NEW XR4145C with Issue

[SmurfOperator]

These tractors definitely like higher RPMs but you will still have some flop. I ended up installing a higher flow pump, was a little expensive but well worth it in my opinion. Much better cycle times on the loader and flop is pretty much nonexistent now. Got it from deplorablediesel.com. Tried to find a cheaper option but looks like they are the only company offering a pump upgrade at this time. Pretty easy install, only thing special you need is a pretty big wrench for the banjo bolt and a pressure gauge to verify your relief valve is set correctly. Took me just over an hour for the full job.

Holy cow that is one expensive pump. Three times the cost of the factory pump and you gain 4cc. Not sure how deplorable diesel can charge that much.

Yea, there was some sticker shock for sure but I wanted a little more flow and couldn't find anybody that had a compatible pump. I went as far as to pull my pump and take it into a couple hydraulic shops, they said it has a non standard shaft and couldn't match anything up. My guess they are having them custom manufactured but aren't ordering them in the kind of volume that would get the price point down. I love the tractor but the loader cycle times were just a little too slow, that extra 4cc made a huge difference. A less expensive alternative would have been nice but I'm satisfied with the results.

Good to know that you are very happy with it. I'd guess that it is Italian or European spec pump since most of the valves are Italian on the tractor.

Are you able to read any of the manufacturer numbers of the old pump?

No other numbers on it. Has the LS part number, serial number and a made in Korea stamp.

I looked at mine and Joyang is the manufacturer. They are a pretty big manufacturer with Kioti and LS as two customers.

Did you install the adjustable flow restrictor in the correct hose? It shouldn't affect the curl up function at all. Since I installed the restrictor I haven't had the bucket flop condition again. I believe mine is set to position 4 on the adjustment.

I'm not certain exactly what LS models line up to what New Holland models. Does your New Holland Have the Shibaura engine or the LS engine? I'm curious if the LS part number is the same as on your New Holland. If New Holland uses a different part number it may open up more cross reference options.

You seem pretty informed so are probably already aware LS is now using the same engine/hydraulic pump... across several different models and adjusting the computer software to control the engine output. You have the same pump that can be found on an XG3135 powering an XR4155. The 12cc pump is probably just right for the XG and for most people works well enough on the XR3100/XR4100. In my opinion the XR3100s should come stock with a 15cc pump and the XR4100s should come stock with the 16cc pump. Don't get me wrong, I'm extremely happy with the 16cc on my XR3135 however I think the loader now moves just a touch too fast for some less experienced operators.

The 2017 and up Boomers are the current LS XR31xx/XR41xx tractors so it's the LS engine. A Boomer 35/40 is a XR3135/40 and the Boomer 45-55 is the XR4145-55. The only difference I can find is the HVAC controler in the cab is different style than the LS. Loader and subframe is also different. Regarding part numbers they are the same number except New Holland puts MT in front of it. Just my observation is that parts are easier to get from New Holland than LS but that is just one man's opinion.

Coming from the John Deere side the XR3135/40 align fairly well with the JD 3039/46R models and the 8.2 is close to what those use and seems like a common size in that frame size. Now the XR41xx is a larger frame and IMO should have a bigger pump. My only bark is the XR31xx 3pt lift is severely low compared to others in it's class. They should lift 2K 24 inches behind and the same can be said about the XR41xx in that their lift capacity is below the competition. If I were to change pumps I would say 14cc for the XR31xx and 16cc for the XR41xx.

That's good info. Wonder why they used a different HVAC controller of all things.

I've heard a few people have complaints about the hitch lift capacity on the XR3100. The heaviest attachment I run weighs about 800lb it hasn't been a concern for me personally.
