Feb 21, 2010 Anyone know where I can get a schematic for the hydraulic control valve for my Iseki TX1500F?

I have a manual but it only shows the unit as a whole.The part numbers and item numbers are in English.Hello everyone, I'm new to the forum - looking for info/experience on Iseki TL1900 or equivalent 4WD tractors. I'm in need of an operator's or workshop manual and any info or experience of anyone ever having repaired a seized rear linkage.Everything on the tractor works great apart from the main height adjustment arm on the rear linkage. The locking knob by the seat appears seized as does the height adjustment lever to the right of the seat. Picture just for reference. Any help would be greatly appreciated.

Japanese import so unlikely to find any manuals (or spares) for that specific model however a very similar one came in to the UK - cant recall exactly but TE3210 rings a bell, unless you find one breaking for spares you will need to cross reference against such models as and when.As its imported i'd wager that the lift cylinder or other internal part is simply rusted up (paddy field tractors / been stood up on dockside for years), a short sharp shock can do the trick. Otherwise top cover off job. Thanks for those comments. I'd found out it was an import - it has the common Isuzu 3AF1 engine so should be able to get service bits for it. It doesn't really need any other parts, as such. I have been trying to cross reference but it seems that even information for UK models is limited.I'll keep looking. Ransomes Jacobson were helpful, they are looking to send me a manual for another similar model.

Yes, I think something is seized with the main height arms because the lock knob is well and truly solid and the side lever mechanism is connected to the rear end via a cable but there is absolutely no movement in it. I'll whip the rotorvator off and strip the linkage arms. Is there a top cover to the rear end under the seat/tinwork? Update - I've managed to obtain the operator's and service manuals for the TE3210 from Ransomes Jacobsen. Jason, the tractors are very similar, you were right.Not quite the same but this gives me all of the info I need re stripping the rear lifting mechanism and valves. I've also tracked down the details of the relevant service kits - just need to physically measure my filters to confirm they are correct. Going to service the tractor, use it until October and then investigate and recommission for Spring.

Right, rotorvator is off. Had a feel of the rear arms and they were free. Started her up and played with the levers, nothing.So I looked at the push arm itself and the levers aren't connected up properly - the push arm is a little stiff but working.

So I moved the push arm by hand and the linkage works up and down perfectly. The speed valve is still seized solid still though. As I say, I'll strip her down this winter and make sure everything is serviced. Overjoyed that the hydraulics are all OK though. Rom Flash Tool Mk8081.Also flipped the rear wheels to make her a bit wider track.

Love the little tractor. Thanks for everyone's help. Much appreciated.

Q: I’m having trouble with my tractor loader, how can I determine what the problem is?A: Below is a loader drift test along with some information on loader valve trouble shooting.FIELD LOADER DRIFT DOWN TESTS1) Observe all safety precautions. Do not loosen pressurized lines.

Stay dear of loaded members of front end loader. Only an experienced hydraulic technician should work on the system.2) Make sure all fittings are tight and not leaking. Make sure that there is no external leakage from the valve or cylinders.3) Make sure that there is adequate hydraulic fluid in the reservoir.4) With the boom and bucket positioned so that there is no pressure in the hydraulic lines, tee a pressure gage into the rod end hydraulic line on the boom cylinders and a second pressure gage into the base end hydraulic line on the boom cylinders.5) Cycle the boom cylinders to full extend and then full retract a minimum of 5 times to expel any air in the system.

The cylinders should be cycled with the engine near maximum rpm. The bucket should not be loaded during cycling.6) Leakage test for the boom cylinders/spool.Place a load in the bucket that induces a pressure reading in the boom cylinder base end of approximately 1000 psi. Raise to approximately mid-stroke. After a short period of time note the pressure on the rod end side of the boom cylinders. It should be near zero and not increasing. If it is not near zero or is increasing, oil is leaking past one or both of the boom cylinder piston seals and the cylinders need to be repaired or replaced.7) If the boom rod end pressure remains low, use a marking pen to mark a line on the cylinder rod 10 inches away from the cylinder gland.After a set period of time measure the distance between the line and the gland and subtract the distance from 10 to determine how much the cylinder has retracted.

