Everyone,
I am missing a plug of some sort directly under the hour meter on the fuel filter of my D6 5R (pic attached). It was missing when I purchased the machine. A regular pipe thread plug (I tried several different ones) fits just a little too loose so it's not the correct part. Is this a special part? If so, does someone have one to sell? Thanks.



 

Hi, unstyled.
Does that hole look like it might have an o-ring to seal it, either in the hole itself or a machined face that looks like it could be there to receive an o-ring?

Just my 0.02.

Isn't that where the fuel line goes?

I agree. That is the relief valve and inlet bolted to the side of the fuel transfer pump.

Pretty sure that's where the fuel line running from the fuel tank goes.

Hi, Folks.
HMMMMMMMMMMM???????????? If that is where the fuel line goes into the system, that brings up another 'kwestyun': Where does the fuel line go to now - or does it go anywhere??????

Just my 0.02.

Could you run the fuel line up into the drain on the bottom and still have it work? Or maybe it's been converted to all electric...

Hi, PNWH.
O.K, so where did they put the batteries????????????? Is somebody trying to tell Cat something? LOL.

Just my 0.02.

Ha! I found the fuel line tucked under the side frame, pretty much out of sight to the untrained eye like mine! I would assume you guys are right, that's what the fitting looks to go to. I didn't have time to do much today, too many other things to do. It must be attached to the rear fuel tank as it feels like it. I've been working on the dozer since June when I got it with lots of hours cleaning, installing the fuel filter, injector pump, governor, freeing the drive clutch, speed control lever, other stuff with LOTS more to go. The pony motor is shot, missing parts, etc. That's going to be another "fun " job dealing with that - and expensive. Honestly, I've had a blast doing all the work myself (with the help of you guys). The main reason I joined ACMOC was for the experience all of you members have and are willing to share. I thank you all as always.

The fuel line connection is a 1" x 14 tpi straight thread (similar to 3/4 NPT but not tapered)
Takes a ferrule plus retaining nut to make the connection.
