Hi With regard to Three Point Classics in Brisbane, I have been in contact with them and will be sending the bevel gears to them next week.Providing I can get the bearings off!
They have done two m3w bevels. One with 100% success in noise reduction and the other approx 60% noise reduction.
The process used is old fashioned lapping where the gears are correctly aligned and run with abrasive compound to bed the two gears together . This creates a smoother surface and a kind of matched set. If nothing else reduces friction and runs cooler a tad. Better for the oil.
Hope to send next week so will be able to report back.
Since we are in NZ they are relatively close being in Brisbane. The gears are quite weighty!
Originally was going to send complete box as they disassemble and rebuild, but weight put me off. Have decided to DIY which will interesting as I am more of a muchanic!
I did see if could be done in NZ but no lapping machines left in this country. Must be a facility in USA somewhere
