BVV Butane Recovery Pumps Top Dead Center Calibration Plate & Bolts
Use with the Top Dead Center Clearance (TDCC) instructions
Use this plate and a depth gauge to measure the Top Dead Center Clearance of the piston/cylinder/head assembly. Shims that come with the piston cylinders are stacked to create an area of displacement between the top of the cylinder and the compressor head.
BVV's Recommended depth is 0.012" for the BVV 4 & 2 Cylinder Butane Recovery pumps. This gap is recommended for optimum recovery performance.
