After reading the post the other day about the failed propshaft UJ's and my continued vibration I'm gearing myself up to replace mine.
Just a quick question though, what purpose does the Rubber coupling serve? Mine looks cracked and brittle so I'm presuming it's the original and seeing as I'm going to have the prop off I've decided to replace it as well as a matter of precaution.
But what does it do?

regards,


Dave
 
They are also used in place of UJs on vehicles that don't need large articulation in the prop shaft (RWD saloons with independent rear suspension for example). They are a cost effective alternative that reduce the amount of moving parts.

The boxes were pretty good. Bit of a bastard to strip and rebuild as i recall. Lots of presets to sort out. Failing was the flexi coupling to the gear stick. Used to go floppy. You could waggle the gear stick around all day and not find a gear.

Hillman Imps the memories flood back. Pneumatic throttle, what an abortion that was. Powered by a genuine water pump engine. Scaled down Coventry Climax. :D:D

Pneumatic throttle was short lived. Biggest shortcoming was the water pump, the front bearing had no protection and failed very quickly leading to water loss and overheating which fecked the head. I modified the pump with a front cover and seal and packed the space with grease. No more failures after. It was a good little engine, quite hard to tune but went like stink when you got it right.

Yes a fun little motor and pretty hard to break. I modded a Mini with an 1100 block and Hillman Imp HC pistons. Lots of machining and buggering about but it went like **** off a shovel. I to was a boy racer at one stage. :):)
