STEERING RACK GAITERS
by Lorne Goldman

The JK and Quaife gaiters are very distinct. The traditional JK gaiter is one piece with 2 end cones.The Quaife has an anodized metal centre piece, two pleated gaiters and two end cones.

If they split, there is no immediate danger involved, though it is a MOT failure. These racks are so simple and solid that, as you have already discovered, they work fine with or without the gaiter. But, on the longer term, you do want your rack's innards to be clean and lubricated ASAP. But if you put on grease, expect the insides of your rack to be covered with road debris fairly quickly. The grease will act like flypaper.

QUAIFE GAITER

The current configuration has been used since soon after the Quaife was adopted Morgan in 2005. However, last I heard (2015) it is "back ordered".

On the Quaife side, I do not believe they produce these gaiters themselves. They likely buy them from a jobber. And if they did produce gaiters, they are prohibited from selling them direct to us. But it is not difficult to find them from an auto parts jobber or source a generic gaiter off ebay.You simply need the two piece format and they can all be trimmed to suit.

JACK KNIGHT CENTRAL GAITER 

These are a more serious problem The JK Cebtral gaiters were made on a JK bespoke moulding by laminating silicone on it and then peeling it off. They are flimsy as hell with a number of important watchpoints to them if you want them to last beyond the installation. (See other aricles on GoMoG) There is also a new upgraded version, similiar to the Quafe advertised on their site. It is very good. Problem is Jack Knight is not currently responsive. People write or call and nothing happens. Or if they do make a contact, there is no follow-up after. This is a great pity as there are about 8000+ Jack Knight Morgans out there and this fellow could refurbish them, or change their turns-to-lock to a variety of options. He could even decrease the turning circle so that the wheels do not damage superform wings.. That being said, since I learned the watchpoints in installing them properly, I have been using the current one on the car for the last decade without a problem, and being me, I long ago put an extra in spares when they were still easily available.

That being said,  I am working on a replacement for the JK gaiter...but slowly, with the ETA sometimes in 2018. Essentially, I hope to come up with instructions for the home garagiste to replicate the Quaife and upgraded Jack Knight format. If successful, it will end this supply nonsense. These things are not rocket science. I have Jack Knight, and I will disassemble it so we can have a repair Manual to supplement David Poole's adjustment instructions. 

JACK KNIGHT END GAITERS/CONES

IMPORTANT WATCHPOINT 1: Jack knight Steering Rack END GAITERS. Just like the Jack Knight Centre Gaiter discussed below, Owners/Dealers very often ruin them by an improper installation installation.The error made is simple. The installer pushes the cones on too far rather than using the intent on the cones and matching it to the clip (or tie-wrap) indent at the end of rack. At the first full turn, the pinion pokes through the gaiter. They promptly leak after that, eventually damaging the pinion for lack of any lubrication. A ripped end gaiter will also allow road grit to enter the rack.. damaging it and/or making it difficult to steer. Many owners run to  much more expensive gaiters (10 times the price)

Nothing much to say about these except an important watchpoint. There are commonly pushed too far on the rack. As a consequence, the first time the driver takes a sharp turn, the pinion pokes through their end. To test, merely put them on and turn the steering wheel both sides to lock, and see if the pinion pushes them off before securing them.

INTERIM SOLUTION

For the moment, use a bit of fishing line with a needle and sew what you have back up. You can also cover the new seam with bicycle repair rubber glue and let it cure overnight. Then re-attach the gaiters to the center with new tie-wraps (which since I mentioned that 15 years ago become the Morgan standard).. That will keep most of the debris out and last anywhere from a day to the end of the car's life.


IMPORTANT WATCHPOINT 2
Jack Knight Steering Rack CENTRE GAITER The key watchpoint to fitting a Jack Knight gaiter so it does not immediately begin leaking lube is to position the spacers that slot into the pinion properly in relation to the gaiter holes for the bolts. If these spacers and the gaiter are examined closely, you will see the raised circle on the spacers serve a purpose other than merely joining the front plates to the pinion. This raised section around the bolt holes prevents the torquing of the bolts and their IDENTICALLY diametered washers from forcing the plates, on bolt torquing from crushing and splitting the delicate silicone gaiter between washers and spacers. They promptly leak after that, eventually damaging the pinion for lack of any lubrication.

LONG TERM SOLUTION

Do not fret about installing a new gaiter of any kind. I used to detach the entire rack to put one on. However, now I simply detach the non-steering column side and slip it on with the rack in situ.

The best long term solution is to find adequate replacement gaiters as suggested above.. I found a set for my project pretty easily by search in ebay under steering and suspension in other marques. You have a lot of leeway as these things are always pleated.
