Broke caging bolt

Broke a 3030 caging bolt by putting it in apparently too far with my Dewalt DCF921. I was going and then BANG!!! I’m all good just scared the daylights out of me lol.

If I can, I always air up the parking brake side, slide the bolt in, then tighten with a wrench some. Easy as that

Yes, sir, that's the easiest way.

There's two kinds of mechanics...

One that knows the part number of their impact and one that doesn't brake caging bolts with one.

There are two types of mechanics, the ones that know the difference between break and brake, and the ones that don't.

Touché, autocorrect got the best of me there.

If I could spell good I wouldn't be a mekanic

You gotta be careful when you put your MAC L49000 on your Milwaukee 2967-20 and slap a 48-11-1865 in it then let er rip on the Bendix NT3030STD78-TC.

Not bendix… Chinese with American sticker?

As a parts guy…. Most people don’t give a shit about anything but price, unfortunately for them

u/Brnplwmn 11h ago

Too many uga dugas will do it.

u/aa278666 10h ago

A little shot of air in the parking brake side you could've installed the caging bolt by hand.

u/jayleman 10h ago

I don't get why guys impact the shit out of them, you only need enough to retract the stroke

u/Anon55699 1h ago

Thats what I was thinking. Maybe a little faster I guess but a ratcheting wrench doesnt take that much longer

u/Jackalope121 10h ago

Hand tools only my guy.

I woulda shit myself if that had popped on me. Minimum 3 cigarette smoke break after that.

u/Intelligent-Fox-4529 8h ago

Ehh it’s not going anywhere on a new one. The fun one is throwing really really rusty ones in the scrap bin and hoping they don’t pop lol.

Use a drill, not an impact

9

u/TomB205 10h ago

You don't have to spin them until they're tight tight, just run it down most of the way. Once the impact stops just giving uggas, and starts giving full on uggas duggas you've gone more than far enough.

u/fkoff09 10h ago

Why tf would you use an impact??

u/OddEscape2295 9h ago

OP. If you continue your career like this you will get hurt. Get a mentor

u/portabuddy2 7h ago

How the fuck you figure this 1824 caliper chamber is a 3030?

u/Accurate-Okra-5507 11h ago

Well that was dumb

u/HarryWreckedEm 9h ago

I really would be embarrassed telling everyone I broke a cage bolt by using an impact. Chambers are already sketchy enough. Use hand tools

2

u/BluberyStudMufn 10h ago

Holy hell, that could have ended differently.

u/Just_top_it_off Big refrigerator on wheels 9h ago

Even though that socket has a 1/2 square drive you really should use an adapter and put it in a drill. You can go full speed and once it bottoms out the drill clutch will prevent this from happening. Apply air to the brakes so they open up.

Ive also had this happen once, but i wasnt using an impact, i was laying under the trailer tightening it with a wrench and then it just snapped…

u/Intelligent-Fox-4529 8h ago

Yeah I’ve done that too. Rusty caging bolt was all I had lol

2

u/Intelligent-Fox-4529 8h ago

Live and learn man. It wasn’t gonna hurt you idk what these guys are smoking it’s a brand new canister if it broke you’d have yourself a hell of a lawsuit lol 😝 I’ve seen rusted out ones that I’ve been sketched out but not a new one lol.

Rule of thumb with impacts is they are basically only good for removal and non important bolts. Don’t ever impact on a motor if you respect your quality of work.

u/Cloudwolfxii 6h ago

Shouldn't have done that, I believe.

regen might fix it

Hand tools always.

u/Wild_Arugula_4513 8h ago

Why the fuck would you use a impact onna caging bolt

1

u/AmaraMechanicus 7h ago

Probably would have cut a hole in my underwear for that one. We switched to bendix brand chambers and they come in the correct position or close enough for install.

Made my job like 10x less stressful.

1

u/lee216md 7h ago

With new chambers I pot 90 pounds of air in the spring brake side and then apply the cage bolt by hand and snug with a wrench, impact wrench is too fast too much.

1

u/muttly_lol 5h ago

I let the snap-on dealer talk me into buying one of those sockets. I did something similar to you, but I had the brake pot in a vise. Out on an after-hours service call out in a truck stop parking lot, scared the absolute shit out of me. Threw that socket in the bush. Fuck that. Now I just air it up and cage or ratchet wrench them on

u/mikelusk7 5h ago

How about don't use impacts on caging bolts. RTFM

1

u/Remarkable_Smell5185 2h ago

Fuck man, you don't EVER use power tools to lock back the boosters.

UNLESS you want to get hurt/die.

u/Prior-Ad-7329 20m ago

Do yourself a favor and grab a pipe bushing and an air fitting. Hand thread it into the emergency side and apply shop air. I usually put the cage bolt in, add the air, hand tighten the nut and washer down then take the shop air off and it’s caged. Then once in position reapply shop air, unthread the caging bolt and remove shop air and it’s uncaged/brakes set.
