First of all, i did not write this. I came across someone named Larry Chen on the net from the car team group-junkies who just recently did a "minor" maintenance on his datsun 240z(260, 280, not entirely sure)with the rb25det engine. All credits goes to him. I am backing up his maintenance diary here, just in case, like all the good tutorials out there goes down.Stuffs covered in this post:
- Water pump install
- Oil pump install
- Timing belt install
Day 5, Timing Belt, Water Pump and Oil Pump Install
So I cleaned up a lot of that rust compared to the discoveries I found in Day 4.
New water pumps are cheap insurance. I opted to use the Nissan N1 Water Pump.
Nissan Part Number "21010-24U27"
These studs come with the water pump. Connect these to the water pump by hand for now and come back with Thread Locker later.
I am not a fan of gaskets unless it comes to Head Gaskets and other gasket only applications.
Otherwise I used the Permatex Water Pump and Thermostat Housnig Gasket Maker for the water pump.
This is the alternator bracket that also goes onto the water pump on the two upper left 14mm bolts.
Just the backside, nothing special.
I decided to use Medium Strength Blue Thread Locker from Permatex on the water pump and oil pump bolts.
Make sure you apply your gasket maker all over evenly on the clean polished surface of the Nissan N1 Water Pump.
Torque down everything in the right order going counter clockwise from the first 12mm bolt on the bottom middle.
I love getting Nissan boxes. This particular box contains my N1 Oil Pump.
Nissan Part Number "15010-24U01"
I know you've seen this before, but it looks pretty all over again.
For the oil pan and oil pump, I opted to use a Ultra Black Hi Temp gasket maker. With no paper gaskets less surface to seal and less mess plus less error.
The oil pan to the left is all prepped up with Gasket Maker.
Torque all 10mm bolts to specs
Two pumps installed cleanly.
Clearance on the Oil and Water pump is tight, but Nissan did hell of a job designing these two parts.
Like I had mentioned, this install we will also be doing a timing belt on my project.
It is highly suggested you change the tensioner assembly and the idler pulley whenever you change the timing belt.
Nissan Part Number for Idler Pulley "13074-58S00"
Nissan Part Number for Belt Tensioner "13070-5L300"
Yum yum yum, I love new OEM, everything is so shiny!
Notice on the bottom of the tensioner assembly that the newer tensioner (on the left), has a hole instead of a slot for the tension spring. The new Idea on the hole instead of the slit makes it easier to install the tension spring with no problems.
The marks on the old idler pulley doesn't matter since it is purely because it doesn't spin like you would think.
Drop the belt on with the lines marked up looks pretty awesome.
The ATI Damper works for all kinds of RB motors, check it all out.
