water pump - what fits/swaps

[hang_510]

i need a Z24 waterpump (maybe not a Z24 pump :confused: )

anything ive searched for all have fan clutches which i dont need(or want)

 

the L pump i have physically fits on the cover.

 

who knows if the L pump would function correctly in the Z cover???

 

 

another dilimma i have is the centering nipple. the Z is ~1" wide where the L ~1/2" so this messes w/ my fan set up (ill change it to what i end up with though)

 

 

what else can i cross reference?

 

id like to put an atsugi back in but all im finding are BA or cardone remans

[datsunaholic]

They work... the pump body is exactly the same.

just an early l16 pump. sans clutch

paraut water pump:

part# V3-003

I paid $35

 

Made in Japan, box says Laurel (z18s) Skyline (z18) Bluebird (l18)

[banzai510(hainz)]

I know the 240x one had different screw holes than the 510 one. so my 510 pully would not fit on the 240z pump unless I found a 240z pully

 

did you try importedcarps.com or Mr-auto-parts.com

 

Mine was a atsugi in a Paurut box if I remember right

:w00t:

thats what i was hoping.

 

looking further, the 810 and 240Z (L24) seem to have the larger centering nipple and the same body(they use the same gasket...)

 

the pulley also falls under the issue, but i have have both, so 1 will work.

 

thanx!

 

 

 

any input on GMB? thats what mr.auto.parts has as from japan.

 

AND what is better, cast or the bent steel vains???

[kiznook]

touche! it is in fact Atsugi in a paraut box. The instructions that come with it are awesome too. I'll have to scan them, the cartoon water pump pictures are too awesome

 

"Insert the stumpy driver into the attatching bolt hole, and move it up and down for removing the pump"

Brian, If you plan to run electric fan and don't need the clutch fan, just cut it off. The pulley is pressed on and will be fine.

[hang_510]

thanx mike, i saw you had done that

 

problem w/ that option is the new pumps are ~$90 vs $20-30 for the non-clutch

 

using a mechanical(stock plastic 4 blade :lol: ) fan

 

 

 

 

what is better, cast or the bent steel vains???

[datsunaholic]

I prefer the cast ones, but they're getting very hard to get now. I've seen cavitation from the stamped steel ones (I've had those fail dramatically too)

[hang_510]

thats why i asked, my stamped had 1 blade that had dissolved :eek:

 

guess ill get 2 then

[banzai510(hainz)]

I have used the GMBs (stamped metal)before and had not real proplems with them.

I guess my front cover cavitating and putting a hole in the aluminum (My 521)was due to more or less not having enough antifreeze.

see the first part of my vid. notic the holes ,look like a termite went thru it. The front cover was good!!!!

Get the Atsugi brand if possibel,it was stock on most datsuns that I seen.

 

I heard from a racer you can put cut a V into the vains so it doesnt cavitate as much. Cant verify this or not but is a option if anybody wants to try it.

 

I got my last pumps from Mr-Auto-parts.com. should say atsugi /Paraurt or whatever it is.

I buy 2 of everything so I havent order thru most of these sites in a long time. Some might even be NLA

[hang_510]

update: the pump bodies are matched and do bolt right in, unfortunately the 'nose' is not.

by about 3/4 the thickness of the belt...unless i could find an equally off-set pulley i used what was on there before...

 

ended up w/ a cast vane pump for early L28 turbos (these dont have the fan clutch attached) which also has the larger centering nipple.

 

works like it should :cool:

 

 

and since it came w/a lifetime warranty, i now have a spare ;)

True, but the vanes on some are taller? and recessed into a deeper cavity in the body and must move more water. I've got a few Z20 ones and heard that they flowed more water. They do look different.

That's why I'd rather have a used cast one, than a cavitation special

[hang_510]

depth of the blades was very close between the pumps, the nose extended just a bit more, enough to not work w/o another tweak. the cavity depth of the covers (L16/L18/L20 and the Z24) also measured within a mm of each other.

 

the cast have the vanes laid out differtnly too (not a fluid dynamic kinda guy) but from the water pumps ive used (aquariums) the opposed blades(cast) allow the fliud to flow more smoothly.

[datzenmike]

I'll try to get a picture of them. The vanes all stick out (into the timing cover) the same distance but some have a deeper cavity in the pump body with coresponding larger vanes.
