Hi I am wondering if you must run an axle pulley for a leopard water pump, I don't have one and was wondering if its ok to run the bands straight off the axle. They want about $60 for a pulley, $170 for complete pump and assembley, which is the way I was going to go and have a spare pump but just read that the leopard pumps are useless. So whats my best option. Cheers

You don't need a pulley in most cases when you're running a 50mm axle.
What about 40mm axle, running Tag R
Hi Rick, I don't know much about the 40mm axle and a pully but my mate is not using a pully with his 40mm axle and he seems to be going okay in TAG restricted Heavy. On the water pump issue. I have a plastic pump and just after I started running it with my Leopard it started leaking and a bearing seized. I found that the seal behind the impella was a loose fit in the pump housing as well as the bearing next to it. I fixed it by going to my usual bearing supplier and he found an imperial seal and bearing which had the same ID measurement as the originals but had a slightly larger OD measurement, around 0.2mm. The pump has been working ok for about the last 18 months. My karting budget is limited too, so if I can fix a thing, I will. Regards, Max.
Thanks for the Info Max, much appreciated.
