I am the vw timelord and have had many incarnations in a TSC style. Made my millions by people giving me their cars thinking their engines were fooked due to the oil spewing out of every seal and gasket. I would get the car and replace the blocked breather on the the back of the block and punt it on! Happy days
Found this whilst doing research for Big Belly's Big Blue Brother. (love alliteration, or is it illeration?) Now, if the Ford Homologation Specials, with 10s of millions thrown at them, can't get their vibration dampers right, then, what chance have yous lot got? ps. I only do research for him cos he sends me Newky Brun to clear the sink!
Ah, this is where you've disappeared to! Question is, how can you spot a flywheel flexing on a dyno? This all comes back to the harmonics thread, which I was going to bump for a different reason. Just to clarify I do not ship Newky Brun. It's posted to me
Cheeky bu**er. You damn well know which two of your secret missions I was working on! I've a good mind to make the full list public! Banned, maybe, but one or two, or three on here, will clamour for my re-instatement. (I hope). Mind you a lot more will send you slabs of Newky. Better you ban me NOW! Or, alternatively, you can Air Lingus me a cask of Tim Taylor's and a box of fish n' chips. It's all done with smoke and mirrors my Big Blue Boy. Ho, and "strobe-lights" and a 16mm cin camera. Been there, done it, at GKN-Laycocks.
Scarey. Luckily most of you are not pushing LHD cars around. Drivers of G60s and similar Left-Hookers need to reinforce their bulkheads, or wear kevlar full body armour!
the scary thing is that was a LHD car would hate to think what would have happen if that had gone through the bulkhead
Flights are down - sorry, no can do Anyway, shoosh and keep at it! There is light and beer ahead. (Light may be your torch, interimly).
I'm surprised Eurospec haven't taken action on this tbh. Better to do a recall than face charges if someone gets killed. Of course it'll take someone getting killed to make them do something.
Smaller businesses are too hand to mouth to take this view. I've seen it in the UK and in Europe - they've got staff and rent to pay, so warranties and refunds don't come easy. If there's race use involved, forget it. There are no warranties.
I've finally dug these pics out of a flywheel that came off. One for the engineers to get into a fizz over Obligatory weight supplied!
Fatigue crack originating from the stress caused by the bolts acting as dowels once they came loose I would say. Is this your flywheel to destroy Chris? It would be interesting to cut out crack section and split them to see if rubbing existed either side of crack. It would be interesting to see if the holes had clean smooth chamfers and also that there as ample chamfer at the top of hole so as not to interfere with the radius between head and shank of bolt on the underside. Either way it looks like the bolts are coming loose for some reason, maybe the chamfer/radius interferes giving a false torque wrench reading, after a few cycles this interference would be pushed back, causing them to loosen. I wonder if oil, or say Loctite 620 was used? Both to get an accurate torque reading, and also for locking purposes(loctite) (this is nothing to do with torsional vibration if the bolts are tight)
Yes, it can be cut up as necessary, though chances are I don't have the equipment. What cuts need doing?
Cut out the cracked piece between bolt hole and centre bore. Break it then on crack if it doesn't/isn't broke already and look at both crack faces for rubbing.
