massey 2680 PTO wont turn off

[euroliner]

have a a MF 2680 PTO wont turn off , , just after removing the fuel tank to replace a corroded spool valve pipe and am now tempted to try and fix the PTO issue .......... any thoughts on this before i get a million bolts into plastic tubs

 

[masseybreaker]

do you mean the shaft is just turning on its own or still being driven ? ie if its connected to something does it drive it when it should be stopped

 

[Mursal]

Little brake band/shoe has worn away, if its freewheeling?
Not worth stripping for that, is it?
Consider putting a cover over the shaft when not in use, some use a small cut of pipe on a tidy bracket .........

 

[euroliner]

no its still being driven , will turn a diet feeder on tick over

 

[masseybreaker]

if you follow the lever down through the cab its attached to a valve on the righthand side plate where the spool valves are that must be stuck somehow i have some if you need a new one. unless one of the clutch plates in the pto pack has broken up and jammed it in drive

 

[Mursal]

Would you have a live axle that could be grafted into a 100 series Massey or what would fit?
Thanks .....................

More on this on the 550 pto thread

spool valve seems to be working fine pumping oil to the top link bracket when required ....... must be the clutch pack then

 

[Mursal]

Just check the lever on the side cover, not the spool valves themselves.
Hopefully the PTO valve is stuck "ON"

 

[euroliner]

No its def not the valve its pumping oil when the valves open and no oil when its off

 

[Mursal]

Feck ...............

remove that pipe, then remove the 8 bolts and the top link housing. this housing contains the brake so with it removed you should be able to turn the pto. you will probably find the brake surfaces scored and burnt if it has been trying to stop rotation with the pack driving.
