I cant for the life of me figure out how to loosen the crankcase pulley bolt.I took the four surrounding bolts off now the 19 mm has me baffled,what can I use as leverage to not have the pulley turn when I crank the breaker bar on the center bolt?

Sorry forgot to mention model of truck.95 pickup 4x4 v-6,3.0

I put mine in 5th gear and parking brake (most turns of the wheels per turn of the crank). If you have an auto I think park locks it up. You shouldn't have to remove the other 4 small bolts. They just hold one of the pulleys to the front for an accesory belt.

I wedge a breaker bar against the frame and bump the starter. Then the bolt will come off by hand.

use the "tap the starter" trick or see my build thread (THREAD B in my sig) to see what I did.

leverage is your friend, 4 foot cheater pipe, 1/2'' drive breaker bar, 1/2'' drive air socket....then chock the wheels, put it in gear (assuming it's a stick) and you should be good to go. (lefty loosie)

getting it back on to the 1 zillion foot / lbs it needs is even more fun.

put those 4 bolts back in. you're gonna lose them and you don't need them off.

This method works really well, but it is kind of dangerous.

Im in the tail end of head gasket replacement,got the heads and camshafts on yesterday.was gonna put the intake and phlenum on yesterday also but decided to wait till I got the timing belt replaced so started working on the pulley bolt,gave up after ten minutes of frustration.Will the "tap the starter" technique work in the half state of rebuild Im at?Dont want to %@#& things up now.And knowing I can put those four bolts back on can I use them somehow to bolt something onto the pulley as leverage?

Roofmaster

Cant I cut out the old timing belt and cut the new one in half,thread it through then have my wife sew it back together?Dohh

If you do a search, you will come up with dozens of shop-made tools to help you with this. (I, of course, am partial to this one: https://www.yotatech.com/forums/f116...h-3vze-137934/) I agree with kfarrar: lots of people claim to have used the starter method, but it just sounds too dangerous to me.

More importantly, you're going to have to put that bolt back in at 181 ft-lbs, and the starter method won't help you then. So you NEED a tool, you ought to just make one now and save yourself a lot of work.

Oh yeah,automatic tranny.

92 TOY

great....you're screwed.

Hey 92 Toy you solved my riddle thanx,I read youre rebuild post and got to the part where you broke the extension cord(laugh) then you used webbing.Im a tree climber as well as roofer and have hundreds of lengths of that webbing I use it in the tree for all sorts of stuff including supporting my body,and its rated for like 2600 pound breaking strength,as soon as it stops raining Im going out to do it that way,let you know how it works.I know it will,thanx again.Why didnt I think of that?

92 TOY

you need to use some sort of non-skid to keep it from sliding across the pulley. and for that extra OOPMH put a long wrench between 2 pieces of it and give it a twist (like a boy-scout tourniquet). I show that method when I put the bolt back on.


good luck.

leaving now to do some running around, check on ya later.

Holy Cow! Where did you find a "book" that actually advised using a chain wrench!! Does it show how to adjust valves .... with a 5lb sledge hammer?

TrikeKid

Nothing wrong with a chain wrench provided you know how to use it. They're my go to for removing subaru crank bolts since my impact wrench doesn't like to turn corners.

So I wrapped the nylon webbing around the pulley clockwise pinching it in half until it was around one and a half revolutions,then wrapped a couple more wraps so the webbing actually would get tighter as it was cranked,then I secured the other end of webbing to passengers side frame,mistake,so wrapped several times around drivers side frame,put breaker bar on with 5 foot pipe and walla,success thanx all,especially 92 Toy.

92 TOY

YAY me.!!

good deal. now get to work.

92 TOY

ahahahaha....Haynes.

Thanx 92 Toy,got pulley off timing cover,replaced timing belt put pulley back on,reversed webbing torqued crankpulley bolt.Got intake on,fuel injector rails,metal fuel hoses to injector rails,valve cover gaskets,rear timing covers,cam gears,and alternator.Whats left is air intake,power steering pump,air filter hoses,and all those friggin vacuum hoses,oh but before all that I have to set the timing.Anyone got any secrets?
