Is a motor seal needed to remove the large cover of an XS-type single-stage double-suction pump?

Could everyone help take a look? For this type of water pump, just by opening the volute to check the gap between the impeller and the mouth ring, is it necessary to remove the mechanical seal? The stationary and rotating rings of the mechanical seal are fixed to the volute with bolts. Since this is the first time it’s being disassembled, the asbestos gaskets used in the mechanical seal can also get damaged easily.
Yes, it is necessary to remove all the screws of the sealing end caps on both sides and then take off the top cover in order to expose the rotor section
