Illustration 1. Alignment of wear sleeve with shoulder on shaft for a smooth surface.FABRICATED INSTALLATION SLEEVE: An installation sleeve can be fabricated for easier assembly of the oil seal on the wear ring. The sleeve has a longer taper for gradual expansion of the seal lip as it slides into position.
Illustration 2 shows dimensions and specifications to fabricate the installation sleeve.
LEAKAGE TEST:After the main housing and bearing carrier are assembled on the shaft, and before the clutch plates and other parts are installed, a seal leakage test can be made to be sure the seals have not been damaged. To make the test: 1. Install a rubber or cork plug in the oil filler opening.2. Remove the oil level gauge and install a hose on the gauge tube. Fasten the hose with a clamp.3. Connect the other end of the hose to a source of pressure air, with a pressure regulator (control).4. Adjust the air pressure to 14 kPa (2 psi) maximum.5. Put a mixture of soap and water around the seals to check for leaks.
Complete service manuals for these power takeoffs are available from Twin Disc Incorporated, Racine, Wisconsin.
