There are a lot of try and error to find right solution. It's frustrating, but also the feeling of archiving goal is priceless.

I almost finish rebuilding transmission gear and here is my story of rebuilding tranny.

 

1st try and error

Don't put the idler shaft onto the plate before finishing push in mainshaft and counter shaft.

You cannot put counter shaft into center position of the shop press to push in.

2nd try and error

You cannot put the snap ring if the direction of syncro for 3rd and 4th gear reverse. There is abig washer and no space to put snap ring if the direction of syncro is wrong.

3rd try and error

You need to put the short mainshaft of main drive before you push counter gear together onto the plate. You cannot put the short mainshaft later.

Tips:

It's easier to push in bearing onto the counter gear before push into the plate.

 

Tips:

Use grease to hold the small ball.

 

Tips:

It is easier to rebuild tranny using wire to tide up counter shaft and mainshaft before push in the plate.

 

4th try and error

Don't use gardening wire. It's not strong enough. That's for tomato, not for heavy metal. I end up go to HomeDepot to purchase 16g wire.

Tips:

Use some bar to hold the washer when push in the mainsahft to the plate. This way, you can avoid dropping the small ball.

5th try and error

mainshaft nut for FS5W71B (wide ratio / from call 280z tranny) is 32354-E9802(or 32354-E9804) right hand thread.

mainshaft nut for FS5W71B (close ratio / from 280zx tranny) is 32354-E9803 left hand thread.

I have now 2 left hand thread mainshaft nuts now.

Thanks Leon. You made great progress!

How's your prep for wedding goes beside engine build?

 

I started writing up what I have done during summer.

 

spitz17,

I watched youtube video so many times before hammering on actual body.

I was so scare before actually hitting body.

 

 

 

If you don't hitting too much with strength, the metal is not much stretched, I think.

Off course, I need to put a little bondo to final smoothing body.

 

I thought I have just 2 minor dents on my car.

I was planning to paint entire car, so, I started stripping paint with paint stripper...

This was just beginning of horror story...

In order to prep paint, I decided to test mount Type1 fender from MSA.

Oh, no, I'm surprise the poor quality of this fender.

Left and right side are not balanced especially signal mount area...

Almost straight mount with side line. In order to do so, I need drill hole onto headlight buckets.

Working on body paint removal.

I use Aircraft paint remover that a lot of folks recommended.

Using blade to strip down paint. It was difficult to remove paint because the paint remover dry out so quick before the paint get soften, but when I put more paint remover, it get easier.

Hi Perfect240z,

 

I use POR15 Metal clean to neutralize rust and primed canned spray for temporary purpose. I will spray Epoxy Primer later :-)

I decided to use Fiberglass Hood instead today.

I got this hood from Craigslist during Summer, but it has 2 rectangle holes.

 

post-25175-0-09239000-1381207069_thumb.jpg

 

I use fiberglass repair kit to fill the holes.

Try to grind down extra fiberglass create air pollution in my garage!! What a mess!

I decided to continue work on the hood at backyard....

Went to junk yard to hunt donor car.

But I need to drop down gas tank in order to remove bumper bracket and cut inner panel....

Also, running out of battery of the saw and blade.

 

Day 2 at junk yard.

 

Use engine lift to bring up rear end of the body.

Back home and start clean up the panel I got.

I try to be extra careful not to cut too much. Spot welding section is hard to trim down.

post-25175-0-15666000-1381874217_thumb.jpg

 

Oh, I used up a lot of grinder...

post-25175-0-09493300-1381874232_thumb.jpg

Remove old paint and did rust treatment and primed it.
