FRONT AXLE WEDGES

Post by sv4670 »

I understand there is a taper wedge fitted between the front axle and the springs of the vintage minor/ M type. This is to set the correct castor angle. My question is: is there a corresponding taper washer under the head of the bolts that clamp the axle to the front springs? If not the bolt head will be pulling down onto an inclined surface - unless the axle beam is machined with an inclined surface.
Thanks in anticipation.

No corresponding taper washer I'm afraid Derek. Not the best engineering job from Messrs. Morris and Kimber!

More importantly, make sure you fit the wedges the right way! Thick end to the rear.

Thank you for that. I shall have to make my own taper washers then - very bad practise to bolt down onto an inclined surface.

Well, I've never heard of anyone having bolts fail, so if they've been good enough to last 85 yrs on my car, I think I'll leave them be.........

The taper wedge angle is 3 degrees. I have made some taper washers to go under the head of the bolts but I am not sure it was worth the effort, anyway the bolts will be pulling down onto a flat surface. Not a brilliant photo but the washers are spot on. Ian Harris supplied the wedges.

Just a small point about these bolts. Like the U-bolts at the rear, these bolts were originally fitted with pairs of thin nuts to provide an element of locking.

I think Ian Harris does nuts & half nuts, if not sure Namrick do.
