How To Repair Oil Leak Bottom Of John Deere 145 Lawn Tractor

Recently on the net there accept been multiple folks with questions about removing their John Deere New Generation fuel tank to gear up a leak, or to access a steering motor oil line that is leaking. For tractors that didn't get a expert pressure level washing to clean out the clay that seems to accumulate around the bottom of the steel fuel tank, these tanks, or the steel fuel line that goes from the bottom of the fuel tank to the fuel pump tend to rust through from damp soil sitting in contact with these parts. How common is this issue a person may inquire? Attempt going to a salvage yard and find a proficient New Gen fuel tank some fourth dimension. With the New Generation fuel tanks at 50 plus years quondam, enough of time has passed for the soil acid and moisture to rust through these balmy steel components. Such is the case with my wife'due south 4010. She has owned the tractor for 20 years at present and it is always parked in the machine shed. But alas, last calendar week 1 day when I walked into the machine shed I could olfactory property gasoline, and a quick await around showed that the concrete floor was damp with gasoline between the front tires. A closer inspection showed the leak appeared to exist coming from the steel fuel line that connects to the shut off valve at the bottom of the fuel tank, and runs to the fuel pump. This fuel line runs nether the fuel tank support plate, and this support plate as well covers the hydraulic pump, and as well supports the hydraulic oil cooler.

For those who are familiar with the bottom side of a New Gen fuel tank, working upwards in there is pretty much impossible, so to make life easier the fuel tank needs to come out then the fuel line can be replaced. For experienced New Gen mechanics this will be a simple procedure, but there is ever someone who is attempting this task for the kickoff time, as indicated by the recent chatter on the internet. To proceed our hobby live and flourishing we need new collectors/enthusiasts to go interested in this wonderful atomic number 26 that the rest of us enjoy. By roofing some of these basic repairs we tin remove the mystery factor for many. By removing the mystery factor about some of these repairs, new comers may gain the conviction to buy that start tractor and join the rest of usa who have already institute the great fun that comes with this treasured atomic number 26. And then permit'south get started. We volition assume yous have already removed the rear engine side panels, and the radiator side screens. The cowl in forepart of the dash volition come off commencement followed by taking off the radiator cap, fuel tank cap, unbolting the rear hood bolts, turning the front hood latches out, and removing the hood. Life volition go a lot easier if you remove the muffler earlier trying to remove the hood. If your tractor is equipped with a pre-cleaner and bowl, you tin can remove this by gently borer on the bottom of the metal pre-cleaner housing where it slips over the intake stack, it is just a press fit over the air stack tube.

With the hood off, the front side panels will come off next to expose the fuel tank. At the tiptop of the forepart side console, in that location is a 3/8" carriage bolt that needs to be removed, followed by removing the nut from the 3/8" carriage bolt at the bottom of the side panel. There is no need to worry about the side panel falling off and getting damaged in one case these nuts and bolts are removed. At the front of this side panel are 3 leap clips still holding the side panel in place. Gently tap the side console forward to release it from these spring clips. The lower 3/8" carriage bolt sits in a groove with the threads facing up and it is a adept idea to remove these bolts and clean the rust off them, or replace them with new carriage bolts.

Under the fuel tank is a hand close off valve that the fuel line connects to. If your fuel tank is almost empty you can close this valve to save any fuel is still in the tank, or I adopt to use an electric external pump to pump the fuel tank dry. Y'all can remove the fuel line from the shut off valve at this time using a line wrench. It is best not to effort loosening this line with just an open end wrench because in most cases y'all will only succeed in rounding off the corners of the line plumbing fixtures, use a 6 indicate line wrench.

Before we get besides far into our project of removing this fuel tank we need to take a moment and mark the location of the fuel tank as it sits in the tractor. If nosotros don't mark how the fuel tank is sitting in the tractor before nosotros remove the tank, information technology's almost sure that the fuel tank filler neck volition not line up with the pigsty in the hood when we try to put the hood back on at the end of our project. An piece of cake style to marker the tank location is to utilise a straight edge off the front edge of the tractor frame rail and draw a line on the fuel tank every bit a reference when we put the tank back in.

On the correct side of the fuel tank you will find two fuel tank strap nuts. These nuts take a nasty habit of beingness rusted in place causing a person to twist off the strap stud. If you twist off the strap stud, you will take to buy a replacement fuel tank strap. To endeavour and go these strap basics off successfully liberally apply a good penetrating oil. If at that place are any exposed threads for the strap stud like we see in, run a thread chaser, or thread die over the stud threads to remove whatever rust or paint. Remove the tank strap nuts for both tank straps. Too remove the wire going to the fuel tank sending unit at this fourth dimension. If the sending unit of measurement has a separate ground wire like the white wire in, remove that likewise.

