Hi,

 

Can someone advise me of the best way to free up spindles and butterflies. I have a set that are well and truly seized.

 

Thanks,

 

Colin

Heat, heat, heat......

Than MOS2 oil to the bearings and try to turn the spindle.

Unbolt the throttle plates and again turn the spindle to

have the plates rectangular and remove them with a plier.

At last heat again and the apindle out with the help of more oil.

When throttle plates are out the spindles are very easy to break.

Great care must be taken, better more heat than more force and

between heatin let cool down with oil.......

Hi Colin,

Boil in saucepan of water for 15minutes. Lubricate with light oil and try to get some movement with gentle hand pressure.

If no joy, repeat.

Freed off a set a couple of weeks ago using this method.

Can't take the credit for this, comes off Utube

Cheers

Peter

Probably your best bet or soak them in a bucket of diesel for a few days.

Soaked mine for  two days in paraffin. No change.

Boil them. You won't regret it.

If the worst comes to the worst you can still  send them to k raven smith.

Cheers

Peter
