The owner shows accessing the relief valve on the hydraulic block, removing the plunger and spring, swapping shims, and reading pressure with a gauge at 2000 rpm. Useful for owners considering this modification, but it's an unofficial tweak that voids warranty and carries acknowledged risk.
Posted by the BotaTrac channel, an owner performing DIY modifications on his own L2501 and sharing the process directly.
Attach a pressure gauge, remove the relief valve plug, spring, and plunger from the hydraulic block, add a shim, reassemble, then check pressure at 2000 rpm.
The dealer stated the L2501 is released from the factory with a maximum operating pressure of about 2205 psi.
Yes, the video states that raising the hydraulic pressures will void your warranty and is done at your own risk.
Pressure went from about 2205 psi to around 2600 psi, roughly 400 pounds more, about a 20 percent increase.
