Dunning & fairbanks or Baileymorris will sort you out with prop requirements.

Get the car checked out for probs first before diving in, also consider whether you want fit a reverse box at any point as again props required different again. You don't wanna make another boo boo

Errrr.... yes there is a cush drive on nearly every bike I've ever seen, it's between the rear sprocket and the rear wheel.

As I said the Cush on the bike is very soft compared to a trt prop which is still almost solid





eerrrrrrrrrrrrrrrr

Errr.... Sorry I wasn't too clear, but just to put some detail on it, there is no rubber cush on the chain drive (well, a simple drive at least). Bikes do, but not in the car application.
My car has the chain wrapped around a 48T sprocket bolted straight to a Fiesta plate differential, there's nothing in the transmission line (bar a few tripode joints). Every gearchange goes straight through the chain, which really lets you know about it.

My comment was just that all BECs that I've built/raced with many engines and configs aren't entirely noise free! I was simply encouraging the newbie owner to use the pedal on the right to smooth it all out a bit.

Oh, that's not good mate, let's hope it's not the box. Do you live far from MK? Hope they get it sorted for you quickly.

Thought i would give an update on my repairs so far.

Took the car to MK who did a road test and confirmed there was a problem"Terrible LOud Clunky noise" not normal at all.

Ok they took off the Diff , opened it found it to be in rarther good condition, made some slight adjustmets and refited to the car, This made NO difference to the fault.

Then they swapped the Diff with one they had lying about also siad they had replaced the propshaft centre mount /bush.

Called me on the phone said the cars sorted,,,, I picked the car up today and guess what still the same.!!!


So Now i know there is a fault, the Clunking is not the norm for a BEC ,,, but dont know what to do....


I am thinking about sending the Bl@@@dy thing to AB performance to see if they can sort it.

Any advice would be welcome

Start with the gearbox output shaft to propshaft adapter, known to work loose.

Then take a look at the clutch, with there being no cush drive, it can accelerate bearing wear and wear in the cutch drum, look for grooves where the plates sit in the outer drum, which cause back and forth movement in the clutch an clunks as drive is taken up.

Sounds normal...
It's an aquired skill that can only be achieved by practice, which means driving as much as possible,.
It reminds me of golf...one day you can play perfect, the next day crap, it needs practice, practice, practice.
If you don't get any better at it...sell it

If it was down to my driving and lack of practice,, i would have expected the lads at MK have told me that,

As i have said they Danny And Gaz both confirmed its not a normal noise, and there is a fault. Problem is they cant find it

I had a look round your car when I was collecting my diffuser, a real great car you have bought there (apart from the clucking that is), top spec, hope you get it sorted

That sounds like a good move,, the output shaft can that be checked on the outside, hmmm might strip the clutch this weekend too

Thanks

Jokeob, put your location in your profile, there might be more people than you think locally that could take a look.

My clutch seems to clear better sometimes better than others, wouldn't mind getting it replaced but when I get the revs right it's seamless, out with the kids tomorrow aim to be back for 5 could meet opposite Memphis Belle bout 6 on the little carpark? I'll text you around 5 anyway, weather permitting...

Have you confirmed it is fitted with a TRT prop. When my prop was made they didnt use TRT tube even though I specced it. It was off and replaced after about 500 miles. Was bloody horrible.

When friends drive my car I notice the clunking as they are not used to the light clutch,paddle shift,dog box etc.

Been in the OPs car today, really nice car and goes well, BUT big clunk under our elbows, feels like something lose around the prop/diff area on gear takeup, not his driving...An expert ear required...

Another known prblem, if you're pulling the cutch is the centre to work loose in the basket casting, this causes much drivetrain slop

Well decided to have a look at the clutch

Drained the oil and removed the clutch case, and plates, its had a Barnett clutch fitted and all the clutch plates look like new.

I have noticed if i hold the clutch basket and pull backwards and and forwards the basket and the cog move about 2-3mm.

Also if i try to rotate the basket back and forth it moves maybe 4-6mm while the rear cog stays still.

Wondering if this is normal
