Crank pulley removal tool


neo1

Recommended Posts

Hi all,

 

Has anyone got a photo they can post of the Crank pulley removal tool (to stop the pulley moving or stressing the crank when cracking the bolt)

 

This would be very helpfull, just need an idea so i can produce one tonight to get my wrecked old pully off and my fresh new one on.

 

Have looked at the posts from before but can't see any photos of the tool.

 

Thanks all :)

yep, to stop it rotating....

 

Sorry i was not that clear.... was in a bit of a rush.

 

I know the manual gearbox and crank can put up with a lot of abuse but is it really a wise idea to undo this bolt by just putting the car in gear with the hand brake on ?

 

 

One person i know that works for T*y**a said just to put the braker bar on the floor and turn the engine over once on the ignition.... he said it works every time :s Hmm, i really think this is not good for the Crank :(

 

Any comments welcome :)

it takes alot more abuse daily

yeah i does work, but like you i dont like the idea of it. i'd use it as a last resort. i got it off reasonably easily with a 6ft scaffold bar.

Lock the TC how?

 

3/4 drive air gun, no need to lock anything up, or remove starter and weld up some sort of angle iron jobbie to lock the flywheel or flex plate teeth. Buy or make something akin to the Toyota tool to lock the pulley via the holes in its hub.

 

there are a couple of other ways on SF that i can't remember or be bothered to search out :) (some involve jamming blocks of wood in there - i'm not condoning any of these methods and i have no experience of using any of them)

Has anyone got a photo of what they use to properly brace the pulley ?

 

I still need to torque it uo correctly :thumbdown

 

I have tried the 1st gear and brakes method and it just wong get the torque wrench to click as there is not enough room with the extension bar on it :violin:

 

Really need to stop the pulley dead with this funny self made tool people go on about.

 

Please just one photo someone !!! :eyebrows:

I'll take a pic of the one I made if you promise not to laugh. :D

It's a very simple Y shaped bit of box section steel. It's not pretty but it works well enough. Cost about £6 from B&Q for the materials.

 

Sweet, that would be good cheers.... Were you bolting into the stock two holes either side of the Key-way or were you drilling into anything :S

 

Just to make sure 'this is the DIY tool people have used / made to hold the Crank and pully in place so at to be able to apply the correct 239 lbs/ft of Torque !

 

Also what colour thread-lock should be used on a bolt this big ?

 

Many thanks.

Dont drill anything!!! Thats what the 2 spare hols are for.

 

locknseal is not required as the rotating engine tightens it....

 

Problem is wading through all the bad ideas...... I would NEVER drill anything, just wanted to know why people did and where they did :tumble:

 

The holes either side of the Key-Way are for a crank pulley extractor to fit (for removing the pullley from the shaft)..... If these two holes are also being used for a brace, would the thin bolts used really be strong enough to cope with that torque setting without bending or sheering ????

 

The Bolt is a clockwise tightening thread and the engine rotates clockwise ...... Doesnt that mean the rotation of the engine will try to UNDO the bolt.... not tighten it ?

 

Just wondering :thanks:

I didn't use any loctite and there wasn't any on either of the two crank pulley's I've removed recently.

 

Here's a snap of the tool I knocked up to hold the pulley still:

Heath Robinson has got nothing on me.

 

 

As you can see it uses the bolt holes in the pulley. I couln't see any other way to do it.

Make sure the tool meets the pulley flush like this otherwise the bolts into the pulley will bend:

and also that the box section spans across the recessed hole in the pulley

face. This also helps the tool to stay flat against the pulley.

Supurb.... I will lash one up tonight :ecstatic:

 

What type / size bolts did you use ?

 

Just wondering about the thread etc.....

 

 

Thank you for your help Jake

 

Just one of those moments where you are sure you know what people are going on about but without a picture you have a few doubts.

 

 

Let me know about the bolt sizes

 

 

Cheers :respekt:

IIRC they are M8 x 1.25, not 100% sure on that but they are whatever thread fits the crank pulley. I just found a bolt that was the right thread to fit the pulley and went out and bought a load of nuts and bolts with that thread pitch.
