Slow fel

[guitarman]

My loader on my 2005 JM454 works fine plenty of power just operates slow any suggestions

 

[oosik]

How slow? Time from flat on the ground to full height?

 

[DLTTrekkers]

Clean filter and clean back of controlvalve

 

[guitarman]

Haven't cleaned the valve it takes a screw on filter which I replaced still slow

 

[DLTTrekkers]

Check if the lever have full travel when move in and out (up and down ) off controlevalve ? Dirt in the endcap ?

 

[guitarman]

Time is not terrible maybe 15 to 20 seconds which I can live with. Just know it could be quicker my son's JD 420 E is almost twice as fast. I know some of might be just peculiar to the Jinma.

 

[DLTTrekkers]

Engine revs does not help ?

 

[guitarman]

Yeah has full travel. Probably should check some of the lines

 

[guitarman]

Does move quicker when I throttle it up from idle

 

[DLTTrekkers]

Mape sure that lever has full travel or a cinck in a steelpipe or a brazed fitting that is olmost closed up

 

[guitarman]

Have checked lines as far as kinks or crimped all are fine.

 

[guitarman]

I got tractor with around 280 some hrs have just over 400 now has always been a little slow.

 

[DLTTrekkers]

Any brazed fittings ?

 

[guitarman]

I haven't found any all seem to be screw on, threaded fittings

 

[RNeumann]

Often the QDs will get a chunk of crap in them and slow things down. That is a “choke” point for debris. You have to pull them to inspect them.

Faster RPM means more flow from th pump. Are you sure there is a 菟roblem or is this particular loader on this particular tractor just designed to run this speed ?

 

[guitarman]

Unfortunately I think you may be right and it's just a peculiarity of a JM454

 

[guitarman]

Was out using yesterday after finding what was problem with it dying which turned out to be accumulated water in the main screw on filter going to have to install a separater. Anyway I ran loader up and down curled it even tip it back while lifting all worked fine just not real fast.

I suggest you buy two gauges. Put one on each side of the lift cylinders. You should have pressure on the lift side while lifting and no pressure on the return side. If you stop lifting and there is pressure on the return side there is an internal leak.

isn't there a hydraulic speed knob under your seat? or is that just for the 3 pt hitch?
