lots of time I find them upside down which makes them really hard to remove

remove snap rings holding sprockets to shafts.... note the sprockets are different and only go up one way

chain and sprockets removed main shaft removed just pull straight up

ok pry indetween shift fork and rooster comb to get the first shift fork out sorry I didnt get a pic
it will take alot of pressure but it will come
I know the proper way is to remove the roll pin but I end up fiddling around forever and sometimes cant get it out
after you get the first one out you can just rotate the rooster comb up and wiggle out the inner shift fork
then remove the roll pin and we will assemble it according to the manual

i can deal with that, but mine warped and got weak, so when they were in the little grooves they slip into, they spun around. this let my tailshaft move forward and backward and at highway speeds this blows ur seal.
believe me, iv been through 5 of those dam seals already. i got some new rings from the dealer tho so this friday im gonna tackle is and see if it holds.
if not im putting a hammer through the sob

remove the shifter detent and the range switch

wiggle out rooster comb it only will come out one way
save the oring and plastic ring that comes out the other side

take your stock snap ring to a bearing supplier and match it up with the snap rings that have the two eyelets they are a far superior ring we change them up all the time it is actually the fix for the NP241 output shaft snap ring failure

ok before we start re assembly lets change the trans output seal


remove the seal
