Chainsaw Repair

The day before you want to put in new bearings, put them in the freezer. Next day remove all plastic rubber and chainsaw goop from the cases. Preheat your wife's oven to 150-200°C (do this when she is not home) otherwise you won't get any for a month! Put the cases in for 20-30mins. Get a block of wood and remove the case halves one-at-a-time from the oven and tap them on the wood, the bearings will drop out, so too will the seals. Put the case halves back in the oven, get your bearings out of the freezer, take one case half out of the oven, set the bearing in the case and tap it on the block to seat the bearing. Set aside to cool.
