The Stovebolt Site Forums The Shop Area General Truck Talk 3600 running board bracket replacement

Recently purchased a 3600 frame. Two of the running board brackets are shot driver/passenger side middle bracket. The guy who sold it two me says he has a bunch laying around in good shape. Is there a difference in drivers side a passenger side? I just don't want to install the wrong ones.

Also, I'm planning on bolting the replacements in instead of the factory rivets. Unless there are any other suggestions.

Thanks

They should be side specific, accounting for the taper of the frame from front to rear. At least they are on a 3100.

Yep, FAM indicates left and right for all models for the front brackets, a single PN for center brackets, and left and right for MOST 3600 models for rear brackets.

Sounds like aftermarket is probably the way to go then unless I can literally take them off the frame myself. Thanks for the help

My running board brackets are bolted on. Problem I had was I waited too long to bolt them on. The front ones were the problem - it would have been a lot easier to bolt them on before the brake booster and battery tray were installed. The center ones were OK.

So is there a difference between 3/4 and 1/2 ton with these? I'm finding aftermarket one but with no info on weather they fit both 1/2 and 3/4

What year 3600?

It's a 47-54 3600 frame.

To narrow it down it has shackle style rear cab mounts which I believe makes it somewhere between 47-51

Section 7.016

Left and right are different on front hangers.
The other hangers are same on left/right.

The rear hangers for 3100 vs larger trucks look to be different?

Wait too see what other members see/interpret from that info in that MPB.

Looks like the center and rear are the same. Makes sense since the 3600 and 3800 frames straighten out vs. continually angled like the 3100.

Just a clarification on cab mounts, 1947 until very early ‘49 used a center pivot with rear bumpers. The mid-49 thru 55 1st series use the shackles.

That's perfect then. This guy says he has a bunch and confirmed they were off of a 3/4 and has a frame stripped for me to compare them to. Thank you guys for your help.

There is a right & left on the front & rear running board brackets as they have a slight angle to them.

The front brackets point towards the front & the rear brackets point towards the rear.

The center brackets have no angle to them & they are the same for both sides.


It is sometimes difficult to properly I.D. the brackets as they are prone to being twisted & bent on trucks that have been wrecked.

Is this true for both 1/2 and 3/4 ton?

Per my parts books...

7.016 Step Hanger

Front Left 47-54 1/2 thru 2 ton...3683573.

Front Right 47-54 1/2 thru 2 ton...3683574

Center 47-54 1/2 thru 1 ton...3683634...(same part as the Rear below)

Rear 47-54 3/4 thru 2 ton...3683634...(same part as the Center above)

Rear 47-54 1/2 ton ONLY...3684103

There is no mention of Left or Right for the Center and Rear Hangers.

Thanks, MIke

Same codes as shown in the Master Parts Book that I linked-to, above.

FAM section 2 Sheet 7.00 shows the same numbers for 3100 thru 6500 series front hangers as Mike posted.
Section 2 Sheet 7.01 shows center hangers as the same number right and left for 3100 thru 3800 series.
Section 2 Sheet 7.02 shows rear hangers - different PN for 3100 (same one for L&R), but the same as the center hanger for on sheet 7.01 for 3600 thru 4100. Sheet 7.03 shows that same PN (3683634) for 4112 models and 4400 thru 6500 series.

So other than front brackets, center and rear hangers on a 3600 would be identical. Pretty good chance of getting the correct one.

Awesome. Thanks for the help guys

Here's an update for anyone else who was interested. It was fairly easy to get off the old brackets. I ground down the backside of the river until I was flush with the frame, then used a cold chisel to remove the rest of the rivet.
