it is an Honor pump, 2GG9U22R Pump, Gear, 1.31 C.I./ 2-Bolt 'A' mount, #16 SAE In / #12 SAE Out, 3/4 x3/16 Keyed Shaft x 2" Long, CW Rotation. This is what was suggested by the customer service rep at Honor Pumps down in Corpus Christie, TX http://www.honorpumps.com/ I bought from them because the original was an Honor. The rep said that it should give me a little more than than 18 gpm. I don't have an indoor place to work on the loader. We had snow last night and everything was slop this morning, so no work done today. tomorrow looks like good weather.
