1450 Hydraulic Lift hoses

Roy Najecki · #1 05-24-2015, 12:45 PM

Two questions: The hydraulic hose between the Control Valve Assy and Hydraulic Lift Cylinder has a pinhole leak. When I compare the parts schematic to my actual hose routing it appears to be reversed. My hose from the lower port (B) of the Control Valve (nearest to the metal IN - OUT pipes) goes to the rear of the Cylinder, not to the front near the piston rod as shown on the schematic. And my hoses don't have the elbow (part #19) as shown on the schematic. The absence of the elbow doesn't seem to be a big deal, but having the hoses reversed is that a problem?

The part number needed is IH-548044-R2, which is stamped on the brass hose fitting. BTW - the brass hose fitting on the upper hose (port A) is stamped IH-548045-R2. I haven't seen any IH-548044-R2 hoses on our sponsors sites, or on eBay, and they are NLA from Cub Cadet. Is this something that a local hydraulic hose shop could make or should I wait until I find a OEM hose even though it will be decades old?

When you pull back on the lever it should lift, when you push forward it should go down. If it doesn't work that way, the hoses are reversed. If it does, they are correct.

Get a hydraulic shop to make the hoses. I'd get the missing fittings too, but that's me. They work as they are, I just like a cleaner look.

I got a pair of hoses off a power steering cylinder for a 316 Deere for $20 total from evil pay.
They are about 19" long and worked sweet on my 1650.
( No they are not Green)

Here is what deere hoses look like (not suggesting you buy these as they look cracked)

It's going to be a little more difficult without the original hoses to go by, but I would get the correct elbows and have some new hoses made up.

The thought process for getting the correct elbows is to eliminate some of the stress on the hoses where the ends are crimped on.

I can't remember if the mower deck went up or down when the handle was pushed forward.

NAPA is a few miles away and perhaps they will be open today and can make a new hose. I'll bring them my leaking hose for reference. Maybe even have the 90 degree elbow and new O-ring.

Thanks for the eBay listing but those hoses looked in worse shape than mine. Buying them might make sense if the elbows were detachable like on the Cub Cadets, but they are not.

BTW - about two weeks ago I noticed a dark stain in the grass where the 1450 was parked. I wondered I spilled gas or oil there and didn't give it much more thought. A week ago I changed the hydro filter and fluid and everything looked okay. Then yesterday I noticed another stain in the grass where the 1450 was parked overnight. Hmmm, that seems odd. Do I have an oil leak? An hour later I'm using the 1450 to jump the battery in a 149 that I haven't run in a few years. While doing that hydro fluid starts flowing heavily over the tunnel cover and pooling in the mower deck center pulley. After shutting the 1450 off, I thought that the hydro filter had spun loose. The filter was fine and dry so I tracked the wet area back to hoses at the control valve area. I wiped all the hoses so they were dry and clean and that is when I noticed a slight weeping at one spot on the hose. I can't see a hole but when the tractor is running that spot must be gushing under the pressure.

That is why I suggested you not buy those hoses, but as a reference as to what they looked like.
A good farm store/parts should be able to make up the hoses with a 90* fitting on then. don't know where you are located but TSC makes custom hoses but don't know prices or fittings available.
They make SAE 90* fittings if you need them, in the event your hose maker don't have them for the hose ends.
Seems your top fitting on the spool should have one and the hoses they make for you might be a bit less flexible, so keep that in mind,as far as location/length.

NAPA made up a hose for me today for $28. I'm in western Rhode Island, which is the rural part of RI, and do have a Tractor Supply nearby across the state line in Connecticut (a mile away from NAPA) but they don't make hoses. Anyway, I put on the new hose and all appears okay. Oddly, even though the hoses seem to be reversed when I push the handle down, the mower deck lowers. Pull the handle back, the mower deck rises.
