I've been thinking of getting the RTS flywheel and pressure plate balanced for the mini.

Now I've just spoken to the local place who ideally want to do it with the crank out the engine. I agree with this but don't particularly want to take the engine to pieces at this stage although, with it out the car, now would be the time to do it.

The other thing is cost; he has quoted me £100 which is a bit more than I'd expect.

Your thoughts?

That is twice what I pay, but yes best to have all the rotating assembly done at once.

If something is worth doing, it's worth doing half of.

If you are going to bother balancing then it needs to be done with crank and the pulley as an assembly. £100 sounds a bit steep but once offset against posting somewhere not local then maybe not so bad.

I knew you would all say that! Just don't have £100 cash at the moment and seem to be getting further away from having either the mini or metro back together

Have a word with Sprocket.

What the mind can conceive the mini can achieve
MITP 2012 17.01 seconds 1/4 mile against "The Don"
MITP 2013 16.83 seconds 1/4 mile

I'm a rotating equipment engineer. I don't know much about mini engines but I do know about rotating stuff. We balance shafts,impellers, couplings all the time.
If the crank has been balanced already and you get the clutch/flywheel assembly balanced separately there will be no problem when the two are matched together.

I should of said that to balance the clutch / flywheel assembly u will need a mandrel or a another balanced crank to mount it on. Balancing it as a full assembly would be best thing to do but I'm just saying if it's in a built engine and you don't want to strip it you do have options and that there is nothing wrong with joining two separately balanced items.

Yip, should have said the local place told me that. The price is for crank and flywheel Was going to work out more expensive if i just had the clutch done as opposed to the crank and flywheel together

I use a scrap 998 crank with a good taper specifically for the job of balancing the flywheel and clutch.

It is also worth mentioning here that a standard factory flywheel will have been balanced and you really only need to balance the RTS. It costs the same where i get my balancing done with or without flywheel

The place i spoke to said they would need to make a mount up to do just he flywheel clutch. It was actually half the price to do both flywheel and crank together as they wouldn't need to make the mount. They did lo uggest i stick it in as is and see how it was

Mitsi Evo 7, 911, Cossie. & all the chavs ...... won no problem

all my engines are fully balanced, and i can tell you 99.9 of the weight comes off the cranks sorry to piss on your bonfire so to speak*frown* when an engine is fully balanced it runs so smooth its like a swiss watch and you can feel it ...............it transformes the car IMO*smiley* and the feel how it drives its like a breath of fresh air compared to a daily run around motor

it needs to be done and that price is a little steep max £70 in my book for all the rotating assembley

steve, looking at the price, if I have to send the stuff down south and get it back again I'm probably looking at the best part of £25 return on postage so £100 isn't so bad if I do decide to go with it

well I've decided to nail it all back in the car as is and see; it was sweet reving up before, it was only when the clutch was being feathered I had any vibration and I've put that down to the sintered plate
