Bolts

[albersj51]

Great thread! I am taking my 67 S2A down to the frame in a few weeks and I want to replace all of the body To frame bolts (have a feeling I'll be destroying a lot of them). Mountain132 was kind enough to email me the PDF . As I was creating a file of all the bolts to order I realized s3 bolts may differ from s2a bolts. Can someone confirm that LR didn't change bolts/threads from models? Also, if anyone already has a list of what I would need that would be awesome! Mainly want to make sure I have anything that connects to the frame or anything likely to strip or require cutting off. If not, I'll post my file for general knowledge. Thanks!

Great thread! ......

Agreed, part of the beauty of this site is discovering what you didn't know you didn't know. Thanks for lending your homework boyz...

OK, attached is an Excel file listing bolts, nuts, washers, screws, etc from the Belgian manual. This is not EVERYTHING, just what I think I need to remove/replace as I remove the body. Does this look like a good list? Also, I expected to see British Fine Thread type of bolts, but all are UNF and UNC...is this right for a IIA? Lastly, anyone know the length of the bulkhead to chassis bolt?

Give the file a look and let me know if it looks "right" or not. Thanks!

The SIIA and SIII parts manuals indicate which thread (BSF/UNF/UNC) is used over certain model years. For example the shackle bolts which attach the leaf springs to the frame may be BSF over a certain period of time then switch to UNF for later models. What they don't often show is the length and diameter which the belgian manual shows.

I would think that in any application where you are replacing both the bolt and nut that you could use any thread pitch as long as the diameter and length are consistent with the belgian manual. In applications where you need to mate a new bolt to a threaded opening such as the drive flange, then you need to make sure to get the right one. As you disassemble, keep the old bolts with the component even if you are going to replace them, it makes this process easier.
