Spit steering joint head scratcher


Recommended Posts

Hello Experts (and anyone else who is stuck with this!).

Bought new rack to shaft joint as part of my resto. 2 issues. A. Different lengths B. Absolutely no chance of getting a bolt through from one side to the other with the shaft in place. 
Bought from the leading supplier. 

Am I missing something? Shame to put the old one back as (as you can see) I’ve been super thorough on the rest.

thanks

Alan

It's just wrong. The Spit does not require a universal joint since there's no angle of inclination between the lower column and the input on the rack. Something like an XJ6, where the column is inclined to rack, needs a UJ. What you've been sold is just not a Spitfire part.

Assuming the splines are ok I'd recondition the existing unit. Try Chris Witor at Suplaflex for replacement rubbers.Or failing that, Moss.

ive seen a shaft with a reinforced hose and hose clips used to replace the UJ     i mean  yikes  O dear 

dont do it 

I seem to recall the replacement modern uj was mid life fiesta based  its nothing special  but does need the holes in the right place

is pretty  fundamental

So did I, fitted it and the splines were so bad it didn't grip the shaft. Plain dangerous! Fitted my old one as I didn't know about Chris Witors part. 

Send it back!

The problem is the the (so called) correct part has a life expectancy measured in days. Very poor quality rubber.

Reconditioning is a possibility using polybush parts. However, only the early type that use wire locking on the bolts is really suitable. Later type (as pictured in the first post) have the bolt ends crimped. To remove teh bolts you need to file/grind them, and re securing is tricky. New bolts do not seem to be available.

The UJ type should last very well. I have used teh chris witor one from a t2000, quality is good. Cheap versions are variable at best. It was also sold as a gp4 escort steering joint.

I've done it, surprisingly easy using the polybushes. Early joints come up for sale often enough (usually until you need one!) and the metal parts rarely wear, unless they're badly rusted. 

Some of those black UJ versions were originally intended for Ford Fiestas hence the difference in size of the column.

Must get a set of poly bush’s but when I rebuilt the Spit insulation assembly around 20 years ago If I remember I used cable grommets cut in half still going with no issues, but I initially had problems getting the split and splined joint staying tight on the shaft so I replaced the std shank hex head bolts with Allan head where I could get more purchase on them!

Pete, that's where my dangerous UJ came from! 

Just sayin', hopefully your one is OK.

Duly Noted, Ian, 👍 I will keep a careful eye on it. The "original" was beyond redemption anyway. And allegedly NLA. Plus I have "converted" to PAS anyway.

I recently upgraded to the poly bush's in the std insulated joint can't advise if any better due to Lockdown No.6.

PeteH I know the UJ joints are probably all metal thereby hopefully providing some earthing across it, but shouldn''t there be a earth wire across the two bolts to ensure a good earth for the horn, similar to the insulated joint, the rack itself has it's own earth strap/wire to the body even tho' it's of all metal construction, maybe belt and braces.
