There are three differentials used on the f-53 chassis. the smaller weight classes use the Dan 80. That DF has a rear aluminum cover plate and that is the bolt pattern needed for the plate.

The others (Heavier duty) do not have a DF cover on the back but the gears (slang term, "Pig") is placed into the DF housing from the front. That DF pattern is going to be different based on if it's US made or Foreign which uses metric bolts. There are two different heavier DF and I do not know enough about them.

Maybe one is foreign made and therefore use metric bolts and the other is US made and uses SAE bolts. They may be of different design and gear ratio's. Like I said I've worked on DF but am not a skilled technician as far as they are concerned. That's where a truck shop has it over my experience.

Here's my guess the lighter units 18,000 and 20,000 which probably also use the 19".5" rims and tires use the DANA 80. that's what we have. It's an 18,000 lb chassis 31' long with 19.5" tires.

When you get into the 34' to 36' and above while still into the gas units and F-53 chassis they use the larger DF because of the weight and the 22.5" rims/tires.

That may also be the 22,000 or 24,000 and into the 26,000 lb chassis. That's where the heavier duty DF are used. Maybe the US made is one gear ratio and the metric one is a different ratio. I just don't know that.

If you were going to try and make use of the spare DF cover for a TB you'd have to know why the metric is used over the US made one. What determines when one is used over the other? It is 22,000lb, or 24,000 or 26,000 lb chassis?? That's what is going to determine who needs the one plate over the other.

TeJay,
Looking at the Super Steer web site the TB one would purchase for a Ford F53 20K to 22K chassis, item: Rear Trac Bar - Part# SS401/SS500
rear axle on F53 with 20,000- 22,000 GVW (Dana 135-150 differential) and Kodiak Chassis up to 24,000 GVW .

Going by their install instructions the parts included are listed as: 2 TB plates, 1 metric, 1 standard, and fasteners for each to the DF.

When one was to purchase TB SKU: SS401 / SS500 and use the standard plate anyone with the 20k to 22k chassis *should* be able to use the metric plate.

I would call Super Steer asking if the intended plate will fit your rig.

Paste from SS instructions

IMPORTANT: Two different differential brackets are provided in this kit. One bracket has STANDARD holes, while the other has METRIC holes. They are identified by different part numbers. SS302-3 for STANDARD. SS302-4 for METRIC. You must determine your differential type to properly select the correct bracket for installation.
Note: Some OEM bolts will be metric. Be sure to check the size closely before installation. Metric bolts are larger and are also provided in the kit to be used with the metric bracket.

This is my final test fit. Plate was painted yesterday and ready for the last install today. I will post more pictures and what i had to do in the next few days on another thread.

I like shiny parts. Looks good Bruce.
I am all of a sudden feeling ignorant.
Did I read standard or metric holes? Do they make drill bits in metric sizes? Or, are you talking threads. I never heard of a metric drill bit. But, I'm not a mechanic either. I'm a retired equipment operator. Got some dirt to move, I can do it!!

Larry,

Yes they make metric bolts and drill bits to drill metric hole sizes. Here's an example of what I did with bolts and sizes.

A 1/2" hole is .500 thousands. A 12-mm bolt is .70 mm smaller than 1/2". The 12-mm is bolt is what is used to connect the SB to the link ends on the SWAY control system. No a 1/2" bolt just won't fit through the front end of the SB.

I did drill my front SB holes out because I wanted to use 1/2" bolts. The SB is a hardened piece of steel. I had to sharpen my cobalt drill bit several times to do it and I wouldn't do it again.

Bruce91,

No that plate won't fit my DF because I have the 18,000 lb chassis with the aluminum DF cover on the rear. It's a completely different differential housing. Take another look at my pics showing the DIY rear TB. Those pics are on the thread "Questions about the CHF."

The back of your DF is a solid housing with no access. All your gears and stuff come out through the front by taking all those bolts out, removing the axles and laying the PIG on a stand on a work bench.

The next time you're at an RV dealer try not to alert the sales HAWKS so they don't swoop down on you and just crawl under the smaller F-53 chassis (19.5" tires) and take a look. Seeing the real thing helps a lot.

Can't wait to see your finished TB. You will have to take it for a drive. It will make a noticeable difference in the semi push. And in general make the handling almost one handed.

Tejay--My 2001 F53 chassis is the 16,000# one and it has the DANA 80 rear axle with 5.38 gears and 19.5" wheels. I just had it rebuilt; new ring and pinion, new pinion bearings and new carrier bearings.

I just read a 2016 Ford publication with all that information.

16,000 - 18,000 DANA- 80 GR 4.88

20.500 - 22,000 DANA - S110 GR - 5.38

24,000 - 26,000 DANA - 170605 - GR 6.17

I'd guess that the S110 might be the SAE DF and the 170605 would be the metric. That's is just a guess.

I used a 5/8 drill bit for the 3 metric holes in the plate for the bolt to go thru the plate.

i measured the shoulder of the metric bolt (.545) and the 5/8 is .625. That would leave me with .08 oversize.

Getting the hole placement from the wood template to the steel plate it would be hard to get hole placement exact. The extra .08 clearance worked out perfect.

TeJay,
I knew you had the 18k chassis with the rear DF cover.

Looking again at the SS web site following the links using the 18K chassis they have no TB available for the 14k to 18k chassis. For the 24k to 26k chassis they list a different part # with no extra plate.

Looks like only SS TB for the 20k to 22k chassis has the extra plate for metric.

That video is from Hendersons. They mention torque values.
Hope it helps.

I definitely put Loctite on. (Torque specs pic attached).

Thanks for all the research, I would not have guessed the specs can vary so much.
Thanks for this info! I am looking into installing a SuperSteer SS401 on my 2017 Baystar 3113 so it looks like it would be exactly the same as yours (Metric, long bolts).

Was the installation difficult? Do you notice a big difference with the Rear Track Bar? I have done the CHF and have a Steering Stabilizer already so I am curious as to your opinion on if you noticed a big change?
