Volvo N10 Stuck in Reverse
17 May 2020 15:33 #210277
I have a 1981 Volvo N10 parked in a paddock which is stuck in reverse. The gear stick feels like it is in neutral, but the truck will only reverse. Does anyone know if this can be fixed while in the paddock?
A mate's 1418 used to do this every so often, but usually in a forwards gear, and often at an intersection! You are lucky because you know it's in reverse, if it was in a forwards gear you have to remember which one.
With the 1418 we would either give the truck a push or a pull while the driver had the engine running and his foot on the clutch, and holding the gear lever where the selected gear should be. The bit of motion from being pushed or pulled seemed just enough to make something jump, and then you had gears on the stick again.
I have had it happen on our old C1800 Inter truck once, and it's quite a regular occurrence on our 564 Inter front end loader. With them i always have to lift the stick out the top of the gearbox and line things up again. It usually means it's time to build the end of the stick up again.............
Is it a 8 or 16 speed? Usual problem with these is to do with range change when it won't go from one to the other or is stuck in between in which case you have no gears. First check would be to go through the linkage to make sure nothing is slipping on it's splines, Otherwise it may be that the selector widget in the box has got very worn and jumped out. Not unknown for the selector cage to be broken . Either way it involves lifting the lid of the box.
I had a B61 where the compound box selector would come out and jam between the rails ...........and as mentioned ,the early IH AB and C line 1820s had a similar fault where the box would jam between first and reverse.......then if the stick housing was lifted off carelessly ,one of the selector springs could stick to it ,and fall out on the road .....IH redesigned the whole top of the gearbox in 1970.
I had a G88 in the 70s ,and went to the bearing shop to get a bearing set for the 8 speed box......anyway ,at the counter the guy says .....youre not going to bring all these back ,are you?....I says Why?.......he says ...Volvo do an exchange gearbox cheaper than the bearing set ......He was right ....I got an exchange box for $400,and it turned out it was brand new........Seems Volvo prices have gone up some since then.
