Log Splitter Pump question!

[SPYDERLK]

Jim, Any foam in the reservoir? With what Iv heard, you must have a leak on the suction side. If your filter is on suck side be sure its ample for intended flow at the low differential pressure available. Check filter joints, o-rings, seals, and hoses for leaking fittings, pinholes in hoses, etc. Takes less for air to get in than oil to get out!

Wouldnt worry too much about the thread for a few cycles. Michigander is building a splitter. Outing splitter issues is probably a plus.

Dont worry about stealing the thread. I have been learning from you guys. I welcome all the tips! These logsplitters can sometimes be hard to figure out.

OK, thanks. Last winter I removed the shutoff valve I had on the suction (1¼" wr hose) line, and again replaced the spin-on filter on the 1" return line. There's no foaming in the tank. Valves are open center Prince detent. I have a log lifter on this splitter, with a separate detent valve. Supply is through ram valve, return runs through ram valve, then lift valve, then single filter/return line.
Pressure line from pump to ram valve is ½" I think, is that too small? All oil goes through that line first...
pic attached, see if the notes came with it.
Thanks for any assistance.

For reference, I have a homemade splitter with B/S 7 hp engine and a Barnes 13 gpm 2-stage pump. It's about the right size for the engine, about all the pump that 7 hp can handle, I'd say. Spends most of its time in high speed. For some reason, it pushes the 4" cylinder mighty slow even with no wood on the table, about 18 sec. out and 15 sec. in. I've tried lots of things to speed up the operation, because it's borrrrring. I guess as I get older it'll seem about right. I have a 36" cylinder but set up stops so I can adjust the return length to the length wood on the table.

The speed issue is pure volume. Probably not totally solveable with one lunger power. I posted in another thread about my 3pt setup with a PTO pump. Its really fast but I've 26HP to drive it and the pump is 21GPM no second stage. Full cycle time in and out on a 4" cylinder is under 10secs. And it doesn't slow down any while splitting. I've been told that the pump volumes aren't as high in actuall application as the rating. So If you've got a 13GPM pump your probably actually only doing 10 or 11 at best.
