@lohanimal I have been instrumental in having a rethink attended to for the TTS 8000 Spindle Bearing Bushes.
I have donated a TTS 8000 to support the investigations undertaken and enable dimensions to be taken for New Bush Sleeves to be used within the Bearing Housing.
These New Parts are made from Torlon.
A New Sump Plug is also produced for the Base of the Housing/Pressed Metal Bowl, that has a machining that enables a selection of Thrust Pads to be used, in my case Torlon again.
Another TTS 8000 Owner who has adopted these same methods, as well as extend on them, has also discovered a simple method to retain lubricant in the Pressed Metal Bowl. This has been in constant use with an oil lubricant since the method was discovered with no leaching of a thin lubricant occurring.
I have a selection of Bushes at hand, produced to suit one of my owned TTS 800's Bearing Housing Inner Wall and Spindle Diameters.
The Bushes when seated in the housing will require a Final Hand Ream with a Reamer Tool.
If you would like to try this out let me know, I have a demonstration Instructional on fitting the Bushes from the Engineer who produced the Bushes, this can be sent to your email.
If satisfied with the info' on fitting and the interest still remains, I can send on a few Bushes to yourself.
What has been learnt through individual taking on this modification, is that in one case the Interference Fit Ball at the base of the Spindle had been discovered with a noticeable scribing to the surface. It is a reasonable easy fix and is worth checking for when the part is in hand. I have seen this condition reported on over the years on bearings being serviced on Long-Term usage TT's, it is aways worth a check, or request for a check, when a Bearing is being stripped down.
