30 ton Crane Cargo block sheave pin -normalising

Recommended Posts

I have a  cargo block that has come to us for repairs.  The Sheave pin(axle) needs renewal.

Material specs as per drawing is: S45C-N.  The dia of pin is 135 mm & length 300 mm.  

Appreciate expert opinion from members, regarding sequence of work process.  

I intend to follow:  

1) Procure EN8 rod & rough machine to 135.5 mm dia.  

2) carry out normalising  

3) finish by cylindrical grinding to the final 135 mm dia( for fitment of bearings).

Please advise if above is alright.
