Great content, need more mechanical videos

[@theTurnandburn5]

I wish I would have made more when I was in the shop. I'm trying to get a welding job atm. Might be getting some of those videos.

[@grayguy19]

Thanks for that bud. Just what I was looking for. If you got anymore for the JLG machines. Love to see em

[@theTurnandburn5]

Ya, unfortunately I didn't have time to make video but ill do some post breakdowns on boom work and diagnostic as soon as things slow down.

[@grayguy19]

@@theTurnandburn5 the telehandlers are new to me. Anything helps at this point!

[@theTurnandburn5]

Not really sure what you wrote there, but I haven't worked on that machine, still it looks like a skytrack, so it should be similar to the rest of the industry, the brakes should always be on, unless the machine is running and you turn the parking brake off, if that's not the case then you either have massive damage, cut lines, or you're manual release bolts on the axle have been turned in.

[@nicholasbratzler]

Yeah just looked today the axle is a Dana/spicer 212 I have something fishy going on as the master cylinder for that axle is dry and won't bleed. the park break doesn't work makes me think the manual release is engaged. Hopefully due to a leaky brake piston instead of broken beville washers. Sad as the machine has under 3000 hrs on it previous owners didn't know what PM is I guess

I am having trouble removing the rear axle shafts. One service manual i read said to put 7 bar into the rear brake line to allow for rear axle removal

[@theTurnandburn5]

I don't believe so. There's probably a set screw that you're missing. Check the housing for a small Allan key. Sending pressure usually engages the brakes, so removing the line should disengage them.

[@kyles234]

@theTurnandburn5 I removed the set screw for both axles. In the service manual there is 2 one on top and bottom. This axle only has one on top. I'm thinking the axle seal bushing is rusted into the axle housing.

[@theTurnandburn5]

@@kyles234 ya, then that is most likely. Maybe a bit of heat on the housing and smack it to break the bond, but im guessing you already know that if you got past the king pins. They are usually the hardest part. There shouldn't be anything else holding is, so give it the beans.

[@devanandmagram7783]

Please let me know how to pull the rear axels, mine is really stuck

[@juan20cp]

Good evening, i have an oil leak from Front Axle breather of Dana Spicer. 223/ 50-006. I check sight plug and its come out dark and looks overfull. Waht you recommend to get that fix? I believe its a break seals gone.

[@theTurnandburn5]

Sounds like brake Seals. The oil has to come from somewhere. You have to pull it all apart and change all the o rings.

[@alexmontoya473]

Great video! Really helps since there is no other content out there. I do have a question though, if you can help out in anyway would be awesome. I have a 2013- JLG G10-55A. Rear diff has a vent on the driver side that sometimes pushes fluid out, which I'm guessing are the brake seals failing. My question for you is the front diff or maybe both idk sound like the brakes are dragging or stuck, brake peddle is really stiff. What could that be?

[@theTurnandburn5]

It's possible that the bolts that retain the slave cylinder have broken or backed out. That's actually what happened to one of our units. But the brakes weren't stiff. If just felt like their wasn't any power because the brakes were dragging. Maybe your brakes are just worn. Not sure. But ya, if oil comes out of the breather then your seals are toast.

[@heliguy02]

Glad to find this video. It helps a lot. Quick question though. My JLG telehandler 6042 has good parking brakes, but the service brakes just barely work. Any idea why that might be? lt looks like they both use the same brake discs.

[@theTurnandburn5]

Your right. I would check the parking brake release bolts. You'll have 2 or 3 that push on the back of the slave cylinder.... I guess it's more of a diaphragm. If it's not that you can bleed your brake lines like a regular car, but even easier because the hydraulic fluid flows constantly unless the vehicle is on and parking brake off. Other than that is out of my area of understanding. The nice thing about JLG though, is all their service manuals are available on their website... I believe.

[@heliguy02]

@@theTurnandburn5 ok. I will check these things out. Thanks for the reply

[@nicholasbratzler]

So i have a rs8 gehl telehandler front axles have no brakes at all no parking brakes at all bought check the master cylinder no fluid any I put in is gone any wisdom. I'm no slouch at mechanics but I don't want to just tear into it
