Default Carrier gearshift binds in first gear

Gidday Matt and Tim,

Thanks for the replies.

I have disconnected the gear lever itself from the main connecting rod by removing the two bolts near the driver's seat, so as to isolate this. The gear lever and its sliding mechanism slide smoothly. However, by trying to move the main connecting rod that runs down the hull to the gearbox by hand, you can still feel the binding effect at the other end.

I've removed the arm that actually attaches to the transmission and the binding effect is still there so it is in the linkage/connecting rod/gearchagne rod area somewhere.

I experimented today with loosening the two brass bushes holding the gearchange rod and ball joint and then putting a little upwards pressure on the front bush before retightening it. I felt this made it very slightly better but in saying that I can now feel the binding effect in 3rd gear.

It probably makes sense that this binding in 3rd was there all the time but with the gearbox being mainly in 1st gear I just may not have noticed it that much.

So I think that it is somewhere in the linkage arrangement where the rod is in its most rearward position and it is binding somewhere in that position.

I figured there couldn't be too many possibilities and the alignment of the two bushes seems to be the only possibility to me.

I reckon my next step is to disconnect the main connecting rod at the universal joint, and fit the gearchange rod and ball joint in the two brass bushes (with nothing else connected) onto the hull and see if I can isolate things from there. That way nothing else can be invovled.

Any other bright ideas or do you think I am on the right track?

Thanks

Darryl
