KiwiGF. The honing requires a precision honing machine. I have Sunnen hone that works great for this, a lot of automotive machine shops will have the machine for rod reconditioning and small engine cylinder honing, but they probably won't have the correct size hone, which isn't cheap.
That aside, here's the process:
1. Grind crank (done by a trusted specialist) - rod bearings to the appropriate oversize, TS main journal to where it just cleans up.
2. Extract the old TS main bearing.
3. Remove the bearing insert from the sleeve and replace with SAE 660 (high lead, also known as alloy 932) bronze. Alternatively, you can purchase undersized bearings from various retailers.
4. New insert is pressed with 0.003" interference and sized 0.005" undersize of the journal on the lathe.
5. Bearing assembly is pressed into the case (heat case).
6. Insert guide bushing into drive side bearing (I made one out of steel)
7. Assemble cases and hone bushing to .001" clearance. The hone passes through both the bearing and the guide bushing. The guide bushing will be honed along with the TS bearing, guaranteeing alignment.
I had some pictures, but, stupidly didn't back them up so they are gone along with my laptop that was stolen a couple of months ago. I'll be doing an A65 in the next month in the same way and will take some more pics.
Hope that helps.
