How has your experience been since you installed this pump? Pros/cons or concerns? You've had it on longer than I so your feedback would be good.

I haven't had any issues, been supper happy with it so far. Aside from the loader speed the higher flow rate opens up your attachment options a bit. I just built a hydraulic auger for the quick attach to do some fence posts. So far so good.
I plan to upgrade the pump on my MT345he. The pump from deplorable is just way too expensive though. Seems like we should be able to find an off the shelf pump for this. The mount for the pump is a standard size, but I'm not sure the spline count is standard. I think I count 12 splines on the deplorable pump. Anybody know how many splines I should be looking for on the shaft? If nobody knows, I'll check when I do my 50hr service. The pump on my tractor is a Hema brand, but Hema doesn't have pumps on their website that match the numbers on my pump. They also don't appear to have any pumps at all with a 12 spline shaft. I suspect LS has had Hema make their pumps "special" so that we can't buy aftermarket pumps.

you sure it's 12? I thought I saw 13 spline pumps sae B at surplus center that look similar, just not sure about the rotation & fit & max psi specs all seem to be 3625 @ SC. Figured I'd wait till I have a project that would benefit from a 2.07 inch^3 size pump before I waste $200+.
I'm not sure it's 12. I'm asking at this point. The best I have to go off so far is the pic of the pump on deplorable's website. It's looks like 12 spline to me.
I agree it looks like an sae A or sae B pump. Rotation would probably have to be determined by removing the pump and turning the engine over. I think anything 3000+ max psi would be fine.
I was really hoping I could just find the stock pump on Hema's website. Then we'd know everything. No luck though. The numbers are really hard to read on my stock pump though. I can only read a few letters and numbers of the model #.
I just really hate having to take stuff apart to determine which parts I need.

Unfortunately, tractor manufacturers like to use proprietary pumps on their tractors. Even though it may totally look like an off the shelf pump, you may find later that the manufacturer decided to use 1 more or less spline on their pumps or just changing the mounting flange dimensions for something odd and specific to their use.
Even on Deplorable's website, they say: "High quality 10.6gpm pump custom manufactured exclusively for us."
That's why you often find crazy absurd prices on simple replacement pumps for tractors.

That "custom manufactured exclusively for us" is what tipped me off. I know I won't pay Deplorable's price. It's not even a nice pump. I'd buy it in an off count spline and machine it to what I need before I paid that price. It's less likely to be something odd and specific for their use and more likely to be so they can gouge you on the back end when you need parts. It's immoral. It's also a concern that people should have when buying a tractor like this. What happens when LS stops supplying this part? The tractor becomes a paperweight. When that happens, the LS name will be in the gutter. I smell greed.
I'll find out and report back.
It's possible that the pumps off the MT4 series tractors would work. They are a 9.9 gpm pump, which would probably help quite a bit. The suction side might be a different size though.

Looking at the parts list on the LS site, it looks like the high side connection on the mt4 series pump is a banjo style connection and the mt3 series has a threaded connection. Suction side looks the same though, but it probably wouldn't work.

Very good PCABE5
This is what makes tbn so great. Good write-up on the upgrade hydraulic Pump and install, plus a link provided to the outfit providing the pump and other useful items aimed at LS built tractors.....good stuff all around.
I was wondering about heat being an issue with the new high output pump but Looks like it may not be an issue.

It is a 12 spline shaft. Clockwise rotation.
I looked at the MT4 pump and initial thoughts were it would work but the pressure line would have to be modified which is not hard to do.
That's good to know. Thank you for the help.
Do you know if the MT4 pump has female threads as well as threaded bolt holes, or just bolt holes?
Or are you thinking you could adapt the threaded male fitting on the MT3 tractors to the banjo style on the MT4 pump?

I was never able to get my hands on one due to the crazy parts shortages. I believe that the pressure side is similar to the suction side of the power steering pump. Two bolts and a o-ring seal.
My thoughts were to get the MT4 pump and the section of pressure pipe that comes off the pump. The stock pressure pipe and the new pipe would be cut to length and accept a union to join them.

That's a good idea. I didn't realize you can use compression fittings on those steel lines. This sounds pretty easy. I'm going to have to do this if I can get ahold of a pump.
Wish I didn't have to go through a dealer for parts though... My closest dealer is 2 hrs away.
It's really a bummer they made it 12 spline. I would have gone with a 12gpm pump if I could use an off the shelf pump.

Yes you can use compression fittings. The tube will most likely be metric, so something like this will work perfectly. Doesn't even need flare.

Does the MT4 have a NH 'equivalent?' I've purchased several parts from the NH dealer (which is open on the weekends) or from online dealers such as Messick's. I havent kept up with what LS model is the same as NH. Just a thought.
