I have a Kubota G1800 spewing oil from the front of the engine (16 HP Kubota D662 diesel engine). Hard to see where the leak is from as pulleys and flywheel is in the way. I have pulled the PTO pully and flywheel to be able to see. In the center of the picture is the front of the crankshaft...

This is really info in case others have the same problem. So LS XR 4046 with about 100 hours, ECM fuse kept blowing within a few minutes of starting. It was the ECM fuse in the fuse box near the steering wheel that kept blowing. Not the two ECM fuses up near the battery. Took a lot of hours to...

KubotA G1800 with about 900 hours. So I have, what appears to be a small oil leak, where the inlet manifold attaches to the cylinder head. Oozing out between where the inlet manifold attaches to the cylinder head. If could be a bad inlet manifold gasket, but I can't imagine oil being in that...

You might also check under the radiator screen under the steering wheel. There is a voltage regulator tucked away under there, right behind the dash. I had the dynamo (basically an alternator) go bad, which then seemed to cause the voltage regulator to fail. Obviously you need about 13-14V...

I'm getting ready to do my 50 hour service. Oil & Filter. Hydraulic filter. Pre-fuel filter, grease, clean radiator, etc. My question is about some of the items on the list, specifically: Check front axle oil level. Torque exhaust manifold bolts. Torque of wheel bolts and nuts. Clutch...

I second RayK checking the u-joints on the PTO shaft. I have been chasing a vibration problem on my G1800 with 900 hours for a while. I was chasing it on the engine, and couldn't make it get better. It was slowly degrading. I finally found the issue on the front u-joint on the HST PTO shaft...

Folks, it took more time to figure this out than to do the install. Getting comfortable that I was tapping into the hydraulics correctly took the most time. Attached is a write up with some pictures that may help others. Rich TITLE: Installing 3rd function remote on LS XR4046 I installed a...

Thanks for the help all. INstalled and working nicely. Just need to better constrain the hydraulic lines at the front of the loader. Planning on some kind of bracket to attach to loader.

In case others want a source. ON the back of the ingnition switch are 6 posts. 3 were used, and one of the other 3 provided 12V when the key was turned on. Used it to power the 3rd function, and is working fine. The YELLOW wire in the pic is the one that provided a 12V source. Fused the wire...

Re: How to remove Power Beyond Fitting on LS 4046 Ok, well glad I asked and I am all stop until I am sure I have the correct line. Here is a better pic of the entire loader control value. Line 4 is coming out the bottom and going back to the remote control valve (I think that drives the 2...

Installing the W.R.Long 3rd function remote. Anyone alreadyi found a convenient source of power for the joy stick? 10 amps desired. Thanks, Rich

For mudstopper. It is line 4 in this picture. The G822S03 to the left is the loader value. The G827S01 is the Remote Control Value. So I am pretty certain that it is the Power Beyond Port. Definitely don't want to be wrong......

I'm installing a 3rd function on a LS 4046. I have to remove the power beyond value, and then attach this to the grapple valve kit. Here is a picture of the fitting to be removed. It looks like it has a nut on both the top and the bottom of the off coming hydraulic hose. How do I remove the...

I am not finding anything with the search engine. What size chain and which type steel should I purchase for a 4046 (46 HP) tractor. Nothing planned, just occasionally lifting, maybe pulling a log or something out of the ditch, lifting something out of the truck. etc. And what length is most...

Happily took delivery of a XR4046 with loader yesterday. Plan on getting the 3rd function remote, grapple, bush hog, box blade for use on my 20 acres here and for deer plots off location (trailer) where we hunt. Looking forward to getting the property cleaned up around here. :thumbsup:

Great thread. I just replaced the bearings on my Dynamo for a Kubota G1800. The parts diagram said three bearings, but there were only two when I took it apart. Not sure? ? Prett easy and $7 per bearing from local Kubota dealer who had them in stock. Cleaned up bearing surfaces with emery...

Here is a pic of the G1800 front PTO parts to help get a reference. I called out the pto shaft and front axle support.

Post 3 of this fix. The biggest surprise was the way the grease flows to the bearings. In this picture you can see the grease hole in the front axle support. Grease goes into this hole and supplies the PTO shaft with grease. Push the grease though that hole and the grease fills the space...

Post 2 of 3 on this fix. My second concern was getting the correct length grease fitting because I thought if it was too long and up against the PTO shaft, that grease wouldn't go in. Since I had to special order the front axle support I also ordered the OEM Kubota grease fitting. Notice in...

Post 1 of 3 on this fix. There is a happy ending! I just got time to put it back together this morning. I learned several things that I will share that might help non-pros who fix their own stuff. First the issue was the front PTO bearings on my G1800 garden tractor had come apart. The...

The bearings came apart in the front PTO of my G1800, and I have it apart to replace them all. They were in pieces so I couldn't tell the direction of the oil seal on the bearing. Looking at this pic, bearing (part #30) has ball bearings on one side, and an rubber oil (?) seal on the other...

Help! I am doing the 800 hr service and ready to adjust the valves. The kubota manual does not show the location of the timing window and it doesn't seem to be back in the area of the flywheel. Could it be covered up with the front end loader frame? Anyone know where to look? Thanks, Rich

I recently bought a house and with the house came a L3710 (750 hours) and G1800 (350 hours) to mow the 7 acres of grass. The glow plug light on the dash of the L3710 was not coming on at all, even with the temperation down below 45 degrees. The tractor would start every time after 5 to 7...
