Wow. I've been working on anything within 2mm being good enough so that could be where I'm going wrong. I'm thinking that my homemade rigs are not good enough and I should invest in a proper good quality puller, preferably one I can use for other jobs on the bike like splitting the crankcase. I'm seeing 'harmonic balancer pullers' on ebay that look like they will do the job but all seem too cheap to be any good on a job like this. Can anyone recommend a quality tool that is likely to last? The Yamaha one is stupid money at 150 euros plus, especially as it only does one job.
