Before diving into the mechanics of a "repack," it is essential to understand the value of the original documentation. The Manitou MLT 840 is a sophisticated machine. It is available in two primary variants—typically a version and a 137 PS version. While the chassis looks similar, these machines have critical variances in hydraulic flow (usually 150 l/min vs 180 l/min) and specific components that require different spare parts.
Secure the rod eye in a heavy vise using soft jaws (aluminum or wood blocks) to protect the metal.
Here are your legitimate options:

No need to modify seals or deal with improper tolerances. Longer Service Life: Reduced downtime between repacks. Conclusion
When a part fails, a repack usually includes the . Use the diagnostic charts to identify the root cause (e.g., transmission slip, low hydraulic pressure). Follow the step-by-step instructions to disassemble the assembly, replace the part (found using the parts catalog), and reassemble it with the correct torque specs.
To successfully perform a repack, you must have the correct part numbers for the cylinder seals, gland nuts, piston seals, and wear rings. Using the genuine parts catalogue ensures you receive the correct, high-pressure-rated seals. Key Sections to Locate Before diving into the mechanics of a "repack,"

The manual provides specific intervals, such as inspecting wear pads every 1,000 hours, which can prevent cylinder strain. 2. When to "Repack" Your Cylinders
completely or use mechanical stands to take all weight off the cylinder.
Slide the gland back onto the polished rod carefully to avoid tearing the new seals on the rod threads. Hone or lubricate the inside of the barrel. Push the piston assembly straight back into the barrel.
