Bump up lift capacity of L3400/LA463 Loader

john_bud · Sep 19, 2008

2700-2800 would about be my max. If you want more grunt, get some 2" diameter cylinders.

I'd be more curious to learn what it will do to/for the drive systems on the HST's. Running it over rated pressure could cause more problems then its worth.

just my $0.2..

Would this modification also increase the TPH lift capacity?

No impact. Separate systems, only thing in common is the fluid. The pump for loader and 3pt is on the side of the engine. The 2 pumps for the HST are in the transmission case.

Thanks for the input! Mine will remain at 2750 and works just fine.

Yes, the relief valve for the loader is the same one for the 3pt hitch. Don't expect massive gains. Unless your relief was tired and you then go from 3-400 psi under spec to 200 over spec.

It is important that you use a gage to measure the pressure, don't just guess that it was low and add a wad of shims. That wouldn't be smart.

I now have a 5000 psi wet gauge in hand and just need to figure out the fittings to hook it up. I will post when I have more information. Brian

Brian,

Sounds like you are well on your way. I am interested in what you find out about the proper fittings needed to put your guage together... I need to do the same. Pictures, part numbers... anything that would help the rest of us put a guage together, would really be appreciated. I look forward to your end results also... I know my L3400 with LA463 loader is a bit weak on the lift capacity, and I'd love to improve it. Thanks for keeping everyone posted.

If you can just hook it up to the bucket hydraulics, all you will need is a quick-disconnect fitting like the one below. I think the quick disconnects used on the bucket hydraulics are 3/8" ISO Series B fittings.
