Shift Linkage Gaiter repair...........attempt

These things aren't easily obtained and though I eventually have ordered new one's, thought I'd share my repair attempt:

My process included:

1) De-grease and clean (krud kutter, safe)
2) Glue together broken areas/pieces (ultra bond superglue)
3) Rubber revitalize treatment for seals (zymol)
4) Spray rubber to help strengthen (Plasti Dip)
5) Silicone spray inside
6) Grease the linkage prior to install to assist smoothness

Not perfect, I'll admit, at least for my 1st attempt but think it will work.

Feedback appreciated.

Im thinking that plasti dip will do almost nothing seeing as it is designed to be peeled off...

Surely another part from another car maybe not exact same which would work?

I believe I would have just used something like shoe goo to join the broken sections, and used that as a temp measure. Good old soap and water to clean a little if needed.

Super glue (cyanoacrylate ester) in its cured form is brittle and designed for rigid, thin-film shear- type applications. Since the rubber is flexible and will exert a tension load on your glue joint, it will likely fail pretty quickly. The Plastidip provides no strength although it might protect the cyanoacrylate from water (which will degrade it).

If I were attempting this repair, I'd use the same glue found in inner tube repair kits and use a narrow strip (from one valley to the next on the gaiter) of inner tube applied across the break on the outside of the gaiter. The downside is the repair will cause the other areas of the gaiter to flex more than normal, eventually leading to another failure.

My creaky memory recalls that a rubber boot from some kind of Jeep can serve as a replacement for the commonly-broken Lotus piece.

Can anyone share particulars?

I think you might be thinking of the boot around the actual shifter rod that can be used from a wrangler

Yeah, to date I haven't found any compatible boots for these gear links, not that it doesn't exist. I also tried to find a neoprene sleeve for a pen/cil thinking that might work but nothing found.

I have found facilities, mostly in china, that will make bellows to order, but don't need 1,000 of them Even the one's I ordered 3 weeks ago, had to be factory ordered, and I'm still awaiting them from the U.K.

I went with the ultra bond superglue as part of its marketing was a video cutting a bellow and bonding back together. When I glued these up, I didn't do just the valleys but peak to peak..

I've never heard of shoe goo, but is it flexible? That's why I experimented with Plasti Dip. Yes, it does peel off but might at least add some protection. Otherwise, mostly useless stuff.

Probably a futile effort, but worth the engineering experiment effort to me.

Thanks all....

Shoe goo is quite available, and does not get 'hard', and is quite common for rubber repairs and such. I used to use it to repair radio control car bodies. Google it, and you will find a bunch of hits.

would any of these work? you might have to trim to length.

I would have also used rubber cement and a segment of the tire to repair (or RTV silicone)

I'd have used black RTV to bond the two pieces back together. It stays quiet flexible and it would be safe.

On that note... I'm pretty sure the clutch cable adjustment gaiter on my bike would replace that. Can you give me some quick measurements?

IamBatman,

Only a couple of those bellows might actually work, or adapted to work, but they aren't the cheap one's.

firefighter1c57,

Hmm, I've used black RTV as gasket sealant but didn't try as bonder.

Yippee,

So, got some goodies from postmaster today. My new linkage gaiters showed up from the U.K. - finally.

At first I was like WTF!!? They aren't the same as priors and figured would have to engineer these too in order to make fit.

But then I realized they do fit, but inside the rings, not over-top and then zip-tied down as before. Well, this is my thinking so far, guess I'll find out for sure once she's back on the streets. <g>

I got these new one's from SJ Sportscars.

yeah, mcmaster carr isn't the cheapest but usually you can find anything you need to fit. They ship pretty quick too.. depend on your location but I usually get whatever I order from them in one day. They are like the Amazon of the mechanical engineering world. Anyway I'm glad to hear you get it all working

Looks good...thanks for the 'finished' pic.

Yeah, now I realize that the gaiters you referred to were the ones by the translators. I often see them torn on friends' Esprits. (When you have a lift in your garage, you find that you have a lot of friends! )


Something new to me was the rubber boots on the translator heim-joints themselves. Was that a later-car thing, or did the rubber "fall off" the Renault-transmissioned 4-cyl cars I have seen????

Yeah, I imagine a lift is like a boat, everyone wants to come use it <g> I'd like to get a lift for doing DIY on my Esprit.

Believe the boots were from '96 on but can be retro-fitted on the heim-joints for 4-cyl. There is also the complete overhaul kit for gearchange translator for both 4 & 8-cyl which includes the boots. Check out parts A082F4149F and SJ082F0040 on SJ Sportscars UK, lotus car spares, parts and accessories for sale worldwide and servicing and repairs in the united kingdom, sj sportscars limited, independant lotus specialists

I was underneath mine checking on a fluid leak when I spotted my torn boots, otherwise I'd likely never have known myself. Figured I'd replace them since easy enough and provides protection. I've also checked the other boots throughout the area and have cleaned and applied Zymol soft seal protect-ant to them all.
