Nelsonian Posted September 19, 2013 Share Posted September 19, 2013 I just got on board and ordered one. Just before I did it stated 4 available, so 3 now or ?? Quote Link to comment Share on other sites More sharing options...
NewZed Posted September 19, 2013 Share Posted September 19, 2013 (edited) So, I've been looking at sourcing a pump from Australia... emailing a Jimmy at staparts.co.nz. My stock pump (L28) measures 66 mm from the base to the top of the flange. The pump they list as for LD28 is only 60 mm. Part number on that one cross references to a WPN-062... not a WPN-079. My hypothesis is that the 062 pump differs from the 079 pump in this distance from back to front. I wonder if just swapping out the front flange would make it 66 mm. Those just press on/off... Isn't inline6 saying here that WPN-062 is the diesel pump? RockAuto is selling the -079. From the info link on Rockauto - More Information for AISIN WPN079 Alternate/OEM Part Number(s): 2101017S25, 2101017S26, 2101017S27, 2101017SY7, 21010V0725, 21010V0726, BA01017S27 Edit - maybe the WP079 is special after all. The other manufacturers all list the same part number for gas and diesel but the WPN079 doesn't show as a gas engine option. AISIN doesn't even have a gas engine option (1978 280Z example) Carry on and good luck... Edited September 19, 2013 by NewZed Quote Link to comment Share on other sites More sharing options...

Odd feeling hoping something doesn't work right out of the box! Quote Link to comment Share on other sites More sharing options...

LanceVance Posted September 21, 2013 Share Posted September 21, 2013 Just tried it out, part no: WPN079 has the large impeller and will NOT turn without modifying the timing cover. Good to go! Quote Link to comment Share on other sites More sharing options...
Tony D Posted September 21, 2013 Share Posted September 21, 2013 Now with that kind of response lets hope their stocking system lays in another ordering bigger quantities! Quote Link to comment Share on other sites More sharing options...
inline6 Posted September 21, 2013 Share Posted September 21, 2013 Aaah! I have been moving for the last week or so and haven't been watching the forums. Quote Link to comment Share on other sites More sharing options...
Bob_H Posted September 23, 2013 Share Posted September 23, 2013 Well, just checked and it said one in stock- just ordered. Will report if not the correct one. Bobby Quote Link to comment Share on other sites More sharing options...
Nelsonian Posted September 24, 2013 Share Posted September 24, 2013 Okay, I received mine (Aisin WPN079) last week and test fitted it by lining up holes loosely into the timing cover and it fits and spins WITHOUT any modification done to the cover. It is only slightly different (extended tab) than my new polished Paraut pump. The new Aisin appears to have had something lightly dremmeled off in two places. Paraut on the left and Aisin on the right. What do I have going on here? Quote Link to comment Share on other sites More sharing options...
Gareth. J. Posted September 24, 2013 Share Posted September 24, 2013 Kinda looks like the right shape, it's a bit worrying having the grind marks on it though. I hope these are the real LD pumps I've already gone through this once before. Lol. Here's my OEM LD28 pump. Could it be off centre slightly without the studs in?

rags Posted September 24, 2013 Share Posted September 24, 2013 Nelsonian, It looks like they used the correct housing but ground down the impeller to look like a gas impeller. The diesel impeller blades overhang the back part of the wheel slightly whereas the impeller shown in your fist picture does not. Quote Link to comment Share on other sites More sharing options...
NewZed Posted September 24, 2013 Share Posted September 24, 2013 I wonder if some marketing guys have been reading the forums. Quote Link to comment Share on other sites More sharing options...
ctc Posted September 24, 2013 Share Posted September 24, 2013 (edited) Did a quick measurement on mine. Aisin impeller diameter measured 2.958" (75.133mm). It would not fit two stock covers I have. Impeller would contact the 7 o'clock area by the water inlet (?). For comparison, my stock pump impeller measured 2.741" (69.621mm) and spun freely. Mine have the grind marks as well. Looks like they ground off a previous serial number or manufacturer name. Edited September 24, 2013 by ctc Quote Link to comment Share on other sites More sharing options...
NewZed Posted September 24, 2013 Share Posted September 24, 2013 What do I have going on here? Is it possible to run the diesel L6 front cover on a gas L6 engine? Aside from the area behind the water pump, what else would be different? Maybe you have a diesel L6 cover. Quote Link to comment Share on other sites More sharing options...
Xnke Posted September 25, 2013 Share Posted September 25, 2013 That looks an awful lot like an Atsugi water pump...witth the markings dremeled off. I have a few that have casting marks in them in that spot that are Atsugi Quote Link to comment Share on other sites More sharing options...
Nelsonian Posted September 25, 2013 Share Posted September 25, 2013 According to this thread (http://forums.hybridz.org/topic/111003-preferred-water-pump-l28et/?hl=%2Bld28+%2Bwater+%2Bpump&do=findComment&comment=1038367) , Atsugi is the parent company of Paraut and was the oem Nissan provider. Could anyone else buying the Rock auto offerings post pics of what you receive. Looks like I will be returning the virtually duplicate pump to Rock Auto.

Gareth. J. Posted September 25, 2013 Share Posted September 25, 2013 (edited) Mine arrived today, impeller measured in at 69.5mm, F#$k! Looks exactly the same as yours Nelsonian Looks to me like the numbers have been ground off for a reason, the reason is this is a gas pump. I'll be returning it! Edited September 25, 2013 by Gareth.

Gareth. J. Posted September 27, 2013 Share Posted September 27, 2013 How did everyone else go that bought a pump recently, is it just Nelsonian and myself who got the wrong part? Quote Link to comment Share on other sites More sharing options...
