Hi. Just a question: I have removed the propeller shaft to change the centre bearing and support. In the shop manual it says that you should mount the front shft 67,5 degree to the rear shaft. But when I took the whole shaft out it was aligned straight. My english is bad, but I hope you are understanding what I'm saying. Look at the pictures:
67.5 (in North America they use a decimal point) is a lot. Just put the drive shaft back in the way it was installed. A right angle is 90 The half of that is 45 The half of 45 is 22.5 45 + 22.5 is 67.5:
Thank you for answer. I though it was strange to, but look at page 11, or 40-47 from the original shop manual: http://www.teambuick.com/reference/library/67_chassis/files/40-d.php Regards.
They are referring to the angle of the yoke and the drive shaft. Not that you have to bend the two-piece drive shaft to a 67 degrees angle :TU:
I've read the shop manual some times now, but the only way to get the Riviera front axle yoke 67.5 degrees of is when you mount the front and rear shaft together. The rear shaft slide in the front shaft like a slip yoke. On the drawing it looks like the center bearing and support is removed.
So, what you two are saying is that someone once upon a time has changed the phasing? And original from Buick it's only one way to put these to shafts together? Thanks,
Ok. Thank you. I'll try to separate them tomorrow, and take it from there, but I should try to make it 67.5 degree offset?
HOnestly, I never noticed there was an off set. I'll have to look at it close next time Im out in the shop.
Ok. I've separated it now, and the front shaft can fit any way I want it to the rear. However it is "missing" a "teeth" or spline but, the rear yoke has all the splines and teeth, so no matter which way I'll rotate the driveshafts it will fit.
