allparts.jpg (12575 bytes) These are all of the parts, more in less in sequence that are part of the water pump
seal.jpg (16118 bytes) This is the seal that needs to be purchased from a Honda CX500 Turbo, part number 19217-657-023
bearings.jpg (15370 bytes) These are the two SKF 6000 2RS JEM bearings - get these at a bearing supplier
step1.jpg (13074 bytes) Step 1
Start with the 'empty' impeller and shaft
step2.jpg (13437 bytes) Step 2
Place the ceramic part of the CX-500 seal onto the shaft and into the impeller
step3.jpg (15664 bytes) Step 3
Place the larger of the two spacers over the shift - it will slip into the impeller
step4.jpg (14778 bytes) Step 4
Place the second part of the CX-500 seal (the mechanical seal) onto the impeller shaft
step5.jpg (12823 bytes) Step 5
The completed impeller work should look like this
step6.jpg (14861 bytes) Step 6
Start with the water pump housing
step7.jpg (15030 bytes) Step 7
Tap one of the bearings into the housing
step8.jpg (17794 bytes) Step 8
Tap the tin cover over the bearing - I'm not sure what's best here - it might be advisable to install the impeller shaft at this point - that way a person could get socket or other 'deep' tool onto the inside of the bearing and hammer where it puts the least stress on the bearing
step9.jpg (17065 bytes) Step 9
Place the smaller of the two spacers into the pump housing
step10.jpg (18633 bytes) Step 10
The completed pump housing will look something like this (with the spacer inside)
step11.jpg (18925 bytes) Step 11
Tap the other bearing into the pump housing
step12.jpg (15882 bytes) Step 12
Tap the impeller shaft through the pump housing - see note on step 8
step15.jpg (15910 bytes) Step 13
Place the clip over the whole works
step14.jpg (17569 bytes) O-Ring, 37.2 x 2.3 on one part of the water pump
step13.jpg (13076 bytes) O-Ring, 56.0 x 2.4 around the outside of the pump
