Well, lost about 40lbs today.
While the weight reduction is nice, my main reason is to clear the way for my divorced j-pipe. It also gives me lots of extra room in the engine bay. The pro’s simply outweigh the con’s.
I picked up a new alternator belt from NAPA. It’s made for a B13 Sentra SER without A/C.
It’s only four rib, but that’s fine for this application.
All was going smoothly until SNAP…
I broke the alternator adjustment screw. It must have somehow been weakened already because I wasn’t forcing it when it broke. It wasn’t really even tight yet. At least it didn't break off inside the adjustment block.
I spent about an hour on the phone calling various places around town, but there’s just nobody that stocks M8x1.25x150mm screws. I even checked the FSM to see if GA’s used the same bolt (I figured I could find a GA Sentra in a junkyard). I finally gave up and called my guy at the local Nissan stealership… Friday at the soonest, probably Monday.
Sooo I decided to focus my energy on something else. With the A/C condenser out of the way, I wanted to push mount my fans. I already have some nice FAL fans.
According to my research, the process was pretty simple. They could be push mounted by reversing the blades and reversing the positive and negative wires. The rest I figured out along the way. I’m not sure how other fans are set up, but this might help somebody out.
Here’s the underside of the fan.
They were nice enough to label the blades:
The blades are held in place with this clip:
It was pretty easy to remove. I just pried up with a screw driver and pulled the other end with pliers.
Here’s the post that the blades mount on with the clip removed. Note the little indentions in the brass piece surrounding it.
At this point I expected the blades to pop right off, but not so fast. It was going to take a good tug to get the blades off and I didn’t want to break the blades. I decided the best course of action would be to loosen the motor from the front of the fan and force the post through using a hammer and a punch.
The motor is held in place with three screws that require Torx bits. An allen wrench did the trick.
Once those screw were removed, the only thing hold the motor in place were the blades on the other side. I propped the fan between two boxes and put a towel underneath to catch the motor when it falls.
A few good whacks with a center punch and it came apart nicely. Here is the post without the blades:
The indentions in the brass piece on the blades lock into this pin. I flipped the blades over and reassembled everything.
I used some crimp connectors, shrink tube, and electrical tape to rewire the connectors. Then I mounted them up.
Since I don’t have an alternator at the moment, I couldn’t test them out, but I’ll do that before I drive around with them. I’m sure everything will be fine.
Anyhow, I'm back at it. Look for the divorced j-pipe to finally be installed very soon. I've also got some more really cool parts just sitting in the garage at the moment, so there's more good stuff to follow.
... when you flip the blades they end up facing the same way. Maybe there is something about the angle or curvature of the blade that it should be flipped. Anyhow I'll make sure I'm good.
