brianm Posted April 16, 2006 Posted April 16, 2006 scott early flywheel is flat later pot type has big lugs on it You can't mistake the two, early is flat on working face, later pot type is recessed by about 13mm or so. Chill Scott, it will come good. Quote
scott beeland Posted April 16, 2006 Author Posted April 16, 2006 Sounds like an early one on mine. It had a 2-3 mm raised edge but has now been machined perfect flat to get rid of a wear ridge from a ceramettallic paddle. Interestingly Demon Thieves now list a Helix Group N clutch plate and cover for an XE Westfield and even list the part numbers; so I'll be ringing Questmead on Tuesday to sort out exchange Quote
pete g Posted April 17, 2006 Posted April 17, 2006 scott i take it your number is different. the helix cover is exactly the same as standard unit, but they drill out the springs and fit stronger ones. i shopped around for best deal but they all appear to do same deal .cheapest with discount was SBD but then gets dearer with there silly postage fees. im wondering if becuse you hve machined of the outter edge this is giving you a problem.does the cover not fit to this part. why did you not just get another flywheel.

scott beeland Posted April 17, 2006 Author Posted April 17, 2006 Karl W measured the raised edge on an old flywheel today and it was 2mm. My set up has the cover mounted on 2mm washers to replicate the raised edge so it shouldn't be any different. I'm aware that the cover I have is the helix version of std but with uprated fingers. But when the cover bolts are tightened the fingers push inwards way too much. Questmead have my cover and friction plate part nos on computer so I'll be cross referencing with the D Tweeks "Group N" Westfield XE part numbers tomorrow iN RETROSPECT GETTING A NEW STD FLYWHEEL MIGHT HAVE BEEN GOOD OPTION BUT i'VE ALREADY SPENT ABOVE BUDGET AND JUST COULDN'T STRETCH IT ANY MORE Quote
pete g Posted April 17, 2006 Posted April 17, 2006 scott i have a good spare flywheel you can have if you still having problems by stoneleigh show.can bring up in car.but would rather not hopefully you will be sorted by then. Quote
scott beeland Posted April 17, 2006 Author Posted April 17, 2006 Cheers Pete. I'll let you know but we should be able to get this to work as it's a technique that's not unique to my XE Westfield Quote
scott beeland Posted April 17, 2006 Author Posted April 17, 2006 My clutch cover receipt says 60-4626. which when cross referenced to the DT Catalogue (wasn't DT supplied) says Astra 2.0 16v gsi to 92 Astra 2.0 gsi 16v F20 Westfield Vauxhall 2.0 16v is listed as 12-4626 Houston...I think we have a problem Quote
scott beeland Posted April 18, 2006 Author Posted April 18, 2006 Further discussions with Questmead and SBD today. Helix cover 12-4626 is apparently a standard cover 60-4626 is apparently the uprated cover. Questmead are getting me both TO TRIAL FIT. Can anyone confirm either of these part numbers as used in thir car? Can you also state fact that the standard cover will cope with the torque a QED 450 cammed engine? Or will I need the uprated one? Also getting me the Helix friction plate 70-4628 (westfield XE 16V). Anyone using this part?? The problem may lie in the fact that the AP friction plate I was fitting on Saturday (apparently there wasn't a Helix plate listed when I started buying stuff) is 8mm thick as opposed to the Helix being 7.62 mm?? Is this likely cause of my non operating clutch? Whatever I end up fitting next week HAS to work...So please help out your friendly technophobe spanner phobic Quote
Blatman Posted April 18, 2006 Posted April 18, 2006 FWIW, a standard Pinto cover coped with no problems with the Cossie spinning at 7500rpm and making ~235bhp. Quote
scott beeland Posted April 18, 2006 Author Posted April 18, 2006 Does the torque capacity of a clutch also relate to the weight of car it's in? ie...The std cover can only cope with X amount of torque when in a car weighing over a ton but can cope with more torque if the car is sub 600kg?? Come on you VX XE boys with similar engine spec....What are you using?? Quote
Martin Keene Posted April 18, 2006 Posted April 18, 2006 Does the torque capacity of a clutch also relate to the weight of car it's in? ie...The std cover can only cope with X amount of torque when in a car weighing over a ton but can cope with more torque if the car is sub 600kg?? Yes, with a standard XE in a Westfield, the standard clutch will have a *much* easier life. I'd be surprised if you couldn't cope with a standard clutch. Quote
scott beeland Posted April 18, 2006 Author Posted April 18, 2006 That was my non scientific thinking too. Right...I'm off to bed now... PLEASE can we have some good solid opinions from the XE boys by the time I resurface today Quote
scott beeland Posted April 18, 2006 Author Posted April 18, 2006 [Yes, with a standard XE in a Westfield, I'd be surprised if you couldn't cope with a standard clutch. It's not really a standard XE though is it now? Quote
Martin Keene Posted April 18, 2006 Posted April 18, 2006 No, but your going to be running about 60% more power (150 to 240) in a car which weighs about 45% less (1100 to 600) than the car it came out of, and in the car it came out of it would have been capable of a GVW of something around 1700kg. But, it will get more brutal treatment on starts than a cav, especially with you driving... Quote
scott beeland Posted April 19, 2006 Author Posted April 19, 2006 Any XE boys that can confirm correct Helix part numbers? Quote
