Okay this is the car in all its glory ugly as heck, but hey its an auto-x car. (IMG:style_emoticons/default/new_shocked.gif) This one is from my first season of auto-x with this car.



Heres what it looks like today. Made it even uglier (IMG:style_emoticons/default/barf.gif)



Here is the goal, I can sketch ideas, but I can not draw at the level of others on this forum. Thank you 914 Visulizer. and my black pen. Now if I could find a good front view. And the flares are not on the car since I'm not using GT Flares.



But you get the general idea.

Okay well now lets continue down the long path of making the OBX a quality unit.

First issue is when they machined the spool they drilled the last set of holes for gear oil to get to the gears from the outside. Thats okay, but they did not go back in and even de-flash the holes. (IMG:style_emoticons/default/chair.gif)



As seen in the above, so you must take a die grinder or dremel with a diamond bit and debut and chafer the holes. Or mount it in a mill and counter sink the holes.

So they look like this, Ah much better now.



Next you need to clean up all the gears, the honda guys just let the diff do this, I chose to spend a lot of time with various grits of sand paper and a glass plate. I learned this in college from one of my room mates, he was a Clarinetist and made his own reeds. (IMG:style_emoticons/default/screwy.gif) Same technique works very well for polishing things to better than new. their are 20 tops and bottoms to do. Maybe I'm then (IMG:style_emoticons/default/screwy.gif) one.



Still have a long way to go. Rinse and Repeat 40 times. Once done, they will be all nice and shiny on each end. Next is debarring the gear teeth. Oh come on guys really, I have to knock edges off all the helical gears. (IMG:style_emoticons/default/headbang.gif)



My Sir Andy picture taking skills come into focus again.

I did not take a picture of this because I noticed it when I as assembling. There is a hardened Pin on the upper section of the spool that aligns with a notch in the lower section. I had to know a bur off the pin to get the unit to seat correctly. For good measure mic the pin and make sure the notch matches or is just a hair bigger.

Reassemble in reverse order.

Torque the new bolts down to 23 Foot Pounds. Remove them one at a time and add a dab of blue lock tight to the threads and put back in. The factory morons can really screw up a set of threads, so it is always good practice to chase them before you put the new bolts in. Be forewarned these guys are not much of a machinist or assemblers, you get what you pay for I am guessing.

But I feel much better now running this in my car.

This guy sells a kit if you want to use it, Kit, no affliation, just used his stuff. His writeup on how to repair these is excellent also.

One item off the todo list.

Would it be appropriate to just throw all the gears in a vibrator/tumbler with some abrasive media?

Is it critical the parts go back in original position?

I guess you could do that for demurring the gears, I don't have one, so..... And no the gears don't have to go in specific positions, I just like to do that, little OCD about that stuff. Tends to make things easier to assemble when I walk away from a project for a while.

If I was to do only two things to the OBX, it would be deburr the return holes at the bottom of the gears where they drilled from the other side. And changing the bolts and shim stacks. Oh three things, making sure the guide pin fits in the its receiver space on the other side, and oh......
