Have you started on your carrier yet lew? It's Alex Denby here (steve's boy).

Hi Alex, a bit off topic but have been too busy painting the house... was hoping for more rain so I can spend some time in the garage, I should really get some photos up here of the project.
Forgot to say big D its also called molycoat.

Hi Darryl,

I had a problem with the gearshift sticking too, and found it was misaligned mounting blocks. We had replaced the engine bearer channels. I loosened the bolts a fraction and keep an oil can handy to oil it whenever we go out.
So far so good, and that is about 14 years!

At the Men of Steel event in Hamilton, I got a bellyful of sand as the hull plates are off, and that jammed things up too. A bit of time with a paintbrush to sweep the sand out of the hull and clear the gear shift shaft and mountings, and a bit of oil on the shaft and things were fine again.

How is it now that you have done the gear selectors?

Evening all,

Rob - have just reassembled the top. I cleaned up all the rods and fitted it all back together as per Lynn's instructions. No real problems putting it all back together but I've taken some more photos to have a look at first. Just wanted to compare the before and after photos to make sure I put it back together right!

What mounting blocks were you talking about?

Cheers on the coppercoat/molycoat Lew. I'm guessing I can apply a bit of that to the exposed areas now that it is all back together, or should I have applied that first?

Cheers

Darryl

The copper cote ,moly cote, anti seize etc. is a hi temp antisieze compound, but I personally think in this case that grease is much better.
It will be intertesting (one way or another) to see if you have gained anything. We are all learning.
Hi to everyone else.
Cheers. Lynn.

Hi

I've read with interest all the comments and suggestions, this type of problem is of course not limited to Carriers.

So please let us know how your various corrections work out and do they solve problem of temperature related sticking or difficulty shifting.

I've had a similar problem on Ford Truck transmissions of this vintage, in that case the transmission had been assembled from the best parts of a couple of transmissions with a few NOS parts thrown in for fun. In that case the problem was finally traced to gear on the spline shaft having a slight mismatch in machining and wear. That problem was only finally found by putting the various assemblies in the oven and heating them to operating temperature between 130-150 F. Discovered then that one of the gear clusters that slid smoothly at room temp bound up when heated. Fix a little careful polishing of the slide shaft.

Cheers Phil

Hi
I have had a few problems with the linkages have solved them now but have developed a new minor problem when i change gear some times the ball on at the bottom of the gear lever pops out the socket, when this happens it causes the gears to feel tight, something to just check is it the ball and socket playing up?

Hi Darryl

I meant the two fittings that hold the gearchange shaft to the engine bearer rails. They should be parallel, and in line. I think mine were not, so the shaft bound up. A boot was needed to kick it out of gear, with the engine off!

As I described loosening the bolts slightly gave enough clearance. They haven't come loose either!

I oil all the joints from front to rear to ensure smooth changes.
It doesn't stop the gears clashing of course, that's operator skill, or lack of.
