These drums our well known for numerous points of failure.
Additionally as these are now much easier to come by, they’re a fantastic upgrade for heavy abuse trucks.
The most common problem on these is the band surface can become damaged due to band failure.
This happens due to a lack of fluid or fluid pressure loss.
Very typical this may get as bad as striping the band lining off and running metal to metal.

Another problem area is the bore of the drum where it rides on the pump stator support.
This is were the normal metal sealing rings cut the land points into the drum resulting in pressure loss or bleed off.
Over time the sealing rings can cut into the surface of the bore resulting in a partial applied or fully un-applied clutch drum.

This is an extremely common spot to have wear, light witness marks is a sign of normal wear.
However, if your finger nail catches the mark at all, then the drum will need replacing.
If you do not replace the drum, then this may result in even more problems than we have described.
This fluid pressure loss will lead to burnt clutches and bands, as well as slippage when engaged.
