Engine Install Problem!

a real simple bushing puller .....a tap just a little bigger than the shaft and a piece of all thread or a long thread bolt the same size......tap the bushing ,then run the bolt or all thread in and as it hits the end of the crank it will push the bushing up the bolt ...keep turning untill bushing is out.simple cheap and works every time .....
the tap you need is called a bottoming tap ...it has very little taper on the starting end...some times i just keep turning the tap also, it will do the same thing as long as the bushing comes out easy... taps break easy so be carefull doing it the last way.
