This is a very old thread, but my guess is the respondents are still around (hoping so). Just wondering - my TS manual in the 'Performance mods' section at the back suggests doing the following so as to allow removal of the metal oil tank:
- remove cable from pump and wire the pump lever at 'second notch'
- swap the oil line to the manifold with the one to the LH bearing, and vice versa
- use premix.
I would have guessed the goal is to end up with LH bearing getting pumped oil, but no oil into manifold/premix. So, given my understanding that the flow rate to the bearing is fixed and not dependent on pump opening, I would have thought you could:
- remove cable from pump
- disconnect the manifold oil line and stop up outlet for this at pump and at manifold
- use premix.
That way, the bearing keeps getting its fixed oil flow, and can use premix. The only variation would be to put the bearing oil line on the manifold oil line outlet and connect that to the bearing (and plug up the bearing line outlet), with lever at second notch, for more oil to bearing?
