B10m mk 3 motorhome diff gear ratios
Please anybody out there for some advice. I am halfway into building an ex city bus 1989 Volvo b10M mk 3 coomeng body fleet no.202, 9.6 litre turbo diesel mid mount with ZF HP500 auto 4 spd trans and EV85B final drive 487.1 diff ratio. I will be flat towing a D22 Navara dual cab with a 3.8 Bluefin boat on roof and a 900 Triumph Bonneville Speed master attached to rear of rig. I believe 378.1 diff gears will get me to 100 klm per hour plus some. Im having trouble finding this ratio and any advice would be greatly appreciated and thank you. At present bus flat out 85 klm per hour andwant to reduce revs and gain fuel economy.

You might want to look at changing the gearbox to a 5hp500 as you have 4hp500, the 5 speed box has an overdrive of .83, it may be easier to find than a diff.

Never thought of that and thank you for your time to answer and yes the diff ratio 378 is very hard to find but I can get a 356 ratio but sounds a little to high and its an EV85 not EV85B and I don't know the difference, not sure what the B stands for and once again thank you.

Is there anybody out there that can tell me where to find my Volvo b10 history as I wouldn't know where to start and would be great if I could get some service history and even better a workshop manual. Im about to cut open the rear so I can also carry a triumph motorcycle and a Suzuki Vitara with me and live in the front half. Thank you.
