8.2 REPLACING THE AIRBOX HOUSING SEAL
To replace the airbox housing o ring seal follow the steps below:
1. Open airbox and duct clamp (ensure no air pressure is in the airbox be-
fore doing so, opening the airbox under pressure would likely cause inju-
ry)
2. Remove the cable guides, cable seals and duct seal as required.
3. Take cord seal out of machine, the cord seal is not glued but may need
to be pulled firmly to remove from groove.
4. Cut length of 3mm O - ring seal slightly larger than required.
5. Stretch the seal and push into groove.
6. Let the seal rest for a few minutes, the O - ring will shrink a little in length.
7. Cut the seal ensuring that no gaps will be between the cord seal and ca-
ble/duct seals.
8. Repeat steps 3 - 7 for other half.
8.3 CHANGING THE CABLE DRIVE BELTS
The machine is fitted with standard belts; tests have shown that these belts give a good compromise of life
and grip.
There may be circumstances when a belt with much higher grip will be needed. If, for instance it is neces-
sary to install a cable, which will sustain crushing damage when light compression forces are applied to it.
It will be necessary to use a belt with a surface coating with high friction characteristics. This will allow the
cable to be pushed with high torque while being compressed lightly. Additionally, smaller cables may re-
quire a belt with a smaller groove profile to gain the best grip possible. If these types of belt are needed the
GMP sales office will be able to advise on part numbers etc. To fit these belts it will be necessary to re-
move the standard belts, the procedure is as follows:
1. Remove the guards which is done by removing 2 hand knobs and 4 screws and washers re-
taining the belt guards, see image below.
2. Remove nylon belt guide mounting bracket, see section 8.4.
