Hi Rob The measurement of the oil pump shaft that I removed from the failed FJ engine measures 14.15.
The spare oil pump shaft I have measures 14.20 Sitting them side by side they look identical.
The main pump body of the pump removed from the damaged FJ engine has a part number 7409385
I do have another pump body it has a different part number 7400883. My spare oil pump shaft doesn’t fit this body or the damaged FJ engine pump body.
I did notice that the pump out of the damaged engine when you look down from the top Where the two pump gears sit at the bottom, the one out of the FJ damaged engine is pretty flat with the casting where the two gears sit.
The spare pump body 7400883 I have that area is is raised.
Measuring from top of pump to bottom of where the gears sit The damaged FJ engine pump part number 7409385 measures 25.51 The spare body part number 7400883 measures 25.17
This engine had a previous failure the tongue from the dizzy that drives the oil pump sheared off. Also when I stripped the oil pump from the damaged FJ engine their was no gasket between the two half’s of the pump as per the FJ manual.
Looking in the FJ manual the pump out of the damaged FJ engine I am working on is as per the manual it has the same Pressure relief valve set up as per the illustrations in the manual.
Hi Can anyone assist with a good set of oil pump gears for grey motor in a FJ. I have a gear set from a grey motor L block but the shaft diameter seems to be Bigger.
