Question about hydraulic lift arm

Postby sgraber » Sun May 10, 2020 10:38 am

I recently installed the hydraulic lift arm on my '62 Cub. As I understand it, it bolts under the seat on the frame. However doing so makes the seat not level any longer. Is there supposed to be a shim that goes under the other side of the seat on the frame? Just wanted to check with those that know!

Should be shims under the low side, same thickness as the lift arm frame, and longer bolts. A few washers would work.

I don't see anything shown in the parts manual. I would either find a piece of steel the same thickness as the rockshaft bracket and drill 2 holes for the bolts or find a short section of thick walled pipe and cut it down. You may need longer bolts. I'm not sure if there would be enough threads left on the original bolts with a shim.

Ed, you beat me to it.

That was the exact reason of this post. I looked through the parts manual and couldn't find anything referencing a shim so I thought maybe I installed it wrong! :-) I'll grab some metal and drill some holes through it to make the shim. Thanks!

By the time the deluxe seat came along, they probably weren't expecting that much need for the older style rear rockshaft. I don't think anything specific to that combination ever made it into a Parts Catalog. I never saw instructions for the rockshaft new enough for a deluxe seat to be mentioned.

Mine is set up the same way (crooked). It's not even noticeable. I agree that a shim and longer bolts would solve it, but from many hours of experience, I can tell you that it doesn't really matter from a comfort standpoint.

That said, after looking at your photos, the seat frame on the low side seems like it has rusted thin. On one hand, you might want to level it to take the horizontal stress off. That might help keep the metal from breaking. On the other, getting that low side off in the first place might be dangerous to the integrity of what's left of the seat frame.

That's exactly what I did. :) It was a bear to get those bolts loosened/removed as they were really seized though! The new bracket is primed and will be painted this spring.
