How to plumb in the hydraulics

Yes? mainly the yanmar without sub frame loaders.. or ??

</font><font color="blue" class="small">( who'd ever say always or never.? )</font>

This didn't clarify the question I asked very much.?? /forums/images/graemlins/confused.gif

Like I say.. I haven't been around any yanmar with loaders.. so i don't know how they hold up in comparison to other tractors that do not use loader subframes...

Noted. I had it about 20", now at 15.

</font><font color="blue" class="small">( You might consider using two weld on tabs at each cylinder/frame junction instead of the single tabs pictured in your design. This has a few benefits:

1. Allows the use of thinner material for the tabs. Easier to fabricate, less expensive material, but you do need twice as many.

2. Moves the strain point from the middle of the frame tube face out near the edges. Concrentating a force at the middle of a tube face could cause it to deform and lead to a structural failure. Two tabs alow this force to be applied to the edge of the tube sides which is a much stronger arrangement. Depending on the tube used, you may also be able to weld the tabs to the side faces with an overlapping joint which is stronger than the butt joint used on the single tab design. Even if both tabs were welded with a butt joint, the weld surface area would be nearly double that of the single tab making it much stronger.
3. The use of a single tab can allow the cylinder to move in more than the designed axis, especially as the single center tab becomes worn. Under load, this can lead to excessive cylinder and seal wear and in the worst case, a cylinder collapse(fold/bend). A tab on either side of the clevis attachpoint will restrict movement in all but the intended axis.

The clevis on the cylinder may be set up for a single tab in the middle, but it works just fine with a tab plate on either side. How many production loaders out there are using a single tab for the cylinder attach points? )</font>

All makes good sense to me. I am redesigning with your suggestions.
