Crank pulley nut size

Ian- 22mm mate.

 

Make sure you buy a socket which would be suited for use on an air impact driver. They are built much more solidly, and are normally matt black in colour rather than chrome vanadium.

 

A regular socket will normally go south at a couple of hundred foot-pounds, let alone 300+...

Cheers, Nathan. I'm going to get an impact driver socket like you say (the black ones). I once had an imperial one that fitted, and I tried taking the crank pulley off the old engine block I had with it. The socket cracked off 1/3 of itself, fired across the garage, and I went south as well, I can tell you...

Hi Rob,

 

99.9pc come undone with an air impact wrench. I've no idea how 'stong' the ones are that the lads downstairs use but they sure look meatier than most I have seen in say Quik-Fit or summat.

 

To say they give a kick when using them is an understatement. Colt 45 springs to mind.

 

As for getting them undone with blowtorches, well, sometimes needs must. If you gotta change your timing belt and all other methods have failed, what are you going to do? Sure, you risk crankseal and pully damper damage but then again snapped timing belt.....

 

I think we've had to do it once or twice from memory, and obviously the customer gets informed of the situation. Thankfully, neither car suffered any after-problems, but then you don't need to heat them up so much that they glow red anyway. It's simply an option when all else fails, and doesn't always result in a problem if done carefully.

 

Those looking to undo the bolt and don't have the tools CAN try the old starter motor trick but a: you won't always get them undone this way and b: as a commercial enterprise we don't think it's ideal to let the customer see and hear an almighty 'thunk' when the extension arm clouts the underside of their motor cos you sure as hell don't want to try holding it...

 

Cheers,

Ah, well I managed to avoid the labour charges after the workshop manager told me they had used a blowtorch but everything was OK, a few weeks later the pulley sheared off.

 

I would have been fine if the guy had said I should pay him to replace the pulley because of the heat damage risk.

 

But that's his learning curve.

Mine was a bit sharp as well, as the pulley fell off mid roundabout.

Indeed. It's criminal that the full facts weren't given to you at the time. Like you say, adding the cost of the crank pully isn't really an issue...

Naaah, .45ACP is a pussycat round, big, fat, and lazy (and fantastic and accurate). .44Mag in a short barreled non-ported revolver with narrow grips sounds more like it :)

 

I'll be using a long old extension (scaffold pole stylee) and some swearing.

Ooops..!

 

Sorry Al- missed your Q ; yes, 'normal' thread ie right hand.

 

Ian: Are you doing this engine out of the car? I sort of get the impression you are. If you are using a long bar, how are you going to lock the engine?

 

BTW, like the firearm description ;)

 

I've only ever been into airguns personally. Odd because my Dad is into shotguns and my brother into rifles! Totally converted to CO2 now- fantastic. Zero recoil and quick-fire action. I usually use a Walther CP88 Competition 8 shot semi-auto with pressure pad laser and Simmons scope. Just bought a Walther PPK 15 shot semi auto gas blow-back though- awesome fun!

 

Cheers,

Engine out? you're having a laugh, mate :) No, the engine stays in. I'm going for dismal trial and error, the usual way I learn these things... If you've got and hints and tips on taking the pulley off without taking the engine out or having air tools, please let me know! It's a 6sp if that helps lock the engine in place...

 

I'm a real handgun fan, love 'em. Used to have a Beretta 92SB and a S&W mod27 with an 8.3/8" barrel. Fired all sorts, from manky Brownings to Desert Eagles, and fell in love with the Sig P220 in .45acp while in Las Vegas this year :) Got lots of video footage of me the Brit humiliating the yanks at their own game :D

 

I've got a Marlin lever action carbine in .357mag which is top fun and my current 'accuracy' gun, and a long barrelled Taurus revolver (which skirts the current handguns ban nicely) also in .357, that's my 'fun' gun. Looking for a Calico next or a straight-pull HK MP5!

 

They ain't stored at home, by the way :)

 

I also have a Sig P220 and Beretta 92f replica gas pistol, plus one of the blowback PPK's you mention - shame the 4.4mm bb's you get don't quite fit it's barrel (it's 4.5mm) so it's accuracy is awful but the fun factor is huge! I want a second one so I can destroy coke cans John Woo stylee :)

 

Trap shooting is fun too, but I don't get to practice it that often.

 

-Ian

 

PS I'm having a proper 4.4mm bore barrel made for my PPK at some point, I'll get a couple done if you want one?

