Triumph Stag Water Pump & Fittings
If unsure as to the type of water pump fitted to your vehicle, the pump cover will have to be removed to check the number of vanes on the impellor (note; water pumps & covers can not be interchanged between 6 & 12 types). A water pump extraction tool (part no. RB7009 or RB7009PRO), is usually required to extract the pump from the cylinder block (or improvise!). If the pump is difficult to remove, it may leave the brass cage in the cylinder block, this may be carefully prised out. The pump spindle bush (part no. 145022), which is located in the cylinder block should be replaced as a matter of course.
