Tractor Maintenance: Changing Fuel Filter In A Mahindra Tractor

If you're looking to change the fuel filter on your Mahindra tractor, you've come to the right place. This is a step-by-step guide on how to do it, with some helpful tips along the way. It's important to note that there are two fuel filters in Mahindra tractors: a pre-filter and a main/final filter. The process involves removing the left side engine access panel, dealing with the fuel in the tank, and changing the filters. You'll also need to keep an eye out for the water sensor and be prepared to bleed air out of the new filter.

The pre-filter is a paper insert type with a removable bowl

There is a 10mm filter drain plug at the bottom of the filter, so you can slowly drain the fuel into a fuel can. Alternatively, you can remove and plug the fuel input line from the tank to the filter. The input hose is held to the filter banjo fitting with a simple hose clamp. Once you have drained the fuel, remove the filter bowl, swap out the paper filter element, and reassemble the filter. You should get a new O-ring filter gasket with the new filter, so change it if the old one needs replacing.

The main filter is different from the pre-filter

The Mahindra tractor has two fuel filters: a pre-filter and a main filter. These filters are different and are located in different places. The pre-filter is a paper insert type with a removable bowl. To remove it, you need to loosen the 13mm (1/2") drive bolt in the centre of the top of the filter. This will also cause the fuel in the tank to drain, so be prepared to catch it in a pan.

The main filter, on the other hand, is a spin-on filter. It is located behind the left-side splash guard and is more difficult to access. You will need to remove the left-side engine access panel and the splash guard to get to it. The main filter also has a water sensor attached to it, which should be left in place until the new filter is ready to be put on. To remove the old filter, use a plumbing-type strap wrench to loosen it, then spin it off. Be careful not to lose the O-ring seal.

Loosen the 13mm drive bolt in the centre of the pre-filter to remove it

To remove the pre-filter, start by lifting the hood of your Mahindra tractor and removing the left-side engine access panel. You will notice that the pre-filter is not a spin-on filter, so do not attempt to spin it off, as this could cause damage.

In the centre of the top of the filter, you will find a 13mm drive bolt. To remove the pre-filter, loosen this bolt. As access is tight, a socket won't fit, and using an open-ended or box wrench will be time-consuming. Instead, use a gear or ratchet wrench.

Caution: Loosening this filter will drain the fuel from the tank, so be prepared to catch the fuel in a drain pan or plug the fuel input line from the tank to the filter. There is also a 10mm filter drain plug at the bottom of the filter, which can be used to slowly drain the fuel into a fuel can.

Be cautious as you will drain fuel from the tank when you loosen the pre-filter

Be cautious when loosening the pre-filter as you will drain fuel from the tank. The amount of fuel drained will depend on how much fuel is in your tank. You can prepare for this by placing a drain pan underneath to catch the fuel.

There is a 10mm filter drain plug at the bottom of the filter can, which you can use to slowly drain the fuel into a fuel can. Alternatively, you can remove and plug the fuel input line from the tank to the filter. The input hose is attached to the filter banjo fitting on the filter with a simple hose clamp. If you choose to clamp the hose, be aware that some people advise against this method. Another option is to remove and plug the fuel input line from the tank to the filter.

Remember to have a drain pan ready to catch the fuel and avoid spills. Once you have drained the fuel or plugged the input line, you can proceed to loosen and remove the pre-filter.

The main filter is a spin-on filter

The Mahindra tractor has two fuel filters: a pre-filter and a main filter. The main filter is a spin-on filter. To change the main filter, you will first need to remove the left-side engine access panel and the left-side splash guard. This will give you enough room to work.

Next, you will need to remove the wiring looms that are blocking access to the filter. Remove the reusable zip ties to move them out of the way. Then, remove the electrical plug on the water sensor that is on the bottom of the filter. Push the release latch and pull the connector down to disconnect it from the sensor.

Leave the water sensor screwed to the bottom of the filter to avoid pouring fuel all over the starter and solenoid. Use a plumbing-type strap wrench to loosen the filter. Work the old filter out of the confined space and dump the fuel into your drain pan. Now, you can unscrew the water sensor from the bottom of the filter, being careful not to lose the O-ring seal.

Work the new filter into place and spin it on. Be sure to lube the gasket with some clean fuel first and snug it down. Screw the water sensor to the bottom of the filter and reconnect the electrical connector. Now, you need to bleed the air out of the new filter and prime the filter with fuel. To do this, open the bleed screw—it's a 10mm drive located on the top and to the rear of the filter adapter. Use a 10mm gear wrench to loosen it. Do not remove the bleed screw; just back it out enough so air can escape.

To prevent pouring fuel all over the starter, stuff some paper towels or rags into the space behind the filter. Push the primer cap down several times until fuel instead of air comes out of the bleeder and the primer stiffens up. Now, snug down the bleed screw. Check for leaks and try starting the tractor. The engine may start and run for a bit and then stop due to trapped air. If this happens, try priming it again. If you trip the Check Engine light, don't worry—just keep trying until the tractor starts and runs smoothly.
