Hi,
I again rebuilded a failed gearbox for my Spitfire 1500
Now 2000kms later..
Yesterday drove onto the main road.. bang!
And prop banging..
Stopped on the side of the road, making noises in all gears, needed a pull to home 😔.
Today took the gearbox out.
Clutch like new, opened up the box.. ffs..
Tooth missing on the laygear and input damaged.
This gearbox did fail before.
Also laygear(mostly shaft failed) and took everything with it.
So now it had:
-new NOS laygear
-new input
-new OD mainshaft
-new japaneese gearbox bearings etc.
Now the latest bang it made.. what could caused it ? 🤔🤔😔
It was all very smooth exept gear changes (suspected the syncro's)
Ps.. truelly hate Spitfire gearboxes now, had them fail lots of times now.
