Casale Split Case V-Drive Disassembly Procedure with ball bearings
Last Updated: 07/09/2017
Step 1. Remove the top bearing cap from the back side of the V-Drive
Step 2. When the cap is removed, you will see a bearing with a snap ring groove in it. Warm the V-Drive case around the bearing with a torch. Using our bearing puller, insert it into the snap ring groove and pull the bearing out by using the jack screw in the center of the puller, and pushing against the center of the shaft
Step 3. When the bearing is removed, you may take the back half of the V-Drive off by removing the ten 5/16" bolts that hold the front half and back half and the mounting plate together. Use the jack screw in the center of the lower shaft bearing cap to remove the back casing.
Step 4. When the back half of the V-Drive is off, remove the bearing spacers that rest on top of each of the gears in the V-Drive.
CAUTION!! DO NOT MIX UP THE SPACERS AS THEY ARE NOT INTERCHANGEABLE
The thicker of the two spacers goes on the lower shaft; the thinner on the top shaft.
Step 5. When the spacers are removed, remove the top gear first, then the lower gear,(which normally is the tapered gear). You now have the gear box disassembled and are ready to install another set of gears.
If the tapered gear is on the top reverse the procedures.
FOR COMPLETE DISASSEMBLY FOLLOW ABOVE STEPS AND CONTINUE BELOW
Step 6. Remove seal caps on the front half.
Step 7. Support front half from the inside of case on bearing boss and press out the top shaft from key way side of shaft. The lower shaft should be taken out by pressing on the splinted end.
Step 8. Warm the front half with a torch and drop out the bearings.
THE V-DRIVE IS COMPLETELY DISASSEMBLED AT THIS POINT AND IS READY TO REASSEMBLE
Reverse the disassembly procedures. Check to see if the V-Drive turns freely. Put an indicator in the side of the keyway on the top shaft. Rock the shaft right and left while the bottom shaft is being held stationary. Total indicator reading for backlash should be .008 to .010
FOR MORE CLEARANCE:
The bottom front spacer will have to be shortened. For every .005 in thickness taken off the spacer, it will give .001 clearance. The amount taken off the front will have to be added to the back spacer.
TOO MUCH CLEARANCE:
The front spacer will have to be thicker. The amount added to the front spacer will have to be taken off the back spacer.
The bearing cap depth plus the gaskets should measure the same distance as what the bearing protrudes from the case.
