RS2 water pump pulley group buy

[terrybullwon]

Is the shaft diameter the same on 3B and ABY/ADU pumps? If so, I'd take one to fit to a 3B pump.

I'll confirm this before making a batch. Guess I'll buy a selection of water pumps

I could be wrong but you may get a problem with dissimilar metal corrosion if you use an alloy pulley on a steel shaft? Obviously anodizing should avoid this, just avoid leaving it bare alloy.

Good to see someone addressing the NLA and extortionate heritage prices.

The adjustable cam wheels most people use on there motors are aluminum and the cams steel but they are locked with a Woodroof key. It's a good question.

What difference of ID/bore will be between aluminum and steel part?
Regards,

its the same product no difference

If my "imagination" works at this moment using adu wp with any(except adu) i5 20vt cams/sprocket and any belt length(that will tension ok)will get timing half tooth to the left.Because wp sprocket diameter dictates camshaft timing.Not the belt length.

I am pretty sure as you are not changing the 1:2 crank shaft to cam shaft ratio it's not going to effect it? I have a citroen water pump on my motor and that has even less teeth. Some one more qualified like JP maybe able to give a better answer

In theory it wouldn't matter if the camshaft pulley was on then moon and the crank on earth, the 1:2 gear ratio remains the same regardless of belt length.

I could also be interested in one fitted to a 3B pump, I have a new spare sat on the shelf if you would like me to take any measurements and I have an old spare you can have for R&D purposes if required

I would also prefer steel.

I'm in as well for a pully it would be for a 3b water pump . Just the pully or with a water pump attached wouldn't really worry me as I could fit either. I was thinking about this recently if the diameter of the water pump pully is reduced could you not just in crease the diameter of the idler pully by haveing a press on ring made and pressed on then the same cam belt could still be used .

Maybe we should start a list, to get a better overview of the interested people?!

1. Kryptonite 1x steel

Good idea looks like there is enough to make at least a batch of 10

Correct

[SteveH]

I'd take one if you can do something for the 3B. Don't mind what it's made of.

[kymi]

I'd take two at least. Aluminium preferred. With or without a quality pump for adu.

[vti2]

Me too

[terrybullwon]

Right.

I have the quote on the table. To make it viable i have to do 20 of.

I facebooked PKM today, Peter knew who i was from selling the crank shaft pulleys and understandably would not let me know the price of his items. He was alittle worried that i was going to copy his. I really do not need to do that with a OEM one in hand from another forum member.

I can offer them in EN8 alittle less exotic than the timing belt pulleys. Still more than strong enough for application.

With OUT the 4 drilled and tapped M6 bolt holes £80

With the 4 drilled and tapped M6 bolt holes £95

Now i dont know where this stands in the market but thats what i can turn them out at

[SteveH]

Forgive my ignorance, but where are the bolt holes on the water pump pulley?

Pulley i had been sent had them on the front face. Maybe for some kind of locking tool?

[SteveH]

Interesting, I've not looked at the 3B water pump pulley for some time, but I don't remember it having any holes in it. I can't imagine what they would be for either? Did you ascertain whether the 3B and ABY share the same shaft diameter?

Pump i have here swapped over fine.

I am going to order a Euro's one and check that

[denniselbows]

I've never a rs2 water pump but have 2 3b water pumps on a shelf collecting dust neither of them have any m6 threaded holes in them . Don't see any need for the holes, perhaps some one drilled and tapped them to be able to get the pully off a old water pump. Am I wright in saying the rs2 water pump is nla. If so some one could be thinking a head and use the pully on several water pumps .
