Main thrust bearing shards*****

Discussion in 'Mech Tech' started by Ash9889, Mar 23, 2017.

  1. Hi all and first post so go easy!

    I've been restoring my bay for last 9 months. I brought a gearbox from someone who said it came out of a beetle with 1600 engine.

    Well I've put it in with difficulty and connected all up but wouldn't start. Really struggling and drawing lots of power.

    I pulled the engine and have noticed metal shards around the main thrust bearing and on the gearbox input shaft.

    I assume I have the wrong setup. Any ideas how I would identify the parts and realise my error?

    Thanks

    Pictures always help
    Welcome by the way
    Are the metal shards in the bellhousing?
     
  4. Is it a type 4 engine ?

    Or shards of Aluminium from the bellhousing - too large a diameter flywheel?

    That's what I was thinking?

    Any pictures, @Ash9889 ?
     
  7. Sorry I realise now that I cannot upload pics from phone will do in the morning on computer. I'm running a 1600 motor with a 002 gearbox. The shards are inside the clutch bearing but I'm looking closer and it doesn't look like the clutch bearings on the Internet . Almost as if there is another piece of metal inside the clutch bearing before the input shaft. Pics will help will do that ASAP.

    Can anyone tell me the size of flywheel I should have for a 002 gearbox?

    From memory, most of the flywheels are the same overall diameter with different clutch plate recess diameters.

    The bellhousings are different depending on years, from what the Tom Wislon book reads
     
  9. if they are the same size I also take it they are interchangeable from engine to engine..im putting the as code fly wheel onto the other case as it will have the bigger clutch.....

    The type 4's are for sure, we went for a 228mm one from a 2.0 motor on our 1800 case.

    I would imagine a type 1 is the same as the gland nut thingamy will be the same thread regardless. My Tom Wilson book is at home else Id look :)

    What gearbox code is it ash? Should start with 2 letters, probably AT or similar if it's a 1600 bug box. 002 is probably a part number.

    Get some photos of the clutch, and the release bearing up as there are 2 types. You probably have a late release bearing and a early clutch or vice versa.

    Yes type one flywheel are interchangeable chaps :thumbsup:

  12. has the engine been rebuilt, did the thrust washers go in. the flywheel hasn't been moving backwards and giving the case a rub perhaps....
     
  13. Wont all the ratios be wrong for a Beetle gearbox, if it is put in a bay?
     
  14. It's what all the split and early boys use

  15. Hi Ash, did you have to fabricate mounts to fit your gearbox? A beetle gearbox wouldn't fit in a bay without lots of work.
     
  16. Picture of the offending issue

  17. Looks like wrong bearing /. Clutch compatibility issue

    As above. thats a late release bearing with guide, if your clutch is the early 3 finger type, then thats your problem.

  20. It does look like the clutch pressure plate has ground the end of the bearing guide.
