Ok so it 'was' a routine gearbox oil change but these three peices of a once ok component fell from the bowels of my gearbox sump in three peices no idea where the forth is lodged!!!!!!!!!!!!
Actually they were stuck to the magnet but that makes it no less painfull.
Any of you gearbox experts fancey identifying said part before I take the box off and down to the garage?
Weird thing is it drives (drove)fine with a very sweeet gearbox (for now!)

you may get away with new bell housing , but will need to check main shaft bearing ect whilst apart.
do you know the history of the box? has it always been in your van? any one done a clutch/removed the engine/box for any reason?
all hopefully to be confirmed by the experts.....
Thanks Billy,
I only have the paper history and the van is just back on the road after 3 years.
I do know the engine was replaced by vw in 2001 so it would have been off then.Other than that i have no previous info sadly.
yep that's part of the oil thrower, chances are your bellhousing is knackered too, the oil thrower is an interference fit in it and must be absolutely centred; I'd expect the input shaft seal to be leaking and the bellhousing to be wet.
The input bearing may also have failed or the engine may not have a spigot bearing fitted or that has broken up but usually you'd notice that as clutch problem, and the input shaft may also be damaged as it runs in close tolerance in the oil thrower.
Box out job I'm afraid.
If input bearing has failed the mainshaft will likely be toast too
The oil thrower is there to minimise oil being drawn along the input shaft by rotational capiliary action (hence reverse rifling pattern in it) and enables the oil seal to cope with the load, the oil seal on it's own can't cope as the crown wheel is constantly splashing oil onto it as the diff and wheels rotate.

Shaft is toasted where it has rubbed against the remains of the thrower...The whole affair was being supported by the genuine vw oil seal on the bell housing so really glad I took the box out now.
The remains of the oil thrower saved the bell housing and the missing piece of the oil-thrower jigsaw was still attached so all debris now accounted for.Well thats one piece of good news at least.
I aquired a very good oil thrower from a petrol bell housing to relace my broken item and ordered a gen vw spigot.Thanks to Aidan who supplied a replacement input shaft ,input seal and input shaft clip.
After a full day of prepping and with very helpful advice from Aidan I am all back together again.
I constructed the gearbox lifting jig for my trolley jack from the wiki guide and this made replacing the box much much easier.
Gonna need a new slave cyclinder to finish off but went on a short test drive and all is just dandy again.
Thanks for your comments and help getting me through this (one of many) campervan crisis!LOL
