SleeperZ Posted September 14, 2012 Share Posted September 14, 2012 I'm saying the impeller is the larger one, and the casting is the LD28. Look at the impeller clearance to the casting, especially the short center section, the L28 has significant clearance where the diesel unit has minimal clearance. No doubt in my mind.

Zmanco Posted September 14, 2012 Share Posted September 14, 2012 The shaft hole measures 11.9 mm across. Quote Link to comment Share on other sites More sharing options...
NewZed Posted September 15, 2012 Share Posted September 15, 2012 (edited) Wouldn't the impeller diameter be the number that matters? The diesel impeller is larger diameter? No need for eyeball estimates then. The RockAuto picture looks like a gas impeller in a diesel housing. To my eye. Taking parallax and other photographic distortions in to account. Edit- maybe this guy can take a measurement... Edited September 15, 2012 by NewZed Quote Link to comment Share on other sites More sharing options...
Gareth. J. Posted September 15, 2012 Share Posted September 15, 2012 The best test would be trying to fit it into an L series timing cover, wouldn't it? Looked identical to my Nissan atsugi LD28 pump. Quote Link to comment Share on other sites More sharing options...

Z Fire Posted September 28, 2012 Share Posted September 28, 2012 Got one ASCO water pump from Rockauto yesterday. Housing is definitely LD28. Impeller outer diameter is 75mm vs 70mm on standard L28 Nissan pump. Quote Link to comment Share on other sites More sharing options...

EvilC Posted October 18, 2012 Share Posted October 18, 2012 To bring this thread back - recap: You guys that have ordered from rockauto within the last two months have gotten diesel L6 water pumps. Besides looking and measuring, you have placed them in a timing cover and CAN'T spin them freely? Quote Link to comment Share on other sites More sharing options...

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...

Xnke Posted December 13, 2012 Share Posted December 13, 2012 Or just machine a spacer 6mm thick... Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted January 24, 2013 Share Posted January 24, 2013 I figure I will eventually be able to buy a pump for my LD28 from one of you guys when it sits in a box for 2 years. Quote Link to comment Share on other sites More sharing options...
Chris83zxt Posted September 17, 2013 Share Posted September 17, 2013 You guys are awesome. Rockauto has them back in stock (only 9 now after my order). I should have mine soon, and I'll give everyone a heads up if anything has changed with the part since last year. Quote Link to comment Share on other sites More sharing options...

Hopefully these are the true LD pump, keep us informed as you'll get yours well before I do down here in Oz. There was only six left when I ordered.

I know there's a tendency to keep stuff like this hush-hush due to fear that the supply will completely dry up, but on the other hand if we show there is still demand (which seems to be happening right now) hopefully they'll keep (re)manufacturing the parts Quote Link to comment Share on other sites More sharing options...
