Revival of the Chickenhawk...


Recommended Posts

 

First on the agenda was wiring the turn signal flasher, but we couldn't do that until we decided where to put it. We looked around for a mount for it to no avail, then we came up with a crafty idea. What if we took the guts out of a brand new flasher, and put them in the original flasher case?

And we did...

Now with the "new" flasher screwed into the stock spot, we could run the wires for it (sorry for the crap pic)...

Also finished up all the wiring for the turn signal switch and brake light switch...

That harness might look way too long, but it's actually just about right...

With the wiring harness completely finished, I decided to tackle something else that needed doing soon, swapping out the locks...

As for the locks, I mentioned previously they don't just fit right up due to a difference in the holes for the stock lock...

 

Stock hole...

 

20211127_115622.jpg.fd49fd01a5e24bab3b40608ed6ddc195.jpg

 

 

Square peg, meet round hole...

 

20211127_115632.jpg.6716d4f926d810cb4a10f3c8917ae87f.jpg

 

 

A little filing with a square file...

 

20211127_115706.jpg.66e4ecf3fa242d35484f20c2b1c3472b.jpg

 

 

And make the left side match the right side...

 

20211127_121835.jpg.9bf7c2fb1817d70e8f4075ab2d4f2a8d.jpg

 

 

Now she fits right in...

 

20211127_122308.jpg.92087a1e9d4a3a493efb10e8045a4b4d.jpg

 

 

For the trunk, it is a little trickier, since you also need to tweak the lever arm a bit...

 

20211127_123539.jpg.c5b8ef1816cbc1236f19b427588b3b28.jpg

 

 

Hole modded and trunk lock in...

 

20211127_123548.jpg.925ff613243ad46d23dda67e0dff97b5.jpg

 

 

And here's why you need to bend the arm, so it will contact the stock lever for opening the trunk...

 

20211127_123622.jpg.519f772bb57b3621756c48164934c508.jpg

 

 

Now twist the key, and...

While I was cussing and fussing with those, Tim made some nifty aluminium covers for the stock license plate light holes...

With the harness completed, we decided it was time to move on to brakes...

 

We got the left strut out of the car and disassembled to see what we can see. The stock 280Z rotors are 10.6" and solid, but I had a new pair of Infiniti M30 rotors which are 10.7" and vented. And fortunately, they bolt right onto the 280Z hub and have a more favorable offset to them. We tried one of the Brembo 4 piston calipers and it is tight. Very tight. Like, "it'll probably knock off the wheel weights" tight..  😁

 

20211201_184023.jpg.92b4962ab830ce0a4105f2ad5144f184.jpg

 

 

At this point, we think what we are going to pursue is using the 2 piston Brembos instead. It is still way more brake than the car needs, and also looks decently schmick...

 

20211201_191124.jpg.da67c98138a346927c13bf0c3128f9aa.jpg

 

 

We have a tentative plan in place for how to build the caliper brackets to make these work. We need to get some plate steel and get to work on that, hopefully Saturday.

 

We also ordered a new starter and thermostat which should be here today, and that should scoot things along under the hood. Then I think all that's left in the engine bay is an alternator belt and radiator hoses. 👍

Sssssssoooooooooo... I guess I need to go to Metal Supermarket tomorrow?

Speaking of those, they fit the hole well enough...

 

20211204_132946.jpg.a533d5b22b310456d1615a84048d89fd.jpg

 

 

And are fairly unobtrusive...

 

20211204_132941.jpg.caa9b109432fdfb711e6a9e7b70c2868.jpg

 

Will test fire it on Wednesday night to see if it actually does the trick. 😁

 

We futzed around with the brakes a bit also. These will be the beginning of our caliper adapter plates...

 

20211204_131139.jpg.214747beee1754099239b53036967308.jpg

 

 

As well we installed the new starter...

 

20211204_114504.jpg.be9436a6ea94980c4cedf85bf9e2c456.jpg

 

 

And a new thermostat and thermostat housing...

