    I have been searching for the numbers...  discovered tonight while using a flashlight - the differential is a Peerless 1323.  I have not been able to find the model of the hydro.   In looking on the Peerless site the info for this differential shows an Eaton hydro Model 7 or Model 11.  I am heading to their site later.   But this brought up  more questions 1)  what oil should be used in the differential.  I have the original owners manual (my mom bought this) and no mention of servicing the differential other than checking the level.   Then where is the drain plug for the hydro?  I thought it was the same oil for both units.  
    Owners manual shows the Multipurpose Hydro Oil (case lot) 1685516
     
    any help would be appreciated...

    Finally have had enough time to get back to work on this mower.
    The Hydro is an Eaton 7...  I now have their service manual available online and only have one issue.  I have drained the fluid and starting to put fresh fluid in.  According to their manual, you remove the vent plug then fill the reservoir with fresh fluid until the fluid runs out of the vent hole.  My problem is the oil once poured into the reservoir - it does not go into the transmission...  if it does, it is very very slow.  It will take a long time to fill the transmission at this rate...  Am I missing something? or is this normal.
     
    I have tried rotating the wheels and the input shaft but no measurable success.
     
    any suggestions??   and thanks to Jacks for having the parts to get this project back in the yard.
