Fluid Flywheel Issues

Post by Pablo110 »

I've never been happy with the Fluid Flywheel on my Conquest Century. It has always been harsh, when a gear is selected. even at 400 RPM or less, the car tries to jump forward, in reverse it's as much as I can do to hold it on the brakes. Plus it leaks like a sieve.
So today was Gearbox off day. After much wrestling and a bit of Anglo Saxon, I got the gearbox off. Removed the Flywheel cover and the Driving member, and removed the Circlip. It was here I found I was not the First visitor. The Oil seal had been beaten in with a small drift , judging by the dents in the seal. However the worst problem is the Bronze Bush. This is heavily scored in its thrust face, and is scored in the bore, and has about '020" play between itself and the spigot on the driving member.

So, Questions, is this why my drive is so harsh? Will a new seal take up that much play? Are the bushes availiable and how much of a pain is it to fit?

Regards,
Paul

I would say the harsh take up is more likely to be a gearbox problem than FF. A minor adjustment should solve the problem I would have thought.

Not an expert, but I`m with Andy - it sounds like the harsh take-up is more likely to be the gearbox. I would have thought that harsh take-up is the least likely result of problems with the fluid flywheel - but then there are folk on here who are far more knowledgeable than me.

Terry, I agree with these posts - this sounds far more likely to be a gearbox issue. The bushing in the FF is easily pressed out - at least it was on my DB18 - but sourcing a replacement may be an issue! FWIW there’s a lesson here: although it takes longer to do it’s far better to remove the FF for seal replacement. It sounds like your previous ‘visitor’ replaced it with the FF still fitted hence the damage to it because it would be difficult to install it with the driven member in the way.

Hi Terry,
I had the same problem with a Conquest.
Check all the linkage that is operating the gear change.
There should be no play in it.
When this is fine it is just about setting the gearbox correctly.

Thanks for all the info Guys. An incorrect FF oil seal stopped play until today. Be careful, there are still some counterfeit items out there. Anyway, the correct seal was purchased today and fitted. FF back together and oil tight, Spare Gearbox fitted and oil tight. Back to work tomorrow so a few evenings this week should see Her back in working order. Looking forward to Driving her again.
