Cat 977L Fuel Leak

[jezow2010]

In an effort to close this out for some other poor soul that has the same issue as we did… we found the issue. The bleeder was not seating properly and apparently that tube is where is bleeds out.

It looks like someone whacked it and bent the threads so when it was ‘tight’ the valve was not seating properly. Got it tightened down and the leak was gone!

Unfortunately, the fuel leak did not solve the knock. Looking for a good 3306 if anyone has any leads!!

with the motor running loosen the fuel lines one at a time and see if the knock goes away.
If it do change the nozzle on that one .
If that cures it change them all.

When I shut it off it stopped very abruptly. I went to turn the fan over and it would not budge as it would before.

What is the interchangeability on these 3306 engines? I see different injection systems like we have on the two machines and then I see direct injection engines. Can I put a DI 3306 in place of a PC one?
