Hydraulic pump weak

Is it possible that you missed the part where Chip said the CB306 is simply undersized for a loader-equipped TS254C ?

Yes, I did miss that. So that explains slow. I havnt gone back to check but I think he said the problem came on suddenly and the pump now gets hot. Could be it just wore out I guess.

The 306 is plenty for the 3 point alone, even with power steering. but is not too swift (literally) with the loader. we got 306s on our first load in 2003 and after koyker fitted the 160 loader for us, they recommended we ask the factory to fit a larger pump... the rest as they say... is history

Lakespirit.// Was it slow and weak from new with the original pump ?

I know what you mean.. all my ford loader tractors are 4gpm setups.. none too fast.. wouldn't want to use them in commercial applictions.. but for homeowner - powered wheelbarrow stuff.. they work great.

what are the breakout / full height lift specs on those machines anyway?

varies with loader manufacturer specs.

Leave the 15-40 in it forever , there is nothing wrong with using it (and i did say if your sure it is worn out and just want to give it a little pep). We in Australia use it in everything , truck and tractor transmissions , engines , hydraulics and all , some manufacturers recomend it , ive never heard of a complaint . We would not be able to change gears with a 90 weight in our gearboxes on cold mornings so we all use 15-40 and on hot days 10w hydraulic oil losses it's viscosity so we use it in the hydraulics , Caterpillar dozers use it from one end to the other .

Just how cold does it get in Australia that you need to use 15W40 oil in your hydraulic systems? Here in the mid-west of the good old USA temperatures get down to below freezing and I have never had a problem with the hydraulics in my KAMA 354.

You may need to read my post again , i said 15w40 is for our HOT days in hydraulics not for the cold , as 10w loses it's viscosity when under extreme heat . And as ive posted before in other threads , 15w40 should only be used in warm climates as it is a little thick in extreme cold . But on worn machinery it can help to get a little more work out of it before it is rebuilt or scrapped . Now i said we use it for GEARBOX'S in cold weather as im sure your trucking guys also do because 90 becomes too thick and slows the gears in the box too quickly making gearshifts troublesome .

I'd never put plain engine oil in a gear box.. no EP properties.. UTF would be a better choice at near the same viscosity..

The oil companies seem to think it's alright .

Yo lakespirit,
I was brousing around other Chinese tractor forums last night and I came across another "lakespirit" with the same tractor as yours and the same problem with slow hydraulics. I forgot to write down the name of this site but I would like to ask if you are the same "lakespirit"? This "lakespirit" posted that his father was monkeying around with "lakespirits" tractor and that the father tightened down something that should not have been tightened down. When this "lakespirit" corrected his father's error the hydraulics worked just fine. Are you this "lakespirit" or is this an amazing coincidence?
