Found on Vintage Machinery - Great manual for an Oil Gear Pump brand - and trouble shooting surface grinding.

[Richard King 2]

I found this manual that has a great chapter on variable speed Oil Gear piston pumps, Trouble shooting issues when grinding and construction of Mattison grinders. All surface grinders are made the same, so it should help everyone grind better.

That takes me back, Rich; I ran one of those Mattison grinders, a 16 X 72" back in the shop of my apprenticeship, it had a badly worn plain bearing spindle, which I had to scrape in when we received a new part from Mattison. I made a dummy spindle and removed the machine's spindle and used the dummy spindle to do the marking, this machine did not have a pressure fed lube system for the spindle bearing, just a drip cup behind the wheel guard in a dirty environment, I relocated the drip cut where it was safe from contamination and easily seen and attended to. They used transformer oil rather than real spindle oil, not so good, I think.
