Hello All, so I have a 246c jay09047. I barely use any tool attachment on the machine. I bought a breaker hammer part # ZW750. I blew the hydraulic tube part number 4484588 the first time when I first used the breaker I replaced the tube and was using the breaker yesterday and I blew that tube again! I am not sure whats going on. Any help would be highly appreciated! These are the specs of the Breaker Wolverine ZW-750 Specs Weight: 1,160-1,230 lbs Impact Energy Class: 750 ft-lb Chisel Diameter: 3 in Hydraulic Flow: 12-20 GPM Operating Pressure: 3000 PSI Impact Rate: 450-1000 BPM Mounting: Universal Quick Attach Hoses: Dual hydraulic attachment hoses, does not require high flow Thanks
Wondering if it matters which way the hoses are hooked up? What hyd. pressure does your machine have? I think some of the newer skid steers are over 3000 PSI.
Hey Dave I think the 246c is rated to 3335 psi. I thought if the hydraulic hoses are hooked wrong you won't be able to run the breaker hammer? But I am not sure
I wouldn't think it would work hooked up backwards but not sure. The manual should tell you. You are 335 PSI over the max. PSI rating of the breaker. There may be a way to lower the pressure under 3000 PSI. You can also contact Wolverine. They say USA but I suspect their attachments are made in China. They look like what Ritchie Bros. puts in their auctions with different brand names but identical products.
Auxiliary line reliefs are set to 3553 psi for std flow and 4496 psi for the XPS model. If anything blows it should be the line relief. Have seen a few of these pipes split. Usually happens on a bend. Line reliefs are remove and bench-test only. I reckon you just have bad luck.
