    Gearbox Swap

    After the C2C run the old gearbox was making a lot of noise and I was finding that the gearing was too low for a long trip so I decided to upgrade it to a type 9 box. I've got hold of one so since the weather is going to be crap for a while I've decided it's a good time to get them swapped :-)

    I'm on a slightly different adventure since I have a Ford engine and gearbox to deal with I find that the easiest way is to drop the engine and box out the bottom of the car. Since I only need to get the gearbox out and I don't want to go to the bother of removing the exhaust and inlet manifolds I'm going to try just taking the gearbox out on it's own.

    There are lots of people on here who have experience with the 1300 models so I'm sure someone can help. Earlpart is very good for marina spares apparently.

    Did you have the original 4speed ford and are swapping in for a type 9?

    Re: Gearbox Swap

    T9 has a spacer added between the gearcase and rear-extension to accommodate the 5th cog, so you may need to fiddle about with xmember/mounting & gearstick a little, plus the propshaft could now be too long...unless Ford shortened the extension on the T9 to compensate. Never seen 4 & 5 speed boxes side by side so just musing aloud..!

    I had to do a lot of research but the conclusion is that they are very close in terms of fitting. The tail piece was redesigned and is shorter than on the type-e box so overall it is about 6mm longer and I have more slack than that in the propshaft length. Also the gearbox mount and the gearstick are out by a few mm but I suspect that the dimensions that Marlin used for the Ford variant were based on using a type-9 box because the slack looks like it's in the right direction. I'll find out when I come to fit it though

    The main problem that I can foresee is the speedo cable which seems to be a bit tight... Judging by what I have read it may require a hole in the tunnel so that I can route it through the car rather than under it.

    Re: Gearbox Swap

    With my type 9 I ended up with a 90deg drive. Not necessarily ideal but it works. I did not like the idea of routing the cable through the cockpit, and as it was a custom cable I had to have one made up anyway.

    Re: Gearbox Swap

    On the plus side we managed to get the old gearbox out and the new one in without removing the engine, which is a bonus. It all seems to fit ok, including the prop the big problem is that the gearbox mount is a long way further back than on the type-e box so I'm going to have to fabricate a new cradle for the mount to sit in. In fact it's now in the narrower part of the tunnel so the Ford mount will not fit, I'm going to have to reduce it's width to about half way through the bolt holes. Has anyone else seen this problem on a roadster? Got any ideas for a novel solution?

    Re: Gearbox Swap

    When I fitted my type 9, right now I can't remember if I used a Capri or an Escort standard cross member but folded its wings up to fit inside the transmission tunnel.
    Using dome headed bolts, to minimise carpet interference, I made up a couple of short plates with nuts at either end. In the narrow gap between tunnel, bracket and gearbox it made it easier to attach. Especially after I had dropped a couple of nuts into the mount hollow. Somewhere I have a pic, I will look it up, hopefully.
