Hi

I found Rob M 's reply in the following thread good enough to help me strip and lube my Hurricane.

Mine was just over 2 ftlb. When I stripped it I found that the piston washer was a tight fit in the cylinder so I gently sanded some off till it held in place with a finger on the transfer port but slid down when pressure was released. When I got it back together it was a much healthier 3.6 ft/lb.

Good luck
Zyg
