Front Rockshaft on a Handlift

[jeppen]

Hello - I need some bushings for my front rockshaft. I have seen that there are some bushings available but they typically are for rear rockshafts. Are these bushings the same for both front and rear hand operated rockshafts?

Thanks,
Jeff

The bushings are the same for the front and rear hand operated rockshafts. However they are different than the rear hydraulic operated rockshaft.

Great! Thanks - anyone have a recommendation on a good place to buy them from?

Thanks,

You may be able to get them from Barnyard. I bought two new pairs of them (enough for my front and rear rockshafts on my manual lift) from last year and they are great! They are made of acetal plastic and show no wear whatsoever.

Unfortunately, I am currently out of the manual ones.

OK - Does anyone know of a good place to get them? I would really appreciate the help!

I did an exhaustive search a while back and Barnyard was the only source of supply that I know of. Barnyard, are you planning to have more made? If not, I may go with my original plan and make my own simple mold.

If necessary to fabricate your own, use Ultra High Molecular Weight (UMHW) polyethylene, black color if you can get it. The UMHW is almost as slick as Teflon but has greater tear resistance and greater weight-bearing capability. All polyethylenes are subject to ultraviolet degrade. The black is much less prone to degrade.
I do not have a manual lift setup for Cub and am basing the suggestion on the fact that acetyl seems to be acceptable. I have no experience with the manual lift.

I can look into it The way the mold is made, you have to make one set of hydraulic bushings for every half set of manual ones. That means two sets of hydraulic bushings would have to be molded in order to get one set of manual ones. The company requires a minimum amount of 100 per order plus a substantial set up fee on top of the per piece fee. It would be quite expensive to set it up for just few. There is a plug in the mold that blocks the back half where the manual bushings are formed. Because there didn't appear to be a big demand for the manual bushing I had the company leave the plug in except for the last forty runs. The mold will only make one set of bushings at a time, or one and a half sets with the plug out and one of those sets will have to be hydraulic ones. Due to the amount of hydraulic bushings on hand, I would have to order another large quantity of hydraulic bushings just to get a small quantity of manual of manual ones.

To achieve the strength required for these to provide a long life the plastic has to be injected into the mold with 100 tons of pressure holding the mold together to keep it from separating.
