Comments Off on 90 Series Hydraulic Pump – Changes to Auxiliary Mounting Flange

The A Pad auxiliary mounting flange has been changed on these models: 42, 130, 180 and 250cc. All the pumps will be changed to a new arrangement.

The older units used a large cross section o ring. The groove in the flange will have a larger o ring in it (.103″) versus what it did have (.070″). The new o ring on the A Pad seal is like a donut style with a flat cover.

All the old ones will not use the small o ring and stepped cover plate any more. So make sure you throw the old one away and use the new style. If you have a model that is not listed but similar to the new style A Pad and cover, you can use it on your unit. New part number 9004104-1520 oring
