A cover for a pump jack includes a main rear wall with two slots for engaging over a pair of shafts of the pump jack at the drive belt on the pulleys on the drive shafts. The rear cover portion includes a peripheral wall extending around the sides and top of the peripheral edge with the bottom of the cover panel being opened. A front panel portion manufactures a single piece or as multiple pieces fits over the rear cover panel with a lip engaging onto the peripheral wall to which it is connected by latches. A stiffener member extends across the rear wall and closes the slots. A similar stiffener member can be attached across the front panel portion. Both the rear panel and the front panel are manufactured from glass fibre reinforced resin allowing the product to be manufactured in lightweight. The front cover panel can therefore be readily removed to allow replacement of the belt.
