Loader Zerks for 100hp TYM/Mahindra Loader

4Papa · Jun 13, 2019

I have a 2015 T1003 TYM and I'm posting here as well as it's the identical machine to Mahindra's model of the same year. Anyway, does anyone happen to know the size of the zerks for the loader? Due to their recessed location in the loader arms, I snapped off a few nipples attempting to remove the grease gun nozzle while greasing this past weekend. I figured the stock fittings were a standard size but that doesn't appear the case. The stock zerks fit a 10mm socket but replacement 10mm fittings that I purchased both locally and via Amazon are too big for the socket. My selling dealer has no clue. This model loader also was used on the 90hp version. Thanks.

The could be any thread type. Buy an assortment. They could also be a press fit type- called “drive type”. Those look like the link below and the more expensive link above. Once you get the press in type out you can chase some threads and screw in a fitting if you want.

A 6mm zerk will probably have a 10mm hex for the socket and a 10mm zerk will have a 12/13mm hex. Just like a 1/2" bolt has a bigger 3/4" hex.

My dealer finally got some from Mahindra but it wasn't easy, Mahindra wanted him to buy the pin it fits into along with the zerks. I was just over there looking for more since I'm down to a few extra for our tractor (4540) and the backhoe.

Is the sizing of the zerk (ie. "6mm") the diameter of the threads or the size of the orifice through which the grease passes?

My not-so-local dealer found some zerks at $4.99 each. I told him to hold off as I found some 1/8" NPT zerks that appear to work just fine, if a little longer. The threads appear consistent with the stock zerks.
