my flu419 will not move in any gear

[speedbrakes]

driving on the road my flu419 just stopped pulling as if it was taken out of gear now it dont move at all where do i start?

HI Speedbrakes, I just bought my 419 and wanted to see if you ever figured out your problem? I have driven mine about 3 miles total and when I started from a stop sign, I went through first gear and when I shifted, it would not pull in any gear. I had to go to lo/lo and it started?

Neither of you are giving a lot of detail. Does the shifter feel like it is getting into detents? Does it stall when you let out on the clutch, or does the motor spin as if there is no load? Can you engage the PTO and use the backhoe(if so, the clutch is working). There have been cases where the high/low air splitter on the 1-4 shifter got stuck between high and low and the truck would not move. You need to give more detail about what is and is not working. “Will not pull” means different things to different people. And buy a set of cab tilt brackets. They are great repellent so you won’t have to tilt the cab.

A year and a half later, still pulling/pushing my 419 around the property to use the backhoe. Pushed clutch in one day with a load of dirt and hasn't moved on its own since. Thought it might be the air shift solenoid, but have to tilt cab for that. Recently read that someone replaced a blown fuse and it fixed their problem. I may inspect them this weekend

No reason to rush these things, right? Jeez, I thought I could procrastinate with the best of them, but you have me beat. Badly.
Besides, why tilt the cab to check the air shift stuff? (I'm also lazy, so I tend to do things the easiest way, as long as the result is still the right way).

I read (long time ago) that i had to tilt the cab to access the air shift soleniod, but pat356jones wrote that his mechanic was able to without tilting or cutting hole in floor. I may have to revisit this with this new inspiration

You study all the drawings pneumatics and hydraulics and electricals and make a decision

There are a few things where I've read "You must do this or that". For the most part, so far I've successfully just done it, without doing "this or that" first.
Not sure the air cylinder is one of them, since I've never worked on one, but it does sound doable.

“They said” is one of the most dangerous phrases on the internet.

Hi Speedwoble - I have been looking through posts trying to diagnose my (latest) problem, and I noticed the question you posed above: "Does it stall when you let out on the clutch?". That's exactly what mine does. I know I have an air pressure issue. Pressured up the system externally and air was leaking out the valves in the air brake booster. Bought a rebuild kit and rebuilt it. Thought I fixed it but now it leaks air out through where the top of the 'can' is held on by that wire that fits in the groove. I have not properly introduced myself to the group - mainly because I don't know how. I have an MB4/94 my father-in-law purchased and used on his farm (engine built in April, 1975). It's been sitting rotting for decades, and I hope to bring that one back from the dead. In addition, I purchased someone's failed rebuild along with a crated (rebuilt) engine. For unknown reasons, somebody painted it blue (WHAAA??). I have been working on this 8 ton puzzle for almost a year pretty steadily, and I have at least got the engine running - it purrs like a kitten, that is until I let out the clutch. It bogs down and dies. I cannot engage the PTO, so from your post, it seems clear I have a clutch issue. Big picture, what shall I try to fix first - lift the cab and try to adjust the clutch slave cylinder, OR should I try to solve the fact that I cannot get the system to hold air? I have no idea if the compressor is even working. I have had a lot of ups and downs with this thing, but considering I started with (literally) a bucket of bolts, with NOTHING labeled, LOTS of missing parts, other parts in buckets that I didn't know what they were, etc., I've been pleased to get it to this point. Trying to win a bet my wife made with my brother in law. I have to move the thing on it's own power, dig a hole, put the dirt back and drive it under it's own power back to where it started. I have till January to get it done. Other than it's very clear I should have my head examined, any thoughts? Thanks! -Sean

These are some puzzling issues! As far as F800's problem that seems a lot like when I was using my front end loader too much like a bulldozer as I tore down an old barn. Either I overstressed the system or it was just time, but the clutch slave cylinder blew its seal and I had no clutch. Even though I had read/heard you can replace the slave cylinder without tilting the cab I decided to get a set of the brackets and tilt the cab. It was a pain in the butt, but not too bad and it gives you a chance to look around and take care of other things that might need attention. My shop chain hoist really made the process doable by myself . Happy to say my SEE is back in operation. Now back to chasing hydraulic oil leaks!

Hi Frankenmog
I am curious does your MB/94 have the air assisted gear splitter like the SEEs? I thought that was unique to the SEE version. Maybe your air is only for your brakes? I hope you can figure it out and win the bet!

Hi BEL. My apologies. I wasn’t clear about which machine I was referring to. Yes, I have an MB4/94, but other than the mention that I had an MB4/94, all the post was about my FLU-419 SEE that some brainiac painted blue. So, in my post, everything after “In addition, I purchased someone's failed rebuild along with a crated (rebuilt) engine. For unknown reasons, somebody painted it blue (WHAAA??)”…was all about the blue SEE. That machine, that I’ve pieced together from bits and bolts in buckets, a replacement engine, lots of parts purchased through our friends at EI, etc. is the REASON for my FrankenMOG moniker.

Ok Frankenmog, Thanks, I was confused about which problem child you were referring to! Good luck. That SEE is blue for sure! Hard to imagine the thought process behind that paint job! Wish I could be more helpful with your issues.
I had the backhoe off of mine as I had recently raised the cab. During that time I had a shop rebuild one of the down lock cylinders which had been leaking profusely. I put it back on and had the bright idea to test it while the backhoe was off. I engaged the pto and let out the clutch and was initially surprised when it bogged down and killed the engine. Of course I overlooked the big picture that the system requires a flow of the hydraulic oil. I guess that is just an example as to one reason a SEE would bog down and die when the clutch is released.

Hey BEL, my apologies for the lack of a response. I’ve been simply trying to figure this stuff out by myself (as I really have all along - as guided by the technical manuals, of course), so ’ve neglected responding to your forum post. OK, I don’t THINK the PTO is engaged, but that’s something to check for specifically. If memory serves, with the clutch disengaged (I.e., the clutch pedal depressed), the PTO shifter does not budge. My hope is, this failure to do ANYTHING but bog down and die when the clutch is released (engaged) will become resolved when I can FIRST figure out why I cannot get the system air pressure to build to anything higher than ZERO. I will look for clues regarding what I should do next - by searching previous posts.

Cheers
