Can I prime/ paint it after? How expensive is this stuff?
When building a drive shaft what is a good percentage for compression and extension of the splines? Say you have 6" of total spline engagement in the shaft. At ride I would think you would want a min. of 50% engagement (in this case 3"). A previous shaft I built had 75% full engagement at ride height but that seems like a lot. I guess this question has a lot to do with your related suspension travel.
The movement of the pinion is going to take or give an identical amount of spline portion when cyling from full compression to full droop. If you leave it at 50% then at full droop you will have very little spline engagement. Check how much it moves under full compression and only make it so that at full compression it is fully engaged, then you leave yourself as much spline engagement as possible at full droop.
I've been dealing with this for the past week and that's what I ended up doing. Clear as Mud?
I don't know that this is right or wrong, I take the distance yoke to yoke of the truck (say 36"), then I take the slip of the driveshaft (say 6"), subtract 1" from the slip (so now 5"), divide that in 2 (2.5"), then I make the shaft compressed length the yoke length minus the previous number (36" - 2.5" for a compressed shaft length of 33.5"). There is no magic to that, just what I do.
So at ride height you would have the shaft compressed approximately 60%? This is more in the ball park of what I was thinking. Just take the total length of spline (6") then multiply by .60 = 3.6" and at ride height there should be 2.4" of exposed splines. So 40% for compression and 60% for extension.
I always try to have as much spline engagement as possible, so i"ll build the D-shaft to be almost fully compressed under full compression of the suspension. I do this for two main reason: 1) it's easy to shorten drive-shafts 2) full compression should be a constant and is easy to plan for.
For leaf springs I allow a little more room because of axle rap and you don't want the drive shaft getting into the transfer case.
That's what I said.
I talked to jay at bvd today and he said that they do what Karl said to measure spline engagement.
I did 65% compressed at ride height. So about 4" compressed out of 6" total. I will let you know if there are any problems in the future.
any shops in cs that carry cb radio stuff besides just radioshack? I need an antenna and mount, left mine at home
The bigger truck stops carry CB stuff sometimes.
walmart might have some of the stuff
I think freightliner on hwy 6 carries stuff too
