When I was driving it "felt OK" when shifting but since unit is out of car, it is now hard to really scrutinize it.
I kind of have a 10 ton press, i.e. a 12 ton log spliter, I can pull off the splitting head and just use the ram and some clever home made fixtures maybe.
Started opening things up and the first real issue is removing the front bearing. Have the two clip rings removed and the shaft and bearing can be slide out of cast about 1/4 inch. The shop manual shows a special tool the seems to attach to the grove on the bearing plus the long bolts to pull it off the input shaft. Not sure how to solve this yet. Maybe after I remove the rear plate and just rap the shaft from the front?
With the side cover off, the shifter forks do not seem excessively worn. With the forks removed I can slip the unit into each gear (1-2) and (3-4). They seem to snap into position. When in gear not just 2nd but each gear, if I grab input and output shaft and try to rotate them in opposite directions I notice that there is fair amount of play on the syncro? as I apply the twisting action on the shafts. They kind of cock sideways a little. Having nothing to compare to I do not know if this is normal, but guesting it is not. All the gears look very good, no obvious nicks/chips. The "syncros" seem to be an assembly made up of half dozen parts. A rebuild kit on Ecklers states that it includes syncro rings. Another kit on ebay talks about having syncro springs. If I look for just "syncros" for this transmission I do not get anything. Does the rebuild kits supply the wear parts that would fix syncrows?
Kind of feel that queasy feeling like when I was 10 and took my first watch apart.
