Chipper Grease fitting on top/rear bearing of MacKissic TPH-122

[RalphVa]

Neighbor informed us that one of our tree limbs fell onto his precious property. So, I removed the bush hog and mounted the Mac TPH-122 to shred/chip up the limbs.

In greasing it, I found the top/rear bearing on it was missing the grease fitting; it seems to have vibrated out; threads are there; did not break off. The fitting is a very small one, smaller that the ones I had stored up. Could not get Virginia Tractor on the phone to check with them. Sent them a "contact us" note on their web site, asking about it.

Anyone have a Mac and had to replace one of these fittings? Lowes seems to have the straight (what I want) and 90 degree ones in 1/4" threads and "M8" threads. Told the wife to go in with the straight one I have and ask for one smaller. Didn't have another reason to go today.

Think 1/4" is what I need. Mac stuff doesn't seem to be metric. Think the straight one I have is maybe 3/8" or 5/16", a tad too big.

You're prolly right. You could try a bolt to see if you are. Ensure that it is clean as it doesn't do you any good to be pushing debris into the bearing.

I pushed grease into the hole, to fill it. The fitting had obviously vibrated out not long before I took it off last time.

Call MacKissic direct for parts. Their customer service has always be great for me...but i haven't needed them in quite awhile.

Cheers Ralph,

Thanks, oldballs.

I sent them an email. Strange their contact info shows in web search but isn't easily found on the site when you go to it. I copied the contact info and saved it.

Called the local JD dealership that deals with MacKissic. They didn't sound too encouraging.

Very tiny grease zerk.

I think all of MacKissic stuff is "Made In USA"....thus not metric.....if that helps. Probably any auto store would have what you are looking for.

Forgive me Ralph.....I was experimenting on posting a pic....and got the wrong pic.

Wife seems to have gotten one at Lowes this morning. She goes into all the stores with a mask on. I usually drive, but she left early today. Looks like it'll work. Smallest they make them; I guess. Wrench flats aren't much bigger diameter than the zerk.

No biggie, just proves your human(lol). The man that says he has never made a mistake, has either never done anything or.....

standard american thread size for zerks is 1/4-28 UNF & yes hex is same size as the grease zerk.

 

[RalphVa]

That's what it is labeled. Fit fine. Threads a tad longer than the one still in the lower axle bearing.

I put a dab of Goop on both of them to keep them from vibrating out.
