Non plunging 930 rear drive project.

[fabr]

The original setup was the way you describe it 3 pivots on the vertical plain....
the flanged u-joint yokes are thicker/taller than the cv's are, thus the inward offset 1.7ish so to deal with that I drew up new outers to match that offset. The only difference from inside to outside is the height of the pivot bolts I make the outer bolts 1/2" taller to help combat it folding in on it's self at droop.. it's either that or cut the whole back end out and start clean. ( which i'd like to do. BUT $$ )

if it installs, exactly like its drawn i'll have 0.055" of plunge. Of course that's like spotting a unicorn ... "Without some shrooms"
 
I get what your saying its all just a guessing game right!!  .. it helps a lot on getting a close starting point though

You'll be fine since the splines will slip some and allow for any additional plunge due to any chassis flex.

Lost a few posts here guys.  Should be good now.  Carry on.

Jersdunz had on, don't know who else.

I did forget to mention that .. The bitch about having the verticals pivots off plane like i'm doing is the axle as it rotates down. gets closer to the arm causing a big clearance issue on the cv cup at the bottom of the cycle.. it hits the arm.. i'll only get 36 maybe 38 out of it..

i'm sorry I forget my manners all the pics from this build are on another forum.
Here is some stuff to look at. just so your familiar with the setup.

There is no moving the inner arm mounts with out some serious modification.

I keep trying to kill this thread... not sure why.
Here was a super fun ride I ran most of it with a flat tire and didn't notice..lol






I think some of my u-joint troubles are with that muffler you can see there heating up my driveline.. it'll get moved again.

I'm thinking the exhaust has zero to do with it.

oh come on now ,serious modification is what we do best here wheres you sense of adventure 
ok so what rpm range did you run at when you stayed in 2nd before the rpm and on the blaster 26's? what is the gear reduction in the rpm and tooth count on front and rear sprocket now? what hp and tq is your engine rated at and at what rpm? yes you have to answer this 

[dsrace]

you got lucky that front tire didn't come off the rim lol but had you gone faster the heat may have re inflated it  i am surprised it didn't steer funny that direction  but glad no accidents from it.

with u joints.....the best i ever used were rockford u joints. everything else wore waaay to fast or flat gave up. spicers were 2nd on the list. in the 1310 series ( 1/2ton) rockford makes a fun in the mud series with have the grease zert in the end cap rather than in the cross section which makes the joint stronger and easier to grease imo.

It was heating it up enough that it required time to handle it..
I figured that could have helped break down the needle grease.
Before that I was killing one on a seasonal basis..

[dsrace]

ya that would be hot, now how about the info and specs i requested

Just a curiosity question with the heat. Did the other side ever give you grief or only this side? (Or is there a second exhaust dump on the other side too?)

I already told you, you ocd sum bitch...lol

5.4:1
Counter is 18
Input on box is 17.

It was pretty random ..
The last 2 failed under the hot side, one had just a few hours on it..

[dsrace]

and i didn't right it down so don't remember lol

[fabr]

Just how fricken close was the exhaust to the u joint anyway?

[dsrace]

have you ever looked to see if your honda motor has the same spline as the box? i know several yamaha and honda sport bikes in the same cc share the same spline just offset the sprocket a little more.
