The force applied to each bolt will be the same. The spanner wrench actually applies torque to the pulley through the bolts. You have to have both bolts attached to get the pivot points (fulcrums) established to apply the torque. It turns out that equal amounts of force are applied to each bolt. I would make the handle as long as possible, but keep in mind you still have to get it to the pulley. On my daughter's car I positioned it from underneath. I did a search for ed c's tool and couldn't find it. Can someone attach a link or picture? Best of luck and continued success! <img src="/forums/images/graemlins/cheers.gif" alt="" />

haven't tried inserting a link here yet, so if it doesn't work, if you enter Ed C in Search's User Name box, you'll get a ton of hits (mostly excellent info). And one of those will be "Crank pulley tool for 3.2 Troop (long)" dated Oct 22 2002. In this post is a link < Crank Pulley Tool > which will take you to some terrific pictures at Webshots. I think the crank holder he designed and built is great, but think it might be easier for me to just do something similar to his, but make it so it just bolts directly to my threaded holes. What do you think? The reason your design sounds a bit more realistic for me is that it seems more do-able with regular tools. thanks again for your help. here goes with the link attempt Ed C Crank Pulley Tool pixIt Works!

Thanks for the link. Kewl tool. Very sophisticated. <img src="/forums/images/graemlins/kewl.gif" alt="" /> I would agree that the spanner tool approach would be easier to make. If you bolted the flat plate (reference the sketch) to the pulley using the two threaded holes I think you'd be in buisness. <img src="/forums/images/graemlins/cheers.gif" alt="" />

Thanks for advice. Just to clarify one of your previous posts: The force applied to each bolt will be the same. The spanner wrench actually applies torque to the pulley through the bolts. You have to have both bolts attached to get the pivot points (fulcrums) established to apply the torque. It turns out that equal amounts of force are applied to each bolt. Do each of the legs (from the pivot point to where it bolts onto the pulley) have to be the "exact" same length in order to have 'equal amounts of force...applied'?. It matters not a wit...?or it matters a little...?or it matters alot...? Just want to feel secure that I'm not going to do some damage to the harmonic balancer and/or it's threaded holes. Thanks again. And also... on Ed C's tool, do you know of a do-it-yourselfer way of creating those half-inch square holes that can accept half-inch drive tools?

Do each of the legs (from the pivot point to where it bolts onto the pulley) have to be the "exact" same length in order to have 'equal amounts of force...applied'?. No difference, really... keep 'em somewhat close for better leverage, but exact dimensions are unnecessary. ... [/b] on Ed C's tool, do you know of a do-it-yourselfer way of creating those half-ionch square holes that can accept half-inch drive tools? There's not an easy way if you lack access to a burly hydraulic punch tool. You could get pretty close with a steady hand and a plasma or oxy-acetylene torch... or you could use a file and get there the hard way, with plenty of time and elbow grease. Randii

thanks Isuzu95 for your crank holder tool suggestion. Please clarify a couple of things:
Why wolmonized lumber? Is it stronger. Do you really think it makes a difference? Or does your Isuzu have termites ? LOL
Seriously, also, I'm unclear about the 2nd piece of lumber you mention. How does it work? (is it matched to length of 'holder piece', so the holder piece is jammed against it on the floor?
I'm afraid on my 92 Trooper, the oil filter/oil cooler assembly would be in the way of the holder piece. Did your application have any interference problems?
Did you try using the tool from above, holding it while torqueing w/other hand, or w/helper?
Thanks for help, and patience in helping me visualize this, before I attempt.

wow! thanks for the picture NATO308. It helps, 'cause I had it visualized totally differently.
Generally, the pipe wrench on the pulley gives me nervous tics, but I can see how'd it'd work, and may give it at least a test.
Did you have any damage to the pulley?

Thanks for help, and patience in helping me visualize this, before I attempt. ............................................................ I suggested the wolmonized lumber because it seems to be stronger. I have made my tool with conventional lumber. I use mending plates on both sides and both ends, so there will be 4 plates on the board that goes on the crank pulley. This piece run horizontally. The 2nd piece of wood runs vertically. It's job is to stop or hold the first piece when you loosen the crank pulley bolt. You place it under the left side of the horizontal piece and it's bottom part rests against the floor Crude scetch follows. ------------- - - - - -

I am not sure what is so complicated about this procedure. 28 replies and the pulley is not off yet?
Ditch the pipe wrench, the special lumber and the general headache.
Rotate the engine so #1 is TDC on the compression stroke, back it off about a 1/4 rotation, feed about 18" if 1/4" cotton rope into the spark plug hole and rotate the crank back up. Trust me, it will lock everything in place well enough to break that bolt free. If it doesn't, use more rope.
Just make sure it is on the compression stroke. I doubt it would cause damage, but having the valves open on the exhaust/intake stroke could prove to be bad. Also, tie something to the free end of the rope to keep it from falling into the cylinder.
Good Luck,
Michael
