Re: Restoring Rusty
For the side with the tank do the two outside and the top one then you should be able to rotate the hangar with some force and get the last one without removing the tank.
Just make 100% damn sure that your tank is covered up if you do ANY grinding lol. |

ok, so here is what the truck looks like lowered 2 inches in the front with one loop cut off the stock coil springs, and lowered 2 inches in the rear with aftermarket 2" drop shackles
there is a bit of a rake to it, with the rear being higher than the front, that's where the 2" drop hangers come in, stay tuned... |

updates, updates, updates...
the day started off with a field trip to Harbor Freight to buy some 6 Ton car jack stands, they happened to be on sale plus they let me use one of their 20% OFF coupons, so for $35 bucks out the door, you can't beat that and now we have some stands that actually reach the rear half of the frame |

first a special shout out to my buddy GTO Mike who came over and did half the work, thank you bud
the day consisted of pretty much a lot of drilling and grinding, as we tried to use both techniques to get the hangers off, I think drilling a 1/8th pilot hole all the way through the rivet helped punch it out, my buddy Mike believes grinding off all four heads off the rivets than hammering the bracket off first than tapping out the rivets is the key, just some ideas for you |

Mike worked on the driver side and I worked on the passenger side, the danger side by the tank, I made sure all vents were plugged and put a wet cloth towel on top of it to catch the sparks
I could only get to the first two on the gas tank side with the tank still attached |

we were making sparks all day long

Mike got the driver side off first, here are the two hangers side by side, we wire wheeled the area behind it and dabbed it with some left over POR15 to match the rest of the painted frame rail
this time of the year (late fall) this is gonna have to dry for a couple of days |
Re: Restoring Rusty
Whacking the hangar off before the rivets is the easiest and best way and what I did as well.
|
Re: Restoring Rusty

and so the gas tank had to come out on the passenger side to get to the other two rivets, just so you know it is impossible to get at them from the inside of the frame rail because they are tucked in between the cross member, which is also riveted in
do you all think I can clean this tank up with a wire wheel in order to paint it, or will I blow myself up? |
Re: Restoring Rusty

with the fuel tank out of the way we were able to grind down the other two rivets and get that hanger off too
|
Re: Restoring Rusty

after we cleaned this frame rail behind the hanger and where the fuel tank used to be, we went further and discovered this stamped number on the frame
12-12-73 Is that a born on date? Is Rusty's Birthday coming up? |

I swear these rivets look like bullet slugs, don't they?

and some parting shots of our Support Cast (get it support?) I recon bigger trucks maybe 3/4 ton or 1 ton use all six rivet holes on these brackets but my 1/2 ton only used the top four?
also I noticed is that they are switchable / interchangeable left to right, which is such a smart design, ie there is no left one and no right one |

If I am reading this Bolt Grade Table properly than LMC Truck has included some Grade 5 (3 notches) bolts with the hangers, and perhaps Grade 2 Nuts and Washers
The Greg is not a fan of using Grade 5 hardware for suspension componentry! http://www.rzrforums.net/attachment....2&d=1369585965 |
Re: Restoring Rusty
Grade 5 is perfectly fine but I would not use grade 2 at all.
I had to use a bunch of grade 5 on mine because trying to find a place open on the weekends that stock the appropriate quantities of grade 8 was impossible. If you can use grade 8 do so.. if all you can find is grade 5 it will be ok as long as EVERYTHING is grade 5. And yes you can wirewheel the tank if you want without blowing anything up. |
Re: Restoring Rusty
The important thing with a gas tank is that it should not be "empty". As long as a little bit of wet gasoline is present in the tank, the vapors in the tank will be too rich to allow an explosion.
I've actually watched a guy weld on a gas tank with gas in it. A bit unnerving, that. Another option is to empty the gas and fill it all the way with water to force the gas vapor out. You can then empty the water out. Any little bit of water left will be taken up by the alcohol in modern gasoline. The water thing was my preferred method when working on motorcycle tanks. I have wire-wheeled on a fuel tank with gas in it, though, repairing a crack in a gas tank on the car with -- you guessed it -- JB Weld. I needed to get a clean surface for the patch, so I wire-wheeled the area around the crack, which of course was open to the inside. Wet gas in the tank, though, so too rich for ignition. |

