    Thanks for your help RJ! I’m slowly but surely getting these ZLs back going. It took me a while to get dedicated to it but it’s on now!

    Thanks for providing the support for our big ZLs

    :hello: No problem glad to help. :notworthy:. Run your bike before doing anything. If the water pump just leaks oil. Then just replace the oil seal. Also check the propeller for play. Put the pump in a vice. Rotate the propeller with your fingers to check for tight spots. Then with both hands one on each side of the shaft & try to wiggle it side to side then up & down to check for play. This checks for bad bearing. Most of the time the bearing closest to the propeller wears out. I have all the OEM water pump part #s listed in this thread for a complete overhaul. I have 12 of each OEM part in stock. I also have the size of the oil seal listed.

    I had sent my old and busted water pump to RJ. He did super work. Pictures are the water pump before, still on the bike. After the rebuild and all the parts RJ sends with the NEW pump. Getting it all back together now. Will update after riding awhile, doing a few burnouts and a smoky, front wheel raising, holeshot.

    My old dog is marking it's spot on the basement floor. I was hoping it was a loose bolt from my oil pan replacement but after some inspection the is oil and a drop of coolant on the bottom water pump bolt. I'm guessing life expectancy is 16-18 years since I replaced it with a new one way back when. Damn, I just did the coolant and all the hoses last year.

    R.J. send the ship to and total so I can include a check with my old pump.

    :hello: Jeff from Minnesota sent me 6 water pumps to rebuild along with a few parts. Two are for Jeff and two are for David. If anyone needs one let me know. I'll rebuild them late this week. I also have 7 more to do. I'm not sure of their location. :laughing7:. ____________________________________ IMG_9008.JPG IMG_9009.JPG

    :hello: I started tearing down some water pumps today. 9 in all. Time spent 3 hours. I have 6 more but I can't find them. I can't find the OEM oil seals that I have in stock either for the ZL 9/10 pumps so I ordered 6 more oil seals from partzilla. 6 is all they had in stock. They will be here late this week.

    :hello: I sand blasted all 9 water pump propellers and shafts then polished all the shafts. Then installed the ceramic disk onto all 9 shafts and seated them into the propellers. Next I installed the inside bearing in all 9 pumps. For 5 pumps I installed the mechanical seal, the propeller/shaft, outside bearing and the C clips. 1 pump I installed the oil seal. The OEM oil seals will be here Friday. Time spent 4 hours. ____________________ IMG_9083.JPG IMG_9084.JPG IMG_9085.JPG IMG_9088.JPG IMG_9110.JPG IMG_9114.JPG IMG_9096.JPG IMG_9097.JPG IMG_9098.JPG IMG_9099.JPG IMG_9100.JPG IMG_9102.JPG IMG_9111.JPG IMG_9112.JPG IMG_9116.JPG IMG_9104.JPG IMG_9106.JPG IMG_9105.JPG IMG_9107.JPG IMG_9113.JPG
