Log Splitter hydraulic ram fitting broke off.

[WranglerX]

'Most" log splitter control valves (I have worked with) have 1/2 inch NPT female thread on A & B ports and usually use a 1/2 NPT thread nipple to connect to cylinder.... One would have to get a nipple with 1/2 inch NPT thread on one end and other end 1/2 ORB if ORB female was used.... Don't know but may be hard to find... Other option would be a mix up of adapters to get match up...

Just helped a friend repair a log splitter where male fitting became cocked in the female bung of the hydraulic cylinder. Dropped a big piece of pine on the valve assembly (unprotected BTW) and it skewed the fitting about 30 degrees. The top two or three threads were smeared on one side of the female bung.

They were ORB straight walled threads, I was able to first run a thread chaser followed up with a ¾ tap. Cleaned up the threads enough that the replacement male fitting threaded and caught at least three sections of the undisturbed threads. Took torque and didn’t leak. Success.

My fall back was to weld on a new bung like the one below.

I’m not a hydraulics expert. Maybe someone can enlighten all of us to the pros and cons of NPT Vs OBR fittings. Would guess the o-ring design of the ORB and a lock nut permit them to be positioned freely.

Lots of different solutions to this problem. Good luck with yours.

Good to have a link to that website. The ORB you mention would be better in most situations. In my case the valve is attached directly to the hydraulic cylinder via NPT.

FEDEX is the poop of shipping, and every one seems to want use it, can not understand how they (their computer/tracking system) can promise a delivery date when they do not have the package in their system yet.....Always have better tracking and delivery with UPS even good old snail mail (USPS) is better... I recently had a promised delivery date that was same date I ordered the item and they did not have yet picked up package from shipper.... Have two packages somewhere in their system now and deliver date keeps changing and there is no record of its movement in online enquires for what they call as "tracking"........

BUT one thing you have to remember just because seller/shipper states item is shipped, does not mean its in motion with any carrier, it just means shipper has it on its loading dock ready for pickup by carrier...

If you went to a local hydraulic repair shop they'd almost certainly have those fittings in stock.
I would have them in my shop at least, and I'd sell you one for $5 and you'd have it right away.

Also I'd caution to take the cylinder apart before welding it on. Both to prevent overheating any of the seals, and to be able to wash any contaminants from welding or grinding out.
Yes, lots of people will say you can get away with welding it assembled. And often you can.
But I've had enough cylinders people tried that with come in to be fixed that I figure it worth mentioning.

Daily I receive overnight first out FedEx and near perfect on time.

I think it could be they concentrate on the more lucrative shipping?

Ground is another story... different team, trucks, etc...

That is a good point about going to a local hydraulics shop. We have a place that basically builds hoses immediately. They are expensive but they are as close to the original configuration as possible. They check everything from the angle the fittings are to the exact length. All of the pieces are super high quality components. My job pretty much eliminates getting anything except on a Saturday or Sunday. One of the reasons online purchasing has been helpful for me. Thanks.

I am trying to remove the end cap on this 5"cylinder. It has a collapsible internal ring with about a 1/2" gap to allow this to happen, problem is, it simply will not release from the cylinder and with no holes like a snap ring would have, it is nearly impossible to get a bite on it. Plenty of rust buster from PB Blaster and screwdriver, to sharp small chisel to get bite on it and it is frozen. Man, I am eating up my valuable weekends on this stupid thing! About ready to just replace the cylinder.
