Cylinder Tester
This guideline will enable dealers to test double acting cylinders and extension cylinders. The 188-3926 Caterpillar Cylinder Tester or 9U-6803 Caterpillar Cylinder Tester is used to perform the tests. The function of the cylinder tester is to conduct a leakage test of piston and rod seals in resealed hydraulic cylinders.The test of whether piston and rod seals are resealed is determined in two (2) ways:
By watching the rod, piston drift, and external leaks at the rod. The seals will leak and cause the rod to drift if the wrong piston seals have been installed. Also, check to see if the seals have been "cut" during assembly. Damaged seals will also cause drifting or leaking.
By watching the rod, cap (and head) end, and gauge readings. If the pressures hold, piston and rod seals are resealed, the test was effective. If the pressures drop and equalize, a leakage path exists either through the seal or past a scratch in
