Newer 16 GPM pump developed slight leak

[gzecc]

I have developed a slight leak at the back of the hydraulic pump, where the screws enter. Is there possibly too much pressure or just bad manufacturing practices? Should I tighten up on the screw? Any experience with this?

See if you can find a torque spec for the bolts and check them.

I looked on line can not find anything. Any help would be appreciated. Its a speeco 16 gpm. < 1yr old.
Just sent an email to Speeco.

Tighten them. Even without the torque specs get them tight. Screws, bolts will loosen. If it does it again use some thread lock.

Got a response from Speeco, said tightening them won't work. He suggested getting another. Of course its out of warantee. Now every 100 hours I need to by a new pump? Products are really crap now.

I would tighten them up. What have you got to lose?

You can try to tighten them up, but I doubt that they are loose. They really aren't a repairable item either. If I remember correctly, those are the aluminum body style pumps? I have never dealt with those. The cast versions are what I seek (what can I say, I am old school). Haven't had any issues with those and my big boy has quite a few hours on it.

I like Haldex:

How bad is the leak? Just wet, or dripping?
Are you sure it is the end cover or maybe from around the check or unloading cartridges (if two stage) then can replace orings

Tighten them anyway, nothing to lose.
Or, remove end cover and see if oring or gasket is pinched or partially extruded.

But if just wet I would put rag under it and some rubber over it to protect operator if it did spray and run it. Then pull it down over off season.

Kevin - ya think a successful rebuild can be done on that unit? I guess if it is just o-rings, why not.

Not a RB just checking the leak.
Havent seen rebuild parts kits avail
Shaft seals probably avail at seal & bearing houses.
Not much else is fixable. Espec if it is alum body.
I am only thinking if rear cover seal leaks, pull it off and see.
But if it is just barely wet I would not stir up problems.
Depends on what a homeowner describes as 'leaking'
