Hi guys. I own a 1986 Bedford MJ truck flat platform, with a TC Electronic Repair Radar body fitted (but truck is ex Ptarmigan) The truck has been fitted with a recon transfer box a month before release (May 2009). The speedo is the newer round type, but the speedo reads very low. If I'm doing 40mph on the Sat Nav it's only showing 25 odd mph on the clock. The needle is rock solid on the go with no bobbing at all, so I'm thinking the recon transfer box might be fitted with a speedo drive gear that was for the earlier horizontal clocks? What is your thoughts on this? Do they have different drive gears for the Bedford MJ transfer box, or is it the speedo head I should be looking at? Also when going on the flat the truck will eventually get to about 45-50mph. But when you get to a hill the speed drops off dramatically to the point that I'm having to change down into 2nd gear. Once in 2nd the truck accelerates quickly again (as if it's too low geared), but if you change into 3rd the truck will die on you. I can't hear any turbo whistle whatsoever under load, is this normal for an MJ? Is there a higher pressure turbo available for this engine? Is this slowing down normal or should they hold their speed pretty good? It's been 8 years since I was driving them in the Army, so time has erased the memory of them. Any help would be very much appreciated.
