The damaged sensor affords less clearance, but there must've been a hell of a lot of movement to touch it in the first place. <- Where has all that movement now gone? Bearing movement would cause allow the trigger wheel to venture out/toward the wheel at the rear of the diff, but why only on overrun? _________________ Posted: Fri Apr 06, 2007 10:29 am Roofer Forum Moderator   Joined 31 Jan 2004 Posts 19711 Location Dunno.

Beats me Posted: Fri Apr 06, 2007 10:22 pm Neil Established   Joined 22 Jan 2002 Posts 17309 Location Woking, Surrey M3 Compact wrote: Was the damaged 'prong' on the outer (wheel) side of the trigger wheel in the diff, Neil Unfortunately I can't remember that. I may be able to deduce it by offering the sensor up to the backing plate tomorrow. It's possible as Simon suggests that the damaged wheel is a red herring. I've been racking my brains about the bent sensor blade - it didn't look damaged in any way - I presume that normally all the blades line up?! Is it possible that I bent that blade while draining the oil? That's feasible if the blades stick out the back when the backing plate is off - but even then is quite unlikely. I'm currently in the New Forest but again I'll check that tomorrow. That said, if the blade was bent by me then I can't understand how the sensor got bust - I think it's most likely that the sensor breaking and the blade bending occurred at the same time. So as Tom says, why isn't there obvious bearing damage? Hopefully I'll find some answers tomorrow, wish me luck! Who's coming round to help?! _________________ blog | twitter Posted: Fri Apr 06, 2007 10:41 pm Olly Section Moderator   Joined 29 Jan 2002 Posts 3708 Location Horizontal Still not sure, I'm going to the boat race tomorrow (read: going to a pub near some water, soak up atmosphere, soak up alcohol) but the race starts at 3ish. So if you want help till about 1-2 then I@m more than willing. What time were you thinking of starting? And in answer to your earlier question, we've done backwards, upsidedown is the only way to go now!

If you don't help Neil to the point of finishing, I'll grass you both up on the forum. Here's my suspected broken diff noise. Any suggestions Olly? _________________ Posted: Fri Apr 06, 2007 11:09 pm Neil Established   Joined 22 Jan 2002 Posts 17309 Location Woking, Surrey Well, I'm going to bed in a minute, so should be up at a reasonable hour. I've got to go to Vines to collect the sensor, and then somewhere else (don't know where yet) to get some gloves and some engineer's blue. Then I'll start. Ben might be around too. _________________ blog | twitter Posted: Fri Apr 06, 2007 11:15 pm Olly Section Moderator   Joined 29 Jan 2002 Posts 3708 Location Horizontal Well give me a call when you're starting.

Posted: Sat Apr 07, 2007 10:54 am Neil Established   Joined 22 Jan 2002 Posts 17309 Location Woking, Surrey Simon - it's the longer sensor prong that's broken, on the outer, road wheel side of the trigger wheel. Woking's only engineering supplies can't get any blue in until next week, so I'm carrying on regardless. Current status, both diffs on the bench. _________________ blog | twitter Posted: Sat Apr 07, 2007 11:15 am M3 Compact Administrator   Joined 18 Apr 2004 Posts 41106 Location Reality.

Imo the gears on the CWP will naturally try to work apart, which would move the trigger wheel outward on the rear of the diff. <- BF, Roofer, Ian agree?

If the pinion is fixed, but the crownwheel is 'free' to move, I'd expect the crownwheel to try to move away from the pinion (tapered teeth etc) when the pinion was turned? (Understand what you mean about 'pulling together' Roofer.) It's all a bit of an irrelevance now, tho. _________________ Posted: Sat Apr 07, 2007 7:09 pm Roofer Forum Moderator   Joined 31 Jan 2004 Posts 19711 Location Dunno.

Roofer wrote: Quote: I'd expect the crownwheel to try to move away from the pinion I'll go for the opposite Explanation req'd Roofer. I understand how the mesh could try to pull the crownwheel forward in the housing (in to the pinion), but can only see the gear faces repelling each other which would tilt the crownwheel 'axle' in such a way that the trigger wheel would move outward in the sensor.

He must have that open diff back in by now! _________________ Posted: Sat Apr 07, 2007 8:53 pm Roofer Forum Moderator   Joined 31 Jan 2004 Posts 19711 Location Dunno.

Don't matter anyway, cos it's fcuked. You don't get your whole Geordie pound tho, as it wasn't refitted. _________________ Posted: Sat Apr 07, 2007 9:50 pm Roofer Forum Moderator   Joined 31 Jan 2004 Posts 19711 Location Dunno.
