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.