The big thing is torquing them to correct spec. Grade 5 3/8-16 is 30 ftlb. Grade 5 3/8-24 is 35 ftlb. The Grade 8 numbers are 45 and 50 ftlb. (Those are dry numbers. Do not lube the threads when you install them.) If you seriously under-torque or over-torque them, they will ultimately fail. |

after allowing 2 or 3 days for the POR15 to dry on the frame it was time to mount the new leaf spring hangers, they did come with hardware
|
Re: Restoring Rusty

here is the driver side all bolted up, I went 30 foot pounds on these grade 5 bolts
holding the nuts down inside the frame channel while you torque these down is a bit of a pain since there are rivets and the cross member bracket in the way |
Re: Restoring Rusty

then it was on to the passenger side
|
Re: Restoring Rusty
1 Attachment(s)
and then we ran into a snag, we are about an inch too far back, the rear axle needs to come an inch forward for the leaf spring holes to align with the holes in the hangers
jacking up the axle would bring one side within 1/2 and inch off but no where close to getting both bolts, one on each side in |

we tried all sorts of tricks, wood wedges, removing the leafs from the rear shackles, removing the shocks, nada

finally I popped out the drive shaft from the diff and was able to get the rear end mounted, minus the drive shaft of course
|
Re: Restoring Rusty
1 Attachment(s)
this is how much off we are
So what now? Do I need to get the drive shaft shortened? I thought this two piece shaft should have some wiggle room and be able to go in and out, I know it don't go in and out of the Muncie SM465 transmission so where does it telescope at? Or does it? |
Re: Restoring Rusty
What does the other end of the drive shaft look like? The part attaching to the rear end never does but the front side should.

Re: Restoring Rusty
What an ugly contraption! I'm not to familiar with how 2 piece shafts work :\
But I would think where you think should be movement it can move. It may just be stubborn. |
Re: Restoring Rusty
Put it down on the ground and check it again.
|
Re: Restoring Rusty
The paint may be keeping it from telescoping, or you may already be in all the way.
Lowering or raising a a vehicle often requires playing with driveshaft length, since the driveshaft often angles down to the diff. Raising the diff (lowering the vehicle) shortens the required driveshaft length. |

I will be pulling the driveshaft out and examining it closely off the truck, wish me luck. I think it should come apart with force, I don't think there is anything holding it preventing it from being pulled out all the way. |

CENTER SUPPORT BEARING 1. Remove dust shield. 2. Remove strap retaining rubber cushion from bearing support. 3. Pull support bracket from rubber cushion and pull cushion from bearing. 4. Pull bearing assembly from shaft. 5. Assemble bearing support as follows: a. Install inner deflector on propeller shaft, if removed, and prick punch deflector at two opposite points to make sure it is tight on shaft. b. Fill space between inner dust shield and bearing with lithium soap grease. c. Start bearing and slinger assembly straight on shaft journal. Support propeller shaft and, using suitable length of pipe over splined end of shaft, press bearing and inner slinger against shoulder on shaft. d. Install dust shield over shaft, small diameter first and press into position against outer slinger. e. Install rubber cushion onto bearing. f. Install bracket onto cushion. |
Re: Restoring Rusty
unscrew the grease seal off the end of yoke and then pull. lot easier to pull apart with front shaft and carrier bearing still mounted in truck.
|
Re: Restoring Rusty
Well that is interesting because from that picture there is no way that would move because it uses a roller bearing which looks like it would be a press fit onto the carrier bearing shaft.
