The lost motion accounts for about 1/2 inch, which to me is too much. I took the clutch rod and fork to a machinest and he cut the slop about in half (was 1 inch), said the other holes were about as close to correct without him bushing them. I know that the holes, etc add up, but without getting all new parts, which don't exist, I can't put it back in new condition. THe new sleeve is aftermarket, there is a little movement between the fork and the "nubs" on the sleeve. Shifts ok when the clutch pedal and the TA lever are disconnected, although I don't like that much free play (2 inches) in the main clutch. The gears grind when the rod is connected, when the TA is adjusted by the book, and also not by the book. Pilot bearing is new, the parts are clean. The main question is, if the engine clutch is disengaged, why do the gears clash with the (clutch pedal to TA lever) rod connected. I can't see inside the TA, but the TA clutch is visible and free when disengaged. It seems to me that the gears begin to turn when the TA is disengaged which happens when the engine clutch is disengaged -- that should be impossible. One thing I can't find a spec on is the gap between the TA clutch disk and the surface it contacts when disengaged. That gap is affected by the free play of the TA clutch linkage, which when set at the recommended space of 3/16" isn't much, but it is free. You say "gummed up". Admittedly I did not slide the pilot bearing onto the shaft to see how it fit before installing in the flywheel. That bearing is standard equipment on Hy-Capacity rebuilt clutches, and I think I would have noticed if the shaft was garfed up.

Today's Featured Article - A Lifetime of David Brown - by Samuel Kennedy. I was born in 1950 and reared on my family’s 100 acre farm. It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
