Hydraulic lines.

I have 4 metal lines going under battery box and seat of my 450 crawler loader. One has sprung a leak. I would like to know what type fittings are on these lines. They look all the same. Two have male on one end and swivel female on the other. The other two have male on both ends. Figure it would be hard to get steel replacements. Last hoses to backhoe I had replaced cost an arm and a leg at Parker Store. Trying to save money by going online.

I haven't pulled the line yet. The location would make me think corrosion has settled in. The area was wet. The plywood that someone had placed under the battery was pretty rotten. The four lines were located under the soggy plywood. My next task is to get the lines out and check them over. Replacing the leaking one with hose would be easier than me trying to braze a rust hole.

True, but keep in mind steel lines are also part of the "cooling design". Exposed to atmosphere they cool the hydraulic system a lot better then lines sheathed in rubber. Though in honesty, it is probably not a huge concern on a dozer.

Got the 4 lines off. Took one over to JD Dealer to get some info. NPT 3/4 " male end with a female swivel on the other end. Didn't have female end in stock. Quoted me $30.00 for new 30" hose. Heard of another place that can make up new steel lines. I plan to check them out on Monday.
Now knowing what the fittings are I checked back online. $45.00 per hose. No savings there.

I always buy my hydraulic supplies thru surplus center. Here is what you need:
30 in hose. http://www.surpluscenter.com/Hydraulics ... gth:30\%22

3/4" male to female swivel adapter. http://www.surpluscenter.com/Hydraulics ... -12-12.axd

It comes to 22.00 their shipping is reasonable and quick. Figure it out what you need with shipping. There should be some savings vs going with mother Deere.

Thank you for the information. Ordered the hoses. Came to about $76.00 for 3 hoses, 2 adapters, and shipping.
