More info on Hydro Filters

Recommended Posts

To all, After reading all responses to the various posts of mine and others I'd like to put my 2 cents back into the pot. Quoted from the Simplicity Service Manual: TP-500-0504-01-PM-SA (1997) Page 1-4: Hydro Filter 25 Micron. Page 2-2, Figure 65: Filter is between the sump and charge pump. The Hydro Filter operates under suction from the charge pump, TOTALLY DIFFERENT from an Oil Filter which is on the pressure side of an engine. To advise members that an oil filter is an acceptable substitute may not be a good idea, unless the filter grid size and flow ratings under suction are compared. Also add to that the additional restriction of the anti drainback valve some filters have. I'm not looking to bash anyone, just applying what I know (BSME, EIT) to the problem with my new tractor. I for one will use the OEM filter($10 from Jacks Small Engines). Happy (Hydro) tractoring everyone.

I agree about using the OEM filter. If it was something I had to do more than once a year, I might put some effort into finding a replacement. But, for a once a year change I would rather have the piece of mind.

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
