Hello all, Just chumming the water today. As I restore my original generator projects, I have had to make the simple fender-style washers that sandwich the rubber generator bushings. The washers I was to have had where lost over the years and replaced with incorrect ordinary fender washers. I spent a small amount of time trying to locate accurate replacements or thinking about modifying existing extra thick fender washers. I finally concluded that punching out accurate copies of these parts would be a wiser course to take. Here is my question, "Are there Forum members out there who would like me to punch out a few extra washers to purchase/barter for your needs? "
According to the CJ-2A Parts List on this site, a properly installed generator will require (2) A-1401 WASHER, flat, 21/64" I.D. and (2) A-1396 WASHER, flat, 33/64" I.D. washers. The picture below will give you a better visual on what I am talking about. The picture only shows 1/2 the required washers. It only shows the engine-mounted generator bracket assembly. What is not shown in the photograph is the opposite generator attaching point encompassed into the design of the passenger side motor mount.

Joel, I'm in for 1 set.
Were you aware that the small ID has a chamfered hole? I thought Ron F had these, but haven't checked into it. Sean

Bob:
Well, depends on who you ask I guess. Over on the "G", they say it's a "funnel" for guiding the bolt through the hole. It is a very close fit, so that's a valid reason. In my opinion, it's there to provide clearance to the radius between threaded stud & shoulder (same thing that they do on the front crankshaft thrust washer). I've been PMing w/Joel about it. He says his bolts don't have a radius. Mine certainly do (.030-.035"), and with that washer hole explicitly spec'd at 21/64", without the chamfer, it would not fit flush to the shoulder on my bolts.

Hi all,
These "simple washers" have become more than just stamping out a few pieces of steel. I have been PM'ing with Sean, talking with Ron on the G, and trying to be less confused on what the purpose(s) of the chamfer is about on the A-1401 washer. There now appears to be different designs for generator bolts, rubber bushings, and washer specs out there. To make washers to fit and work properly for you would be require me to make it a custom order for each generator you wanted to mount. I am hoping Sean will accept the challenge of starting a new research thread on these two washers, A-1401 and A-1396, with the idea to gather some solid evidence as to what is what. Personally, from this proposed thread, I would like to know specs on NOS generator bolts, rubber bushings, and the two styles of washers. Then I think we will need to gather the same specs for what is being offered for sale as repops on these generator mounting parts. This will allow us to continue to mount our generators with the NOS, Repops, or combination of these parts into the future. Confused? It should become clearer with a few nifty drawings Sean has. Sorry I have spoken too soon on making these washers, it was always my intent to make these washers so they will work properly on your application as well as mine. Give me a little time to figure out what is more correct. Help us figure this puzzle out with some data. |

I'll be starting a "request for data" in the research section. May not need to now.
Have to finalize a few drawings first though, will try to get that done today. Sean

After "dumpster diving" into unsorted parts piles, I found more originals parts! (and discovered incorrect dimension repro bushings! Imagine that )
Photos will enlarge. A-1397 bolts have the same .030" radius as the previous bolts: A-1401 small-hole washers are chamfered, just like the ones depicted on the G. Note the narrow circular contact patch where the washer rested against the bolt shoulder. 1.130" (+/- .005) OD the other side: So the chamfer can serve both as a bolt guide, and to insure no interference with the radiused shoulder. A-1396 large hole washer. Note the circular contact patch from the bolt head: 1.125" OD Bushings: I have 1 NOS and 1 repro. The repro is .050" longer than NOS. Joel has a repro that is .100" longer than NOS! These "too long" repros could cause installation difficulties. The DO have to crush when the nut is fastened down. The general idea:
These are fairly hard bushings, IMO, the repros would require too much crush, specially that last one! Gotta run for the day, but will have more drawings & thoughts later. Sean

I'll take two sets. I wanna support this professional effort.
Nice drawing. Once one sees the drawing, the chamfer is obviously needed because it clears the fillet on bolt step. I'll need to look at my rock stock CJ2A to see what I have, but it is really cold in my garage. Walck should buy your extra stock after you go through this work.

Fellas, did anything ever come of this effort? Were any of these washers produced? Does anyone sell them now?
As you may guess, I need two sets for my CJ 2a Generator. Thanks!

Dredging up an old thread. I realized my generator was not well mounted, so started researching and ended up here. So, did anyone make these washers?

Ron Fitzpatrick sells them but they may be a part of a kit.

I ordered the washers and special bolts, as well as a few other things from RF. I probably wouldn't have known there was a problem with mine. But I noticed the generator was cocked a little, not quite parallel to the engine. So i crawled underneath and found the bolts loose and one close to falling out.
I can't help but wonder why Willys felt the need to use this complicated mounting system. I've owned quite a few antique cars and trucks over the years. They all had generators using the same basic mounting layout, but all just used a solid bolt up mount, no rubber bushings, special bolts/washers. I can't imagine the go-devil vibrated more than other engines of the era. Perhaps it was a carryover military requirement from the MB era. It had to be more expensive to manufacture this way. |
