LUBING FEL

Take a zerk with you so you can match the size and you can probably find them at any auto parts store. No need to buy them from NH.

( What you normally want in a grease is a lubricant that will not absorb water & has a high temperature rating so it will not break down under stress. Attached is some info I found on the net. )

The lithium grease I use is red in color, rated for extreme pressure and temperature, and is moderately water tolerant. A greatly appreciated bonus is that lithium grease is way less nasty than black grease. I don't even mind getting it on my hands. Well, not too much...

Jim should one expect to find metric threads used on the New Holland zerk fittings?

I have to say that I'm not sure about the tractor because it's made in Japan, but I think the loader has all SAE measurements as indicated by looking at the parts breakdown in your Owner's Manual. All the hydraulic fittings are in inches. Anyhow, an auto parts store these days should have plenty of both foreign and domestic sized fittings.

Now let me be completely candid.... I'm not sure there is such a thing as metric or SAE sized fittings. If anyone else knows the answer, please speak up because I'm gonna plead ignorance. /forums/images/graemlins/shocked.gif /forums/images/graemlins/laugh.gif

I do know that the New Holland parts manual has a lot of different part numbers for "lubrication nipples" as they are called. Of course, the parts manual doesn't list the zerks for the loader. It doesn't have anything for the loader except the joystick and front remotes which are on the tractor. /forums/images/graemlins/confused.gif /forums/images/graemlins/crazy.gif

I bought two boxes of assorted grease zerks awhile back; one was labelled SAE and the other labelled metric, so I assume they were labelled properly. /forums/images/graemlins/wink.gif Of course, when I accidentally knocked both boxes off the shelf at the same time, I just gathered them all up in one box. /forums/images/graemlins/frown.gif

And this place claims to have both.

Metric VS SAE fittings refers to the type thread for attaching the fitting. The same grease gun will fit either.

There seem to be coarse-thread Metric zerks and fine-thread Metric.

I bought a sealed baggie of zerks labelled Metric. They will start but they won't screw in past 1/2 turn on my Made-in-Japan Yanmar.

I got out my magnifier glasses and caliper - sure enough, the thread diameter was the same as the existing fittings, but the plugged-up old fittings I took out of my tractor had coarse pitch threads while these new ones were fine thread.

Back to CarQuest to see if they have coarse-thread Metric.

The fittings on my Kubota Tractor are not a thread that I was able to find at an Auto Parts Store. /forums/images/graemlins/frown.gif

I had to buy them at my dealer. /forums/images/graemlins/blush.gif

They are 6 X .8 or .75 mm. /forums/images/graemlins/confused.gif

I'm not sure about the NH Zerks. /forums/images/graemlins/tongue.gif

Thanks Bird and others, I also found this link to a place that specializes in lubrication fittings by searching for "grease zerks" on Yahoo.

Fittings & Adapters

I appreciate you guys helping me out here. It just suddenly dawned on me that I have had Japanese vehicles for a long time and always found zerk fittings at autoparts stores, but had not paid enough attention to the sizes. I have several assortments of sizes and I've always been able to find one that would "fit" although now I'm not sure if they fit properly or I was "recalibrating" my threads. /forums/images/graemlins/blush.gif

Just yesterday, I replaced the zerk fitting on my TSC rotary cutter's PTO drive u-joint just in front of the gearbox. It was missing and I went to my assortment and found a perfect 90° match I could screw in with my fingers until it was snug. I looked at the box and it said SAE type fitting.

So when I said you would not have to go to New Holland to get replacements, I should have added that I had never done it and perhaps saying an auto parts store would definitely have replacements might have been a little "wishful thinking." /forums/images/graemlins/smile.gif

Ron, I didn't know there'd be any difference, since I never had to replace one on my Kubotas. And the last zerk I replaced on a riding mower naturally had a pressed in zerk that apparently fell out and got lost. All the assorted zerks I had were threaded, so I just ground the threads down a bit on one and drove it in using an appropriately sized socket, and that worked just fine.
