MX110 needs a tweak

How far can I safely tweak the pump on an MX110 to get a bit more hp out of it?

I understand that the engine is capable of a fair bit more power output but don't really want to destroy the gearbox by overloading it.

It's getting used on a 3000 gallon tanker and just needs a little bit more oomph on some hills.

Same back end up to the MX 135.Same engine continued into the 150 and 170 but beefier back end in these. A 3000g tanker is a big pull on 135hp let alone 110 don't you think?

Any of you lads in the hills have any diff trouble as they did not like over running used to give pinion bearings grief. And old 5140 upto 160 on shaft. Thick farmer just give it a quarter turn on the remap stud first Better on a dyno . Have you seen these yanks drag racing with diesel with these type of engines running 2500 hp but some serious mods

She pulls it quite well! I was considering filling the rear tyres with water to ballast her though.

Brill. How do I find the remap stud?

Our 5140 did the back diff in and was only doing 120 at the shaft. No heavy draft work, apparently they don't like a lot of road work. Would the MX110 have the same diff or was it uprated?

Mx are known for the diff on the back end. Also 135 are know for front diffs. The clutch pressures are different in the 135 to the 110 according to the manuals for the engineers at the dealers. I'd leave it alone. It's done enough at that power so it will still do it at that power. Want more then buy more.

Some of you clearly do not know these tractors very well:-
Clutch packs are the same in the 110 and 135.
The reason the 135 had diff problems is because case (like on the 5100 series and McCormick later inherited same problem) put the wrong ratio'D tyres on in the factory giving wind up, hence why they are "known for it". 135s with 20.8s - steer clear.
As for road work - there was a mod done done to earlier gearboxes that was updated to stop shaft wobble at high speed by adding an extra bearing (on the fwd shaft I think). Most had this mod done and this was a cause of failure on road work.
I've had experience. With a fleet of 110s all screwed anywhere between 150 and 190 (dyno proven) and you shouldn't have too much to worry about if you want some more poke. Just keep on top of servicing and you'll be fine.
20,000 hours of ploughing, power harrowing (6m), buckraking. hauling with 18T trailers and 3000gal tankers at 190hp with only a handful of issues cannot be wrong!!
Easily one of the most reliable tractors available - and when they do go wrong, they're relatively cheap to and easy to fix!
As for remap stud - you mean max fuel screw. Cannot remap a mechanical engine!
That's my two penny worth!

Your engine will go as far as you want it but I'm afraid the rest of your tractor will not if doing a lot of road work you will knack the diff and clutch packs great tractor when left as what they were intended to be but trouble when you start messing with them

If you do go ahead and give it some more - just make sure you change the Viscous fan for a solid drive: more power = more heat, so she will rise a little, but no problem once straight drive fan is fitted

If you wanted to do heavy draft work then yes.. tankering at 150/160 the stock viscous will be fine, so long as its not worn and will lock up.
