Another Honda problem child

It still turned real slow with the plug out.

I'll try to disengage the pump and see if I can figure out the valve stuff tomorrow.

Thanks

Are the legs on the trailer down?
That will put pressure on the pump

Cycle all the hydraulic valves several times to release pressure on them but be aware that something could suddenly move.

On my 6 hp honda I put a bypass with a ball valve to release the hydro pressure. Once it's warmed up I turn the ball valve an go to splitin wood. I had to do the bypass as I had an 8 hp tacomsa (can't spell) that wouldn't start if any thing was hooked to it on the splitter.

Wonder if you might have hydraulic valve that is not in neutral position causing a drag on the engine once the pump tries to rotate. If you can separate the pump mount enough for the lovejoy coupling to pull apart, you might find the engine will crank over. You can eliminate the hydraulic system or better isolate where to continue searching. I have had valve deadheading hydraulic fluid on my splitter before that acted like a starter or battery issue.

Went there today and wiggled all the hydraulic handles.

Tried to undo the Lovejoy set screws but I guess they need some Blue Creeper.

Tomorrow's another day.

Just about ready to move the sawmill which is right next to it and use my backhoe to unload the logs from the trailer so I can get them on the sawmill with the backhoe after I set it up again.....that or firewood :( Truck the loader is attached to won't start either but batteries will fix that.

Mostly, I think you need to use that stuff more, Sprucebunny!

sprucebunny · August 22, 2019, 06:24:22 AM

I would if I could get it all to run at once. This loader problem is completely unexpected as it ran last summer/fall.

For any set screws it is best to use the hex keys that are mounted in sockets rather than the individual hex keys or the ones in a cluster. You can apply more torque and tap on them to fully seat them. Application of heat with a small propane torch can help. Cover the rubber insert with a wet rag and don't go crazy.

Thank you ! Good ideas ! I have several ordinary allen wrenches with half twists on them....

sprucebunny · August 23, 2019, 04:28:16 PM

I give up. Got one set screw loose and the other is stripped. They are not easy to get to.

I'll move the sawmill and set it up again and put the logs on with chains on my backhoe.

I got the Honda to start by seperating it from the pump.

Do we have any hydraulic experts here ???

Isolate the pump from the valve spool and fire it up! Put the intake and output hoses in a bucket of oil.

More likely the valve spool is trying to make something happen while you're starting than a seized pump? As someone's said. Or a blocked filter in the spool maybe? But that'll tell you.

sprucebunny · September 08, 2019, 07:23:46 AM

Thanks, Josh ! That makes sense.

I had planned to change the filter and pump some of the oil out so I'll make extensions for the hoses and try that.

sprucebunny · September 08, 2019, 03:34:44 PM

I could turn the pump by hand with the pressure line in a bucket.

Removed some stuff.

And now it starts !

Another success ! I'll take all I can get. There is still a pile of both somewhat broken and seriously broken stuff to go thru....

JoshNZ · September 08, 2019, 04:04:56 PM

Nice one. Must just be a blockage somewhere or a stuck spool. If you take that cap off the spool at the other end opposite the lever there's a big spring under a retainer clip I think. Which can be a pain to remove/get back on but after that you can drag the whole shaft out and see if anything weird is going on.
