Carrier shifting issue

[Ben]

I have an adjustable linkage, somewhere in box. It's shown in Nigel's first book I believe.

[Lynn Eades]

Mine was butchered beyond recognition (cut out and welded into a fixed unit)
I am not sure how they were built one after the other with no real adjustment.
With so many components that could be slightly out, it is amazing that everything worked. I bet there were issues on the production line, or at least when they first went over to the fixed set up, pre war in England.

The adjustable system was probably canned because it too would have been a "for ever coming loose" nightmare.

Jim, Have you had any of the gear change apart, while the engine was out? If so, make sure you don"t have a "too long" bolt in the tube under the engine, that is hitting the floor before it is properly in gear.

[Jim Burrill]

Thanks for all the references and help!

In this case, we have not had the engine out since it came from the previous owner. He did say he had trouble going between 3rd and 4th, but otherwise the shifting is all functional.

After some engine cleanup - oil change, cleaned and resealed gas tanks, rebuilt the distributor ( Diver Helmet) and some carb cleaning it runs pretty well and has power.

But the whole tranny issue is new to us. Will see about the replacement shift fork from Mac's Auto and then see how bad the gears are. Usually 4th is pretty un-chewed.... especially compared to 1st.

A carrier Driver from the Middlesex Independant Machine Gun detachment with the 49th Div told me from D-day(+19) to VE day, he rarely had his carrier in 4th. Lots of 1st and 2nd convoy conga-lines.

Must have been a very very slow convoy buddy.

Check the engine mounts.

Remove the engine covers and have a mate watch while you put the engine under load in first and reverse.

If the engine "heaves" off the mount, then replace them.

... on the splines of the short gearshift lever.

There was a discussion I heard recently amongst carrier folk about the possibility of being one spline tooth out. This would mean the wishbone was not at right angles to the vehicle axis when in neutral, and hence affect the throw.

Food for thought

[Michael R.]

Yes, ... that point needed emphasis. I recall you understand those fine splines very well Rob.

"Performing the speed change test may assist to determine if the CTL 4950 is bent, or simply not properly installed on the shift lever. You could place a straight edge against the long side of the adapter to visually inspect it."
