Winter projects

[AlbanyBrian]

1993 #135 in now off the road for the winter. The project list is:
+) F/R wheel bearing/hubs (completed, AC Delco golds used as replacements)
+) Pinion seal replacement
+) Steering column pivot pin replacement
So one project checked off the list and a couple more to go. Before removing the old bearing/hubs I measured deflection at the wheel rim lip. All 4 had noticeable deflections when off the ground and moved by hand. Ranged from 0.025? to 0.040?. One rear came apart when removed from the knuckle. Not sure all 4 are the originals, but now all are fresh.

I agree Mike--In fact, I think I would make this number 1 before I start into a list like that. While I have no list of car projects, I do have to do the annual maintenance on my 1950's Lionel trains layout over the winter. Skipped it last year so it is really needed now. About 600 wheels need cleaning and oiling, plus greasing of gears, wiping down all the track with automotive brake cleaner, the usual repairs to engines and accessories that are running sluggishly, etc. Keeps me off the streets but at least I don't have to do it in a cold garage. --Bob

Maybe this will be the year that I pull the Bose
head unit and send it to Dr Don to fix the CD player?
I've threatened to do this every Winter for the 15 years
I've owned the car! I normally listen to the AM news
station, so it really hasn't been a problem.....

Or buy a FM transmitter / BT transmitter

Seems #10 has a magical attraction to it as a similar item is on my list, too [emoji6]

However, as I had to replace all suspension bushings, rear wheel bearings, front tie rod ends, all ignition coils, front left Bose amp and battery this year and did the heater core end of '22 my ZR is looking forward to a relaxing winter with no projects.

It's nice when things just work, and I don't want to jeopardize this great feeling

I'll focus on the older Audi unicorn I acquired some months ago. This thing needs a lot of attention - and hard work - to become what it deserves to be. Drinks and cigars included

My projects for the '91 ZR-1:

1) replace the battery
2) drive the car
3) drive the car some more
4) drive the car even more
5) re-fill the gas tank, drive some more

My garage expansion is making progress so this will help facilitate having all the cars "jump in and go" ready so that any good morning I have the opportunity to drive I can just gooooo..

These aren't necessarily listed in order. :D

A few pictures from the pinion seal R&R.

Getting started, viewed form back:

Rear portion of exhaust removed, lots of grease from seepage:

Exhaust removed, driveshaft removed, pinion flange and seal removed (C-beam back in place while seal issue was resolved, see below):
https://www.zr1.net/forum/picture.php?albumid=539&pictureid=5193
New seal installed and mostly cleaned up:

Pinion flange holder and torque wrench in place ready to tighten pinion nut to spec:
https://www.zr1.net/forum/picture.php?albumid=539&pictureid=5195

One thing I found out with the 4:10 gears the pinion seal and pinion nut are not the same as with the original gear set. The set up in this car required the Dana 36 pinion seal and pinion nut. I do not know when this gear set was installed, probably 20+ years ago. But apparently the pinion used has a smaller OD pinion flange and a smaller nut compared to the original gear set. The pinion seal and nut I ordered for a 1993 Dana 44 were not correct, the nut was too larger and the opening in the seal for the pinion flange was too large. The seal I removed when I cross referenced the number on it turns out to be the seal for the Dana 36. The diff. is a Dana 44.

I torqued the pinion nut per the Dana 44 spec, I wonder if I should torque per the Dana 36 since nut is the smaller size of the 36? Any thoughts on this?

Fix leaky clutch. I'm hoping it's a loose fitting on my Ram hydraulic throw out, but that means pull the drive shaft, pull the C beam, drop the tranny, just to tighten a fitting.
U Joints on the drive shaft (while it's out).
U joints on the D side half shaft. Did the P side already.
My poor car has been sitting since MR9.

That is precisely why I have never been fond of trying a Ram clutch setup. One small leak and everything but the kitchen sink has to come out to address the assembly. When they work, they work great, but when they need attention, that is a job I do not envy if you have to do it on your back.

Update on steering column pivot pin replacement:
Here is the steering column lowered on to the seat cushion, both side covers removed, my pin puller set up. A thread rod, 8-32, with several washers and a 13mm crows foot line wrench to pull against.

I think the hardest part of this pivot pin replacement is the reinstallation of this dimmer switch slider/actuator and the side cover that goes over it. It takes some fiddling to get it back together. As you fiddle with it all of a sudden it pops back in place correctly. This is the slider that goes in behind the side cover.
https://www.zr1.net/forum/picture.php?albumid=539&pictureid=5211
New pin reinstalled before side cover is reinstalled.
https://www.zr1.net/forum/picture.php?albumid=539&pictureid=5210
The hard part done, side cover on. Actuator not seen as it is behind the side cover.
https://www.zr1.net/forum/picture.php?albumid=539&pictureid=5213
Outer cover reinstalled, column ready to be raised and support bolted back in place.
https://www.zr1.net/forum/picture.php?albumid=539&pictureid=5214
I purchased my pin from Marc Haibeck and he was helpful with tips for getting the side cover back on. I also found this video on YouTube, link below, that was helpful. It is a pivot pin replacement on a 3rd gen Camaro, and they also show the actuator and side cover details on a column on the bench. Help me get a feel where the parts go because it is not very easy to see with the column dropped down on the seat cushion in a C4 Corvette.
