volvo fm7 truck

V.W.L 11

can anyone advise me on the type of gearbox these have???thanks

trackcar

there were several gearbox options with the FM7 all of which are Volvo's own gearboxes

the most popular was the 9 speed manual, it's a 4 over 4 range change & crawler gear
also available was a 14 speed manual, it's 3 over 3 with a splitter gear & crawler

Like anything, it just takes a bit of practice. If she has a nine speed, you can more or less forget about the crawler, I can't recall ever using it. It's a simple 4 speed, the same as your rigid, the only difference is the little switch at the front of the gear lever. When in 4th and looking to change up through the range, flick the switch up first, then as you pass through neutral heading back to where 1st gear is, you'll hear a nice solid thunk as the gear box crosses to the high range. Then just carry on as normal for the remaining gears. Simply reverse the procedure for downshifting.

The splitter used in conjunction with the range change on the 14 speed box is a second little switch mounted on the side of the gear lever. This also should be pre selected but you don't pass the stick through neutral to make the change, just dip the clutch. This has the action of "halving" the gear you are currently in. The only thing that tends to catch people with them is the change from 3rd to 4th. It's like changing from 3rd to 1st, it seems like an awkward shift but I far prefer that box to the nine speed...

Have fun with it, I can practically guarantee you'll crunch it a few times to start with....

just getting a chance to reply to you now,was out for a lesson yesterday,had no real difficulty shocking with the exception of trying to get the truck into reverse,it grinded a few times but the 4 over 4 gearbox wasnt an issue otherwise
