Must say it’s a fairly heavy little nugget of a thing unpacked just now, hopefully heavy means quality to get me temporarily back up over the massive mighty 60rwkw mark it mite
FWIW: Do NOT pull the little rubber bungs out of each end to blow test the inbuilt one way check valve …….it’s full of factory packaging oil and now all over the kitchen table…….idiot MB style
Interestingly within the installation instructions it suggests the optional Holley 12-810 Oil Pressure Safety Switch (petrol applications) to cut off supply when oil pressure drops below 5psi which I never knew such a safe guard existed:
Thinking that when I’m finished with it and when time comes to properly fix up the old TD42 I might switch it over to the Daughters TB45 as whatever elecy pump is under its floor pan currently sounds like a million Bees buzzing and I’m not confident She’ll keep a proper eye on OEM dash warning lights
Again, I really do appreciate your advice Craig, John, Ross, Mark, Andy, Phil & Mat Mates
Your helpful posts have not fallen on deaf ears and I will build plan on a Carter pump in the future along with other TLC power upgrades Old Grandpa Spec deserves in the future.
FWIW (record keeping) :
Will fit the baby lift pump this week but did replace the $110 Zexel IP shutoff solenoid Friday morning before a quick weekend away up the mountains.
Wacky own theory was for ruling out any slight chance of it possibly jamming say half way but didn’t appear once removed to have any spring sticking point tested even with near 30 YO wear marks
FWIW2: An absolute nightmare of an OEM design swap over whilst the IP is on the truck, an expected 15min job turned into over 2hrs
That’s exactly what it needs John Mate
A 15/16” open end spanner head cut off with a 1/2” drive socket connection for a long extension drive up top above the intake manifold would make life shiploads easier next time
The 24mm I found slightly sloppy on it and kept trying to butcher the thing on the angle I was on initially, changed over to the 15/16” and was snug as
Definitely can’t fit a ring spanner over it as is next to zero room on the back side unfortunately.
I ended up undoing the banjo on the hardline so I could lift it slightly to get the open ended spanner onto it at 90 degrees but then also had to remove 2 of the 3 accelerator cable mounting bracket bolts so I could swing it out of the way for quarter turns at a time.
Had to look up the names of them both Thanks Legends (McGoggle images for me :-) but do agree both of them Top Tools Gents could definitely be modified to get the job done next time for us all for sure
As best as I can remember my nuffy In situ removal/replace seen no way of any ring type socket spanner that had beyond say 180 degree grip/wrap being able to overlap connect due to the pump’s top/side proximity on approximately 120 degrees of its circumference maybe?
Another issue found when trialling a standard ring spanner intially was that the + connection atop of the solenoid wouldn’t allow a ring to slip over due to its head room from pump casting also if that makes sense?
All I can say is that Mr Nissan (Injection Pump Division) back in the day never considered some poor Aussie Bloke/Sheila trying to remove and plug with a bung one of the few only things things that might stop a TD42
“Carry a spare & a speciality McTool” that we can hopefully develop here Old School 4.2 Diesel Stinker Legends
