Well im home on a fri night and im about to install a new superblend layshaft bearing (the one from old britts) and im not sure which way to face the inner and outer bearing casings. They both have writing on them! Im pretty sure the outer goes facing the gears. but does the inner go towards the gears or towards the left side os the bike???

Thx tons!!!
 
Here is a not so easy to see pic, but if you save as and zoom in, you can see what markings are on the side facing the RHS of the bike

great!!! i got the outer bearing case, but what about the inner race??? does that face rhs of the bike too??? if so the inner bearing race flange should be to the Lhs side??? it locks in the inner race? thx
 
Keep the lettering on the same side---the inner race shoulder goes on the layshaft facing in or to the right.-----that way it will fit into the outer race when you insert the layshaft-----read the trans assembly notes on the OLD BRITTS site before you do anything----you can lay out all the parts and then start---very good assembly info.

ive read it over and over!!! i know he says keep them on the same side, but that puts all the lettering facing left side of bike!! and your example shows lettering facing rhs! sorry to be such a pain but, i want to get it right!!!
 
with the shoulder of the inner race to the right hand side next to the gears, it puts the writing towards the left hand side! is this correct?
 
It would depend on which side the lettering is on. On a FAG NJ203E M1 C3 which I have in front of me now----yes--the lettering would be facing left on both the inner and the outer race when it is installed. the shouldered inner race actually is free to float ---this is why you must check the end play and shim to about .005 thou.---In the picture on the OLD BRITTS site you can see the inner race on the end of the layshaft--the shoulder butted up against 4th gear "shoulder" side.

thats it!!! thx so much! i got the guage to check the play and the shims to adjust!!!! appreciate the help!!!! rob
 
All my top hat inner races were rather tight to slip onto lay shaft and keep in mind the AMC gbox needs no stinking gaskets for nothing so losing one or two may be most efficient way to tame end play.
 
Hey hotbot! interesting that you commented on that!!! I have no play at all which is weird! My layshaft bearing is pretty much flush to the case and snug!!! So i dont know where i lost some space. I am going to take the gears out and replace them again. any ideas you guys? when i put my inner cover on the layshafts is so snug it wont move at all. this is not good right? Its too tight!! cheers rob

"Pretty much flush" is not completely flush. When we are talking about shimming, (if needed (sometimes it's not)) we are talking about .005 to maybe .030 or a little more. So if you are not completely flush, you could bind.

Is the inner race seated all the way onto the shaft? Did the outer race go into the case smooth and straight or was it a bugger and possibly galled behind the face?

Just install the layshaft by itself in the case---then install the inner cover---check then----should be loose and spin easily----that is if the bushing in the end of the k/s shaft is in good shape----if still binding the bearing or inner race may not be seated completely.

yep got it!!! amazing! thx. Now to start on the electrical!!! oh brother....
 
Speaking about the KS side of layshaft bush binding, I put an oil spiral groove in mine, just in case. Also in the 2+1=3 sleeve shaft bushes as no oil can get in there while sitting still or in lower gears spinning. The oil ain't so much a lube as it is a need to carry off melt level heat.

How do you put that groove in there?
Does it go clockwise or counter clockwise?
 
I used a ball shaped bit on a dremel and as area don't really rotate much, as only turns a few times at human slow idle speed - I didn't give a thought to the spiral direction except as I'm L handed its likely backasswards from what's commonly done. Just cut a bit below surface and don't have to be pretty just nothing left proud of the surface and don't fret if runs away ans scratches up here and there. Peel's top fork bushes also done. But by far mostly needed in the two or better 3 sleeve bushes. Ugh I've had one KS bush so stuck up in there I had to cut it in half by dremel the hard way. Smarter mechanics come up with a puller from concrete studs. When closing up woth while to clear coat or pain the exposed steel stuff above oil level in the out cover area.

No one else asked, so I guess I am going to ask a stupid question, but what is all that green snot in that gearbox?

:?
