Hi folks, I have just taken apart my hayter harrier pro to service the roller (I have never done anything like this before on mowers but restore cars so am quite practical).

I've installed new bearings on the end of the roller and new sprockets but upon reassembly I have noticed ALOT of sideways play where the rollers are sliding on the shaft...

Can anyone advise if I should/can shim up the gap or is there something else wrong with it?

Many thanks
