Hi all,
I have a massey 135 which I put a new hydraulic pump on about 4 months ago, she will work fine on the log splitter but will not lift weight on the 3 point linkage. It will lift my link box empty but as soon as I add weight it drops to the ground. So far I have checked the following and all seems to be okay:

Side cover removed & checked fingers are in correct place as well as cricket bale still in situ.
No water in oil - oil is only four months old and looks as new as the day it went in.
Removed hydraulic cover cap to check stand pipe washers - all well and oil is horsing out of the stand pipe with plenty of pressure.

I believe it means I am going to need to remove the top cover as this is the only place i think there may be an issue.

Any assistance or hints would be greatly appreciated
Thanks
Ga

There is up and down movement as well as side to side but no in and out movement on the top link, it is fixed solid

shot in the dark from someone with ZERO knowledge of that tractor....possible air bound somewhere affecting ONLY that movement???

That's a good possibility but how I check it or push the air through I have no idea

Those old MFs are not airtight so I wouldn't worry about it.

You are using the position control?

Bought a fully restored Ford tractor about 40 years ago. Everything worked fine except it could not lift my brushcutter. Returned it in exchange for a MF which was very good. Regret not holding on to that (Model N, I think about a 1950 build).

Yeah I am, I've since tried disconnecting the top link and just using the arms to lift and that's no problem and stay up so must have an issue in either the draft controll or top lid somewhere 🤔
