You don't need to replace the bottom pulley if you know what your doing and know how to tiime these engines up without using the pulley as a guide.Have a look in the FAQ section, there is a thread which details where to put the woodruff key on the crankshaft so the bottom end is timed up correctly. However, if you're not comfortable with that method then just buy a new pulley.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

Not necessarily mate. As long as the rubber damper material is in good nick then it's safe to carry on use it.I would mark the slipped pulley with some tip ex against another non-moving part while it's bolted to the crank. This way it ensures that when you're checking the timing after fitting the belt by turning the engine over that that belt hasn't slipped. I would also mark the crank pulley (the actual gear/cog) against the block before you take the belt off using a bit of tip ex. That way you'll know if it moved while you were working. Chances of the crank moving while you were working are slim, but you would want to know if it did. ________________________________________ Deepak Gohil |

The FAQ you want is under the title 'Cambelt Timing Guide' and it is located on page 5 of the FAQ section.  (Can't do a link on my phone at the moment) ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Personally though, Get a billet one  That way you are free of crank pulley related worries. ________________________________________ Ex- Phase 3 China GTi-6 T-Reg |

The ones Rich W sells are top notch, lighter for less rotating mass and no chance of the pin hole slipping.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Do you have to fit a new crank seal when fitting the billet pulley, like the fly wheel has to ?________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

No, and neither do you need to fit a new crankshaft oil seal on the flywheel end when changing the flywheel either. Obviously, if you take the gearbox off and the flywheel and find it's leaking then yes, but otherwise no. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Ok thanks, when cam belt was being fitted i forgot about the new seal. I have heard of the fly wheel crank seal leaking after a light weight one was fitted.The pulley crank seal was fine, no leaks, so i guess the seal will have to wait a few months. ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

The crank seal leaking will not be down to fitting a lightweight flywheel. It will have been coincidental.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Yeah sure, well while things are off then fitting a new seal both sides is generally a job worth doing at the time i suppose. I guess you never know when they might wear out.________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug. Black 306 GTI 6 Standard, was 60k mileage, bargain!!

Yes, to be honest if you've got the gearbox, clutch and flywheel out it is worthwhile changing the seal as all of that will need to come off at a later date if it subsequently started leaking. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Getting back to the crankshaft oil seal behind the flywheel, given that it's such a pain to access I would always fit a new seal when changing a clutch or flywheel, for the tenner it costs it just makes sense.________________________________________ R H Davey Welding Supplies.

Agreed, it does help though if you've got the proper tool to fit it in to the correct depth. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

I have a bearing/seal fitting tool which sits them just below flush, flush is ok but level is more important than flush. ________________________________________ R H Davey Welding Supplies.

if it were me i would buy a new pulley, or use a known good one to time it up. Tipex is not the best as it does not tell you if the timing was correct on the belt you took off. |

Not worth the risk of using a slipped pulley IMO Just would feel like a ticking bomb to me,just waiting to come apart and take your cambelt out for good measure! ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |
