Default Fc brake hose length

My hoses on front were 24”, clerk at shop measured, and then boss told him “don’t measure, flatten it out next to a new one”, sure enough, 24” not 22”, they look smaller if you try to “trace” the curves. dot brake hose and no brand loyalty on my end, just make sure end threads and length are same, what they look like in the middle is irrelevant.

So back to “airbags”

-pulling my safe t plus off; called factory, torque on 1-1/8” bolts is 120-130ft lbs. and if I don’t mess with bracket u-bolts, I won’t have to re-center the unit. (FYI: u-bolt torque on them is 25ft lbs)

then loosened the tie rod castle nuts, man those tapers don’t want to let go. Used dead blow hammer on top of another. Tried a tie rod press, it broke. Tried air hammer, nothing.
-Guys; is it just going to come down to heat, brute force and ignorance?
-What’s the torque for re-installing the castle but after this mess is over?

Found a fun love note from bluebird in the panhard rod removal: bolt is blocked from removal by the frame of the bus. yep… see pics. That’s a fool proof way to know no one has replaced the bushings! I don’t know if I will tackle that this time.
-torque for re-installing that monster? How it felt coming off, 300ft lbs?

Thanks again everybody for help, even the mutual disdain for difficult things helps motivate. It’s 100 and humid again today

Update, tie rod assembly out of both sides, PB Blaster, and a 4lb sledge on upside down castle nuts level with the end of stud. 4 hits, came off without drama.

RIP Lil press tool.

Default I AM SLOW WHEN I’M HOME!!

Well, I’ve got all 4 airbags out.

Purchase of 2 wrenches and modification of a couple tools has happened..

Oem Airbag large nuts are nylock jam nuts, 3/4-16 and use a 1-1/16” wrench.
NEW REPLACEMENT jamb nuts (and regular thicker nuts) are still 3/4-16, but use a larger 1-1/8” wrench. Husky branded gear wrenches are about $27 each and worth every single solitary penny, bought larger sizes they live in the bus.

The bottom and top smaller studs use regular 1/2’-13 nuts, 3/4” wrench size.

I replaced all hardware, those original thin nylock nuts are a liability for rounding off and so on. Also added a washer under all top nuts, makes it easier to get a wrench on them overall, coupled with the new jamb nuts, it’s almost “easy” compared to removal.

The brass airlines are quite a bear to get started going back on, but had no fitment issues with the taller 8997 bag stud vs the OEM 8992.

One of the rears was previously replaced, it is positively dated from 2010, and looks perfect, the other 3 look terrible, actually crumbly terrible, these airbags are very long lived bits of kit, vulcanized rubber is amazing.

Have some concerns about the airbags rubbing on the trans cooler lines!!

Attached pics, the front right bag is rubbing on the cooler lines, *now*; does it look like its been rubbing long term, or maybe this is a symptom from my 3k mile drive home last trip with that particular airbag being blown, and only fully extended while highway cruising at high rpm, even then, after a while.

I purchased new hardware for these, $24 each bolt!! Grade 8, 1-1/8” bolt, 7” length. Looking into the panhard bar rebuild threads now, how high should this be on my priority list?

try one of those long handled screwdriver looking pry bars.

Big bolts can be found at McMaster Carr,Cat,and one other place that escapes me.
Machine shop supply,dang,i will find it.too little too late.

Now Bill says you can check with a bar/screw driver,i think not!!
Just think,your trying to shift the weight of the coach against the eight of the earth,with a bar.
In just perfect situations you may do it,best bet,if the bolts still in backwards,replace them,they are factory old.

Not quite sure I fully understand if the rubbing is with the new bag, or with the old, possibly torn bag.

Is there clearance from your newly installed bag to the lines now? They don't balloon much, so 1/2" clearance when aired up would be plenty for me. And maybe a few big zipties to hold the tranny lines away.

Old bag was rubbing minimally, even though it all looks crazy, its not deep. But its got a few patterns on the bag side and its something I want to bring attention to. Would hate anyone to lose a ZF transmission to fluid loss etc, because of a cheap airbag.


The ZF Trans lines are snug against case, and theyre huge, in a not huge space will double check their range.

The old bags are a good 1.5 inches larger in diameter than the new, because of wear and age, i suspect. Maybe the new ones will be a non issue, but the work involved to get to that bag in particular is enough to step back and try to do “everything”

Good advice, McMaster has same bolts for $27 as well. Checked my receipts, $27 was the price for bolt and new nylock nut, so I guess I’m ahead!

Have 2 competing fastener stores within a block of each other local, they keep each other in line
