Check out You Tube, might be a video on there to help you. I found one on my L3560.

It is good to be famiear with the bleeding procedure... you will need to use it if you run dry of fuel someday.

In general:

1. Bleeding is done in sequence from the filter, thru the injection-pump, finally, at the injectors.
2. 'prefill' the new filter to reduce amount of bleeding
3. There may be a bleeder ontop of the filter-housing to loosen
4. There may be a bleeder ontop of injection-pump which is loosened to help expell air.
5. Some engines have a hand primer pump. (many do not)

Crank the engine, (or using the built-in hand pump), snug each bleeder as fuel begins to come out.

On most engines, you need to loosen the pipe-fittings at all the injectors. Crank the engine. As fuel begins to squirt out of each one.... snug it back down.

Finally, try to start engine and expect rough running for a minute or so as the rest of the air is purged thru the injectors.


USE MARKER TO WRITE ON THE NEW FILTER (Engine-Hours and Date)

To change the fuel filter, clean off the area around the old filter, remove the old filter, lube the gasket on the new filter with clean fuel, and screw it onto the filter head. Whatever you do, do not never, ever prefill the filter before installation!! This is a 5-micron filter, you would be better off not changing the filter as dumping trash into the system. Below is a pdf of bleeding the system.

Just changed the fuel filter on our M62. Did the recommended bleed sequence. Tractor is starting but hesitates at start. Usually starts on the 1st crank, now it's taking two cranks. Ran it at 2000 RPM for a few minutes, but the hesitation at start is still present… any recommendations?

Thanks in advance for any help.

TRY THIS:
With engine idling, one at a time crack-open each fuel-connection at the head.
The intent here is to encourage any trapped air-bubbles to escape.

Consider gently wrapping with cloth before cracking each. (to catch escaping fuel)

ALSO:
Double-check EVERY connection which was opened-up to change the filters. Anyplace where air can get sucked into the system will cause problems.

Used the tractor for a few hours and the problem is gone - interesting that the bleed proceedure in the manual doesn't work completely.

Glad you were able to get the problem resolved.

Diesel engines are pretty simple compared to gasoline because there is NO IGNITION. All you need is compression and fuel... and it will run. (the "fuel" can be ANY type of oil..... When Rudolf Diesel invented his original engine, it was intended to run on OLIVE OIL)
