To do this, disassemble the parts by removing the spiral pin, bevel gear and first bearing and releasing the drive dog spacer. 3 With a 240 grit sanding pad on a flat surface, use circular motions to lightly relief the face indicated by a minute amount. Repeat on both sides. Remember to only take a small amount of, generally 4 rotations will suffice for safe adjustment 4 Reassemble and check fit of spacer. If its still to tight, repeat above step 5 If the spacer is to loose, the spiral pin may have distorted on assembly. To adjust in this instance, the following is required. Use the press and place the assembly vertically , and using the press apply pressure in the direction shown to help centralise the roll pin 6 If the bearings do not require bearing fit, move to next step. If bearing fit was loose, disassemble components and reassemble with smears of bearing fit for bearingsle with smears of bearing fit for bearings +

- The following points should be observed an … The following points should be observed and checked to achieve the optimal setting A There should be as minimal backlash as possible between the two bevel gears. To check this, hold point 1 by hand to stop rotation and rotate point 2 left and right to check backlash. B Gear high spots should be checked for by rotating point 1 and making sure sure rotation is even and consistent, with no tight spots. C Face 2 must be a minimum of 1mm from face 1. If not interference will happen when mating gearbox to drive unit All of these can be adjusted by moving the depth of the 2nd bevel gear assembly to find the optimum point to hit all the above important criteriant to hit all the above important criteria +
