I have two Snoways giving me problems.They are both pretty old,maybe 7-8 years old.

#1 - plow works fine in the shop,and whenever I try it out.After a few hours,the driver complains it will not angle left,so he has to use a curb or something to move it.I repaired the plow side wiring harness last year,for a similar problem,as there was a broken wire to one of the coils (green wire if I remember right).I have gone over all the wiring,seems to be fine.I'm pretty sure it's a hydraulic problem though.

#2 - Doing the same as above,but not as bad,and very intermittant.It also started creeping down last storm,and will not stay in the raised position.The down pressure seems to leak down too,as when you put it on,the plow will go down,and the front of the truck lifts up.Then you cab feel it slowly leak down,to the point where the motor kicks in again to build up more pressure.It will just continue to cycle like that until you flip the switch,and turn the DP off.

All I have ever done to these plows is fluid changes every season,and a lot of welding.They have been pretty much trouble free.I have no mechanics guides,troubleshooting info,or hydraulic circuit diagrams.If anyone knows of any on the web,or you have a hard copy,please let me know.

Also,has anyone else run another oil in these plows besides the special Univis J37,or aircraft hydraulic oil ?

I don't know if this helps any, but I have an 8' 3" lobo that kept
creeping down. Over the last month it has been in and out of the dealers garage with just about everything replaced. Finally they took a block out of a new plow and replaced mine. Problem solved. Snoway reps in disbelief and not happy (under warranty still.)
As far as the hydro, dealer told me any light weight oil will do. I use rv oil for slideouts, only thing dealer sells and stands behind.

The DP was designed to bleed off. That allows the plow to rise if you go into an upwards slope. If it was hydraulically locked down and plowed into rising ground it could end up carrying the weight of the front of the truck.

As for the no swing, I'd bet you have a valve sticking internally. If there's a weak link in their hydraulic systems it is a tendency for valves to hang up. And their parts system requires that you buy the whole shebang, valve body and solenoid coil, for pretty steep dollars.

I know the DP has a relief valve,but it shouldn't bleed off.When the down pressure is engaged,the front off the truck should unload,and rise up.It will stay there until you turn it off.It used to work that way,and all my other Snoways are the same.

This one seems to bleed down pretty quick,and the front of the truck goes up,and down,and up and down.It seems to be worse as the plow now drops on it's own quicker.I think the plow creeping down,and the DP bleeding off are related.

If I could find some sort of hydraulic diagram,I could probably narrow it down a little more.

I remember a Snoway rep that used to be at the other site.Anyone know what happened to him ? or how to get a hold of him ?

I noticed too that one of the Snoways has torn the a-frame apart at the nose.Last year it was the quadrant\pump mount that got tore up on the same one.Does it ever end ....... :mad:

I sold my two snoways but we had a problem with one of them failing to stay raised during transport too. If I remember, I believe the dealer replaced the lift (ram?) which I think was "scored" and wouldn't hold its raised position anymore.

Anyhow the dealer I bought them both from was Cliff's Lawn & Garden in Oakville. He's been a Snoway dealer for years. You could call and ask Cliff I suppose. Another guy I deal with is Chris at Skyway Lawn Equipment in Hamilton. Very knowledgeable guy and has been around forever. He's a snoway dealer now, has dealt with Meyers, Western, and Curtis in the past.

We get our parts out of Cliff's in Oakville.I called them the other day looking for a few blowers,and talked to one of the service guys for some info.He said there isn't much available in service info and they just kind of "wing it" until they find the problem.

I will have to try the other place and see if they have any more info.I just want a manual before I open it up,otherwise I'm just going to tear it apart and figure it out myself.

Thanks for the tip.

Chris with problem #2 I think you'll find that the seal on the piston on the lift cylinder is bad.
Have replace two cylinders over the past two years on the few SnoWay's that have been in the shop for repairs, both had the same problem.
No one had kits in stock at the time other wise would have repaired them.
I think Alan is right with the valve sticking for the angling problem.


:rolleyes: John................

I had a feeling it may be the lift cyl,I don't want to know what that sucker is worth.

I'm going to see if I can tear into it tommorow and see.If it gets too expensive,it will get replaced.

Just when I thought I could help you out Chris, someone always steals my thunder! My snoway had the same symptoms that you are describing. I was going to suggest to contact John, due to the fact that he fixed mine for me! But he beat me to the punch.

I just looked up my repair bill, John replaced the lift cyl. and it fixed the problem. The cost for the cyl. was $200.00 bucks

I am alomost done repairing the broken a-frame,and have to finish putting the valve body back together.I did find the valve for the downpressure was stuck,so I am hoping that is some,if not all of the DP problems.I think the other intermittant stuff may just be a loose grill connector,so I'm going to rewire everything from the grille to the pump assy with new grill connectors.

Most of my problems with my snoway has been traced back to an intermitant ground, some of the wire ends were loose and corroded, a little r and r and its been doing fine. my intermediate frame has required welding, they must make this a weak link as its not built very strong, not sure if I want to beef it up and have other breaks as I can get to it for repairs.

Unfortunately, the SnowWay rep that visited the other site passed away a little over a year ago. His name was Bryan Holland.

I got a PM there from another rep that was "assigned" to monitor the site, but he never posted. Not sure if he was monitoring either.

Well,it's fixed,for the most part.

I welded in a new pivot for the end of the a-frame with bracing,and new 1/4 plate top and bottom.Had to repair the pump mounting plate too,as it got torn off when the a-frame let go.

If you have a Snoway,and it pivots side to side a lot more than you think it should,then remove the centre bolt,and check the quadrant and a-frame.The bushing like to tear out,as the plate they use to mount them becomes fatigued.

Part of the downpressure problem was a stuck valve.The valve was stuck in the up position,so when you turned the DP on,it went up.

I rewired the plow totally with a new grill connector too,and it functions as it should now.

The blade stil drops slowly,and the DP bleeds off,but that looks like a bad lift cyl.I'm going to leave it for now.

I will draw up some crude wiring diagrams in the future from what I figured out when reparing it.If anyone wants them,let me know.

Chris, check with Woodfield Canada, they are located in London. They used to be a Snoway dealer and he is very knowledgable about the ins and outs and problems those plows had. Reach them at 519-451-5763.

Welcome to the site,another local guy I see.

I have most of the stuff ironed out now,just the leaky lift cyl problem left.Thanks for the info though,I will give them a try next time I need some help.

Yes I remember that, I chatted with him often on IM.

Did you get it fixed Chris?

Yes,I did fix it.The DP valve was sticking,and a few minor connection problems.It worked the last storm.and seems to be fine except it still drops slowly as the lift cyl has an internal leak.