Using the boom cylinder bore diameter, calculate the area of the bore in square inches. Take the area of the bore times the number of inches the cylinder has retracted and divide this product by the time between measurements to determine the leakage rate per cylinder in ins/min. Since there are two cylinders, take this number times two for the leakage rate of the boom spool of the valve. Contact the factory to see if this rate exceeds the allowable rate.8) Leakage test for the bucket cylinders/spool.With the boom and bucket positioned so that there is no pressure in the hydraulic lines, tee a pressure gage into the rod end hydraulic line on the bucket cylinders.

Cycle the bucket cylinders to full extend and then full retract a minimum of 5 times to expel any air in the system. The cylinders should be cycled with the engine near maximum rpm. The bucket should not be loaded during cycling.9) With the bucket on the ground, roll the bucket down slightly, pressurizing the base end of the bucket cylinder and reducing the weight on the front tires of the tractor.After a short period of time note the pressure on the rod end side of the bucket cylinders. It should be near zero and not increasing.

If it is not near zero or is increasing, oil is leaking past one or both of the bucket cylinder piston seals and the cylinders need to be repaired or replaced.10) If the bucket rod end presure remains low check for bucket spool leakage in the valve.With the bucket lip approximately level and on the ground, place a load in the bucket and raise the boom slightly off the ground. The load should be adjusted so that there is a bucket cylinder rod end pressure reading of approximately 1000 psi. Place a mark on the cylinder rod 1 inch away from the cylinder gland. After a set period of time measure the distance from the gland to the mark and subtract 1 inch to determine how much the cylinder has extended. Using the bucket cylinder rod diameter, calculate the area of the rod in square inches and, using the bucket cylinder bore diameter, calculate the area of the bore then subtract the rod area.

Take the result of the subtraction times the number of inches the cylinder has extended and divide this product by the time between measurements to determine the leakage rate per cylinder in in3/min. If there are two cylinders, take this number times two for the leakage rate of the bucket spool of the valve. Contact the factory to see if this rate exceeds the allowable rate.LOADER VALVE TROUBLE SHOOTING1) External LeakageClean all dirt and oil off the exterior of the valve. Cycle the valve a few times to determine the source of the oil leak.A. If the external leakage is coming from the ports, remove the fitting, check for any damage to the spot face sealing surface or contamination. Replace fitting sealing washer and torque fitting to proper torque.B.

If external leakage is coming out from the spools on the handle end of the body or is coming out from the spring end caps, replace the spool oring seals as outlined in the valve assembly breakdown.2) When moving the control lever to move a cylinder, the cylinder moves in the opposite direction before moving in the correct direction.A. Air in the cylinders. With the bucket unloaded, cycle the cylinders to full extend and to full retract a number of times. This should be done with the engine near maximum rpm.B. Load check not functioning. With the boom and the bucket on the ground and the engine off, use the handle to move the spools in then out. Remove the load check plug, spring and poppet.

Inspect the seat and the poppet for any damage. Inspect for any contamination in the cavity.3) Loader won't lift the load or is slow.A. Load exceeds the capacity of loader.

Reduce load.B. Pressure setting of the relief is incorrect.

Adjust relief per tractor recommendations.C. Pump is not functioning correctly.D. Spools in valve are not being fully shifted — check linkages on joystick.4) System runs hot.Check to see if oil is going over relief valve during use of the loader.5) During use, cylinders become 'spongy' or allow some spring like movement.A. Air in the cylinders. The air can be purged by cycling the cylinders to full extend and to full retract a number of times. This should be done with the engine near maximum rpm and with the bucket unloaded.

The reservoir should also be checked to see that there is adequate hydraulic oil.B.Cavitation. When lowering the boom or rolling out the bucket when it is loaded, the oil supply may not be adequate to keep up with the cylinder movement. The engine may need to be run at a higher rpm or one way restrictors may be needed in the boom base end hydraulic line or the bucket rod end hydraulic line.
