    The JLG 40F Boom Lift Dilemma

    Did everyone go home? I really need some info on that pulley, we're dead in the water without it. Thanks.

    The JLG 40F Boom Lift Dilemma

    I haven't posted in a while because we haven't had any problems we couldn't handle. But now our 40F has lost the pulley from the accessory drive below the distributor, that drives the alternator, and it's gone. Can anyone give me the dimensions so I can get another one? It's the Wisconsin VG4D...

    The JLG 40F Boom Lift Dilemma

    It's great to see that folks are still watching this thread! It's been my number one place for 40F info for almost 10 years. Thanks guy, especially off!

    The JLG 40F Boom Lift Dilemma

    Thanks Off, I guess it's the bigger one then, the tire shop said they didn't carry them. And of course I now have one leaking around the base!

    The JLG 40F Boom Lift Dilemma

    Does anyone know what the tire pressure should be on the 40f? The stickers that should have the pressure on them are gone and the manuals don't seem to say. Also what diameter are the valve stems? they're bigger than automotive so I'm guessing .625"? Other than tires, the old lady is still...

    The JLG 40F Boom Lift Dilemma

    Mine does this with the swing and I've got it caught in a corner before - frustrating! The next time it happens, try holding the control in the direction you want to go, and then just "bump" one of the other proportional controls. That usually makes mine work for the rest of the session. I'm...

    The JLG 40F Boom Lift Dilemma

    On the subject of the swing brake, is there a way to release it so that the boom can be turned by hand? We have an intermittent problem with the proportional valve for the swing motor and sometimes it refuses to swing to the right. It goes left no mater which way you push the control. Today one...

    The JLG 40F Boom Lift Dilemma

    I did some testing today. The boom goes all the way up in 45 seconds and comes down in 31, that's with the boom retracted and the engine at slow. It swings in a full circle in 1:20 sec. The speed forward is just under 1mph and with hi drive it's about 1.3. Reverse is about 1/2 mph slower. Of...

    The JLG 40F Boom Lift Dilemma

    Thanks Off, the controllers are Racine. I think I remember checking the output of the controller before but I'll check it again. What's confusing me now is that the hi drive just loads the engine down and doesn't make it go any faster. I'm guessing that the 2 may be related. Also, the other...

    The JLG 40F Boom Lift Dilemma

    Drive Speed I haven't posted here in a while because my 40F has been working pretty good for an old gal, but it's always been a little slow traveling. Now it's gotten to be painful to move it any distance at all, it moves maybe 1 mph max forward, and in reverse about half that. I'm kind of...

    JLG Boom lift 40' ???? INFO NEEDED and proper ID

    It looks pretty much like my 40F except the rear counterweight is different. Mine sticks out about 10" beyond the engine cowl and has a cutout on the right side for the battery.

    Thanks OFF, I won't be out there until next weekend but I'll give it a look then. Dave

    JLG40F engine question

    It's a side draft carb so I guess it's a VG4D. It is an old JLG40F so I'm not surprised that it's a little different. Dave

    JLG40F engine question

    Thanks again guys, a service manual would be just the ticket! :) By the way, I got to looking a little closer at that Hi Drive valve that has 2 coils, and it's the same dump and bang-bang that's on the bang-bang side except the BB only has one coil (just a bang I guess).:D Turning them both on...

    JLG40F engine question

    My JLG40F has a Wisconsin engine that has no ID tag. I believe that it's a VG4D or VH4D and it has a distributor, not a magneto. My question is, what's the timing supposed to be set to, and is it possible that someone has a scan of the engine manual? Thanks, Dave

    The JLG 40F Boom Lift Dilemma

    Hi Adam, I'm certainly no expert but I'll send you the parts and service manual that OFF sent to me. There are some folks on this forum that have experience with the 40F and I'm sure that they'll be glad to help. Dave
