    L2900 GST Shifting Problem

    Thanks! I may look there to see if the issue is discussed. -- The answer though is that there is nothing at all wrong with my tractor other than that the shop changed the fluid, refilling with UTD after the split. When cool, ~40F, this fluid is thick enough to delay shifting drastically. After a...

    L2900 GST Shifting Problem

    Im sorry. I hope you will be able to cope using your mental powers, experience, and imagination. We, both my wife and I, test drove the tractor. The degraded transmission operation stemming from some unknown Murphy attack during dealer reassembly is still identically present. We have initiated...

    L2900 GST Shifting Problem

    Got it. Thanks for the reply. I went to the dealer today. The senior mechanic, Warren, had adjusted the low pass valve to increase shift speed, and then left. He told them that it was operating correctly. Maybe it is now - I didnt test drive it because it was raining and pertinent contact people...

    L2900 GST Shifting Problem

    Hi. I have several Kubotas - none particularly modern - but all working fine until just recently. Then the ~ 1990's vintage L2900 I have had for 10 yrs had a circlip come loose inside that made it so that the PTO could not be disengaged. It is a known problem on this model. Kubota has an...

    How to measure hydraulic pressure?

    No. Pretty much the same Force fast or slow. A FULLY warmed system may lose some force/pressure at idle because internal system leakage of the hot thin fluid will cut into the low flow available - thus limiting the ability to build pressure and therefore force. Any system pumping enough to...

    Standing on Platform on FEL?

    I imagine that in lightly loaded lifts most hydraulic/leak/burst failures happen at end of travel. Lowering the relief valve setting temporarily should lessen the risk on a people lift.

    Hydraulic flow numbers

    With either given motor the lowering of torque with that motor as flow decreases is because flow has to supply both motor motion and leakage through the motor. If there were no leakage both of the motors would deliver their characteristic Torque -- ~1200 vs 1900ft-lb@ the 2500PSI relief setting...

    Hydraulic flow numbers

    This is probably with the hyd fluid fully warmed. The fluid is thus thinner allowing more bypass/leakage in the motor and preventing building good high pressure across the motor. You should be able to get near the full ~2300 ft-lb torque at the lower flows when the fluid is cool and thick. Itll...

    Air Compressor Performance

    Hi. I have an IR TS5 80Gal. I checked and it does 0-170PSI shutoff in 6m59s. Its a 10yr old original setup. The motor is 5HP, Service Factor 1.15. I saw that someone mentioned using engine oil in a compressor. I did this with no problem in single stage compressors but got a prompt surprise when...

    Tree cutting accident

    It would be interesting to figure out what proportion/combination of factors put you over this edge; Stale unrefreshed consciousness and skill, Unscrubbed 5 mo oxidation on the tires, Cool stiff rubber, Cool road surface. Doesnt take much of a wheel "skate" to set off the sphincter and freeze you.

    Duel, wheels

    Well, mostly/maybe, but a bunch of truths form different relationship in different situations. In cohesive consolidated earth the pressure to bite in is important. AGs generally have this but dual setups will diminish it somewhat -- likely enough on firm ground to sabotage the extra weight and...

    Quality of Hydraulic Fittings

    I exclusively use the Jic fitted double braid hoses from SC. They have a very high pressure rating. I have many in service and have never had a failure. My only complaint is that the outer sheath weather cracks from sunlight sooner than I like, allowing the steel braid to rust. I use BoeShield...

    Tire loses inflation when turning.

    36psi is a good pressure to prevent the likelihood of "de beading" or partial thereof during side load while turning - esp if you are using a loader. Inadequate pressure will allow the bead to "work"/move under load and its all downhill from there. You may be experiencing this - in which case...

    NX5510 - No hydraulics after filter and fluid change

    Maybe the filter seal is faulty and leaking enough air to prevent prime. :unsure: It doesnt take a lot to foil the suction side of the hydraulic system.
