Jd410 hydraulic

Bk40 · Oct 8, 2016

I have a 84 John Deere 410b was wondering when I pick up main boom barely goes all the way up and the stabilizers won't pick up the machine I just bought any ideals?

Welcome to YT
I'd suggest to change hyd filters,check/clean suction screen which is located on RH side behind hyd filter cap. Then I'd suggest to check stand-by pressure which should be 2250 psi.

filter is full of metal put new filter in and changed oil but stil no hydraulic pressure. This machine has the piggy back pump so does the trans have to pump the oil to pump or does the piggy back pump take care of that the trans works fine

Tx Jim · Nov 3, 2016

What are you referring to as a piggyback pump? 410B has a closed-center frt pump that is supplied oil by a trans pump very similar to many JD ag tractors. According to Tratordata stand-by pressure should be 2500 psi. Check for hyd components that are hotter than other hyd components utilizing a laser thermometer.

Odds are somebody used the tractor without service until it quit working . The metal is probably brake disk material due to the friction material crumbling away and allowing metal to metal contact .
It maybe time to consider getting rid of or scrapping the tractor .

t is a John Deere 410 b backhoe loader the transmission has no lines coming from it the hydraulic pump is hooked to the rearmed motor trans then a driveshaft than reared. Think we are talking about two different machines

how can the rearend pump fluid if the drive shaft turns the machine will move so I don't see how there is a pump in there to supply the main pump

If the filter is full of metal it's not good . The only 410B I can find is an industrial tractor with a loader and backhoe .

Probably related to the 1640/1840/2350 or similar utility tractors.

es it's a industrialbackhoe loader not a utility tractor

Please excuse my mistake as my knowledge of JD ind tractors is very limited. You're correct on piggyback pump(key 26) which must supply oil to ""piston pump which can't suck oil"".

Did you ever check frt pump stand-by pressure & gpm flow?

Bk40 · Nov 4, 2016

i appreciate any help. I checked the pressure at the curl on the tractor the most is four hundred if I slam the bucket it went to a thousand once but while the bucket is moving zero

Tx Jim · Nov 5, 2016

Sounds as if system pressure is way too low. Check for excessive heat in the hyd components utilizing a laser thermometer. Excessive heat would indicate an internal hyd leak.

Bk40 · Nov 5, 2016

already did nothing really too different I bought the technically manual but does not tell how to check the destroyer valve so going to call aid today and see about any info on it but I personally feel the pump is fried.

Tx Jim · Nov 5, 2016

What would you like to know about de-stroking valve? Does your tractor have manual or electric DS valve? With manual valve screwed in is de-stroking(stop pumping) and out allows pump to build pressure.

KEEP IN MIND many frt hyd pumps have been replaced only to determine that frt pump replaced was not the problem.

Have you checked to be sure hyd filter relief valve is seating??

Bk40 · Nov 5, 2016

have not checked the filter relief it has electric relief

Tx Jim · Nov 5, 2016

(quoted from post at 10:30:10 11/05/16) have not checked the filter relief it has electric relief

It may have an electric destroking valve in frt pump but I've never seen or heard of an electric controlled hyd filter relief valve.

buickanddeere · Nov 5, 2016

service manual calls those a "Charge Pump".

Bk40 · Nov 5, 2016

sorry yes ur correct electric destroyed valve stil trying to figure out there is a spring under the hydraulic filter but it isn't long enough to touch the filter either I'm missing pieces or someone who worked on tractor last time had extras
