after 6-7 hours of messing around with shimming, decided it’s too late now and CBF,
oiled all the shims and the black nylon gears with Super Lube
then put it back together with out the anti-reverse latch, pistons and what not,
test run performed with 7.4v checker battery.
at the moment it’s set to almost no play at all on bevel and spur gear, there is just tiny little bit of movement, sector gear seems to have no play at all with just 0.1 on one side
Initially there was some horrible grinding sound, turned out motor was too high,
free the adjustment screw and it goes away.
but i am no sure what noise it’s making now, if it’s just the gears engaging,
or some surface rubbing?
watched Low Guido’s vid, he mentioned “this is the sound you don’t want”,
but honestly i can’t really hear the difference = .=
PS: motor was the one that came with the faulty gen9,
appears to be fried as it’s really low speed even with no load,
so the lobbing gel issue mentioned by the seller was not the box, but a cooked motor
didn’t think of that tbh…
i am glad i got it though, much have i learned from owning this gen9,
which will be extremely helpful when all the parts for my ACR arrives
