Re: Daverods project 66
 

Good find Mac.

Re: Daverods project 66
 

So does the engine sit off the the side too?:uhmk: I don't get it, the cross member they gave me that holds the carrier bearing is centered?

Re: Daverods project 66
 

:confused:

Re: Daverods project 66
 

Don't think it matters (to a point), being parallel is the prime directive.

Mac. :chevy:

Re: Daverods project 66
 

Now I'm really confussed. My diff. and rear drine line sits off to the passanger side, my carrier bearing is centered and my engine is centered? How is anything parallel?

Re: Daverods project 66
 

The carrier and engine are the majority - they win. :lol:

Seriously - how much are we talking about?

Re: Daverods project 66
 

About an 1". You can see in the picture how far. Maybe it does'nt matter. Just wanted to know for sure? I mean they make a big deal about setting the pinion to a degree or so then it does'nt matter if your drive line is sitting an 1"to the left? Why don't they just make it so it's centered?

Re: Daverods project 66
 

From what I can gather - unless you're drag racing - it doesn't. :smoke:

I'll keep searching......

Mac. :chevy:

Re: Daverods project 66
 

Another thing people don't realize is that the pinion center line in hardly ever on the center line of the frame. They, also are offset to the passenger side.

Re: Daverods project 66
 

It doesn't matter that the two U-joints are not on the same centerline from the front of the frame to the back (my engine is set right 2" and the pinion is 1-1/2" right.) It only matters that their individual centerlines are parallel..

Re: Daverods project 66
 

So you think its normal.:lol:It must be ok. Alright I believe you. Thanks. Still don't fully understand the individual centerline parallel part. But I can live with it. There's lots of stuff I don't understand yet life goes on. Thanks Mac I'll sleep better tonight.

Re: Daverods project 66
 

perhaps a few off those people are a little off centre too
ron

Re: Daverods project 66
 

I don't get it either - but this guy thinks it's common. I'd think the "U" joints would just beat the crap out of themselves, but I guess not - unless you're regularly going to be driving flat-out. There has to be a frame guy you can talk to - without getting sucked into a "Yeah, for $1500 I can fix that for you" scenario.

Mac. :lol:

Re: Daverods project 66
 

as long as the axis of your external components run parallel to one another within a few degrees you are fine. the centre line of the eng and tran should be parallel to the cetre line of the pinion shaft to within those 3 degrees. the centreline of the eng and trans may sit 5" higher than than the pinion centreline. If you projected those centrelins past one another those lines should run parallel to one another.
next; sya that your vehicle is north and south and eng is north. pinion shaft is 1 1/2" to the right or east. the eng and trans centreline is straight N & S as is the pinion centreline. project those centrelines and they are running parallel to one another 1 1/2" apart. a d/shaft with a working ujoint on either end compensates for all this as long as they (the front and rear centreline are within certain parameters; 0-3 degrees of one another)
ron

Re: Daverods project 66
 

I thought that was my line? I'm pissed I think my trans in my 64 went bad. I did alittle burn out now it makes a funny noise in 1st gear and in reverse. Sounds like the shift linkage was hitting the driveline but I looked and nothing is hitting it.

Re: Daverods project 66
 

Drained my transmission oil in the 64 found 3 parts of a hand grenade.:waah: I wonder if it's cheaper to pull it take it down and get it fixed or pull it and put in on from the junk yard. Guess I better go pull it out.;)Suck:lol: Think I should put in another 3 speed?

Re: Daverods project 66
 

im confused

Re: Daverods project 66
 

Ya eh, is he talking magnitic north or true north.:lol: I'm thinking as long as the axle is straight and the engine is straight the driveline makes up the slack. As long as the angle coming out of the axle and the transmission are out of phase and set to around 3 degrees past magnetic northeast.:lol:

Re: Daverods project 66
 

maybe that is why your having a problem
ron

Re: Daverods project 66
 

:smoke:Maybe thanks for trying to help though. I'm sure it's not my only problem.:canada: Born in Vernon BC. Only lived there a day though.

Re: Daverods project 66
 

If you plan to keep it, I would get it rebuilt. Getting one from the yard you do know what has been done to it. However if your long term plan is to replace it with something else, then go the cheapest route. Then again if it is really trashed then it may not be worth rebuilding.

Does this help? :lol:

Re: Daverods project 66
 

Kinda. I guess I'll find out tomorrow when I see what they want for one from the yard. I have 3 auto transmissions sitting in my garage. I might put one of those in. I was just thinking what would be the easiest. The ones from the yard are guaranteed.:lol:

Re: Daverods project 66
 

another thing about having one rebuild is that you can have them make it a little stronger
i agree with tiggamonster that you dont know wat a tranny from a junkyard been trough it might just be that the rebuild one on an exchange basis aspecially a 3 speed wont differ so mush with a yard one

Re: Daverods project 66
 

Yeah - bite the bullet and rebuilt the tranny with heavier stuff inside - then you can tromp on it without worrying.

On Ron's description - I kind of get it.

3 degrees maximum drive-line angle, I'm assuming - in any plane.

Tail shaft of transmission to pinion of rear end. Piece of string from centerline of each component - from one to the other: Maximum angle can't exceed 3 degrees.

These components must point directly (parallel) down the centerline of the vehicle however even if they're offset - if they don't, that will create a situation that increases possible vibration.

Mac. :mm:

Re: Daverods project 66
 

sorry, the driveshaft can run at a greater angle. the 0-3 degree variance is the alignment between the centreline of the engine and pinion or in other words the variance of the parallel lines
eg. look at the difference in d/shaft angle between a 4 x 4 and a 2 wheel dr. quite a difference. the alignment of the eng and pinion between both remain the same
