Day 84 - 28 Chev Ute Restoration (24th December 2015)
Santa came a day early with a parcel or reconditioned steering box parts, enough for the 28 ute restoration and the Red Chev.
On the photo below you will see that the inner hole on the bush appears to be off center.........Correct............This is why a good friend of mine who did the work is pretty clever.
You can replace the bushes in the housing which eliminates a small amount of play, but the only way to fully fix the problem is to either fit new gears (not available and too expensive to have made) or reduce the center line distances between the worm and sector gear.
This is where my mate comes in with a mod that has done thousands of miles in his 28 Chev truck with no problems, and that's good enough for me.
The process involves a lot of machining and is as follows
1. After removing the 2 sector gear shaft bushes, the housing is bored out to take a larger diameter bush.
2. The new full length bush is machined to be a firm rotatable fit in the housing, slightly longer than the housing and has a hexagonal end to fit a custom made spanner.
3. The ID of the new bush is then bored off center to suit the sector shaft.
4. With all steering box parts assembled, the full length bush can be adjusted to bring the centers of both gears closer together to reduce the degree of play between the gears.
5. With the desired amount of play between the two gears set, a locking screw fitted to the housing is tightened
An added bonus of a full length bush is the load on the steering sector shaft is now spread over a larger area, complete with the necessary grease entry point an grease spreader grooves.
As part of the process the two sector gear shafts were center ground to remove any wear, and look brand new.
My mate also sent me a straight pitman arm, complete with a new tie rod ball that he made and fitted.
This replaces the pitman arm on the 28 ute, which like so many other parts on this poor thing was bent and "distressed"

Chev 4 Steering boxes develop wear and excessive play in the steering wheel. After making the two normal adjustments possible, any remaining movement is caused by either worn bushes or the sector and worm gears are worn.

Very happy to receive this "care" package of bits and pieces, and many thanks to my friend.

Day 83 - 28 Chev Ute Restoration (23rd December 2015)
Yes! I have been working on the resto, lots of little jobs that need to be done, but as they don't make very interesting reading I am holding back on a large posting till I can show more details and pictures.
Things like
- Bushes fitted to brake backing plates and diff housing for handbrake half shafts
- Rebuilding worn half shafts
- Sorting out best parts to use for brake cross bar mechanism.
- Cleaning up about 50 wheel studs to find 4 good sets, (24)
- Measuring up front brake drums to use best 2 out of 5.
- Assemble front hubs, bearings, wheel studs, brake drums
- Select best 5 steel wheels out of 9 available
These tasks will keep me busy over the next day or so, but once done, they are history.
Should have a detailed posting in the next few days.
Cheers

Wanted - A good pair of 28 Chev Disc Wheel rear brake drums
Hoping someone out there may have a set to swap or sell, as mine are a bit thin.
I have a rust free pair of 27 disc wheels that can be swapped, otherwise let me know what would be a fair trade?
Regards
Ray

Day 82 - 28 Chev Ute Restoration (16th December 2015)
Very hot today, too hot to do any serious work in the shed, so I set about sorting out the next batch of parts to be reconditioned.
Disc Wheels
4 months back I had 2 of average condition, and was desperate to find more for the resto. With a couple of purchases and a donation I now have enough to select 5 good ones for the resto. The process will be to find the best 5 that run true.
Cross brake shafts, rear axle hand brake shafts, rear hubs, brake drums front and rear. All received the molasses treatment a while back, and are awaiting the once over and a coat of paint.
The rear hubs that came with the ute were "flogged" out, but luckily amongst the spares that came with the ute was a serviceable set .
The rear drums are serviceable, but I will try and locate a set with more meat on them.

Day 81 - 28 Chev Ute Restoration (15th December 2015)
Over the last 2 nights the rear axle brake backing plates have been reassembled and fitted back on the axle housing with high tensile bolts.
Had to do some running repairs to my chassis trolley as with the rear axle fitted the chassis is rear heavy and lifts the front wheel of the timber brake enough for it to move, and living on a slope this could be nasty.
The trolley now has 4 wheel timber brakes, Fred Flintstone would be jealous.
