A bearing puller is also required if the crank chain sprocket is to be removed. Also the components to knock something up like this is a good idea if working under the car:
A big socket, some threaded rod and three nuts? As I had the bearing puller (not expensive) and a genuine bush puller I can't advise the costs.
I've not added the figures up accurately, and assuming you have a reasonable tool kit already, this job can be done for around
£250 including job specific tools.
Time to do the job
£???, well I spent more time waiting for bits and being held up by other jobs on the car etc etc than I did working on the car. Get everything together first. Then as a DIY job rolling around on the floor I would suggest starting Friday evening I would expect the car to be ready for Monday morning.
