H4 gear shift

[jul...@cityaudioservices.com]

Hi

My H4 has a 'short shift' lever which is OK in 123 and usually 4 but terrible in and out of 5. Adjustment works to centre it properly but makes no odds to selecting 5.

I have no info on what was done to make it a short shift, though I'm aware of the trick to shift the fulcrum. The engine is a Mondeo silver top 2L. 

Has anyone any knowledge of this linkage and more to the point, how to improve matters? 

Thanks

Oops, just replied to you, not the group.

I would be very surprised if it was a gearbox from a Mondeo, the MTX75 on those is quite a lot bigger and would have issues with driveshafts, gearchange (Cable) and clutch (Hydraulic).
It's not impossible but i'm not aware of any H4 with Mondeo gearboxes, if it is then that could explain things.
I can tell from a picture if it's a MTX75

What info I have doesn't suggest any gearbox rebuild - where changes were made they were detailed, this was just listed as 'gearbox from a Mondeo - believed good' or something of that sort. Anyway, if 5th is out of kilter, it ought to be possible to feel that.

Many thanks.

If it's adjusted correctly (putting the locking pin in the bottom of the gearchange) then the fact it's short shift shouldn't make any difference to the gear selection.

If the gearbox has been rebuilt at sometime then it's possible the 5th gear selector isn't set correctly, this needs to be set manually when you are rebuilding the gearbox.
It can be done in the car (on the 2+2 at least) after just removing the gearbox end cover.

I could well have simply mistakenly inferred that from the context. I assume the Zetec block is no different between the 1.6L and the 2L, so a 1.6 box would fit. As I recall the info was that it was a box from a diesel! 

Anyway, I'll take a photo when I'm back (away today) and send it over.

The Mk1 Mondeo with the silver top Xetecs always had the MTX75 gearbox.

When the same engine was used in the 1.6 and lower power 1.8 versions in the Mk3 / 3.5 Fiesta and Mk5/6 Escort it had a IB5 gearbox.

The Mk5/6 Escort XR3i 130ps version had a MTX75 gearbox (as did the Escort Diesel).

As you say, the engines are the same and either gearbox will fit with a matching flywheel.

A common gearbox to use on higher power engines is one from a Mk3/3.5 Fiesta diesel as that was a stronger box but still in B5/IB5 housing so fits easily in the H4

Is there a marking on the box that tells me what it is? If I can find that out, is there a way to obtain details of how to make adjustments? I'm pretty sure it's not in the Haynes manual!

Thanks again for the wealth of detail.
