    Cockshutt 540 hydraulic question

    Thanks for all the tips, have set aside a bolt to remodel when I learned it wasn't on the usual parts list.

    Cockshutt 540 hydraulic question

    Here's the evidence of broken remote control lever linkage - now to see if Phil H. has it and a new gasket in stock.

    Cockshutt 540 hydraulic question

    Thanks for the replies and schematic. I removed and cleaned the male fittings, both ok under thumb pressure, one a little springier than the other. When I tried the control lever, now it's loose, feels unconnected, so nothing happened. Will have to see what's going on under the cover. Not...

    Cockshutt 540 hydraulic question

    In trying out a generic 2-way hydraulic cylinder on my Cockshutt 540, I found it didn't work at all until I switched hoses, side to side, whereupon when the control lever was moved backward the cylinder extended fully but wouldn't retract until the hoses were switched back. Pushing the lever...

    WD45 pump/PTO issues

    I wouldn't have guessed it'd be this long before having more info on the PTO gearbox, but the picture reveals plenty. All those pieces were retrieved from the bottom of the gearbox - top ones when we drained the oil, the bottom 4 after the gearbox was removed. Except for the gear tooth at very...

    WD45 pump/PTO issues

    Thanks again - and enjoyed your comment about longevity of those seals. Maybe the old designers suspected those would be way down the list of things regularly inspected.

    WD45 pump/PTO issues

    Thanks, DrA, for your followup comments, especially since they address my next question. That being, is it accurate to say that leaking from the higher pump reservoir to the transmission would stop and stabilize once both levels were equal? And if so, would there be adequate hydraulic fluid...

    WD45 pump/PTO issues

    Not the first comment I've heard to that effect, and worthy of consideration, especially when looking at the logistics of getting to the middle of that torque housing under the proverbial barnyard tree!

    WD45 pump/PTO issues

    Thanks, that does clarify the situation for me - I was way out in left field with regard to the hydraulic reservoir and pump pickup tube. It all became crystal clear when I re-watched a good you-tube video of seal restoration in a WD and finally realized the relationship between front and...

    WD45 pump/PTO issues

    Our 1955 WD 45, that my son uses on his small farm, has developed a couple new unfamiliar issues lately that I have yet to unearth all the mysteries of before taking things apart. The PTO has developed a persistent ticking from the area of the gearbox that sounds ominous and is, I've recently...

    Cockshutt 540 carburetor problem

    Belated follow-up to the carburetor issue, now successfully resolved after several disassemblies/reassemblies. At the end of which I was reminded that the old "measure it twice" axiom applies to float adjustments too, but one has to read the ruler correctly. Additionally, new parts aren't...

    Cockshutt 540 carburetor problem

    Thanks to all for your responses. The link to Mike's carbs prompted a search for Viton tipped needles, which led to several helpful comments, some from past YT threads. Turns out Viton has been widely used for 40 years or so, isn't any kind of rubber, and is nonreactive to ethanol, making the...

    Cockshutt 540 carburetor problem

    Several months ago I disassembled/cleaned the 540's carburetor (Zenith 68J8) due to persistent gas seep from drain in the bottom of intake tube, found a visible speck of dirt in one of the small jets, reassembled and started/ran normally. The leak persisted however and, thinking the float valve...

    Clutch throwout bearing carrier

    I have since learned that the key to removal of the throw out bearings, when the carrier is reusable, is to know that the spacer between the two bearings is integral with the carrier - both bearings cant come off the same end.

    Clutch throwout bearing carrier

    I've recently split my Cockshutt 540 to replace throwout bearings and assess other clutch parts for replacement. The yoke behind the rear throwout bearing that straddles the clutch shaft is very worn and the throwout bearing carrier has so far resisted efforts to remove bearings for replacement...
