There's a lot of work listed there. Bore and bush guide head is a big job and probably almost half the money. They need cut for a thicker wear band on the piston since they're honing probably .020" out.

Those two things require a bit of a machinist to pull off. They also probably have a much slicker polishing setup than your average garage. They are probably better than good at getting the pump seat recut to seal and not bleed off.

Yes they're proud of that job, but not out of line in my opinion. They'll have over 10 hrs billed labor on it total.

You could take the barrel to anybody with a sunnen or engine hone that knows how to use it and get it cleaned up. That's not rocket appliances. The clearance issue that creates is the problem. Presses are already bad for unnecessary side load -> why you cly is scored. Having a sloppy piston would trash it again in a hurry. Hydraulics aren't nearly as tight tolerance as most people believe. Fitting a wear band is a plus/minus .005 job maybe .010. It's all stuff you could do on your lathe if you felt brave. You could get away without polishing the rod, it may just weep some.

Is this Tacoma Hydraulics?

All things considered, I don't believe they're trying to hornswoggle ya by that quote. Just an expensive field of work, and they're doing work for the mills where downtime is $100k+++/hr so a $1500 repack is nothing.

Well I called the boss today and chatted for a while , he went through what was worn on it. No surprise as its 73 years old. He reckons it`ll last for a long time yet with the repairs.
I got him down to 1200 cash so wtf I`ll rescue the old bugger.
Guess I know where my stimulus check is going.

That's still very reasonable money to be in a 75 ton press. And a real deal nice one too.  :cool2:

Got it back today and to correct my earlier post it`s a 50 tonner.

It held 2000lbs of pressure for 24hrs so it looks like it`s gunna work.

Looking good!

Now, go to Youtube, and spend a few hours on the "crushing stuff, or destroying things with presses" videos. Then post 'em up for us to watch!

How about just building a 100 ton press, none were available to buy.

New in 2007, still kicking with zero repairs.
