Buying and fixing a boom lift : 92 JLG 60H 4x4

In this video, I buy another boom lift: a 1992 JLG 60H 4x4 with the ford LSG 423 gas engine. I fix a bunch of problems, so I can use it on my house.

Hey Jesse. Gotta love workin on the boom lift! When I start mine, if it catches but doesn't start I almost always have to cycle the key to try again, or hit the emergency stop in the basket, just like yours is doing. The hole on top of the elbow above your carburetor, mine has a wingnut and a bolt that goes down and holds that elbow in place. If the elbow is tight enough to stay put as it is, you can probably just plug it. Do me a favor and stick a gopro on a stick up inside that boom and take a look at the chain. You want to see a spot where it has been running over a sheave. Just make sure the chain is in decent shape. It's probably fine, but until somebody looks you just don't know. Thanks for the shout out. My video of putting that beast back together is coming out tomorrow. Man, what a job!

[@jmuller86]

ok, I will have a look at my chain. do you put the camera in from the back or the basket side? I saw some of your videos about inspecting, rebuilding that boom lift and man what a job that was. I would not tackle that unless I had every other thing on my checklist done first (which for me will be in about 3 years, assuming nothing else comes up) finishing my house, building a new garage, building a small cabin in the adirondacks, fixing up my jd450 track loader and a few skidsteers I bought last year is just a few things on that list, and it's growing. I am glad my boom cylinder wasn't leaking like yours. That was one massive cylinder. How would you even bring that to get it repaired if you dont have a decent sized trailer? that is why its good to be able to rebuild it yourself.

Yeah, I was going to mention Jon at FarmCraft 101 as a good guy to talk to about this machine. Due to the timing of the video releases I don't know if this is the one shown in Jesse's house build videos or if this is a 4 wheel drive one that he wanted. Jon has the 4WD version and all new seals in it (and fire repaired electrical wires. Man that sucked what happened there to him).

I had a bunch of JLG all sizes . They have free online service and parts books. Newer models after 2001 have JLG scanner ECM I bought . Best machines Was John Leslie Grove of Grove Cranes in Pennsylvania. Check harness in tray on boom they crack get cut. Also all cable plugs in upper box . Intense electrical tech on these. They start on propane easier when carb is full of bad fuel. Check switch that it's on LP or Gas in basket .Often it is in wrong position. I am a Veteran on these since 1987.

OMG the sound of that paper towel when you were cleaning the valve sent shivers through me… aaaargh!

[@iwouldrathernot4274]

Those little 4 cylinder Fords are one of the best engines ever built in history, in my opinion. They just chug and chug and chug. Simplest overhead cam design ever, non interference and no fancy tricks to squeeze a couple of mpgs out of it makes for a drop dead reliable engine. Ive had a bunch of 2.3 Rangers and my current is a 2000 with a 2.5 and 240k miles. I wouldnt hesitate to drive it across the country tomorrow if I had to.

[@jmuller86]

that's good to hear. I always think of gas engines as a disposable cheap engine, but I guesf if there are this good its worth rebuilding if necessary

[@iwouldrathernot4274]

@@jmuller86 Funny you say that because Im in the process of rebuilding a 2.5 to go into my truck. Im not familiar with the industrial use of these engines, admittedly, but I have found much more service information on them from industrial manuals than vehicle manuals. The achilles heel of these engines were the exhaust valve seats in the head. They tended to recess over time and cause very random intermittent rough running, and difficult to diagnose because of the hydraulic lifters. The lifters would pump with oil and hold the valve off of the seat and cause a loss of compression, however by the time you get to doing a compression test the lifter will have bled down and you will have full compression again. This was most noticeable in passenger vehicles due to varying rpm and loads and usually happens while coming to a stop at a red light, so it may not be as much of a concern in industrial uses with more consistent loads. My truck has this problem but I have been driving it for several years with this issue, they just dont stop. Head replacements on these engines are also extremely easy, and can be done in a few hours with proper access. Parts are cheap, you should be able to get just about anything you need for this at a parts store by saying you have a 92 Ranger with a 2.3. Very well engineered engine.

[@wwcr893]

The groove in the rim is to be used to remove and install the tire. Put one side of the tire in the groove and the other side of the tire then has room to come off the rim.

[@jlinkhart]

I was gonna say the wheel was upside down right before he gave up 👍

[@oiu7890]

Leave the tire and rim on the machine. Turn valve stem up push bottom of tire in so it will go into the rim drop grove. Lower machine so tire goes into the drop grove and has some weight on it. This gives you slack to at the top to pry the bead off the rim. Then work your way a round on both sides to the bottom raise machine and pull bottom out repeat for inner bead. Reverse steps to mount the new tire. Get real tire mounting lube soapy water does not work very well.

[@davidhancock6049]

Once you have some tension on the tire bars push the other side down into the groove-this gives you more clearance to work around-its still a bitch of a job though !! Love your videos-cheers from New Zealand

[@clintk5367]

You have those guys that just want to do it the hard way!!

[@deadslow201]

And also there are tire lubes that really work. Use lube for tire lip, outside and inside (that is important when you are installing second tire lip), rim lip outside, and rim groove. If you just pour some soap water somewhere it does not really help at all. And you end up using force, and destroying tire lip and rim lip, just like in this case.

[@robertleemurrerjr.8245]

I recall Andrew struggling to dismount tires...he eventually cut the bugger off...mounting was a pain too and he used a ton of Cosby Sauce. Appreciate the effort you put in to these videos for the work you put in to boot.

