Removing Speedo drive

[Mirboo Moke]

Hi all,

Quick question. Has anyone had issues with a very stubborn Speedo drive? I am trying to remove my old one to transfer it to a new gearbox, but it won't budge. I would use heat etc but am concerned that I may damage the gears.



Thanks,
James

G'day James,
The speedo drive should slip out pretty easily. The shaft will turn a little as the gear unwinds itself.

The shiney brown substance, could it be some sort of a sealant thats been used to fix an oil leak? That would make it hard to budge.
If you use a bit of flat bar and cut a small slot to go over the square drive and use it like a key to give it a wiggle, it should free up.

Hi,

I would say not to use heat as there is a plastic cog/worm on the other side of the side of what you can see that would likely melt.

You could take the end plate off the gearbox and that should give you access to the other side and you might be able to push it out.

I think it may be loctited in. No luck with brute force, so I think I'll be looking for a new one

Im not sure of a brown loctite, usually red, blue or even a yellow'ish wick in style product.

Maybe if you take the whole cover off like Terry suggested, it will make it easier to break the seal.
Sounds like your not going to re use the gear box?  James, still wrap it up in plastic to stop the work shop sweeping dust getting in. Never know if you might need something from it in the future.

Thanks HP,

Already off the gearbox and still no luck, even using a hammer and bench vice. The brown is dirt and grime from a very dirty gearbox case, but there was a tinge of red around the edges of the bush. The old gearbox will be kept in a sealed plastic box for safe keeping, once I can transfer over a few of the old bits and pieces to the new one.
