straight 450 loader hose length

Post by autigers100 » Wed Nov 13, 2019 8:55 am

I've recently purchased a straight 450 crawler loader which needs the bucket hoses replaced. The hoses have been replaced by a previous owner and are way too long and rub against the hood and the nose of the loader. These are the 3/4" hoses that run from the metal line near the rear boom cylinder pin to the metal line on the cylinder. The JD part numbers are AU40252 and AU40253. The JD website does not list the length of the hoses. Can anyone tell me the proper length for these two hoses?

this is for a 75 loader on a 450c, not sure they are the same. You could compare some parts numbers at

https://partscatalog.deere.com/jdrc/

The Deere web site for parts often lists the length of the hoses in the description under the part number

The 450c hoses are different. The JD parts website does not list the length for these hoses. Thanks Bruce

Unless someone with the same loader posts the lengths it looks like you will need to make you best guess on how much to change the lengths. As you found, the parts catalog on line gives the numbers and description (HYDRAULIC HOSE - FABRICATE), no other info. The only other thing I can think of is to ask your dealer if they have any information to fabricate these hoses by. They might have a reference of hose numbers giving the size, and length, of hose to use and the end fittings needed to fabricate a given hose. I logged in to check my ag dealer parts site and got the NLA, contact dealer message. The construction dealer's site didn't even find those numbers. Are all the support clamps shown in the parts catalog in place?

You may need to borrow Mom’s cloth measuring tape and make an approximate length measurement as Jim B has suggested. When you succeed, post the information back here for future reference, please. Best regards, Bruce

All of the support clamps are in place. I will contact the dealer and see if they have additional specs on the hoses.

I took Jim's advise and contacted the local JD dealer about the hose dimensions. They did not have a listing for them, but they contact John Deere and were able to get the specs. They are as follows:

AU40252 71.5 inches end to end
AU40253 75.5 inches end to end

Thanks again guys. David
