Towbar fabrication for Volvo B6FA

Postby BigBus4Us » Sun Jan 20, 2019 1:48 pm

Hi All,
Does anyone know any information about GCM weight capacity for a Volvo B6FA? I have a 1984 Custom coach Volvo that has recently been fitted out as a motorhome. I want to get a towbar fabricated, but the fabrication shop were unable to proceed as they said they needed the GCM (Gross Combination Mass) value which was not printed on the original compliance plates. The issue the fabricator had was the cut chassis behind the rear wheel to a sub chassis to accommodate the boot, and whether this has a load bearing capacity, also the capacity of the engine/gearbox to handle a load. I have tried multiple times to get an answer from Volvo but seem to get the run around from one person to another with no answers. Has anyone been down this road before and have some helpful advice please.
Regards,
Damien

I believe that the B6FA had a GVM around 12 tonne; presumably a bus chassis would not normally need a GCM rating.

You might need a qualified auto engineer to come up with design to meet your circumstances.

Thank you
I found an engineer to give me the design and certification. Only problem is that he wants to extend the chassis through the boot to come down to the subchassis. If I didn't have a water tank and washing machine in the way I might have done the work.

I've just been to a very reputable towbar and exhaust dealers in Mandurah and any towbar built for a vehicle pre 1987 does not need to be certified
