parts list question

[Dan S]

Hey all,

I am currently assembling all fastners I will need for front and rear suspesion, but key # 15 on page 92-4 of the microsiche cd is not shown in the picture. It is listed as PN# 55417-E4100 washer-special D qty of 4 needed.

Am I just getting older and my eyes don't see it there. Could someone help me here and tell me where this washer is used. It is the one part that is holding me back from placeing my order.

Any help would be great, Dan

That's odd. I have four hard copy parts catalogs LHD and RHD from 11/69 to 6/74 and that part number is labelled as key 13 in all of them, yet it does not show up in the illustrations in any of them. Maybe you should just go ahead and try to order the four it says are required and see if they match anything if you are able to get them.

Exactly the problem, are they available, or can the be reproduced?, If I had some idea where they are used or what they look like the I might be able to find they in the dreaded "misc. nuts and bolts" box.

A search at http://www.nissanparts.cc/

shows that it "produced no results".

Courtesy Nissan came up the same.

The listing of that key number is in the area of the differential mount.

I'll be interested to see what it is as I am ordering parts for this area as well soon.

Probably NLA, but let us know if this gets resolved.

I put the microfiche in my reader and studied page 92-4. PN #55417-E4100 washer-special D is not shown. Also not shown is the nut that goes with the hex bolt (key #20). If you look at the bolt, corresponding washers and visualize the hex nut which is not shown, it is fairly easy to see how a D washer would fit under the hex nut. I will look through my hardware which I labeled and cataloged to see if I have the "special D Washers". Of the hex bolts and washers Key # 20, # 21, #22, 4 of each were used up to 07/73 and they were changed as of 08/73. My microfiche is the latest revision (Dec 79) and there is no further mention of PN #55417-E4100 or replacement. I think it is just a flat washer filed flat on the side to fit.

PS - It is key # 15 on my microfiche, not 13 like in Mike's hardcopy, or did you mistype?

Hi Ron,

If that comment was directed to me, no it was not a typo on my part. Part #55417-E4100 (Washer-Special D) is key no 13 in the following hard copy parts catalogs:

Datsun Sports 240z - US and Canada - Nov 1969 (pg 62-1)

Datsun Sports 240z R-Drive - Dec 1972 revision (pg 62-2)

Datsun 260z*240z - US and Canada - March 1974 revision (pg 62-2)

Datsun 260z*240z - US and Canada - June 1974 issue (pg 62-2)

It is also kind of interesting that the Nov 1969 catalog has an asterix in column S for that part number, which means it is a non-available item or old item superceded by a new one. However, there is no new part number shown and none of the other three have this same asterix, so maybe it is a type in the first catalog and then the illustration was never updated (at least in the four that I have).

I am certain that I have located PN#55417-E4100 and also have an explanation why it faded out of existance. Thanks Mike, yes on the microfiche page 92-4 it is key #15. Mike, you are the perfect guy to verify this theory I have. I went to my garage and located PN 55411-E4100 assy-member differential mounting front. It is key #14 on page 92-4 of the microfiche. By flipping it upside down you can see PN 55417-E4100 washer-special D (all 4 needed). They are actually spotwelded to the assembly. My thought is that on the very early cars they were not welded to the assembly, but were separate special washers. This is something you could possibly verify at some point in the future.

Anyhow Dan I don't think you are missing anything. Just make sure the hex nuts are accounted for because they are not listed on the microfiche either.

Hi Ron,

That is a very interesting theory I hadn't considered. I'll try to confirm it as time allows. In addition to my two 11/69 cars I have a 9 or 10/70 parts car I can check. I also have a NOS differential assembly I can check. I think it is one of the later ones 55411-E8300 (7/71 -7/73) or 55411-N3001 (5/73 - ??).

Thing is Mike, you can't check that out unless the rear is dismantled. Mine is dismantled so it was easy to find. The part is in a bin waiting for me to media blast. I'll see if I can get a pic and post it here, showing the Special D Washers.

[geezer]

I don't know what I was thinking about the hex nuts. There are none. The hex bolts thread into the captured nuts in the rear frame. Here is a pic showing two of the Special D Washers. Mike, I guess only one bolt has to be removed to see if a Special D Washer is spotwelded to the assembly or not. If my theory is correct, who knows how early on they started welding them on.

[Mike B]

Ron,

I found the NOS suspension assembly I have and it is actually the front assembly, not the rear diff mount, so I'll have to check out the cars to see what is on them. I also have a couple of dealer price lists. One dated July 1, 1982 lists PN#55417-E4100, but another dated Jan 1, 1990 does not list it in either the parts list or the supersession listing.

[Dan S]

I knew I could count on you guys.

Thanks Mike and Ron for clearing this up for me, I now see what is going on here, and yes flipping over my front diff member I see 4 spotwelded washers.

Thanks again guys, and now on to the ordering phase as I would like to get all undercarriage painted and installed this year.

No doubt I will be back asking questions at the next hurdle, hopefullly not too many of those.

Dan
