Lock Washers or no??

[LopezCarguy]

If a bolt gets a cotter pin is there ever a lock washer also...for instance the u-bolts on front spring perch...drilled for cotter pins but mine had lock washers...and nuts will not tighten down far enough to get cotter pins in...

Lock washers and a nut and a castle nut & cotter pin both captivate the nut so it won't back off. I suspect that at some point who ever worked on the front end had a lock nut but not a cotter pin. At least he had the sense to use one. You don't need both I tend to use what was originally intended for the item being worked on. Tim

There is no need for a washer behind a castellated nut. None were ever used as far as I am aware.

Something to think about ...............
Car manufactors, today, never use a lock washer on any thing !

the 4 large rear engine mount bolts require both a locknut and safety wire. See Restoration and Judging stds, engine section. While not cotter pins, Ford did think that using one form of locking fasteners did not always obviate the other.

yea they use alot of fine threads or triangular bolts. or speed nuts which are kinda springy in nature.

but also something to think about is how often does one drive down a dirt road thats all wash-boarded?

How would a judge see the four bolts that are safety wired under the flywheel?

Lock washer is useless on the original Ford nuts used for the front and rear spring.

They are very hard, a file hardly leaves a mark, so the lock washer can not do its job. The lock washer can not dig in and hold.

They also make use of Loctite. Loctite is actually more secure than a Lockwasher.

I use them sometimes with castle nuts to get the cotter key holes to line up. Flat washers also. But I don't put my cars up for judging.

not the ones under the flywheel. They are the 2 inside each motor mount that fasten the mounts to the flywheel housing .

Haven't you heard of the new Xray program that will be utilized on all Blue Ribbon cars judged, starting this summer?

Could not find any reference to the rear engine mount safety wire in the Judging Standards.
Need to know how the rear mount was wired.

I don't have a picture, but it would be a figure 8 with the wire going through the holes in such a way that if the bolt tried to unscrew it would pull the wire tighter.

Here are a few methods: Thanks to supplier of photo, and as Tom Says.

Just wondering Mr. Lopez, did you install the anti squeak shim at the top of the spring pack or the slippery shims between the leaves? Both are going to make the spring assy. thicker. Those items are not needed.

Do a google search - you will find some data that show lock washers actually make things easier to undo!!! ( and of course, perversley, some data that shows that they do work!)

When building racing motorcycles back in the 60's I used Loctite, nyloc nuts and wire. Often all three on the same fastener. Beats having a dangerous situation occur on the track.

They don't.

The book has Restoration Guidelines and also a standard in how they are to be judged.

If one thinks of the book as just a judging book they will lose out on how Ford did it during the day.

The bolts in question are for the flywheel cover, not the flywheel. So the wire will be visible to the person judging the undercarriage.
