I have a 74 champion motor grader and the hydraulics won’t stay in place?? What might the problem be ? What to check??
You had already asked but the answer is the same. The inner seals of the hydraulic cylinders is the most common reason. What specifically doesn't stay in place? A good hydraulic shop may be able to match them. If not contact Elvaan Equipment Solutions in Canada. They specialize in Champion and Volvo graders.
