Make sure the tool circuit is switched off. The front pump always runs when the engine does. When loader and tools are not in use, the output from the pump drains straight into the tank with the least possible friction and resulting heat. If either one of the spools behind the cab is out of...

Can't find the spec right now in the many pages of the manuals but I am going to replace my pressure lines hopefully this WE and will measure the actual pressure on my FLU419. (See edits I made on my first reply while you posted your answer).

1) The pistons for the lockers get full pressure via the fitting on the short axle tube. Additionally, the entire axle is pressurized at a reduced pressure against water ingress when 4WD is engaged via the fitting on the long tube. That pressure exists before the lockers can be engaged and if...

Thanks for the info. Did he recommend any specific viscosity for the Redline GL-4 oils?

I agree that in reality it will not matter what you pour into the gearbox for most SEE use cases and considering that the machines already sat for decades with the .gov fluids in them. However, since the price difference between the "right" lubricant and a "maybe right" one is insignificant...

The applicable manufacturer's specification for lubrication of the vintage Unimog gearboxes is MB 235.1 and several brands are listed there. Before we worry about the availability of the listed lubricants in the USA let's look on the German Unimog forums what oils have been recently used and...

I treated the tank with Biobor JF about a month ago. While this biocide will stop new growth, it cannot remove the detritus of the previous contamination. I will keep adding Biobor JF to any new fuel to hopefully keep this annoying crud from reappearing.

Getting tired having to clean the fuel strainer about 5 to 10 times a day, I finally drained the tank, pulled it out, and pressure washed the inside after soaking it with ZEP de-greaser. All the bacteria/fungus crap came off and only some slight surface rust remained. Taking out the fuel level...

I had the cap leak issues with a rebuilt cylinder on my skidloader. The backhoe bucket and left swing cylinders that are leaking on my SEE unfortunately need a complete teardown and also a new rod for the bucket cylinder. Still hunting for parts but will have to attack this repair soon.

If tightening does not work because the O-ring got nicked during assembly, it is still relatively simple to repair. You only have to take the pin out of the rod eye, slip the new O-ring over the eye, re-install the pin, unscrew the cap and stretch the O-ring over the cap into its grove. The...

First thing is to look for metal pieces or flakes in the oil sump. Anything you find there has been worn or broken off from the parts above. Check all gear teeth, clutch dogs, and shift forks for broken/chipped parts and pitting on the hardened surfaces. Check ball/roller bearings for...

Re: Bucket modification / Quick Tach conversion One of the annoying things of the original bucket is that it does not curl down past vertical, which makes it impossible to push yourself backwards with the bucket when stuck. Also, if you want to get the front tires of the ground you have to...

If you read the TMs you will see that both type of regulators were used and serve the same purpose. You may have to adjust the regulating pressure via the screw on top of the spring housing but that is easy. I bought one of the WABCO units just in case but my original regulator turned out to be...

Yes, the outrigger makes a handy tire de-mounting press. The hood in the background is a spare that was run over by GP personnel and now serves as an oil catch pan. At maximum extension the tire rubs slightly against the anti-sway bar in the front. I do not have the fenders mounted yet to see...

80 PSI is where this tire reaches its max load rating of 7160 lbs. I put the tire behind the backhoe base with the other side facing towards the woods and figured that any severe defects would show up at the max pressure. It took a whole lot less to seat the bead. I got some "Magnum Super...

Mounted the first two 14.5R20 tires on my SEE today. They are about 2.5" taller, noticeable wider, and a whole lot sturdier (much harder to mount) than the original12.5R20 tires. Both tires seated on the rim just with the SEE tire inflator; no ether needed. However, it took nearly half an...

Please PM about what you need moved.

Trailer may be spoken for; box truck still empty.

Were you able to tilt the cab just with the chain/strap in the front and the ratcheting pole?
