Changing the upper belt, HTC 650/800
Changing the upper belt on an HTC 650/800 takes approx. 30 minutes to 1 hour.
NOTE! Only use rounded screwdrivers when fitting the belt.
1. Disconnect the chassis from the grinding head.
2. Disconnect the motor cable (make a note of the connections).
3. Remove the cover.
4. Remove all that remains of the old belt. Check the seals, and change if they are
damaged.
5. Check if the shaft journals are worn. On the HTC 650 and 800 (models built before
year 2000) the shaft is approx. 20 mm If it is worn more than 2 mm, the entire pulley
shaft must be changed. See pages 37-40, Changing the inner belt, for dismantling
instructions.
On the newer HTC 800 (models built after year 2000) the upper section of the shaft
can be changed. It is fastened from above with a socket head cap screw.
6. Fit the new belt by first threading it over the shafts and then prising it down over the
edge of the motor plate as illustrated in Fig 19
7. Refit all parts. The machine is now ready to be used.
