Add a zerk?? How to...

Highbeam · Apr 25, 2006

It looks like 8 is pressed into 9. If so, drill and tap a hole through 8 and 9 and install the zerc into 9. It will push grease into the gap between 8 and the shaft until grease spews out the topor bottom. I would assume that the shaft moves around enough to distribute the grease. The zerc is a tapered thread so tap it shallow so you don't end up with zerc in the shaft.

Thanks Rob, that looks like a good process. I'm going to try a couple shots of silicone before I mow next time, and if it doesn't get better then I will install the grease fittings.

Highbeam is right if 8 and 9 are press-fit together, basically what I suggested. However, even if press fit, it would be wise to run a groove around 8 anyway in case...for some reason it rotates and shuts off the hole in 9 (Murphy's Law). I'm a firm believer in Murphy's law, in fact I think he was an Optimist.

On the zerks...Napa has a whole selection of them...straight, 90° and 45° bends...etc. Also you can get them with 1/4"-28 threads or tapered 1/8" NPT or even Metric threads. Use whatever you have to tap with. I like using the 1/8" NPT tapered for exactly the reason Highbeam pointed out.

Rob:

You'll never make a good farmer. Good farmers NEVER grease anything. Good farmers DON'T own a grease gun either. Good farmers just run a part dry and sell the implement at an auction to an unsuspecting buyer, usually... ME . /forums/images/graemlins/grin.gif
