Things are finally starting to take their final form and I should be ready for the first start up within a week or so.
I spent some time trying to figure out the AC system and the fittings I will need to gather up. Does anyone out there have any info they can share about the Cummins AC compressor? They cannot provide anything useful, what I am looking for is an adapter block to take the o-ring seal fittings to #8 and #10 male thread fittings, this way I can get stuff at my local parker store and have the hoses made locally.
Here are a few pictures of the compressor. I measured about 1.75'' center to center on between the suction and discharge port. I have dispatched an email to coldhose, perhaps they can help.
This is not my highest concern right now however. The air intake system has been a thorn in my side for a long time, in particular the mounting of this MAF sensor. Well I think I have it all worked out finally. I designed this little part that hooks right up to the 1FZ airbox top, then I can use a pair of silicone 90 degree elbows to get down to the turbo.
It was a pain because I need to keep this part as short as possible to keep the intake plumbing away from the EGR cooler, I wish I could rip that pos off. I also tried to keep as much of the Cummins geometry as possible since they already did their calibration work, this added some challenges since I need room under the sensor connector for the silicone elbow and the connector body.
Here is an over view of the airbox top assembly..
The power steering pump also came with a supporting dowel that bolts to its backside. Well I lost mine somehow. Long story short is that Cummins is not able to provide the parts since they come from some mysterious supplier, you know what that means! Gotta do it the hard way, I turned this out on a lathe. You would also think that the fancy Axis industries bracket would come with dowels but you would be wrong, it does however come with 3 mounting holes for the back side of the pump, I used all three of them.
Now the pump is supported via all six of its bolt holes, I better not have any problems with it, ever!
I also redesigned the oil filter mount, making room for the oem 1fz sensor. Since I am purplefj62 I did this one in purple just to give it some flare.
Now I just need to fine the correct tap for the oil pressure sensor. I was told that it was a M10x1.0 but this does not appear to be true. I believe it is in fact 1/8 BSPT as it is clearly tapered. According to my thread gauge it has 28 threads per inch. I will save that for another day.
Hoping to post a video of it running very soon, stay tuned!
