Vicon RF 135 sprocket & bearing removal.

[Treg]

Before I use excessive force on getting the sprocket off, is there a right way to remove the bolt then sprocket?
The bolt has thrown me as I'd assumed they all had circlips holding on the sprockets.

Bolt will be standard way, if it’s splined on then crack on. Top roller etc will be on an offset cam though

Brilliant, thank you.

Which roller is it? I know a bit more about 235s than 135s but not a lot of main differences

It's the main drive roller at the very bottom, first roller in the chamber.
I have managed to print of a parts list and blown up picture from Vicon online which helps.

If it’s a main drive with twin sprocket it’s guaranteed eccentric cam, the bottom roller when you open the door is eccentric cam aswell as is the top roller. Make up a solid ish bar with two M16 bolts welded on to fit tightish inbetween two opposite teeth and bolt it on, unequal angle inbetween the two rollers and give the bar a whack in opposite direction to normal rotation.

It's the first roller as the grass enters the chamber it has extra grips on the roller to help feed grass in the chamber, single sprocket.
By Vicons picture , bolt , washer, ring then sprocket on splined shaft so really hoping it's not a eccentric cam , vaguely remember doing one on my Deutz years ago which was a pain.

The parts book may not be right because there was an update to the rollers at some point and the baler could've had rollers replaced.
Not sure when the update was but our 1999 spec Deutz MP130 had splines on the rollers. Had to replace the bottom roller on the back door after the bolt came loose and the splines were damaged and the replacement roller and sprocket had the eccentric cam.

Our old deutz was spines. Got the lend of the eccentric came roller once. Balls of a thing. as splines wore we got them machined to take a key and a taper lock sprocket. The double drive rollers got 12mm cap head shear bolts to transmit the drive to the roller.