Well, if you are going to use a bar then just jam it against the chassis (be careful of paint damage like I said) and use the starter's torque to indo it. Also- stand clear. You really don't want to catch your finger between the bar and the chassis.

 

As for doing it back up, stick it in 6th and have someone put the footbrake and handbrake on. That should be enough. Hang on the bar if you have to until you reach the well-known torque figure of 'FT'. I doubt if you'll find a torque wrench in Halfords that will do the job...

Why have I got this comical vision of a handgun with a 24" barrel...

I know what you mean about the BB diameter problem. I don't know if you have tried but the lead BB's fit perfect. The steel shot I use (Copperhead) fall through the barrel like you say but in fact I find the steel shot more accurate! Probably the weight difference.

 

Would love to have a barrel to suit the steel BB's though- I didn't know it was possible to change it. Please, let me know if you go ahead.

 

John Woo indeed- don't forget that for tru gangsta stylee you have to have both your arms outstretched, crossed over each other, with the gun butts horizontal..

 

Absolutely useless way of firing a gun with any accuracy of course but the movie watchers love it :)

 

Cheers,

edited to make some sense of this bloo$y VB script thingy..

Useless internet connection here buggered the first reply, so it's the quick and dirty second attempt.

 

Thanks for the advice, and I'm assuming 'FT' is a given value of Tight? :)

 

Taurus is a 12" barrel with a nominal wrist brace, making it 24" overall length. Not as daft looking as it sounds!

 

I've actually been fortunate enough to fire a pair of 9mms (held the right way up, though!), it's mad, glorious fun, but you don't hit a barn door :) Must get that other PPK now... Thanks for reminding me about getting the 4.4mm barrel done, I'll get four knocked up for when you want to go Gangsta as well!

Yes, I think you've got the idea.....;)

So, I was about right then. No chance of you creeping around a corner with that thing....:)

 

Would love to have had a go on that Beretta 92SB!

Ian, how did you get on with getting the crank pulley bolt off m8?

 

I am just gonna have a crack at this, had a little shot using the starter method, but no can do......:banghead:

 

Or anyone with an 'idea' or a 'PROPER' tool to to do this exciting task!

 

Cheers

Suprisingly easy, mate, it wasn't the devils-own job I had been led to believe.

 

Which is a good job as of course, once I had INSTALLED the damn pulley, THEN people gave me all the doom and gloom stories, thanks for waiting guys, and I've heard enough now to be planning the swap back to the stock pulley just for my peace of mind :(

 

Didn't notice much difference in the driving either, just a bit less engine braking and bit nippier in 1st and 2nd at light throttle opening. So, not really worth the stress of waiting for my crank to suddenly snap in half or something.

 

Same goes for lightened flywheels by the way, I wouldn't touch them with a barge pole now. YMMV.

 

If anyone wants to try this pulley for themselves, it's going cheap :)

Guys my 'pulley' seems to be f%*king welded on the bastard!

 

Have just spent past 4 hours trying to get it off.....everything removed, fan shroud, drive belts, lower shroud(air flow) etc...so loads of room and access.....

 

Tried the starter several times, no joy! then put into high gear(manual), handbrake up and wheels well chocked while using 4 foot extension pole 'AFTER' heating the bolt!!!

Still the f*%ker won't move!!!:banghead: :banghead:

 

If I had a can of gasoline I would of given the car a nice wash down and then dry it with the blow torch I was using to heat the bolt!:looney:

 

I am really pissed off and need to hit someone/something right about now, but very tired from using that 4 foot bar!:stickpoke

 

My local dealer could not take the car in till next Friday! And it has to be done NOW!

 

Right my rant is over, going take it out on the girlfriend now:sex:

Can you just imagine the Haynes manual description for this procedure ? 'Just remove the crank pulley'

 

 

Don't suppose you have a compressor and an impact wrench ? Might be what is needed.

I think it's gone from a DIY to PSE..(Pay Someone Else) jobbie.....:moo:

 

I have loads of air tools, but no compressor.....:moo: (there for work)

I have the nut and area soaking in some hardcore stuff over tonight and will have another go in the morning, if that fails it will be early 'bonfire night' or towed to the local dealer and let them swear at me while doing it:p :p :p

 

Gotta run, she's all lubed up and ready.....:eyebrows:

You can make your own tool or buy the special one from toyota to undo crank bolt ( i have both ) there is two 8mm bolt holes in the pulley to allow you to hold the pulley and undo the nut. I had to order the torque wrench to get one over 300nm. As for removing the pulley get a pulley remover they are about £15.