20211204_114518.jpg.ca5b65edd05e5652d67f9c8abd3957d7.jpg

 

 

The housing was a funny one. We had lost ours somewhere along the way, and I found this one for sale new. It is listed as fitting D21 pickup (fits either Z24 or KA24E), but it says it does not fit a Z20/Z22. We took a chance and bought one, and it fits perfectly. 👍

LOL,I made those as mounts for a huge-assed 4"x4" box steel bumper we were going to install on the back of a Bronco a few years ago.  I had seen one of them recently, but wasn't sure if we still had the other.  I am super chuffed that they were both still around and will be perfect for these caliper mounts.  We're also going to upcycle some scrap steel we cut out of the Dajiban for the rest of the mount, making this install (kinda) free (-ish, if you hold your tongue just right and squint).

On to more brake stuff...

 

Step 1, we made a thing...

 

20211208_175507.jpg.66b44127099d998cd6c59a0f9c23c5bc.jpg

 

 

We noticed that the back side of the caliper mounting face was even with the back side of spindle face. So, step 2....

 

20211208_181951.jpg.80db1c4d1f173d914fc0e8f73f476fb9.jpg

 

 

Step 3, Tim tacked the bracket onto the spindle...

 

20211208_182424.jpg.5791958b02d7070a1fd224170be062f5.jpg

 

 

Step 4, pop caliper and rotor off and fully seam weld both sides...

 

20211208_183609.jpg.3a6ff153925cbad9a48ecd6be34634fb.jpg

 

 

Step 5, profit...

 

20211208_190340.jpg.06a1c38045cb2cfc221fb497d635991e.jpg

 

 

Checking wheel clearance after that, there is plenty of space with a 5mm wheel spacer, but it's VERY tight with none. 

 

20211208_190938.jpg.0d88421b48c587027bc7dd0ba1413c04.jpg

 

 

Back side has heaps of space...

 

20211208_190953.jpg.d204e070c1f3ef756fc2d779466de3bd.jpg

 

 

Looking pretty sexy... 🔥

 

20211208_190910.jpg.f95393c9bc6a4563140aa93cb81d679c.jpg

 

 

We need to disassemble it most of the way because we need to make some very minor clearance notches on the inside of the caliper, and torque the rotor down properly. Should do that on Saturday, so once that is done we can check wheel clearance again to see if it's possible to get by with no wheel spacer. Once it has the all clear, we can bolt it onto the car and do it all over again for the other side.  👍

 

We did discuss the need/want for additional reinforcement of the caliper bracket, and will do that if Tim deems it needed/wanted.

The "Overkill Enthusiast" in me wants more reinforcement, but there is probably "Just Enough Kill" in there the way we have it.

As I recall from my days on the 1200 forum, this is the way they do it in OZ. And if it passes Rego there, after being signed off on by a certified engineer, I think it's good?

 

But I am also okay with adding more kill.  😋

We got the strut reassembled and mounted back on the car. Turns out since we are using a rotor 3mm wider than the caliper was designed for, it was rubbing the built-in pad retention clips. Once we trimmed those down, it was smooth as silk. 👍

 

All good now...

 

.20211211_134848.jpg.37416f3fce6e19f2a48d8b00cb3fb5a1.jpg

 

 

We got the other side strut disassembled and started on modifying it. Bracket under construction...

 

20211211_124101.jpg.376eba5713fe0db5fb6a11f53b88e61a.jpg

 

 

That done and Tim tacking it in place...

 

20211211_131148.jpg.2673a973895904ab0300e017ef3dd0e2.jpg

 

 

Rotor and caliper off for full seam weld...

 

20211211_132050.jpg.0449b2e2f545f4e20571898a894ed59b.jpg

 

 

While I was fussing with that stuff, Tim made a thing! I like it. Cleans up the look of the radiator area and hopefully keeps us from denting the fins (again)...

I wasn't quite happy with the way it turned out... so we did a little more to it.  You can see it on my instant grams, or wait for John to post a picture.

Got the other strut assembled and on the car. And cut out a lot of the lower half of the fender so that we can get max steering angle, even under compression. 

 

And for gits and shiggles, put the rear wheel on and made some clearance cuts on the rear to better suit the big assed tires we are using...

Some of Tim's pics...

 

We removed the coil spring and jacked the wheel up to about 3" higher than static ride height to make sure even in bump everything would clear. On the front side, we cut out quite a bit...

But as you can see, no rubbing at full lock in either direction...

Repurposed a spare 280Z door entry scuff plate as a stiffener, and put some foam padding underneath it to stop any rattles. 👍

I like it!  A no-scuff radiator cover 👍

 

AND..Datsun logo, too!

This is the stuff!

 

Can't wait to see it on the dirt.
