Gearbox problem

Recommended Posts

Hi

My LHD mk1 1100cc 4-speed manual gearbox is not in gear properly when I change gear when driving, I.e., once I put in 1st gear, it goes to reverse position....I have trouble finding 1st gear as it feel loose. Could it be missing part to make it more firm in gearing? Something call scyro mesh? I forgot it’s called.

Will it worth rebuilding or get new 5 speed box as I have replaced engine for 1300GT engine? I heard MX5 5-speed gearbox can fit straight in on standard gearbox tunnel?

TIA

Seán

First thing to try is a new gear-lever. What stops you selecting reverse when going for first is the spring loading on the lever.  If the lever feels all floppy it may be the circlip has come off on the top of the rubber cone on the lever which pre loads it.

Ok I’ll check it later when the Storm Ciara have calm down 👍

One more thing, what type of standard gearbox on 1972 mk1 1100cc? Type 3 or Type 4?

Thanks

Well there isn't a 'commonly known' type 4 box so it won't be that and type 3's weren't fitted to Escorts - Type 2 was the gearbox fitted to all non RS model Escorts. Swapping to a T9 or Mazda box will likely require a whole new clutch and flywheel to suit due to different input shaft dims and splines!

Colr6's diagnosis sounds spot on - if you can select reverse without pushing the stick down (known as a 'lock-out') then that's where the fault lies.

If your taking the lever off make sure the lever to shaft saddle is still in place or damaged. That can send gearshifts wacky too if badly worn.

It’s a type 2 fitted to all non RS models. Ratios between the 13gt/e and 16 sport differ between std 11/1300 boxes apart from that same box. Obviously yours been a LHD the starter is on the other side

I managed to remove the gear stick to inspect what’s missing or damaged/worn but I haven’t a clue what’s I seen, can anyone spot something amiss, I have not see any circlip or plastic shaft saddle, see pics below

Well the plastic saddle is still there but your gear lever has had it just as Col said. The sections shouldn't separate like that unless the circlip is missing. One of the nylon sections has split too. Time for a modern replacement with a alloy base and thread.

Where do I get replacement part with modern alloy base and thread? Any links to find

You should have a little circlip above the rubber to stop it all being slack? Unless youve already removed it to lift the rubber bit?

Don’t think I have but I’ll re-check if circlip still attached to top of rubber gaitor later tonight or tomorrow morning 🤞🏼

Yep that groove should have a clip in, the clip type is an "E" clip, very similar to a circlip, but does not have the 2 little holes for the circlip pliers to open up, when looking down on the clip it does look like a small letter "e", and they are a tight fit , you will need to squeeze one into the groove with a pair of pliers. Not sure what size the clip is sorry.

 

Good luck,  Al.

Manage to find that ‘E’ shape circlip and after bit of fiddle, it locked in but not fully in to the groove, will it pop off?

Hi,

 

The "E" clip will only go into the groove as far as the depth of the groove, as the clip is more than 180 degrees around the machined groove, the self gripping design of the "E" clip will keep itself locked into position.

 

The only thing to make sure,  is that the groove is clean,  so it allows the 3 points of the clip to bottom out in the groove, clean out the groove carefully, you don't want to make the clip a sloppy fit, also check that the clip has not been over strained,  in that it has lost its spring tension, they are only pence to buy, but you need the correct size.

Al.

Sorry guys but as I mentioned before the whole lever really needs to be replaced, putting the circlip back in is all well and good but it doesn't change the fact that the nylon ball joint area is already crumbling and split. It doesn't have many gear changes left in it.

What is that darker brown thing with the split some kind of cover? The actual plastic bottom and top seem ok? Id just pack the thing with a bit of grease and put it back together? Probably go on for years!

Its like a domed washer that allows the the main nylon parts to slide smoothly against one and other. (effectively like cartilage) It is the first part to fail but it is also a few millimetres thick and when it falls out completely in pieces the whole thing becomes loose and the spring tension is lost.

Thanks for this advice, I’ll take risk and use the gear stick for a while till same problem comes up again then I’ll get new one 🤞🏼
