dave mc Posted March 3, 2013 Share Posted March 3, 2013 The teeth on my ring gear are knackered so will be replacing my flywheel on my Mk2 Vitesse soon.Is there anything I need to be aware of when I do this, or is it simply a case of undoing the bolts and putting the new flywheel on and bolting up again? Will be doing the clutch at the same time. Quote Link to comment Share on other sites More sharing options...
dave mc Posted March 4, 2013 Author Share Posted March 4, 2013 Is there any balancing involved for example? Quote Link to comment Share on other sites More sharing options...
JensH Posted March 4, 2013 Share Posted March 4, 2013 Ideally you should have the complete crank, flywheel and clutch balanced. On my last rebuild (FD-engine) I was surprised how much the engine shop had to take off the flywheel to get it right. Don't know if you are changing only the flywheel though.

ferny Posted March 4, 2013 Share Posted March 4, 2013 Just swap it over. Unless you're going to balance everything else don't waste your time and money doing it to this. Quote Link to comment Share on other sites More sharing options...

Richard B Posted March 4, 2013 Share Posted March 4, 2013 Alternatively, keep your old flywheel and just have the ring gear replaced.Anout £20 for the ringear and you need someone with oxy-acetalene kit to heat it up for fitment. Quote Link to comment Share on other sites More sharing options...
piman Posted March 4, 2013 Share Posted March 4, 2013 Hello Richard, I agree about just replacing the ring gear, but not to heating it up, particularly with a flame as there is a danger of removing the hardening of the teeth. It is not necessary to heat the ring gear, it will fit cold. It is a bit fiddly but with a bench, a couple of G cramps to keep it level, it will tap on; just ensure the new ring is facing the correct way before starting.

dave mc Posted March 4, 2013 Author Share Posted March 4, 2013 We have oxyacetylene but the new ring gear is on a different flywheel which I was just hoping to swap over.How do I get the 'new' ring gear off the fly wheel its currently on?

MrSpeedy Posted March 5, 2013 Share Posted March 5, 2013 Simply heat the ring gear and it will fall off! Quote Link to comment Share on other sites More sharing options...
piman Posted March 6, 2013 Share Posted March 6, 2013 Hello Dave, the ring gear is a light interference fit, simply drive it off with a hammer and drift. Use the torch if you must but do not overheat, being relatively small section the teeth heat up quite quickly (depending on nozzle size) and will be softened. Personally I always do them cold.Alec Quote Link to comment Share on other sites More sharing options...
dave mc Posted March 6, 2013 Author Share Posted March 6, 2013 OK all. Thanks for the help. I'll do the rear oil seal at the same time. Quote Link to comment Share on other sites More sharing options...
