Well again I have run across a delema. And I think I must have pissed off someone somewhere because someone broke into my house today while we were out having dinner and ran off with all my good tools. Anything that was in my snap-on box is gone and this includes my 3/4in drive tourqe wrench that goes up high enough to tourqe the flywheel down on the 7.

Now all I have left is my 1/2in drive one that goes to a meesly 150lbs. Great right. Well I have to get thi thing together, and I dont have the time or extra cash laying around to spring for a bigger wrench....so my question today is....

Can I use the same method we use at work to tighten the flywheel bolt. Which happens to be, tighten the specific bolt to a set tourqe(150lbs in my case) and then using the "turn three faces of the nut after set tourq egauls 350ft lbs", this is how all of the mains are bloted down in CATs and Detroits. Could I use this method and has anyone else done it. It seems sound enough just wanted some input.

the actual torque you will get with 3 faces of the nut depends on the thread pitch and stuff, like how much the nut is going to actualy move on the stud would be different

hit it with a good impact gun, even some cheaper ones can put out ~400 ft/lbs of torque

Yes that is what I was thinking about. This is kinda dragging me down, first the ******** **** up my e-shaft threads then they run off with my tools. I am never going to get this thing together.

If I had some one that had a motor apart torqe there flywheel down to 150lbs mark one of the faces than finish tourqing it down then tell me how many faces it went past that, that would give me the correst number of faces I need to turn after 150

Like I said they ran off with my box, and it had pretty much all my tools (including all my air tools), only things I have left are the ones I keep in the truck, and its all just hand tools.

dude that sucks so much. Sorry i dont have any advice i know some people just take an impact gun and blast it on but i wouldnt recommend doing that. Hey man good luck getting your stuff make and if you find the guy who stole it we will all line up and kick him in the nuts for you or at least i will.

Carzy Driver

take the motor to a tire or truck repair shop and have them do it, shouldn't cost a thing.

fcdrifter13

Oh if I find out which idiot on this raod took it they wont have o worry about locking him up, or finding his body, or the bodies of his next of kin, or the .50 AE rounds used to split open there heads, no they wont have to worry.

Carzy Driver

cool, the desert eagle may see some action! do you have any spent casings I can have?

fcdrifter13

No I try to find all mine and reuse them, ammo = alot. I pick them up give them to my nieghbor and he does W/E you gotta do to make them usable again. Im still a n00b sorry.

run an extension and put the tq wrench onto the extension thing, look at the FSM

fcdrifter13

Dosnt that decrase the amount of tourqe i am putting to the bolt.

increase

your tq wrench goes to 150

you set it at 145, and with that extension, doubled the length of the fulcrum.

290, right where its suppose to be

fcdrifter13

Hmm good deal i guess ill do it tomorrow.

make sure you are using something that lengthens it to 2 feet, like the one on the FSM.... not a socket extension. :P

also, make sure the bar is straight....

fcdrifter13

Ok will do. Any tips for keeping the flywheel from turning at all. THe motor is out of the car and on the ground.

something long and flat that you can jam against one of the dowels and the counterweight
or a flywheel stopper that u bolt on and holds against the teeth

fcdrifter13

Yeah i had one of those, reffer to the top. Ill get it on somehow, and maybe have this thing running by the end of the week.

SureShot

I thought I read somewhere 150 ft-lbs plus 60 degrees (one flat).

I put a 4' pipe on my wrench handle & pulled about 100 lbs on the end.

You can always use a 1/2" flex handle and a bathroom scale. Mark a point on the flex 15" (1.25 feet) from the center of the socket drive. Put a small block of wood on the scale, put it directly under the mark on the flex handle, and pull up on the sides of the scale until you read 240 lbs.

1.25 feet x 240 lbs = 300 ft lbs

fcdrifter13

Yes I have heard this somewhere also.

HAILERS

Do what Slipin said. It's just what it seems. If you weight 150lbs and have a two foot long breaker bar and you stand on it, you have applied 300 ft/lbs to the nut.

You don't weight 150 lbs so compensate for your weight.

I don't have a high torque wrench and do this method and have no problems with it. Be sure to use the locktite on the nut.

rotorforce

You said they damaged the threads on the eshaft? Can you still get the nut on there?

fcdrifter13

Yeah i fixed that the other day, filed a lil and boom it went on.

ok so what I did, which is what they say to do in one of the rebuild videos is this...

I torqued it to like 150 then I took and made a mark on one point of the nut and a mark on the flywheel surface at that point, and then tightend it 1 more point clockwise to get that extra umph...

This almost tipped my engine over... I was like... DAMN!!!
