that works, but do you do it that way to time the engine?
I have found that it is very easy to turn the crank too much, and finding perfect TDC is fiddly.

the notch in the pulley may make it a little easier.

cool, I just put one up in the MK2 forums as well, and I might throw one up in the G60 forum too.

What about using an ALH roller like one of the ones in this picture?

well, I have a couple gasser timing belt tensioners lying around, so for the moment I will proceed that way.

but if a reverse rotating water pump becomes available, I will go that route to eliminate moving parts.

yeah, I have done extensive searching on the vortex, and the interwebz in general, and come up with nothing.

one thing that came up was to import the impeller into cad, mirror it, and then have it machined.
might be doable, but pretty costly.


the other thing is, weren't some of the impellers(maybe cheap replacements) stamped out of steel with little flaps bent inwards?

one like that would not be too difficult to manufacture with the flaps made facing the other way.

They're not very good pumps, though.

well, the general consensus os that reverse water pumps do not exist.

it is also apparent that that is plenty of belt contact to turn the water pump.

that being said, I am going to put the timing belt tensioner on the alternator bracket simply to make adjusting the belt tension easier.

If you mirrored the impeller you would also need to mirror the scroll in the water pump casting.

Good point......plus they're junk.

'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.
