753 lift pump leaking

[Vintagecarlover]

I have a 753G that is leaking fluid from the lift pump seals pretty badly. Hasn’t effected the lift function just loosing fluid. Anyone able to point out how to change out the seals? Also would love a shop manual cheap or free. Thx for help in advance. Mark. Ps. If this is already documented somewhere a link to the thread is appreciated.

A lift pump generally referrers to the engine fuel pump, is that what you are talking about? or are you talking about the hydraulic pump that supplies power to lift the arms?
If it's the hydraulic pump, just where is it leaking?

Tazz, it's actually the hydro pump leaking from the top left hand side of the pump but is definitely TOP of the pump. Any links or manuals availability appreciated. Or any help at all? Thx. Mark

Tazza, yes sorry, hydro drive pump, not lift pump. It's leaking on top of the pump under the bracket which I think is where pinion shafts are. Any threads on the forum or any writeup on this repair? Also does anyone have a manual for sale or one I can copy for cheap? Thx Mark

Look up my profile and send me an email with your serial number, see if i have a manual that covers your machine,
As for the leak, if you are talking about the pintle shafts that the steering levers join on to, there are plates with 2 seals in them that stop oil leaking out. Fairly straight forward repair. Just takes time and new seals. One seal for the shaft, one seal that seals the plate to the pump body.
