I just bought a 1987 Huss Model 14190 log splitter from a rental store.
The man told me the hydraulics are slow. Got it home and he is right, but it splits wood fine. It has a 10 HP B&S, 4.5" x 26" cylinder with a 2.5" ram, 3018 Prince valve, all I know about the pump is its a 2 stage. The splitter is rated at 19 ton with 15 sec. cycle time. I did not time the cycle at this point.
The thing I don't like is it doesn't have a inline filter and only 2.5 gal hyd resivor. Where should I start and how big a mistake did I make?
Try to see if there is info on pump about make and model#.....
I assume 15 sec cycle time counts for a combined extend retract....
Then the flow points at a around 12.1 gpm pump (at high stage), and force points at a PRV set at around 2400 psi...
Seems like the 10hp B&S will have easy days on that splitter....plenty of power for a 12gpm two-stage pump
I would time the extend and retract cycle separately....
Also get a meter to check engine rpm's at full speed....should be 3600rpm to meet Haldex-Barnes flow ratings for two-stage pumps
2.5 usg tank is small for a 12 gpm pump, especially when PRV by passes flow at max pressure. Run the splitter for a few hours and
check, by hands on how/if/where heat develop above 120-140F range...and then we design new tank size from there...Also
use a 0-3000 psi pressure gauge to monitor pump pressure during operation , to see if pump switches between high and low stages....Make a "log", and write down all pressures during different parts of cycling with and without work load
Don't mount any filter till you know for sure you need a larger tank...
If splitter have been a rental for many years and still splits ok, there no reason to panic....even though I'd recommend to add a return filter
If splitter is slow (slower than promised rating), it can be caused by
>> a worned pump...this will quickly heat up the pump housing when pushing high pressure at low stage
>> low engine rpm's...
>>The stage pressure valve in the valve is stuck, and by passes high stage flow back to tank (suction side)
>> leaking piston seal....this will quickly heat up the cylinder when pushing high pressure at low stage
>> CV spool is interfered to make full movement (should be about 3/8"-1/2")...this will quickly heat up the CV
