datsuma Posted July 2 Report Posted July 2 Hello I'm doing my first clutch job, A15 with a 60 series 5 speed. None of my manuals say how much travel is normal, between the sleeve/throwout bearing and it making contact with the pressure plate fingers? It's at least an inch. I know i can take that slack away when i adjust the clutch cable, it just seems like a lot of freeplay. Wanted to make sure it seems ok before i get it back in. Youtube short link below, really appreciate any help. Youtube short showing the freeplay. Quote
datzenmike Posted July 2 Report Posted July 2 Cable? or is it a mechanical push rod?? Isn't the 1200 hydraulic operated? On the hydraulic clutch the clutch arm is pushed towards the rear to disconnect the clutch disc. How does pulling the cable work? Quote
datsuma Posted July 3 Author Report Posted July 3 It's just a cable, from the way it hooks onto the clutch fork i assume it can only pull towards the engine? Quote
datzenmike Posted July 3 Report Posted July 3 Agreed. However all hydraulic clutches push on the clutch arm. So how does the clutch arm work, I wonder. Quote

Looks like from diagrams (below) the clutch fork is in a different position for the cable and therefore the pulling motion is transferred in the opposite direction as the pushing of the hydraulic slave cylinder. http://datsun1200.com/modules/mediawiki/index.php?title=Clutch_Cable As the site is not currently loading: https://web.archive.org/web/20241010112543/http://datsun1200.com/modules/mediawiki/index.php?title=Clutch_Cable Quote
datsuma Posted July 3 Author Report Posted July 3 Wish i got a video before i put it back together, lessons have been learnt 🙂 The bearing sits on a 48mm sleeve, the sleeves held onto the clutch fork with a spring (that returns the sleeve). When you pull the fork towards the engine, the whole sleeve and bearing slides towards the clutch. I'm trying to explain something i don't entirely understand sorry. Which all seems to be working fine, it's just a lot of freeplay and i don't know whats acceptable. I can't buy a longer sleeve, 48mm is what it previously ran and is also the largest sleeve available. Quote
datzenmike Posted July 3 Report Posted July 3 If the clutch arm attaches to the right side and the sleeve and bearing are in the middle, if you pull the left end forward by cable, then yes it would work. The hydraulic clutch arm is like a see saw. If pushed back by the slave it transmits forward motion to the other end. Surely not all 1200s are cable? None of my references mention or show a cable. datsuma: you should fill out your location in your profile. Are you in New South Wales??????? Quote

Yep, seesaw is a great analogy and exactly how I was imaging it, looks like from site it was a RHD thing only. The cache site loaded more pics today so I pasted another in which shows it on the transmission. Datsun1200.com still seems to be down though. 1 Quote
