Can I snake those through with out major disassembly? It doesnt look like they'll fit through on the bottom side of the sheave. Just trying to get some confirmation before I attack this.
TIA

Have you downloaded service manual from jlg website?
Haven't done hoses on a jlg, but tie a rope to old hose and pull out, and use rope to pull new hose in. You may need to remove boom pads to give you clearance under the sheave.

I have downloaded the manual. I didnt find a procedure for just doing the hoses. It had boom disassembly steps. Pulling the wear pads out i would understand. I'm more worried about if the fittings will make it through here on the bottom of the sheave or if i have to pull the pin to get clearance.

So ues it can be done without pulling the boom apart. Take out the rear wear pads and prybar the mid section up to get clearance on the bottom of the sheave

Call JLG for instructions. They sent me 28 pages to disassemble my Skytrak10054 boom to install new hoses. Not found in the usual service manual.

10ks are a pain. 6s and 8s don't require the same labor. This is me and just how I do them now since I usually do them by myself and in the field. I either switch the Aux lines over if your machine has Aux plumbing and since I have a crimper if new houses are required I cut the fittings off and pull the hoses through and re crimp the hoses once I route them through. If you don't desire to pull the boom apart in sections thats the easy way. The fittings don't make it through the last section otherwise. I usually cut the old fittings off at the tilt cylinder and cut a notch about 1/2 from the end. Tie and a kite string through the notch then pull the hose out along with kite. Tie the kite off on the front of the machine then cut it loose from the hose and tie that off. Then attach a new kite and pull through the next section and repeat for each section. So I end up with a kite for each section of boom. On one of the hoses ill put two kites on it that way I got three kites just in case. Its not a hard job if you break it down in sections like that. Its not fun for sure but pulling one section at a time allows you to keep your hosed laid out and helps you from getting them run over each other. Its can be messy with grease and hydraulic for sure. I recommended marking your lines and taking them looses and putting a pan under there with the boom low and let gravity work for a while and get as much fluid out as possible. Thats been my approach that Ive stuck with over the years. There are however more than one way to do it and you might find a way that works better. Unless you got a hoist or a second machine and a helper pulling the boom apart is not fun. Not hard just requires more effort with putting wear pads back, chains and re setting the chain tension when your done
