replacing a broken grease zerk

[Marveltone]

I've found that NAPA carries the "square" type E-Z outs. That's what I used to pull my broken zerks out. The fact that zerks typically spend their entire lives embedded in a coating of grease really does aid in the removal process, as there should not be any rust to contend with.

Well, I checked in at the hardware store. They had a five packk of Master Mechanic ez out extractors for $12 bucks. I went home and drove the main pin that secures the outrigger to the tractor just over 1/2 of the way out to expose and free up the zerk hole. I thought I may have to drill out the bottom out of he remaining zerk threaded body. With the fivee pack of ex out extractors I picked out the largest one so it was not necessary to drill w/o drilling away the bottom panel of the zerk body. It was out in no time.

I have replaced zerks before on this backhoe and the book swears they are 1/8 th pipe thread. The thing is I have yet to replace one that it fails to feel like the thread matches. I have and tried them also in metric and they dont make a fit either. It's in there and takes grease.


thanks for all the suggestions.

I'm with 2458n. I've always had better luck with the "square" ez outs as opposed to the spiraled type. ~Scotty

Me too.

I've found that an old allen wrench works pretty well in a pinch.:thumbsup:

Rimshot i have just replaced some on my Kioti backhoe and mines were 8mm zerk !!!!! I'm surprised that yours are of a standard thread....

I think that 8mm is the same as 5/16 "

Well now! I have a Kioti KB2465 backhoe and on pages 13-36 through 13-37 of the backhoe owner's manual it shows a cylinder and parts ID page. It shows and identifies this object as a grease nipple, p.t (pipe thread) 1/8th inch, part number GNIT-0181. Strange that they would use both metric and Pipe thread.

Keep in mind that 1/8" is the nominal inside diameter of the pipe, not the OD of the pipe. OD is probably closer to 3/8". A 1/8" NPT zerk will have the same OD as the pipe.