The top fuel tank strap has ii brackets, 1 on each side of the tractor where the radiator support rods adhere. The left side radiator support rod is easily removed past loosening the front nut, and then lifting the threaded part of the rod out of the bracket. While yous are working by the air cleaner removing the radiator support rod, prop the air cleaner up and so information technology doesn't fall when both tank straps are removed. By just loosening one of the nuts on the radiator support rod, when we re-install the support rods it will position the fuel tank correctly for the filler neck to line upward with the pigsty in the hood. Make a mental note to yourself that the top tank strap also has a hole at the front of the strap that must also line up with a locating tab at the front of the tractor.  Removing the right side radiator back up rod is a little more work than the left side. There are two brackets holding hydraulic lines in place, and the right side radiator support rod passes through these brackets. You lot accept to loosen these brackets enough for the radiator support rod to exist lifted gratuitous from the fuel tank strap bracket. With the radiator support rods gratuitous from the top fuel tank strap, the air cleaner tin can be asunder from the safe intake tube that goes over the peak of the radiator, and removed. If your fuel tank has a vent line fastened to the elevation of the fuel tank, remove the line and bend it upwards slightly. The fuel tank can now be lifted out the left side of the tractor. In one case the tank is out, inspect it closely where the bottom of the tank sits in the tractor, and where the tank straps clench around the tank for signs of rust pitting. At present is as well a good fourth dimension to supplant the hand shut off valve.

The reason we needed to remove the fuel tank to replace the fuel line between the fuel tank and the fuel pump, is because this fuel line passes under the fuel tank support plate. This is the only way I have found also quickly, and successfully thread this fuel line under the tank support plate. It works all-time if you pull the onetime line out towards the fuel pump, or towards the rear of the tractor. In that location will be plenty of dirt and gunk under the fuel tank support plate that a person should try to remove every bit much of information technology every bit possible. When threading the new fuel line under the support plate, again information technology volition work best to thread it in from the fuel pump toward the forepart of the tractor. Keep the end of the fuel line capped to prevent dirt from getting in the fuel line. Every bit we tin can see in the new fuel line is in place and we take attached cream to the tank back up to prevent vibration chafing on the lesser of the fuel tank.

Well, equally the I&T manual says, but reverse these steps and yous're done. Since we aren't the I&T manual we'll just briefly cover a few points to make sure the project goes smoothly. If you practice find a fuel tank that has some fairly deep pitting where it sits on the tank back up, or where the tank straps clamp around the tank in that location are basically iii options. Ane is to only put the tank back in the tractor if information technology wasn't leaking before, a 2d option is to find a practiced salvaged tank, and the third option is to put in an aftermarket poly tank that is bachelor from several suppliers.

Before setting the fuel tank back in the tractor, put the lower fuel tank strap in place. Information technology is quite difficult to get the lower strap in identify once the fuel tank is sitting in the tractor. If you lot replaced the shut off valve in the lesser of the tank, getting the new valve positioned correctly to connect the new fuel line can be a bit of a claiming. To aid make this as painless equally possible it will be helpful to get the fuel line continued to the shut off valve before the fuel tank is fastened in place. Without having the fuel tank attached to the tractor you lot tin move the tank slightly until the shut off valve and fuel line are positioned so you tin can get at to the lowest degree two complete threaded turns of the line nut by hand. The last matter you want at this point is to cross thread your new close valve or new fuel line. If you endeavour connecting the new fuel line with the tank attached to the tractor, it volition be very difficult to become the line fitting to thread correctly on the shut off valve.

With your fuel line fastened to the shut off valve, and to the fuel pump, you can line up the marks you made on the fuel tank with the front edge of the tractor frame rails. If you are installing a different fuel tank y'all volition want to leave the fuel tank straps loose until the hood is put back on and then you lot tin can line the tank filler neck upwards with the hole in the hood. The challenge here is with tractors that have an air intake pre-cleaner stack considering the fuel tank filler neck must line up with the pigsty in the hood as well as the pre-cleaner stack lining upward with that hole in the hood. In one case you have the filler neck and pre-cleaner stack correctly lined up with the holes in the hood, yous can tighten the fuel tank straps. Okay, nosotros just got ahead of ourselves.

Since we but ahead of ourselves let's back up a bit, with the fuel tank in place we can go alee and loosely position both tank straps. Simply thread the strap nuts onto the strap stud nearly two turns. This will go out the straps loose plenty to become the air cleaner bracket slid in place under the tank straps, and to put the radiator back up rods back in place. Having a helper concord the air cleaner in place, or propping the air clean up in position is helpful until the tank straps are tightened. Call up on the right side to reinstall the hydraulic line clamps once the radiator back up rod is positioned. Your tank vent line tin can now be reinstalled. The fuel approximate sending wire can be reattached along with the sending unit ground wire. At present would also be a good fourth dimension to reinstall the rubber air intake tube that goes over the elevation of the radiator.

If you are replacing the fuel approximate sending unit, the commodities pattern for the sender and fuel tank will only go together one way. The bolt pattern is not symmetrical.

Moving forrard, we tin can reattach the front end side panels by kickoff sliding the front edge of the side panel under the three retaining clips, then secure the carriage bolts and nuts. For tractors equipped with an oil bath air cleaner, no matter if you lot have a pre-cleaner stack or not, make sure the cone shaped deflector for the intake tube is 100% clean. It is quite common to find this area near blocked completely with a mixture of dirt and oil fumes.

With our fuel tank secured, radiator support rods secured, vent line in place, filler cervix and pre-cleaner stack lined upward with the hood holes, intake tube in place, and front side panels fastened nosotros are set up to put the hood dorsum on. With the hood on, look at the gap between the hood and the front side panels. To brand this gap await even, you may accept to loosen the two side panel retaining nuts and tilt the side panel forward or backward to get the gap even. Once the gap is even, tighten the retaining basics. After the radiator screens are reattached, the nuance cowl installed, and muffler back on nosotros are gear up to go accept some fun. Have the time to encourage someone new to start enjoying this wonderful part of our agronomical heritage.
