rotoflex couplings

I though I would put in my $0.02 as one who likes the donuts. I think
they give the car a unique feel and are part of the car's character. I
am so used to them I don't even notice the windup any more though I do
tend to be a bit kinder to the driveline on this car because of them.

Mind you, if one ever breaks and strands me somewhere my opinion may
change. I do check them for wear every year or two and I also keep a
new one and tools to change it in the boot at all times as insurance.

I agree for same reasons, I broke one on my 1600 in 1965 hot dogging around town, it was the early weaker style donut, the half shaft wrapped up in the hand brake rod and I was stopped dead in the middle of the road unable to move the car - the only time the hand (park) brake really worked. I enjoy the origional "feel" of the car as well as the perplexion of someone new trying to drive it.

Keep your stick on the ice!

Its interesting this talk of them breaking on Elans, when they seem
to have been fitted on a number of Lotus race cars (including the F1
car for a period?). However, the Elan racers seem to have had
problems with them breaking and switched to sliding spline/uj
versions, which - along with personally disliking the feel of
the 'rubberiness' - is why I am fitting similar Tony Thompson Racing
versions to my hillclimb +2. David.

Just remember in race cars they get replaced after each race , if not after every practice .

Also all race cars including F1 are now fitted with CV joints, even in the days when Lotus were still in race cars,
that was after they swiched from donuts to uj's.

I think I know why !!!

Leave a 35 year old, rapidly vanishing, classic british sports car
unmodified??
Horrors!!

Scott, these classic british sports cars were being modified 35 years
ago, particularly for competition. One only needs to look at the elan
homologation papers and 26R parts lists.
I fully understand why someone would want their elan as it left the
factory (though exactly how that was probably depends on the day of
the week it was made). Equally however, it seems to me quite
legitimate and authentic (if not truly original) to modify an elan in
period - especially if it is used in historic competition today.
Let's also not forget that elans were built down to a price, and more
expensive period Lotus parts (solid driveshafts, aluminium radiators,
alloy diff noses, LSD's, oil coolers, solid steering mounts etc) do
not necessarily make it any less characterful.
Each to their own. Regards, David.

Umm, when was the last time a Lotus race car drove 100k miles? Over 30 years? Thought so. Replace em. They were cheap, that's why he used them. They break and put holes in your car.

Hey Scott

To all you budding engineers out there
the standard plus2 inter.driveshaft is approx 15"(with rotoflex
couplings)
Question:-
if one was to make a replacement with a sliding spline how much play
should be allowed +/- to allow for suspemsion movement
thanks
