I ordered a new 420 front bracket for my JBSR front bucket to convert it from my 318 to my 420. The JBSR never ran out of lift power on the 318, but I have noticed on the 420 that it can only lift a half bucket of dirt for example, otherwise it simply won't lift without a lot of effort.
So I started inspecting the front end, and noticed hydro fluid squirting out of the front left couplers. The O-Rings are clearly leaking. So, the question is, since these O-Rings were leaking, would that have introduced air into the hydro system of the 420, thus reducing lifting performance even though the fluid is leaking outside the system while in use? And if so, is there a bleed procedure I need to follow? Is there something on the 420 hydro system where I can enhance pressure or bleed the system other than burping the system?
I ordered 4 new JD 113 O-Rings, and I hope they hold the pressure without leaking once I install them. Any thoughts guys?
