ok peeps ,

looking at getting my new cossie bottom end lightned and balanced ,

now i kinda have a vauge idea of whats invloved ,

but how exactly to they balance the parts ?

i know they need the full rotating mass of the bottom end , i.e crank rods pistons , flywheel , clutch cover ,pulley ,

do they need bearings ?

also does anyone know any companies in the north east of england that can do this ,

just trying to get an idea of how much it costs,

i reckon its got to be benafical to revving and stress on the engine ,

any inputs folks ,

No....... Bearings aren't included in a bottom end balance.

Just the rotating/moving parts.

dont have the crank/rods lightened but a full balance always works well ! got mine done for less than Ł150

who done that jay .

did you not have your pistons attached ?

am i not better off getting the flywheel etc done ?

pistons should be individually balanced,rods balanced end for end,flyhweel has to be attached with the clutch cover
teeside motor factors done mine cost 117.5 including the dreaded few years back

Pistons as said are weighted for lightest one, rods balanced end to end, then as a set, crank, pulley, clutch diaphragm, flywheel, basically anything that rotates directly from crank.
Lightening can work wonders on cossies as the flywheel is large enough and heavy enough for the QE2!!, it will accelerate so much better with a lighter flywheel.
I have every engine done, even had the odd one frozen(not popular here in uk) it really does make a difference that you will feel and notice, depending on how bad it was to start with, balance wise cossies are not great in std factory form.
If only doing 1 job though it would have to be flywheel lightening for bang per buck.
It will rev a lot easier feel more eager and be smoother when all done properly.

tabetha what kind of weight can you remove from the flywheel or would you recomend buying one that has already been done.seen one on ebay that looks a nice bit of kit.
cheers james

Personally for the cost I would mod the std one by lightening, bearing in mind the weight is there for a reason to start with, that of a smooth engine, though to be honest I have never really noticed any lumpiness, but you can feel the need for just a few hndred more revs when pulling away quickly as there is less flywheel inertia effect, other than that no downsides.
I would say lightening would cost around Ł45, and think the std flywheel is around 10 lbs, these can certainly be taken to 6/7 lbs.
It may not sound a lot but the point is it is not having to be accelerated, so will have a much larger effect than you'd imagine.

Have a chat with this guy he is very very good http://www.vibrationfree.co.uk/motorsport.htm

According to th ebloke in Burton when my brotehr went in there is no point at all in lightening and balancing the bottom end as it can't rev and will run crap. Funny, mine's been done and doesn't have either of those issues

think ill give amac a ring , as there closer ,

wouldnt touch tmf

what you have done there bud ,

what the prices like ?

I think you have your lbs and kgs mixed up. 6lbs is under 3kg!

YB flywhel is actually closer to 10 kg.

Lightening stock cast flywheels can be dangerous you are far better off buying a purposely designed lightweight billet flywheel like this.

jacko

the fidenza ones are spot on

like you just happen to sell doug

how much for a cossie flywheel fella #

iTrader: (1)

beef, my bottom end was already lightened and balanced, it was checked and found to be spot on.

yes I do recommend them, my engine is the quietest pinto I have ever heard running bar the induction noise that you get with twin 48's lol

steve
