There is one on my Cub 129. They should all have one, but that does not mean they do. You can always put one in.

I think it would be a good idea to be able grease the axle pivot. Just make sure where you locate the zerk fitting it doesn't interfere with the pivot of the axle. Remembering to grease said fitting is the next hurdle. :say_what:

 

RF's have them and my 120 has a grease zerk on the pivot.

 

my gravely has one!

 

Larry, some people will drill a hole down through the pivot bolt and then cross drill it at the correct spot(between the bushings) and install a grease fitting on the bolt head. That way you are not drilling and tapping cast iron. You could also drill the axle as well. Worn bushings and slop in the front axle are common problems on the 300 series. You can adjust out a lot of it by tightening the pivot castle nut until the axle just starts to drag when it pivots. This will help the new bushings last longer. It needs to be checked periodically to make sure it's still tight. A grease fitting should have been on the axle from the factory.

 

Good point, Larry. I'll do that to mine this summer. Another ?. Is the axle cast iron or cast steel?

I like the idea of the zerk in the bolt if it wouldn't weaken yhe bolt to much . I know it would be easier for me to drill the axle though .

A decision to be made , I do have a small drill press so I might be able to do it . I think will expermint on another bolt first. I agree that it should have done at the factory. I've seen a lot of things done in field that the factory should have done called supplements (after thoughts ) that people like us have brought to their attention.

Thanks for the input guys

Mike I believe the axles are cast iron.

I've drilled the bolt on some tractors, easy to grease from the front! ~~ Lowell

 

Ok. I practiced on an old bolt and done ok.
So I drilled the pivot bolt , put a zerk in it installed the axle and greased and works great.
Although a person could drill the axle with out taking the axle out and install a zerk in it if they wanted to .

Thanks Larry for posting the info., I will have to check mine out and see what i have.

After I got to thinking about this, I've done both the axles & bolts on different tractors! Both ways work fine. ~~ Lowell

 

I'll be doing my 317 axle before it goes back in. Bought some fittings the other day. I need to get the king pin mounts reamed out and bushed at a machine shop as they were worn about 25 thou.
