Filling Hydro on MF 1655/1855

2 weeks ago I posted that I have found a faster and easier way to fill the hydro on a Sundstrand Hydro.

This may work for others but for those of you with a MF 1655 / 1855 here goes.

Remove the plastic tunnel cover over the driveshaft

Install a new oil filter filled with oil

Remove the return line from the spool valve including its elbow fitting
