After some recent work using my Belle Maxi 140 concrete mixer it developed a fault. It would work ok in one direction but when the drum was turned to face the other side, it slowed down and then stopped. The motor was struggling and eventually the overload device popped out and the motor was overheated. I decided to completely overhaul the mixer as a similar replacement to this 17 year old machine was now extremely expensive
Step 1: Strip down
Luckily these UK made machines are still in production and most of the parts are available.
The internet was useful for finding and printing off an exploded diagram, invaluable prior to dismantling the unit.
It proved to be an extremely filthy job so I took care to minimise the muck by carefully disposing of it at each stage. I washed off all the greasy and dusty parts in kerosene as they became free.
