moparvwfreak Posted December 8, 2008 Report Share Posted December 8, 2008 i know my clutch is just about done. its been grinding sometimes going into gears even with the truck stopped and the clutch in. but that's not what i am asking here. what i need to know is COULD a clutch make a sound like a knock? my little truck is making some funky noises and the knock i hear started about the same time she started grinding going into gear. also, i need to find a 5 speed transmission, CHEAP OR FREE, that will bolt in place of my short tail 4spd. is there such a thing??? i figure this would be the time to replace the trans with a 5spd. i just rebuilt my drive line and don't want to have to mod it to fit a later model 5spd. this is the time i wish i had a 74+ truck. any ideas where i could get one or what its out of? i dont mind a dogleg if i have to. it would just take a little getting used to.

Skib Posted December 8, 2008 Report Share Posted December 8, 2008 its posable its making a knock sound but you cant say for sure until you check it out. finding a 5 speed for cheap even could be a task. Quote Link to comment
moparvwfreak Posted December 8, 2008 Author Report Share Posted December 8, 2008 i have tried to find it but cant seem to pinpoint it. i guess she'll ahve to go up on ramps or stands so i can get under while shes running and see what i can hear. Quote Link to comment
datzenmike Posted December 8, 2008 Report Share Posted December 8, 2008 A '77-'79 200sx dog leg 5spd will be the same length as you '73 tranny. What you really need is a short tail FS5W71B. I have a picture of one supposidly from an '80 720. When does it knock? Only when you use the clutch? All the time? Quote Link to comment
rat tail dragger Posted December 8, 2008 Report Share Posted December 8, 2008 I have a fully rebuilt 4 speed with short shifter short shaft came out my old 73 for $50 bucks Quote Link to comment
moparvwfreak Posted December 9, 2008 Author Report Share Posted December 9, 2008 clutch died today. and it was only knocking with the clutch out. so i figured it was a clutch issue. so yeah its fucked. plus the trasn is leaking out the front seal. and its whining BADLY. not a good day.

datzenmike Posted December 9, 2008 Report Share Posted December 9, 2008 That's shitty news. On the bright side, you can up-grade to 5spd now. Quote Link to comment
Cuts metal like mad Posted December 9, 2008 Report Share Posted December 9, 2008 You can also do the long tail if you get the driveline and I believe trans crossmember... Quote Link to comment
datzenmike Posted December 9, 2008 Report Share Posted December 9, 2008 A '74 and up drive shaft will be the right length. You may be able to just change the shorter front half with the carrier bearing on it instead of the whole thing. Even if you get the 4spd, tranny mount and drive shaft of the same wreck, it would get you mobile. You could then keep your eyes open for a 5spd. which will fit right in where the 4spd is, no mods.

moparvwfreak Posted December 9, 2008 Author Report Share Posted December 9, 2008 That's shitty news. On the bright side, you can up-grade to 5spd now. yup. it is. and i can but want a short tail trans. You can also do the long tail if you get the driveline and I believe trans crossmember... yes but i would need drive line and i just rebuilt mine. not a real desireable swap at the moment.

Even if you get the 4spd, tranny mount and drive shaft of the same wreck, it would get you mobile. You could then keep your eyes open for a 5spd. which will fit right in where the 4spd is, no mods. true. but there again i just rebuilt mine. god this sucks! Quote Link to comment
moparvwfreak Posted December 17, 2008 Author Report Share Posted December 17, 2008 well i replaced my clutch master and it didn't help. i think maybe the clutch itsself is gone. this sucks. i have a FULL tank of gas in it and cant drive hte damn thing. i have a long tail trans available so i guess i get to find another driveshaft. at least a front piece. Quote Link to comment
Cuts metal like mad Posted December 17, 2008 Report Share Posted December 17, 2008 I have a couple 521 driveshafts... You can have them, or the piece you need... Might help. I read someone saying that the 521 driveline is the same as a longtail 620. ??? Quote Link to comment
datzenmike Posted December 17, 2008 Report Share Posted December 17, 2008 The 521 may match the '72.5-'73 620 because they used the same short tail tranny. After '74 the driveshafts were about 5" shorter to accommodate the longer 4 speed tranny. Quote Link to comment
moparvwfreak Posted December 17, 2008 Author Report Share Posted December 17, 2008 i remember reading somewhere, i cant recall where (really i dont), that the clutch fork is prone to breaking. is anything like that true? i am more than willing to do a clutch on teh truck and i ahve a trans i can swap in as soon as i can get it. i just need the front of a long tail driveshaft. also do i absolutely need a long tail cross member? i can get one and a front drive shaft from a KC out at the bone yard if i have to.

moparvwfreak Posted January 20, 2009 Author Report Share Posted January 20, 2009 talked to my buddy and the guy literlally threw the trans away. so i am in need of at least a clutch, possible trans, and a hand. i need to get this truck on the road ASAP with no funds. i think the clutch may be good but something broke between it and the slave. if i can get it to shift again i'll drive it till it dies. i dont care. i am just getting a headache driving my rabbit pickup around with a bad exhaust leak and a rattleing exhaust. io want my datsun back.

datzenmike Posted January 21, 2009 Report Share Posted January 21, 2009 If it put your mind at rest I have never heard of one clutch arm breaking. Quote Link to comment
moparvwfreak Posted January 21, 2009 Author Report Share Posted January 21, 2009 then something must ahve broke on the clutch itsself. time to yank the trans out. what fun........ this will make #2 trans i take out this week. if i have time anyway. Quote Link to comment
datzenmike Posted January 21, 2009 Report Share Posted January 21, 2009 (edited) Did the release bearing collar detach from the clutch arm when installing, maybe? Did you install a new release bearing? Did you pack it with grease first? ....so yeah its fucked. plus the trasn is leaking out the front seal. and its whining BADLY. not a good day. That does sound like thew input seal is gone. Perhaps the bearing went and took it out. See datto510 on here. He has a tranny for Hainz but he may not need it.

moparvwfreak Posted January 24, 2009 Author Report Share Posted January 24, 2009 well i think i figured out what happened to my clutch. i THINK the pressure plate broke. i have trans out now and no the top bolts were NOT an issue as of yet. the hardest thing right now is getting the trnas back in with the exhaust in the way. i should drop it BUT its all welded together and i have no more $$ to play with it right now. i am HOPEING to get the truck going by later today.
