You’ll need to drop the Bevelbox and swingarm off. It’s not a huge job. We’d do it in a day or less but we have a lot of experience. If you haven’t already done it the swingarm bearings and shock linkages will need greasing and don’t be surprised if they need replacement. I’d have at lest the swingarm bearings on hand. If the linkage bearings are shot it’s cheaper, or was, to buy a new double conrod than all the individual bearings, pins, seals etc.
