My '72 240z has a 5spd from a '81 280zx. I just recently replaced the clutch master with one for a 240z as well as a clutch slave for a 240z since the one on the car had the threaded adjustable push rod like one for a 240z. I also swapped the longer push rod from the old master cylinder to the new one. After several bleed and adjustments I am at a point that it goes in to gear fine except for reverse. The threaded rod on the master cylinder is maxed out. My question is, should I get a clutch slave for a '81 280zx? Since my fork has a hole in it for the threaded rod to go through I suspect the answer is no but wanted to post the question here. Another issue which I d…

I recently purchased a factory 1971 Nissan Service manual. I was surprised that there was no section on rebuilding the automatic transmission. I have one 240z that is getting redone with the factory automatic transmission. I was trying to find the info on how to rebuild the tranny. Was there a supplemental service manual or possibly another vehicle that had the same tranny and would have the info for the rebuild work. Thanks, Charles

Just ordered a new driveshaft from Driveshaft Replacement of Texas for my '78 coupe. When I restored my Z, I replaced all the mounts on the engine, tranny and diff, but the driveshaft was wonky and is now bumpin and thumpin. Although my diff mount is near new I am thinking that my next upgrade will be a Technoversions Diff Mount - (BUT their website is down so if you have a contact #, I would be much obliged). Driveshaft Replacement of Texas is charging $279, the driveshafts are built to order using new parts, replaceable u-joints and is speed balanced. The price also includes shipping. I will do a follow-up post with comments on quality of workmanship, fitment, etc. …

Please see the attached picture. Is the item I circled in red the vacuumcock? I'm trying to find were the hose coming out of the top is supposed to connect too (identified with the red arrow) I'm looking at the AC FSM for a 1974 260z, mine is a 1975 280z. I'm thinking it could also be a check valve on page AC-34. Kind regards, Robert

I've been asked by many members and non members about my ignition set-up and after writing the info so many times, I figure it would'nt hurt to post the needed info here at CZCC. And now you can send this thread link to others who may be looking for the same info. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I typically put a lot of praise on the Unilite, versus the worn bearings and parts of the stock distributor. Changing the set-up from points to infra-red is always a great idea but it's like putting a New head on an Old block, the head can't perform optimumly because the pistons and rings are worn. The optical pick-ups of the Unitlite and the Pertronix are are basi…

I own a 1971 240z and this past winter I swapped out the trans that was in it (datsun b 210) with the original z trans. The PO told me the original had been overhauled and he never got around to putting it back in. To make a really long and agonizing story short, the z trans was no good and I ended up putting the b 210 back in. But while I had the trans out I decided to replace the clutch disc and the throw out bearing. Easy job. But now when I drive the car, I get a wicked burning smell like I'm smoking the clutch. My guess: old flywheel and new disc aren't happy together. My question: should i just ride out the rough honeymoon and eventually they will have a happy marr…

Good evening everyone, I was trying to install the above mentioned U-Joints in my half shafts, but they seem to be a hair long I was only able to get the retaining clip in on one side. Has anyone had a similar problem, any ideas, or do I just need to start over with a different part number or brand. Any suggestions would be appreciated. Thanks Craig

My 280z is running rich. Is there a way to reglulate fuel mix to the engine? I see no vacuum leaks and idle is silk smooth.

I just replace Clutch Master and slave cylinder and bleed them with HFT Pneumatic Brake Fluid Bleeder I notice something strange. The slave cylinder is fully extended. No wonder whenever I push clutch pedal, it was too loose. Looking at FSM, I could not find diagnostic what's wrong with this symptom. Do I need to remove engine and transmission to investigate release bearing and clutch folk? I just want to drive my 280z before deep dive onto engine and trans Thanks for your advice in advance, tamo3 '75 280z with 4 speed trans.

For the archives: When following the FSM instructions and installing a new timing chain, this works: 0. Configuration: Head is on block with two middle cam tower head bolts at 14ft-lbs; head assembled; Cam sprocket is torqued to 100ft-lbs, Crank sprocket and Woodruff key is in place. Cam is at #1 and crank is at TDC. 71 L24 block with N47 maxima head. 1. Do not install chain guides or tensioner. 2. Drop chain through hole in front of head. 3. Wrap chain around crank sprocket with bright link next to dimple. 4. Firmly pull the chain up and wrap around cam sprocket with bright link next to #1 dimple. FYI the timing chain guides and tensioner prevent the chain from reaching…

Specs: 1977 Datsun 280z, 4/77 L28 Engine, everything original / stock Oil change 100 miles ago - 4 qts of 10w30, new oil filter Issue: For a few days now, i'm noticing that the Oil Pressure gauge shows the oil pressure dropping from ~40 psi down to ~5 psi over the course of 15mins of variable speed /rpm driving. Engine is sounding less smooth, running a touch rougher at idle. After reading previous threads, it looks like there's a few things i need to check first: 1) Check oil w/ a mechanical pressure gauge 2a) If mechanical gauge matches readings with stock electrical Oil Pressure gauge, then look at Oil Pressure Relief Valve to see if it's functioning. 2b) If mech gauge…
