Help Need - Front Axle Keeper Washers

[Dirk Leegwater (RIP)]

Hi Phil,

Here a pic of a "Front Hub Retaining Nut Lock" washer.
Part no. GM-1810181 / C118Q-1192

Mvg. Dirk

Looks stange Dirk.......

Is it one washer or two....? looks very specialized to CMP only...!!

Or is the washer made of two parts and each half can be hammered back on the nut on each side.....?

Bet you Phil will order a bunch....

We made them in the lathe from hollow bar, simple cut to form two sides, dob of weld then file the tang square.

Hi All

Thanks to all who have responded so far, I was wondering if Dirk might have them, but the problem was trying to address is finding a modern application for these that might be more readily available to all of us. These are an expendable item which (I have learned should be replaced every time the axle nuts are removed)

I'm working on a longer better write up of this experience which I'll try to post soon.

From the picture below you will see the right and left keepers both of them sheared off. Yes I made these up out of sheet metal. I spent yesterday trying to make replacements out of 13 gauge steel using the lathe and plasma cutter. So far I have not been able to produce a replacement that I will trust.

Total cost so far for all new seals bearings and races/cups is $325 US all the Timken part numbers are still good.

Cheers

I've been searching the web for a dimensional listing which would be a match and while I can find the rear ones I have not found a source for the front. The problem being the diameter of the threads and the key way or tooth size.

In checking out the sources people have e-mailed me I am discovering some interesting things such as one major US sellers of old Ford parts uses the same catalog as one of the Canadian sellers with different headers and footers on the catalog page.

My next step is to check my other trucks to see if I need to be replacing the keepers on them as well and to confirm what sizes my trucks have. Once I've done that I maybe contacting Dirk and asking him to post me a bunch.

Please keep pondering on this while your at it check your own trucks, also think about the logic of why both would fail and why the left side nuts backed themselves off.

Cheers Phil

Hi Phil, as for the left side nuts coming loose on the wheel bearing the forward rotation of the wheel will tend to loosen the nuts. On the right hand side the rotation would tighten the nuts. That was the reasoning behind the left hand thread wheel nuts on the left side of CMP vehicles.
As for the tang shearing off the washer I have had the same problems when tightening the outside nut. Over tightening the outside nut tends to turn the inside nut slightly and shears off the tang.
I have no idea on where to source the washer. Any medium duty trucks that I have worked on have a flat on the spindle for the washer and not a tang. I will keep a look out on some of the industrial stuff at work for a washer.

The washer shown must have been off heaps of times as you only fold the tab over onto one flat each time, if you adjust the brg properly it will take years until it has to be redone, use loctite wickin 290 after final adjustment or threadlock when happy with result.

Hi Phil,
Just do a search for tab washers on the web. Stacks of manufacturers your side of the swamp.

Here's another picture of the ones Dirk has in stock, in comparison to what I took off my F15A. As you can see the tabs break after bending more than once.

The new replacement is slightly larger in diameter, and about twice as thick. I have yet to see how they work and if the increased thickness does not pose any problems. Will let you know later if there is anything to report.

And thanks for the heads- and write-up, Phil!

Hi Guys

Been meaning to post a follow-up I have several of the new design nut keepers thanks to Dirk via Bob. These are well traveled parts. I have not yet tried one of them but I suspect that they are a late replacement part which was improved, probably as a result of failures. The important part is that the tab is probably 3 times as thick as the original. Which says to me that field failures of the tabs was a significant problem.

I will do a close dimensional comparison and get back with what I find. The design of these look to be a far better design to copy. I'll be able to give a full life cycle test result ten years after I install one of them.

Thanks to everybody who gave assistance and suggested avenues of research.

Cheers Phil

Good to hear that you have the parts to get Beauty back safely together Phil. I revisted one of your old messages which had the link to when you took everything apart and you ended the message by writing More about refitting and reassembly to follow Just wondering if you did take the photos and if they have been posted somewhere yet? Merry Christmas.

Kind Regards
Lionel

Hi Lionel

Yes, I did take pictures of rest of the process of overhauling that entire knuckle and brake assembly, along with reassembly on to the truck. No I have not posted them yet, thanks for reminding me I will do it soon. Yes, truck is back on the road had it out for Veterans day nice 100+ mile trip.

Merry Christmas to all.

Hi Phil,

Did you end up fitting these "new design" lock washers? How they they work, do you have to bend them over the nut face?

Thanks,
Hanno

[Phil Waterman]

Hi Hanno

I actually don't remember if I installed one of the new ones or one of the ones I machined up? Or which truck as both of the Pat 13s have had the left front drum off since then. Will look in my special parts box and see if I used one or two. Strange I take pictures of so much but I don't have a final assembly photo.

Do know that I've added checking all four retainers on all three trucks as part of the spring servicing.

Which ever keeper used, sure that it has tab bent down to lock the nuts.

Will check and report back.

Cheers Phil
