The stock cam gear is not heavy enough , like others have said . Ya need to step up to the 450 cam gear . Also check how much pressure your putting out , You should be around 1250 and not above like 1450 , these old systems were not really that high in pressure and they do not operate some of the newer implements of today that run higher pressure on smaller cylinder dia. If you are finding it hard to lift some things with the factory mounted cylinder don't try jacking up the pressures to do this as you end up trashing out the gear . If it won't lift with a two inch cylinder then go with a three if three don't get the job done then go to four , yep it will be a slower lift because your old pump may not be putting out the GPM's that it did when new . and at best 12 GPM's is new spec. on like a 400-450 and around 10 on 300 and 350.

It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
