Hydraulic outlets on B2601 for log splitter

[jyoutz]

When I was heating with wood, I would cut all my wood, then take a Saturday and go rent a trailer mounted splitter. A half days work and I would return the splitter. No maintenance, fuss, or costs other than the rental and a gallon or two of gas.

Right, went to the hose shop today, and got everything bought and made. He had all the parts in stock for it to in theory work. Was NZ$400 in total, and the whole splitter cost me only a bit over $1K, but that's the cost of doing things properly I guess. I really don't want this to leak or split.

The 90 degree swivel fitting on the loader valve works well and there's plenty of clearance. We stacked a 3/4-16 UNF straight fitting with a swivel, but it didn't add too much height. I had to go find a copper compression washer to seal it, which is what the hose guy recommended - the fitting didn't have o-rings.

The fitting on the transmission did not work. This has only 45mm clearance under the seat, so no room to stack two pieces. He had a BSPP 3/8-19 90 degree fitting, but it's not a full swivel - it won't rotate the full 360 degrees. There is a casting on the top of the transmission that fouls it, so I can't screw it in. Back to the drawing board on that one - he can order in a banjo that will fit then an adaptor to fit the hose we made. He had some concern that the banjo was too low, and the hose fitting then wouldn't screw on (it's larger diameter than the banjo height). But if I route the hose just right there's a gap in the casting where I should be able to screw it all together. The transmission already had a copper compression washer I can reuse.

All in all, I think it's looking very successful, but waiting on the new banjo that he's ordered to be sure.

I'll provide some photos once done and working, in case someone else wants to make this modification.

Yikes!!! Sounds mighty expensive to me!!! I hope that included all hoses and quick couplers.

Not surprised by the clearance problems. What size hose did they use and what type of hose ends?

BSPP fittings require either a copper crush washer or a bonded elastomeric seal like these.

SAE ORB fittings always have integral orings. The port on the valve is machined with a recess to receive them.

ORB = ORING BOSS.

Sounds like they used something else with a face seal but you got it done.

He asked me if it had a groove for an O-ring, and I said I hadn't seen one. So he gave me a flat face fitting and recommended a crush washer. I couldn't see any evidence of an o-ring so decided better safe than sorry.

Yes, hoses, Pioneer fittings etc. Parts in NZ are just expensive - all the parts he used were around $40-50 each. Two pieces of hose, terminations each end of each hose, two new Pioneer fittings, two elbows plus one adaptor = 11 fittings. Plus some labour I guess. NZ is a very low volume market for everything, so everything has multiple layers of resellers and middlemen.

Its not a groove in the typical sense. Its a carefully engineered seat. Heres the details.

I checked the exchange rate. 400 NZD = $234 USD which is not out of line with what that would cost here.

My cost for enough bulk hose to make the hoses plus the hose ends, quick couplers, and port fittings would be about $100. Thats without any labor.

My local Parker store would want 3X that if not more!!!

It was more than I expected. Not sure what I expected though, there's quite a few parts involved. It's more the comparison of what's a handful of hoses and fittings v's an entire splitter delivered from China at slightly more than twice the price of just these few hoses. But that's the cost of individual parts v's a single unit.

If you're forced to reuse one of those copper washers, anneal it first. They work harden when first installed and can be a booger to make seal when reused. Just heat it up to red with a propane torch, then let it air cool. It'll be back to it's soft state.

Great advice, I never knew that.
