Kabuto 3301 pressure measures low (1800 instead of 2300).

[bleeting]

I have a l3301, I needed about another 100 pounds lifting force to lift a bale I've started using comfortable. I went went to go shim the pressure up some, but it's only reading 1800 psi. The manual states it should be 2300 psi.

This seems far too low to be a factory error, so either the number I'm referencing is wrong, I'm somehow getting a bad reading, or something else.

I gave a 3k psi gauge hooked onto one of the quick couplers, than at full speed I am actuating that valve.

I hesitate to shim it up to correct pressure because something seems wrong.

Not sure why you don't trust the gauge... Other than "here" are you close to my location. I have a gauge if you want to borrow.

I went from 2250 to 2400 then bump to 2700 psi... yes, it is above the recommended psi.

PS. you might want to just tighten the nut down to see what you get... Also, Yes, I think a dealer could have it that far off.

I just can't see how anyone on here can tell you if your gauge is bad or not. The psi just wasn't set when the dealer but the loader on.

Some more info BTW, I shimmed it anyway, because YOLO as the kids say.

At the original pressure of 1800psi read, the lift force was 1521# just forward of the pins (with the frame of a fork attachment only) @ about 4' up. That's pretty close to rated capacity as I understand it, but I'm not sure if that is with or without bucket weight as I think the frame weighs a bit less.

The shims were originally 2.27mm thick. I went ahead and shimmed it to 2300psi, the new thickness was 3.94, after that the lift capacity went up to 1962#, same scenario as above.

So I think I should reach the conclusion the gauge is probably no good or somehow I am not reading it correctly.





If anyone is keeping track, for me that means each .334mm = 100 psi increase, and 88# lifting force per 100 psi. And the shop vac trick works perfect.

(I took the forks off after this, those bastards sap 200# of lifting potential)

I'min cFL, If my gauge is fubar, I'm probably at 2.7k - 2.8k right now. I'd love to leave it. I am handling a lot of double compressed alfalfa bales that range up to ~1200 pounds and I can only barely get any height with them since I grab them with tongs and only start to lift with the FEL 4' up.

I just can't see how anyone on here can tell you if your gauge is bad or not. The psi just wasn't set when the dealer but the loader on.

I wasn't asking if the gauge was bad, I already ordered a spare to be sure. I was more asking if anyone has seen such a low pressure or had any sort of alternative explanation to the simplest conclusion.

Mine was low from the start (also 3301). I read somewhere that they were set that way from the factory.

I hate to tell you how much the QA system is stealing from you in the amount of pounds you can lift... (pushing the load forward 4") From what I can see those forks are pretty "slim", you should be happy with only 200 pounds.

My L3200 (same as your L3301 minus tier 4 emissions) would get "1,200lbs" big square bales on my pallet forks to about 4' high. Given the weight of the forks & size of the bale sticking that far out I'm sure it was noticably over the 1,200lbs rating. I dont rememer the pressure when I checked, but it was well within range. Thought it was pushing 2,500psi. Needed the 5' rotary cutter on the back with several 50lbs bags of junk at the far back of the cutter to keep things sketchy as opposed to the back end off the ground & rolling. Rear tires were loaded too.

I understand that the animals have to be fed, I get that. But why over load the tractor pushing it to extremes? If this is something you will need to do with regularity get a bigger tractor.

About gauges most are more accurate at the middle of the scale. So if buying a new gauge a 5,000 lb. would be a good choice.

Well, no way I could live without the QA, so I'm just going to stick my fingers in my ears. And yea, that fork attachment/forks is the lightest I could find.

Yea, the "800#" pound rounds I buy are 550-600#, they are all full of crap. Moving palatalized fertilizer/concrete I think it was around 1100# before the FEL started to give up and couldn't lift it much above waist height, and it was also pretty tippy. I need to build a ballast box, I don't like using something like a drag harrow because it kills your maneuverability.

This wasn't the original plan, I needed something to handle sub 1k stuff, then these blocks came along and I can buy alfalfa for the same price as grass hay, and half he cost of the closest comparable nutrient hay, so I do. I'm not trying to take the tractor to the extreme, I just need around 100# more lift capacity.

I was helping a neighbor clear out a barn. They got a barn full of big bales, then promptly got rid of the goats because of health reasons. Helped him move 2 dozen big bales over a few months as he sold em off.
