Another squeeze, just to the limit of pinching.
bkrantz
Sep 16 2020, 07:48 PM
With the pressure released, the bushing rebounded a bit.
bkrantz
Sep 16 2020, 07:49 PM
I then pressed into a 27mm socket, matching the outer rim of the eye bolt.
bkrantz
Sep 16 2020, 07:50 PM
That was enough to get just a bit of the bushing edge out the other side of the eye bolt.
bkrantz
Sep 16 2020, 07:51 PM
I then used my blunt ex-screw driver pry tool to ease the edge out all around.
bkrantz
Sep 16 2020, 07:51 PM
Done.
bkrantz
Sep 16 2020, 07:52 PM
Then I pressed in the metal center bushing. Again, lots of soap.
bkrantz
Sep 16 2020, 07:53 PM
And then a smaller socket to press against the rubber bushing.
bkrantz
Sep 16 2020, 07:54 PM
Centered.
bkrantz
Sep 16 2020, 07:57 PM
Ready for the final assembly. The specs come from the factory shop manual, and specify the lateral dimensions (278 mm left and right from center) and the angle of the eye bolts (9 degrees down to the rear).
bkrantz
Sep 16 2020, 07:58 PM
I then put on the bellows (small end to the inside).
bkrantz
Sep 16 2020, 07:59 PM
And the eye bolts with the stop plates.
bkrantz
Sep 16 2020, 08:00 PM
To get the rack to sit properly horizontal, I made a pair of stands that screw into the rack mounting holes.
bkrantz
Sep 16 2020, 08:01 PM
With a little adjustment, the rack now sits horizontal.
bkrantz
Sep 16 2020, 08:03 PM
To measure the angles of the eye bolts, I grabbed some long bolts, and some tape to shim these for a snug fit.
bkrantz
Sep 16 2020, 08:04 PM
Here's a top view, with the bolts propped up on some 2x4 blocks.
bkrantz
Sep 16 2020, 08:05 PM
Lucky 2x4 thickness! The angle is right on 9 degrees.
bkrantz
Sep 16 2020, 08:09 PM
Next is to measure the lateral dimension, with the rack itself centered. The spec is 278 mm. Note that the adjustment is a bit crude, since the eyebolt has to screw in or out a complete revolution to maintain the proper angles, both down to the rear and turned out to the front (as seen from above).
bkrantz
Sep 16 2020, 08:11 PM
I set both sides. Interesting that the left side was screwed in fully, while the right side was out one full turn.
bkrantz
Sep 16 2020, 08:12 PM
I snugged up the lock rings, but will check dimensions one more time tomorrow before final tightening.
bkrantz
Sep 17 2020, 06:45 PM
Final bits today for the steering rack. I did double check dimensions and angles, and then tightened the lock rings. Got this tool for the job.
bkrantz
Sep 17 2020, 06:47 PM
Here's all the parts gathered for installing the lower steering shaft. That includes a new rubber coupler and lock plates.
bkrantz
Sep 17 2020, 06:48 PM
The coupler first mounts to the lower shaft.
bkrantz
Sep 17 2020, 06:49 PM
After torquing to proper spec, the ends of the lock plate fix the bolt heads.
bkrantz
Sep 17 2020, 06:51 PM
And then the coupler bolts onto the rack input yoke.
bkrantz
Sep 17 2020, 06:51 PM
Lock these bolts in place, too.
bkrantz
Sep 17 2020, 06:53 PM
Then comes the plastic cover and the lower shaft bearing. Ready for installation.
bkrantz
Sep 18 2020, 07:40 PM
Just some minor progress today. I took another batch of parts out of the Evapo-rust bucket, including the frame for the parking brake switch. Here it is reassembled.
bkrantz
Sep 18 2020, 07:42 PM
Also from the bucket, the transaxle mount pieces.
bkrantz
Sep 18 2020, 07:44 PM
And starting on the parking brake lever. A bit ugly.
bkrantz
Sep 19 2020, 07:18 PM
A bit of garage cooking, to warm up the plastic grip.
bkrantz
Sep 19 2020, 07:19 PM
Grip removed, and a bit more cleanup.
bkrantz
Sep 19 2020, 07:24 PM
Primed and painted.

Much better looking there Bob. Nice

Now for the big job of the day: installing the rubber bushings on the front A-arms.
I decided to try some different methods. First, I did not heat the bushings or other parts. Second, I put my new taller press to use. I had the same Dake press in a bench top model but could not fit the A-arms (or some other things). My son has been wishing for a press, so his birthday will come early.
bkrantz
Sep 19 2020, 07:34 PM
Here's my process.
1. Press the bushing into the rear housing. Lots of liquid soap.
bkrantz
Sep 19 2020, 07:36 PM
2. Bushing pressed in.
bkrantz
Sep 19 2020, 07:37 PM
Here's the 914 Rubber inner guide, to ease the bushing onto the A-arm. The tape makes for a snug fit to center the guide.
bkrantz
Sep 19 2020, 07:38 PM
The guide in place.
bkrantz
Sep 19 2020, 07:40 PM
3. Starting to press the bushing on, over the guide. The stack include the other 915 Rubber guide, with the recessed end inserted into the housing. Lots more soap.
bkrantz
Sep 19 2020, 07:43 PM
Pressed all the way on. With the pressure released, the bushing rebounded a bit.
bkrantz
Sep 19 2020, 07:46 PM
So I reversed the guide and pressed again against the housing. I also left the pressure on for a few minutes to allow the rubber bushing to creep into place.
bkrantz
Sep 19 2020, 07:48 PM
4. Once installed, the bushing and housing must be adjusted to the proper angle to ease A-arm installation.
First, set the arm horizontal (and right side up).
bkrantz
Sep 19 2020, 07:50 PM
Then, check the angle of the housing. It should be 14 degrees from vertical, rotated "up". First check shows only 10.
bkrantz
Sep 19 2020, 07:51 PM
A bit of twisting.
bkrantz
Sep 19 2020, 07:51 PM
Now 14 degrees.
bkrantz
Sep 19 2020, 07:54 PM
5. Install the rubber bushings into the front A-arm body mounts. Note that the mounts have a top and bottom, with the raised bosses on the top.
bkrantz
Sep 19 2020, 07:56 PM
Like the rears, lots of soap, and press the rubber bushings into the mounts.
bkrantz
Sep 19 2020, 07:56 PM
Ready for the A-arms.
bkrantz
Sep 19 2020, 07:59 PM
6. Pressed into place.
