Can some kind soul outline the procedure to remove and replace the accelerator cable from a twin carbi late bus ('75). Cannot find it in my manual and have never attempted it before.
Cheers

Undo the back end, undo the front end, draw out the old cable.

Refit is reverse of removal.

It is that simple. My wife did ours a few years ago, and that was on the side of the road.

It is that simple... as long as the tube that the cable runs through is in good condition.

When I did mine, there was one place under the middle of the bus where the tube was partly crushed. I had to cut this section out with a hacksaw to allow the thing on the end of the cable to pass through. I re-joined the cut section with some vacuum hose and a couple of hose clamps to keep mud out of the tube.

I also had trouble where there was a bend in the tube near the gearbox: I had to slightly bend the thing on the end of the new cable to get it to go around the bend, and then straighten it once I got it fed all the way into the engine bay.

But don't let me put you off, it is something you can do yourself, so go for it!

Cheers boys.. was a doddle.. learning something everyday. Now all I have to do is figure our why the accelerator pedal still sticks to the floor.. linkages all look fine, got me stuffed.

BTW Helbus, saw you screaming up Cantebury road yesterday in that unmistakable bus of yours.. like s**t off a chrome shovel it was!

That wasn't me, that was the wife It's her bus.

soft notch, is the return spring there?

the cable passes through the firewall, backing tin through a small bit of tin tube which over the 30 odd years of use and abuse will usually be loose and can sometimes have grooves worn in it about the thickness of the cable, two things happen the cable wears and freys and can also jam or be very slow on returning to idle

Return springs are all intact.. and linkage works perfectly when moved by hand...and while tube is loose cable moves freely. Have checked the conduit under the bus and there don't seem to be any dings that would restrict the cable. Spoke to a mechanic yesterday who is equally as baffled and suggested it may by the peddle mechanism (late type with the rod running along a tube on the floor).

If you unattach the cable at the pedal end, and remove the spring, can you move the pedal freely by hand? Or do you feel resistance in the pedal movement?

There's resistence.. the pedal will stay in position rather than drop to the floor.

Sounds like your answer is there: crud and old dried grease in the pedal tube thing.
