HD36 Hydraulic help...

I've assembled the saw. The electric works, the engine and blade work.  The hydraulics, not so much.  With the engine on and the carriage all the way back I can hear the hydraulic pump running, primining all the new lines (I guess).  After 45 minutes, if I maipulate any of the levers I get no movement at all.  I can hear a change in pitch on the engine, the fluid level in the tank has dropped so I refilled it (ok over filled a little). but no movement from any of the rams.

 

How long does it take to prime? How do I trouble shoot?

I recently put some Hydraulics on my mill including the Gas hydraulic Power pack, Log loader and toe boards.. It only took a few seconds ok maybe 5-10 seconds for the hydraulics to start working.. Then an hour of cleanup in the shop when I noticed I fogot to tighten one of the connections. surprise

 

Sounds like you are running the electric pump..  Not sure i can help much with trouple shooting

yes it is the electric pump, and the contact plates are in contact with eachother

I've tested the pressure line from the pump and it sqirts under pressure, as does the reture to the resevior.

I took off one of the hoses that goes to the rear toe board and activated the valve, it is under pressure as well.

Reconnect the hose and no movement.  I can manuall tug on the ram and it operates.

Is it possible that the fittings are too tight going into the rams?

 

I'm stumped

I doubt the fittings are the issue.. I would be inclined to check out TSC for a Hydraulic Pressure gauge, install it on one of the line ends or T tap it in. and insure you have lots of pressure even though you have flow. althought you said eariler you could hear a change in pitch of the engine.

Are the other hydraulics working the same way. (log loaders)

Not knowing much about the electric pumps I wonder

Is it possible to wire the pump with the incorrect  polairity (pump running in reverse)

Does the Pump have a releif valve (anyting in the manual on how to adjust it.. (you may need the pressue gauge mentioned above)

My first all would be to Norwood.  very issue I have had with my mill has had an answer in moments with s call to them.

 

I would be surprised if they dont know where to look, and how to test the system..

Found it!  On the lower right of the manifold there is a micro-switch with 2 shovel connectors.  If you connect the magic red wire to the top paddle you get the problem I had.  If you connect to the lower paddle then everything works.  We made saw dust today, or as my grandkids call it "Man glitter".

I never got my electric pump to work properly. After a month of messing with this "fix" and that "fix" NW sent me the gas option. That showed up having been run and still had fuel and oil in it (although it was obviously brand new) at some point it was run, the fuel was not drained and that caused the carb to fowl. Another 10 days, two trips to the Honda dealer (30 mi ea way) and $80 later I now have working hydraulics. It seems the quality control at NW is laking! Oh and one of the power head cables snapped already luckily the head was in the down position,

It cut sgreat when everything is working properly smiley

Hello gentlemen!  I guess I may be the new kid on the blog, so hello to all!  I enjoy reading everyones stories and can only wish they have happy endings.  Anyways I have purchased (with my wife) a Norwood 36.  Big jump for us . seeing how we no very little about sawmilling.  My neighbour had another model, and made a good living with it.  They moved on so that inspired us to make this purchase.  So... I have had quite the time trying to assemble the 3 pallets of boxes etc but now am at the end!!! However I cannot seen to connect the hydraulic hoses together for the log loaders!  They could be quite handy if they were working if you know what I mean!  The couplers dont seem to open or mesh, so I even called norwood headquarters but they confirmed I had the right male and female connectors but sort of ... good luck with restling them together.  Sorry if this seems like a long letter but it would be cool to see these log loaders activate!  Any thoughts fellow Norwooders ?

The coupleings looked a little bulkey to me as well but when they line up the go on very easily.  Senfd me your email address and maybe a swaping of photos will help.

Thanks rdecker.

I had a neighbour pop in today and he showed me how the couplers mesh!  I couldn't believe   how simple it is. The DVD that Norwood has shows a fellow with ease coupling the lines.  Thanks for responding ,I was dumbfounded and even had Norwood sending out a new set of couplers. Thanks again!

Success! My issue with my hydraulics was that 2 levers did nothing. Rear toe board wouldn’t react and my log turner would only go up and down but wouldn’t rotate in either direction. All the other hydraulic levers were fine. It turned out that for some reason when the problem levers were moved, they just barely touched the bottom of the swivel bar to make an electrical contact! Made a slight adjustment and we are back to normal! Very happy about this issue being resolved. Hope this blog may help someone else as it sure stumped me.

Been out of touch for a while - glad you got it figured out. I’m all manual on my mill so I’m not a lot of help.
