It seems to be a way to preserve the pump shaft spline or the engine when something locks up. As many guys on here have mentioned, BOBCAT has accomplished the same level of protection by using a belt to couple the hydraulic pump(s) to the engine. I think belts are more maintenance to keep them tight (& routine replacement), but when an engine or pump goes bad, they do not typically go bad. It really demonstrates the give & take relationship of using one part versus another.</p></blockquote><p></p>
