I just had to replace mine last week for the same damn thing. Airtex is garbage.

For you North County San Diego guys, there will be free roadside smog checks with helpful CHP officers 'pulling you over' and asking you to submit your vehicle for a test. Location is at 1134 North Melrose Drive, Vista CA 92084 http://www.epa.gov/oms/regs/im/roadside.pdf

Little update to close this out so people can use the info later... Basically, poor maintenance, lack of grease, and age contributed to the failure. More likely poor maintenance. darrel was right in that no grease, heat/binding, snap-bang-clunk dead. Not sure what the trans is, but it is definitely mated to an 82-84 NAPZ bell housing. Front cover for the trans is 32111-E9800. Nissan lists the same part number (30531) for the clutch fork for a number of model years and 5 spd transmissions, but I'm not sure about earlier 4spds. Since I'm bumping this back up to the top, I thought I'd ask a new question about my center carrier bearing for the drive shaft. I'm broke. As in, "thousands of dollars in medical bills" broke and need to find a cheap solution to my bearing. The actual bearing is good and spins freely - it's just the rubber isolator that's toast. I've seen people use random rubber "things" in place of actually replacing the entire thing, but has anybody ever used a mountain bike tire? I have an old downhill casing Kenda Nevegals that I thought I could wrap around the bearing, gluing the layers as I wrap, then clamp that bitch down. Anybody have any experience doing this with decent results? Thanks again.

Here you go tdaaj. Sorry for the high jack...

^^^this. Looking through yahoo auctions Jp I notice a lot of American Racing, Moto Metal, even old Western Wheels selling for astronomical prices. Makes me think I should work out a trade with my Western Bullets for some JDM truck wheels.

Wish I had the skrill to get my grubby hands on these.

Thanks Darrel. I checked it yesterday and its good and I'm thought the same thing about the clicking as soon as I saw the damage. Nissan stocks the gearbox front cover, so I'm going to get down there to see if the have this exact one, and pick up a new fork while I'm at it.

Thanks for the responses guys. Yeah, the PO told me that it was a KA trans. He sounded convinced, himself, that it was a KA but you never know. I want to give the guy the benefit of the doubt because of who he is. I'm all the way down here in San Diego, so don't worry about the fork Len, though I do appreciate the offer. I'm just going to order one from Partstrain. I still need to measure the throwout bearing collar to make sure that it is the correct sized one. The PO used a threaded slave cylinder pushrod to increase the distance, which is why I'm not feeling to warm and fuzzy about the collar or the fork.

There definitely was NOT any grease for the TO to slide. That's for damn sure. That thing was dry as a bone. edit: and you're correct, it is aluminium.

How goes it, Ratsun? I have some problems and questions, and hopefully you guys can help. First off, I have a '73 620 with an L20b and what the PO says is a KA tranny mated to a NAPZ bellhousing (5spd of course). I don't know because there are no identifying numbers on the transmission, and I don't know how to eyeball these things. That's where I'm hoping you cans can say yes or no on whether or not that is what I have. Here are some external oics of my tranny. She's yellow, so she must be asian: On to the actual issues! First off, my clutch fork bent and cracked. I don't know why. I posted on here last year about my slave cylinder pushrod not disgengaging the clutch enough to shift. Well, now I know why. It almost seems like that it is the wrong size...? I measured from the dimple for the slave cylinder pushrod to the center of the main pivot, and it is about 4 3/4". In case you need to know, I have a 240mm clutch. I forgot to measure the length of the release collar, so I'll do that soon because I'm sure you'll need to know that too. Here's a pic of the sad fork: Secondly, and this is probably related, the shaft/collar that the throw-out bearing collar rides on snapped off at the base. I'm not too happy about that. Is there a Nissan part number for this cover, or is it even readily available? If not, who has an extra one lying around that they want to sell me? Here's some pics of this :poop: : I really don't want to source a new transmission... what are the likely causes of Mr. Clutch Fork getting bent? Wrong size something or another? Thanks guys. Rob

I like darrel's idea. I would get the new truck running reliably for daily driver/commuter use, and use this as an opportunity to swap out the toasted motor for a KA or something, unless you absolutely need a running truck now.

What mike said. It's like a bad version of a single pivot mountain bike suspension. I'd follow their advice and redesign instead of trying to make it work. No need for catastrophic failure if you know that's where you're headed.

I think Gojira has another one posted on the JDM Nostalgia Facebook page.

Do you have a build thread for this thing, Radim?

Perusing old pics of my hometown, Key West, I came across this picture from 1973 taken at the old main gate of NAS Key West Truman Annex.
