Hi all I have a problem with speedo cable connection on engine side it has rotted away and it needs replacing on where the cable inserts? How do I change the inside part? Thanks Tom

Do you mean this part?

If you have nimble fingers you can usually access from below and undo the single bolt holding it on.

Hi sorry it's the actual pinion? Inside engine what the cable slots into? The engine is out of car. Cheers Tom

Yeah, it's pretty straight forward.

 

There's a gasket you'll need to replace and while you're at it, there's a seal inside the housing as well that could be replaced.

 

There is one bolt that holds the cable adaptor on, whip that out, remove the cable adaptor and pull the pinion out.

 

You'd be best advised to remove the Pinion and count the teeth on it before buying a replacement as there's a few different types.

Hi moke spider do I need to take the side casing of to get the pinion out or just take the plastic adaptor that the speedo cable screws to of with one bolt holding it in and then pull the pinion out? Thanks Tom

Here I've got my fingers on the bolt, undoing the last few threads of it

 

 

 

and lifting the Pinion, with the Cable Adaptor out. Usually, the Pinion will stay in place and need to be lifted out after removal of the Cable Adaptor, so don't panic if it doesn't come out together

That's excellent mate do I just prize the pinion out with a flat head screw driver? I thought I had to split the casing on the side and get to it that way easier job then I thought cheers Tom

If the pinion does not want to come out, remember that it needs to twist slightly, and may need to be pulled with something like Mole grips. Not to be used on a good one of course.

 

The end casing can come off in situ, after draining the oil and removing the radiator, but you should not have to unless you need a different drive gear for a ratio change. Some people apparently pull the engine but there is room to do it, with a jack under the engine. Obviously the mount comes off.

 

Only do it if the pinion will not come out, or there is another problem, as you need some gaskets.

90% of the time, you can grip the shaft of the Pinion with your fingers and it will come out, the other 9.5% of the time, just grip the square part with a pair of pliers.

 

The last 0.5% you'll likely end up wreaking the pinion to get it out and there's a slim possibility you will need to remove the whole end cover to get at to do, those these from my experience are very rare.
