supra100 Posted February 5, 2006 Share Posted February 5, 2006 Good afternoon all!. Right my problem is that today I've attempted to change the timing belt myself but ran into a problem. I don't have access to the toyota SST tool to assist in removal of crankshaft pulley. I've tried heating the sod, I've tried the buzz gun, I've tried a long bar, I've even tried lodging the bar on the chassis leg and cranking the engine in an effort to crack the big bolt but it won't budge......... The joys of DIY....... so anyone got any ideas as I need to get belt off as it's laminated!. Cheers in advance:sos: Link to comment Share on other sites More sharing options...
Simon Posted February 5, 2006 Share Posted February 5, 2006 Had a similar problem with my delica, ended up making up my own sst using angle iron, torque wrench and long pole to get the leverage. Had to bend the angle iron over on itself and welding it together to get the strength so it wouldn't bend. Link to comment Share on other sites More sharing options...
JohnK Posted February 5, 2006 Share Posted February 5, 2006 Heating the pully is a big no no, it destroys the rubber damper, you may well need a new pully now. Sorry cant help you with undoing it, usually the starter motor trick as you have tried works. Link to comment Share on other sites More sharing options...
LeeT Posted February 5, 2006 Share Posted February 5, 2006 lucifer has some ofthe proper tools made up at £30 each or if i remember correctly used to hire the tool out Link to comment Share on other sites More sharing options...
carl0s Posted February 5, 2006 Share Posted February 5, 2006 uh oh. Like John said, you you should keep a close eye on your crank pulley from now on as it may well break apart and go flying through your bonnet or radiator Link to comment Share on other sites More sharing options...

supra100 Posted February 5, 2006 Author Share Posted February 5, 2006 It's a 94 auto tt. The heat wasn't too sustained and the bolt wasn't glowing. I was cautious when heating for fear of damaging crank etc. Just a little heat to try and aid etc. If I get it off I'll have a proper examine just in case. It wasn't smoking or anything.

Lucifer Posted February 5, 2006 Share Posted February 5, 2006 Christ sake... Nooooo Don't use heat as you'll harm the rubber bonding on the pulley. Common mistake. I have this tool now made up ready to go. £30 each. Invaluable if you want to do this bolt on an auto. Martin Link to comment Share on other sites More sharing options...
veilsideTT Posted February 5, 2006 Share Posted February 5, 2006 Take the inspection rubber out of the gearbox housing. Turn the engine slowly until you see one of the bolts come round on the flywheel. Wedge a nice big pry bar in there (hold it there!) and get someone to crack that crank bolt off. Disclaimer: I have done this in an emergency once but i have no idea on problems that my arise with your flywheel after doing so. My flywheel is fine AFAIK! But do so at your own risk! You really need the SST to put the crank bolt back in if your going to torque it up properly (i hope you are!) HTH Scott Link to comment Share on other sites More sharing options...

Terminator Posted February 6, 2006 Share Posted February 6, 2006 If you have applied heat I would seriously recommend getting a new pulley. Link to comment Share on other sites More sharing options...

Terminator Posted February 6, 2006 Share Posted February 6, 2006 You are in good company though, quite a few toyota garages have used heat to get them off. Link to comment Share on other sites More sharing options...

supra100 Posted February 6, 2006 Author Share Posted February 6, 2006 ARGHHHH. Thanks for all advice chaps. I have no probs buying a pulley I just want the sod off. I'll have another go tonight. If not I might be purchasing Lucifers tools etc. Have a good day all:) Link to comment Share on other sites More sharing options...
Lucifer Posted February 6, 2006 Share Posted February 6, 2006 Geez guys, £30 to stop all that pain , I have 10 made up and not one person has asked for one! Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 6, 2006 Share Posted February 6, 2006 Geez guys, £30 to stop all that pain , I have 10 made up and not one person has asked for one! Post a pic, not sure if your tool is for holding the pulley while you undo the bolt, or for pulling the pulley off the cranks nose once the bolt is removed? Ideally you need both.

Lucifer Posted February 6, 2006 Share Posted February 6, 2006 Post a pic, not sure if your tool is for holding the pulley while you undo the bolt, or for pulling the pulley off the cranks nose once the bolt is removed? Ideally you need both. The two tools I have : 1. Crank pulley tool - For removing the Crank pulley Bolt. Holds the Pulley still by the use of 2 M8 Cap Screws into the pulley an sits under the Chassis leg. 680MM long 30mm Hole Spun on the end. 2. Crank pulley remover, the complete kit for removing the Supra crank pulley properly without chipping anything or bending the runners. Pics shortly.

JohnK Posted February 6, 2006 Share Posted February 6, 2006 Guys, are there any tell-tale signs to tell if a bolt has been heated in the past? I'm getting paranoid now... Yes, usualy a random time after heating the 2 parts part company. Link to comment Share on other sites More sharing options...
supra100 Posted February 11, 2006 Author Share Posted February 11, 2006 Okay it's the weekend again so I decided to have another go at the dreaded crank bolt. Made up a jig with angle iron and two M8 bolts. Lodged the sod on the chassis, got a 6' long piece of scaffolding pole and placed it over the breaker bar..... a good old bit of hee and haw and crack I got the sod. Old crank pulley came off easy enough with some pullers, put new one on and rebuilt it all torquing up on the way. 10 mins once you've got bolt out the way. Built it all back up and when holding the tensioner down to get drive belt back on the tensioner bolt sheared...... a blessing actually as it must have been really weak. Managed to get the remainder of the M10 bolt out, replaced with new super super bolt, got drive belt on and she runs like a dream. In all less than 2hrs. Thanks for all advice given. :D Link to comment Share on other sites More sharing options...
