Jet 22-44 oscillating sander - drum slipping under load

[RogerS]

Does anyone know how to fix/mend/adjust this? The manual suggests a v-belt but how/where to adjust it I have no idea.

Or does anyone know of an engineer who does on-site visits in my neck of the woods/

Am in real doo-doo on this until I can get it fixed.

TIA

Now sorted and sincere thanks to Andrew Neal-Hopes at Brimarc for his help.

For anyone with a similar problem...

Symptom...drum slips under load.

Likely problem.. the small bar (bottom rh of picture) sits in a groove on the drum shaft and held in place by set screws. A sort of woodruff key. The other half meshes with the connector on the motor drive shaft (big complicated black thing - centre photo) Screws came loose and the bar fell out.
