I'm not saying do this - just another possibility. Some of the protective covering looks melted. If the conductors underneath are OK, then it's not a big job replacing the covering. Damaged conductors can be spliced; heat shrinked; or electrical tape wrapped. Then protective covering. Or, cut...

If you're talking about the hydraulic oil filler cap, a Kubota "Plug" 38240-21410, Messicks has the Kubota part. The O-ring is 04817-50300, ordered separately.

When going into the creek, the machine needs to be shut down before it gets water into the cylinders. Water being incompressible, the connecting rods will have to give. After pulling the machine out of the water, glow plugs or the like need to be pulled out so that by hand cranking the water...

The real diagnostic test to to measure and record high and low pressures; and, temperatures. However, if it cools for half an hour and them goes warm, the first place to look is air flow (cleanliness). Even if the condenser is clean, if it is not getting sufficient air flow it cannot do the...

is there a way to test the new electronic module? 1. Assuming the alternator is functioning properly. 2. Overvoltage may indicate a bad connection. For example, earth. Cable jump around the suspect conductor(s). 3. Perform voltage drop tests to search for bad connections. Current thru a bad...

The new charge light flashes more than a strobe system, but the alternator is now pushing 16.8 v into the battery. 16.8 volts will boil out the battery. It should be closer to 14 and something for charging. The charge light flashing says that something is still not shipshape. Connections and...

I would expect to begin the trace from the regulator connector. Its pins are shown on the device with respective designators. IG, N, F, E, L, B. On the alternator, there is, or should be, a large bolt for +12 VDC. Also on the alternator, a plastic-body connector with several pins. Normally, one...

When the tractor is running I am measuring 10.5v across the battery terminals. Not charging. With the posted pictures we get a better idea of what is there. On the back of the alternator, there is a connector. What markings are on the alternator identifying the pins on that connector...

Bit of a recap on what is needed: Alternator brand and model number. Regulator brand and model number. Original was a 2-wire AC dynamo. 2 green wires. Original regulator essentially an AC to DC converter. Took 2 green wires from dynamo with AC. 1 wire, black, to ground. 1 DC output, red. With...

Likely a Yazaki or Sumitomo connector. For clarification, did the wire break or pull out of the contact? If the contact and connector were not damaged, an option is to just replace the contact with a new one crimped and soldered to the old wire. When you figure out the connector style, you can...

There is a trick to getting the fuel tank off. You already have the hood (bonnet) off. Now remove or move aside the instrument panel bonnet. The big trick is to remove the tank with what is shown as figure L13001, Item 50, which supports the fuel tank. First disengage the electrical connectors...

NGK and Bosch are well-known with good history. As pointed out, go to a good supply chain so that you minimize the chance of knock-offs. I would expect to pay about $20 each. Be wary of "really good deals" as you look.

Struck out…. Simple search off Model L3800 - keep getting 0 results. Model of L3800 should bring up choice of L3800H. If it doesn't work for you try looking at Coleman Equipment website under L3800H or L3800HST model. Or ask here for a part number.

I assume the HST pedal is out of alignment. Looking from the top of the tractor floor, the switch on the right of the upright pedestal, you should be able to move the HST pedal by hand with the tractor off, and watch the mechanical levers depress the switch button both forward and reverse. You...

L3800HST seat switch has three positions. Make sure PTO is set in OFF position. PTO actually has 2 switches in it. Jumpering without reading the schematic will cause problems due to mixed circuits. HST switch is physically found in the center pedestal on the right inside next to right foot...

Spring traps baited with peanut butter; and rat zappers baited with peanut butter. This will be a forever thing. May try coyote urine on the tires. Another forever thing. You don't have to catch a coyote, you can buy a bottle of the urine.

Go to kubotabooks.com and click on the picture of a tractor. Under tractors find the file L3800 wsm.pdf. No cost. If that file is an operator's manual, ask back here. Starter should be under warranty from tech or parts supplier.

I wasn't aware that the Society of Automotive Engineers had a "set it on fire" test. I would get a second opinion.

Go to kubotabooks.com and click on the picture of a tractor. Under tractors find the file L3200 wsm.pdf. No cost. If that file is an operator's manual, ask back here. One thing that the workshop manual (WSM) will help is a common vocabulary. Not sure what valves and locks we are talking about...

Valve clearance, cylinder compression, clear air intake -- injectors tested or replaced.
