Transmission strip-down 4
I read up on how to dismantle an H55F. There are videos on YT, but almost invariably these skip the difficult parts and show you the no-brainer stuff. The best thread I found, by far, was on IH8MUD of course. The author of this thread made his own puller tool and did a really nice job of dismantling the transmission with no press (though I was far less keen on his hammer-and-drift method of reassembly).
I got lucky on eBay and managed to pick up cheaply this very nice puller, a Kukko AR210-2, apparently good for an 8 tonne pull and a very high quality German-made tool. My initial plan Is to use it where I can, then make some thinner arms with pawls on to draw out the really tricky bearings. The Kukko has reversible arms with standard, right-angled tips on one end, and curved, sharp claws on the other to grab awkward shapes and grooves.
It easily pulls off the output shaft rear bearing...
...and the counter fifth gear/syncro ring/spline piece/shift sleeve/shift fork and shaft assembly.
Output shaft splines look pretty good, counter fifth needle bearing journal on the countershaft is dark and feels glazed, but does not look to be damaged.
For the next steps, I need access to both sides of the transmission, so it's off for a short drive into the living room.
