Flywheel Lightening

[opticaltrigger 52]

Hi all,

Going to take the flywheel from the project car to the machine shop and get the clutch face checked out. While I'm at it I thought possibly loose a bit of weight off it to. Obviously it would need to remain structurally up to the job in hand though.

 

Anyway before I did that I thought I would just put it out there and check to see if any of you guys had any thoughts on it first. I've not lightened one of these before so I wondered if there are any pitfalls to look out for. Or even better if anyone had some photo's of one, showing the areas material is normally removed from.

 

All the best guy's

O.T.

If its a 1.9 8v engine you could fit a 1.6 flywheel which will save you a kilo . Any machine shop with a decent lathe could remove some weight from your flywheel but balancing it afterwards needs specialist equipment .

Having lightened flywheels in a former life-what you're paying for is the time taken to rebalance it-sometimes 5 mins sometimes you take ages. If you go daft you could have a billet alloy flywheel with your ring gear shrunk on and steel faceplate-you'd want a machine shop that's up for it though. Undoubtedly makes engine spin up faster (makes big difference on bikes) but if you already have a lumpy idle it will become far worse with a lightened flywheel-think about a steam traction engine with its big flywheel, it's there to keep engine turning from one cycle to next

Ps cheap way to balance is on knife edges-heavy point will always settle at bottom-you spin it until it stops in random places ie no heavy spots

Thanks for the input guy's. However decided against lightening it in the end and just had it refaced.

 

All the best
