We need Mike Klotz to make some cotter bolts I need 4 of them.  The fulcrum pins you can contact the Mexican ebay seller I think it is Kentigo.  He might have some.  He stands behind his parts a buddy of mine purchased a 521 fuel sending unit that was bad and Kentigo sent him another no charge.

would be nice to have some more made, what is the actual job of the cotter bolt ? is it to keep the pin from spinning during tightening ? cause it seems like when you tighten down the two caps things there is no way to have side to side movement ? and maybe a safety feature if those come loose it does not move ? 

 

nissan does have a couple more of the seals for the upper arms for the kingpin trucks if anyone needs those, and looks like the lower seals are nla

I know what a cotter pin is. :)

What are "cotter bolts"?

OK, I guess I never really thought about what them were called before, I guess I thought of them as a pin, but they are a bolt of sorts.

The 320 ones are smaller than the rest of them, I go to great lengths to remove them in good condition, which is not easy.

 

These are Cotter Bolts used to hold in King Pins and Fulcrum Pins.

This is true :lol:

Wayno, I thought when your truck needed any kind of suspension/steering work you just rolled a 720 chassis under them!  LOL

My 521 work truck is the only truck with a 521 frame, it's highly modified, but it is a 521 frame.

 

BTW, I have only done one kingpin R&R, I now have Mike Klotz do them when I buy a set of drop arms/disc brake brackets from him, it's really hard to do them when all you have is hammers and a vise.

Charlie... I would have to call those cotter pins. A cotter, is a pin or a wedge used to secure parts together. A cotter bolt would have some sore of head to turn it or secure it so it won't turn while tightening the nut. There would be a hole through the threads for a cotter pin to fit.

Just calling them as the parts manual does.  Also doesn't the threaded portion for the nut lean the name towards a bolt instead of a pin?

 

Part # 40023-30000

 

My parts calls it Pin Cotter, Fulcrum Pin

 

This is the name used in the Nissan/Datsun Parts Manual.  Part #  40023-30000.

 

Mike Is there a superseded parts number for these?  That part # comes up bad at Nissan Parts Zone.

 

Pt. # 40023-30000 is only used on the J13 and L16 520 and 521 and appears to not be superseded nor used in any other application. The 620 'pin' is 40023-B5000. Unknown if it will work... doubtful.

Mike obviously Canadian Manuals are translated differently than the USA Manuals  as all manuals back in the day were originally written in Japanese and then translated to the language of the Country they went to..  Is your library perhaps in French Canadian?

 

Mike it does not matter what it is called because we can not buy them any more . If I am successful at get some made I thinking of calling them "Charlie's Wedgette."

 

This is the manual that I took the wording from.

I've noticed on more than one occasion the cotter pin doesn't tighten down all the way in the hole and make full contact with the king pin. You can test this by sticking the bare king pin and tightening the cotter bolt down most of the way not all of the way and you'll see the the cotter pin is snug but the king pin moves around a little.

 

I sand/dremel my cotter pins a bit for this reason.
