticed that when i took the cap off, the rotor is turned opposite the direction that i need it to be in order to remove the screw holding it in. I suppose i could just keep puttin the cap back on and starting the car until the rotor happens to stop where i want it to, but thats a pain. Will jacking the car up, putting it in 5th and turning the front wheels rotate the rotor to where i need it to be? thanks

take a 19 mm long socket and put it on the crankshaft pulley bolt, and rotate it counterclockwise until its to the point. Or take a long flathead screwdriver and put tape on the end and insert it in the timing mark window between the tranny and the block, and carefully rotate the flywheel with the screwdriver prying it around. it also would be alot easier if the sparkplugs were out to reduce the force needed to rotate the crankshaft. but not necessary.

Or you could just crank the engine with the key quickly so it turns alittle bit at a time, just have someone watch for the screw.

Best thing to do is use the 19mm and turn the crank

man.. i got it to the right place, but that screw is on there freakin tight. i dont want to strip it since that sounds like something that happens commonly. im gonna take it in to a shop i guess..

take off the distributor, rotate, then take it off by hand.

i had to take it to a car shop to get the screw off
they used a "special" screw driver to get it off
and they charged me $5

It's called: Impact screw driver.

A must have for DIYers

I'm not too sure it's safe to use the impact driver on the distributor rotor. It looks fragile (plastic). A good fitting screw driver should work just fine.

Hes right.

A impact screwdriver reqires about 20 ft lb or more of force to compress it and turn it.

I can't get that screw off either, I just left it on there, guess I should get that rotor changed though, who know the last itme it was done.

Persevere! I just leaned onto the screwdriver with all the weight I could put on it, slowly turned it, and managed to crack the screw loose.
Too bad I didn't know about the 19mm socket wrench for turning the crankshaft. I actually put the cap on, cranked it with the key, and took it off quite a few times to get the screw positioned right. Ugh.

I hope you ment 20lbs. There is not real way to hit something with torque.
