I was reading through these posts and this caught my eye. Do you mean that during the run of 8000 parts you had 20 service calls on the Servo 300? In other words an average of 400 pushes per service call?
Surely not!
Also to solve your sliding past the push point why not push to a stop? We have several shop-built hydraulic barfeeds that work this way. They did not cost us 6 grand apiece and they do a lot more than 400 pushes before needing servicing.
An open mind is a virtue...so long as all the common sense has not leaked out.
