Had a long day playing around with these 404's. Got the fire truck cab one running good. checked compression 110,105,110,110,105,107. was pretty happy with that. Think that the bowl level is a little high but since the truck are not sitting on a flat surface I will leave it for now. generator...

So Here our lovestory with Ridgecrest CA. My Mom was dementing and came living with us in State College. She was 94 in the time and was in a wheel chair and loved camping. So i bought a low floor bus and converted it into a RV. We named her Dory because the bus was blue as is the fish in the...

Thanks for all the comments.. Tennmogger,Bob, thanks...but the " brilliant " part was gleaning it of other people before I pulled the credit card out. I Read more about it now and other smart people figured out that some grease nipples and brake bleeding screws are M7x1... So a lot easier...

Well, the kids were annoying so I thought better cool of in the shop....in the manuals about this zenith 32 carburetor I had seen a picture of the fuel level inside the carb.. The thread is an amazing uncommon M7x1 mm .. My cheap harbor freight set had the tap and die. In the pile of brass...

Tore the 58 unimog carburator apart. Fuel level was very high, so I think i just was so rich that it could not run at all? It did fire on ether and even had a little fire ball come out of the carb, may be liquid gas in the manifold? Either way, checked the fuel level and it seemed high to my...

Thanks Guyfang, Yes that ATF would have been better. was at Tractor Supply and they had 2.5 gallon 15w40 diesel motor oil on special for cheap. So that was my choice. Cleaned the gunk out of the oil filter housing and installed a new filter. Pre filled with a bit of 10w30 before install and...

Further experiments. no visible water came out of after I removed the oil drain plug . I had drained the oil out yesterday but left the cooling water in the expansion tank. Some thick honey brown sludge dripped out the oil drain, Decided to take the oil filter out as well and there was more...

Well success was a little premature... These units were sitting in the California desert for 10 to 15 years. Oil in this one seemed to be clean as in just changed, i guess 10 years ago. There was no coolant. Yesterday i just ran it for 30 seconds on idle and unfortunately did not check for...

Put the tank back on and filled with 5 gallon of gas. Hooked all up and connected the pump to a separate 12 volt battery.. Pump is pretty loud...So I learned that the front is the reserve tank and that the tank selector has to be in reserve... Next was the fuel strainer in front of the...

For documentation purposes only.. Tank after cleaning, pretty nice, no corrosion at all.. Zenith electric Fuel pump parts. Detail commutator and brush. Had to solder on the strainer to close a damage..there was a second impeller or so on the same shaft. It is sofar desintegrated that i left...

Took the tank out . Black liquid tar / varnish inside. Removed the pump. It was seized up. Tried to add some diesel and nuts and bolts but the tar was to thick and sticky. So with all covers of I took it to a carwash with hot soap pressure cleaner. Came out nice. Some pics if pump and carb...

Thank you, here is a picture. Inside the housing is an electric motor.. It seems there is a return line to the front tank as well. this is a 404 415 ??? 040-608 More studying to do. Johan

Hi Guy, hoping you would respond, I have the UKD 40 402 2132 Werkstatt- Handbuch 404S. I have read people writing about a factory fuel pump to avoid vapor lock. But found no details. The carb has two hard lines to the banjo bolt. I assume there is a pressure regulator inside the banjo bolt...

So I was in need of a truck that can get me thru some swampy area. Found one but the PO had two for sale . so well... Two it was. They came from California and sat in the desert for 15+years. Sofar I have removed the sparkplugs and dumped a couple of teaspoons mystery marvel oil in each...

Sorry to hear that, I did not get that far yet.

Thanks, will be interesting what you find. J

Evening folks... My FLU419 came with a stuck 4*4 /locker switch... Pulled the knob of and put some oil on top but it was to no avail. So I removed the switch and tapped the roll pin out.. There was a lot of gunk in the mechanism and I took the whole thing apart. You can see in the detail...

Cleaned it all of but no luck. The internal diameter is smaller at the side where the handle is clamped onto the tube. Took a 3/4" reamer and that fitted inside the tube upto the last 1".. After the cutting the 19MM shaft ran smooth in the 3/4" reamed hole. Put the whole thing back together and...

Thank you all...will do as suggested and see if it smooth.

Thank you... I disconnected the loader lever from the hydraulics to see what is sticking. The central shaft is more or less stuck inside the outer bushing making both levers more or less connected.. Took a while to get the central shaft out.. Fortunately the driver seat goes far enough to the...
