eddeere Posted July 5, 2015 Share Posted July 5, 2015 The American Bocsh pump on my 673 according to the manual is oiled from the engine. There is a drain plug and filler neck with a screw on cap on the pump. What is this all about ? 1 Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted July 5, 2015 Share Posted July 5, 2015 That is a woodward governor. Quote glenn akers Link to comment Share on other sites More sharing options...
Vladislav Posted July 5, 2015 Share Posted July 5, 2015 From looking the pic your pump absolutely sure has its own oil bath. Separated from the engine, has the seal over the drive shaft in front.Looks generally the same as my American Bosch off Lanova. My manual tells true about it though.

Lmackattack Posted July 6, 2015 Share Posted July 6, 2015 pumps normally are oil supplied by a oil line comming off the engine or simply splash lubracated. they simply drain back into the engines crank case thru the timing cover. no need to drain the oil from them when you remove it.

eddeere Posted July 10, 2015 Author Share Posted July 10, 2015 I understand it is a woodward hydraulic governor. Has one oil line going to so it must drain thru the front like mentioned. What is the purpose of the drain plug and fill spout. Just wondering. Quote Link to comment Share on other sites More sharing options...

Vladislav Posted July 10, 2015 Share Posted July 10, 2015 You better check out the info for your pump.Because I know the only reason for those two spots in the pump.I myself is far from to be a great Mack fuel pump specialist but my book tells "fill the pump" and "drain it through the plug".Also I had a deal with German Bosch fuel pumps off Mercedes car of early 70's and they had separate oil bath. With fill neck and plug.Later models became connected to engine oil gallery and had no such stuff.

theakerstwo Posted July 10, 2015 Share Posted July 10, 2015 You can see the oil suppy hose under the rear of the pump and up to the back of it. Quote glenn akers Link to comment Share on other sites More sharing options...
