As for the installation of new parts after replacing the synchronous belt and taking out the old parts, it is required to clean the relevant parts of the transmission mechanism first. After the areas involved are cleaned, install the components. Otherwise, sundries may be mixed in, causing abnormal wear of the installed synchronous belt. In terms of cleaning method, it is generally to wipe with a small amount of non-volatile liquid with a rag, instead of soaking in the detergent or brushing the synchronous belt with the detergent. Of course, it is not allowed to use sandpaper to wipe or use sharp objects to scratch the timing belt and its installation contact surface, otherwise it will cause wear during cleaning.
In this way, after doing a good job in cleaning, the cleaned parts can be dried before starting specific installation operations. When installing a new synchronous belt, it is very important to check whether the pulley is linear and symmetrical. After confirming that there is no problem in this regard, the installation operation can be carried out according to the procedure reverse to the old synchronous belt removal.
