Llittle_Llama Posted May 19, 2011 Report Share Posted May 19, 2011 I found this at the JY today and before I pull/pay for it tomorrow I want to make sure this is correct. I know it's an L series, but I'm not sure if that's the only thing I need to know about it. Besides checking that it shifts into all the gears fine is there anything I can do to make sure I'm not pulling a POS? Quote Link to comment

I want to say around 3-4 inches. If your familiar with 521's , you can kinda see where the original spot is supposed to be. Quote Link to comment

That's not bad at all. I've half-heartedly looking for one. Full force now. Buy yes. I own a couple 521's. Quote Link to comment
Hoosier77 Posted May 20, 2011 Report Share Posted May 20, 2011 take out the drain plug and drain the fluid into a clean container and see if there is any chunks or particles of metal. dark colored fluid is normal, chunky, milky, and metal grit is not. Quote Link to comment
Llittle_Llama Posted May 20, 2011 Author Report Share Posted May 20, 2011 1/2 inch ratchet for the drain plug right? Just a square hole right? Quote Link to comment
datzenmike Posted May 20, 2011 Report Share Posted May 20, 2011 Look at drain bung it has a magnet on the end that traps ferrous metal. It will normally have a black 'paste' on it. Maybe some fine particles. Relatively normal bung Not so normal bumg. My bung. picture removed by request . 1 Quote Link to comment

Measure the front shaft of your driveline(assuming you have a 2 piece). Next time you hit the yards, grab a front shaft with carrier bearing from a 620 that is approx 4" shorter than your stock one. This way you don't have to pay someone to shorten your stock one. I just can't remember which truck I pulled mine from. King cab and regular cab could be different. Sorry for the thread jack,dwnshfter Quote Link to comment
datzenmike Posted May 20, 2011 Report Share Posted May 20, 2011 Jeffe, I think they (front) are for the most part the same length. The differences in truck lengths are in the frame behind the carrier bearing on the reg or KC cab. I would thing the rear driveshafts are different lengths. Quote Link to comment

I swear, my memory is $hit. Ok, grab the the driveline half that's 4" shorter than your stock one. Quote Link to comment
Pacific coast Datsun Posted May 20, 2011 Report Share Posted May 20, 2011 Also make sure to use the TRUCK [620] throw out bearing & clutch slave cylinder. Quote Link to comment
Llittle_Llama Posted May 20, 2011 Author Report Share Posted May 20, 2011 So my reg cab 620 has a carrier bearing? Will I need to to swap out the driveshaft? What's this 4 inch deal? No dick jokes please ;) Quote Link to comment

Don't change anything. You have a '79 right? The zx will swap right in... it's the same exact length as your old 5 speed. HOWEVER Being a '79 you are running a 4.11 ratio rear end and the 5 speed (or 4 spd) you have now is differently geared to allow an easier take off in first. Installing a ZX will be a mutherfucking huge jump in gear ratios. Your overdrive ratio is about 12% the zx is twice that at just over 25%. You may have trouble maintaining highway speeds into a light wind. '79 ratios 1st.... 3.594 2nd... 2.246 3rd.... 1.415 4th.... 1.000 5th..... 0.882 '81- zx ratios 1st..... 3.062 2nd... 1.858 3rd..... 1.308 4th..... 1.000 5th..... 0.745 Quote Link to comment
Llittle_Llama Posted May 20, 2011 Author Report Share Posted May 20, 2011 You meant 4 speed right? I thought it swapped right in, but it's been so long since I was looking at doing this so I wasn't sure. Quote Link to comment

Oh yours is a 4 spd??? Well exact same gears without 5th. Don't you mean by popular request? :blink: ........ (yes) Quote Link to comment
