[928uk] releasing crankshaft pulley and harmonic balancer

[Jim West]

I made a simple pulling tool out of some unistrut I had and use the crank pulley bolt to draw the damper off

Also make sure when you replace the damper it’s the right way round.

I helped another owner out when he put his on backwards!

Seems odd, as usually it’s the harmonic balancer that takes some time and wriggling to get free. I’m hoping it really was the pulley, ‘cos at least that’s further from the oil seal.