I would say you got yourself a real bargain there. The previous owners had no idea of maintenance and fitting the solenoid the wrong way and really, not looking aftetr it made it seem a lot worse than it really was. Well done.

Best $112 you've ever spent. 20 years ago we cut off tires on a skidsteer with a reciprocating saw. For 3 days my eyes hurt from the violent shaking my head was taking attempting to cut those steel impregnated tires. We took them in also. And I change ALL my tires myself. Even the tractor tires which they wanted $1 an inch on the rim.

[@davidporter2374]

A farmer friend used old airplane tires on his corn wagons, the local tire shops couldn't mount them , he had to take them to Kingston ariport to mount them. Enjoying your videos. $110 is reasonable. The tires must come off and go on the the outside bead closest to the indent for the bead . Your soleniod diagnisis was spot on "S" is to "start" (Crank) "I" is for"ignition" as you said. The only thing is there is some soleniods with 2 smaller terminals with the "S" to start and other small to ground (external grounded).

[@thesmallenginekid]

When cranking an engine with a low battery, the voltage decreases, causing the starter to suck more amps. This can sometimes heat up the solenoid enough to melt the contacts together. Ive had it happen a few times, was very confusing at first. Also, changing tractor tire is easy. My 150lb self can change a 13.6-38 rear tractor tire in under 20minutes. Helps to have decent tire irons.

[@jonka1]

And to know which side of the rim it comes off on.

[@911Dox]

Jesse, you need to go to a tire shop and look at the long spoons they use for stripping tires and installing them too. They make life easier when you need to change tires. You will be best served and need to buy two of them. Also get the stem core remover/installation tool.. You now have enough equipment to make these tools worth the investment. I used to be able to reskin all tires in under 2 hours. With a well trained partner, we were able to do it in under 45 minutes. If you have an old propane tank, weld a 2 inch wide pipe to the can. Create a wide and flattened end that is curved to fit between the tire and rim. Fill with air then pop open the valve to pop the tire in place. You won't spend much and it will serve you well every time you need to change one or many tires.

Give you an A for effort on the tires great video keep up the hard work

[@blastingweevil2968]

the reason you struggled with the tyres especially putting the back on you were trying to put them on from the back if you look back at your video you will see a Depression near the front side around the rim you use that to let the sidewall of the tyre sit in it which then gives you enough room to stretch the tyre over the lip of the rim. just so you know in the future. :) you take off from the back and put on from the front . i used to fit commercial tyres for a living for around 20+ years.

[@ianallen2]

You take off from the front and put back on from the front. The bead fits in the recess you mention.

[@tbirdracefan]

It always has helped me to study the profile of the rim before working on it. That deepest portion of the rim has to have the opposite side's bead in it before the bead will go over the rim.

[@arlodewald5378]

Sorry : It's something I learned at a very young age . The new farm that we moved on to at my age of four in 1960 , there were so many old rusty nails everywhere . We got very good at patching tubes . Tubeless tires were not a thing nor was radial tires .

I was stunned when you said you would do the tires yourself. Way too hard to do those big guys without the right gear... not the size, I guess, but the ply rating. As when you needed the big cylinders rebuilt, it just pays to have a specialist do the work sometimes. When you give yourself a reasonable $/hr and spend real money on your employee, it adds up quick. I thought it would be closer to $100 per wheel... you got a hell of a deal! Like you said, even that would have been a good value. Especially when you factor in how much you saved on the tires themselves.

I really enjoy your videos. You have so much knowledge on the stuff you work on. Not trying to be an arm chair tire guy but I think you were using some of irons backwards. The curved end goes up so it hooks the edge of the rim and gives you leverage to pushdown the side wall. However, the price of mounting them makes that a moot point. good stuff Jesse.

I know I'm way late on this but when I do heavy walled tires like those. If they are reusable I saw zal mid way of both sidewalls and the across the section (the tread part) then dislodge the beads and saw zal them. Also when mounting them the Groove in the rim is called a drop center lay the tire down start with the rim groove closest to the tire. Use actual tire soap lube it up then put wheel in the tire after u get the first bead on flip assembly over and mount second bead

[@MUDNROCKS]

Jessie, you can't get the tyre off or on the rim when the opposite side of the tyre on the side you are baring is not in the rim well, thats what the well is for, you had half the tyre mounted but could not flip the last side over because you can't brute force a large tyre, it has to be in the well, have a coffee and think about the shape of the rim and where the tyre has to fit on and lock into place and you'll kick yourself for not figuring out the placement and order to get it done, honest it's easy. Also try getting wheels on and off the vehicle with a square mouth shovel under the wheel, you can lever the tyre up about 3 inches, lever it in or out and the shovel slides on dirt easier than the rubber tyre will, good for trucks too and much better for your back ..... go on ask me how a 63 year old knows these things. Cheers Mate love yr video's.

[@donanything6816]

Another great adventure. Thanks for the video, Jesse. 👍

[@merlepatterson]

It might be a good idea of pulling that cap and putting a liberal amount of (lithium) grease on that roller slide mechanism for that pilot valve that was leaking. It also sounds like the engine is under immediate hydraulic load (hydraulic whine with controls idle) that you may want to look into? If it's under load with controls at idle that means the hydraulic relief valve is being used to dump whatever the hydraulic load is, continuously. If I'm not mistaken the engine should idle with zero hydraulic load on it if all the controls are idle so that the hydraulic fluid doesn't overheat. With electric over hydraulic controls, you might be able to isolate it by disconnecting one control circuit wire at a time to see if the whine goes away at idle.
