Driveline / tailshaft mod
« on: January 08, 2015, 10:18:12 AM »
hi bugas, i have not been on for a while cause been flat out but i did a tailshaft mod on my van last night and figured the info would be helpful for others so i got some photos, (i only thought half way though i should be taking photos)
putting a 350 chev in my van
tailshaft needed 5inchs cut off it.
after talking to some people about it
made the cut, cleaned up the spigot, push the yoke back in with a few mills to be able to move it.
put it in the van, using the dial indicator managed to get the shaft tru within 5 thou.
tack welded it in position. checked it. all good still
pulled it out of the van fully welded it, welding opposites to try to avoid shrinkage.
put it back in. oh no it 60 thou out!
stared at it for 10mins
then noted which way it had pulled.
took it out ground the weld down on the side it needed to be pulled just so i could use the shrinkage to pull it back in to balanced.
rewelded it, checked it and i got it so its balanced again. its not perfect all the way around but its balanced evenly.
wont be driving with it for a couple of weeks but ill let you all know how it goes once im back on the road with it.
it took about 2.5hrs. with what i know now it will be much quicker so not a big job.
happy to chat to anyone that will have a go at doing it yourself (saved me 350odd bucks!)
