or for the cutting head.....take your pick to get the right one in the flail head section!

Took the rotor out and found play in the non drive side bearing, will get a set of bearings in and hopefully that will solve it.
I didn't realise that the bearing was shimmed to the head and 2 shims fell out when disassembling. I'm fairly sure I know which bolts they came from but not 100% sure, is there a way to know which require shims?
Silly mistake on my behalf.

Put back in the rotor and tighten the bolts fully on the non drive side with no shims. Turn the head so drive side is at top and if rotor isnt dead square with motor fit one or multiple shims as required to each required bolt

Do as @Greenhorn says, take your time & get it right, get it wrong & there is a good chance the motor shaft will snap off, no other option than a new motor then.
Had ours out earlier this week as needed new drive gears, then got a set of bearings & end plates while it was out & new front rubber. End plates turned out to be thicker so had to grind the hole mounts & shim back up to suit, expensive but should sort it for a while......I hope .

Here's the link to the correct procedure to shimming the rotor

Is it possible to get a manual online? The machine didn't come with a manual unfortunately.

if this thing will let me upload pictures I'll put them up, multicut manual says motor bolts torque to 52nm, flail and rotor bolts 203nm

Obviously the above manual is the copyright of Mcconnel, I doubt they'd mind me posting them up as a customer helping a fellow customer, if they are bothered by this then I'll delete them. For reference the part number for the 1.2 multicut flail head manual is 41571.29 and I'm sure easily obtained from any Mcconnel dealer.

It's all in post 21, above anyway.

Thanks for all the help! Won't get a chance to get back to it until next week so will let you know how I get on then.
Unfortunately our ground is that waterlogged I've basically all the ground that I can travel cut anyway.

Back at this, have got two new skf bearings, I'm right in thinking to pull the seal off the side with the grease nipple?
