polaris 350L -93 6x6 change sprocket

[doublee]

How do i change the sprocket on my 6x6? looks like i have to remove these huge bolts that seems to be 44.5mm (1-3/4"), is that the only way?

answer is that it is just to remove them, it is thin threaded so it is a bit tight and takes some time to get off.

Next problem i got was the bearing for the output shaft from the transmission, it is really stuck there and i have not gotten it of yet but i have destroyed the bearing and maybe also the plate holding it.
Does anyone know if the newer style bearing with holder plate fits?

to answer by own question, yes it does fit.
