Is there no possibility of getting a needle roller inner that wil fit ?
Hi Chris, if you are talking about the thin wall sleeves you can buy, we tried this but there is very little room to play with, given the spindles 9/16 diameter, and the needle rollers have the same ID, they are wide enough, but their OD means boring out the original bush size by around 2 mm. The time and expense of the needle roller conversion is very prohibitive, unless you have enough skill in operating a mill, it's not the boring out that's the issue, it's keeping everything in correct alignment. For those that wanted to the specs on the ball races for the eccentric replacements they are 32 mm OD x 20 mm ID x 7 mm width, and you can fit two side by side in each eye ( so 4 bearings needed in total) The stainless hat section sleeve that fits through the bearings, is basically the same as the ones TT made, but the center section that fits inside the bearings is 20 mm and a nice slide fit into same. This part plus the shim spacer washer that goes on the inside has a small shoulder so as to clamp the bearings, and allow some side clearance to clear the sides of the link eyes ( visible in the first photo's). Ok Roy, now to your question....It appears to have tossed the rear cylinders rod, and the remains had cracked the bottom center of the right side crankcase half. This was repaired years ago, and quite a good job done.....only the welding had distorted the joint face so that when together a 14 thou gap existed, and radiated from the oil filter housing to the gearbox partition wall. We had the face welded after local heating and controlled cooling, then remachined all the parting faces....this lost us around 15 to 20 thou through the center, so the liner spigots had to be redone, all gearbox internals readjusted to obtain running clearance.....Should have just bought some new cases.....Oh well, things we do........Greg.
