jun Posted September 9, 2011 Report Share Posted September 9, 2011 nice work on that frame! I too have a 620/720 4x4 combo (purchased from a fellow Ratsun member) and wanted to clean up my frame. Your project is a nice point of reference, but I'm definitely not ready for that amount of work yet. Quote Link to comment
Master-O-Turbonics Posted September 11, 2011 Author Report Share Posted September 11, 2011 finished pulling crap off the frame last night The stock open 4.375 R180 differential(would be great for autocross or lower speed road racing courses for a 240Z, probably going into my parts collection) a bit more progress and a peek into our fab shop Also found and ordered an old Nissan manual on rebuilding/shimming the transfer case... Old Nissan manuals like that are hard to find. Quote Link to comment
wayno Posted September 15, 2011 Report Share Posted September 15, 2011 Is the SD22 diesel engine going in this frame? You will have to extend the motor mount surfaces forward for the diesel, if you remind me tomarrow I will take close up photos of the diesel mount surfaces, as they are differant than the L20b/Z22-4 block surfaces, they are slightly differant angle, and 3 or 4 inches forward. Most of the guys that have put a diesel into a 4X4 frame have used a hybrid 4X4 napZ gasser/diesel oilpan combo, which seems to take time to make. Quote Link to comment

Ah thanks, I had noticed a difference between the rustyyyy front clip that the engine is on and my frame rails, but did not really investigate it much further than that. I'm losing all the Independent front suspension stuff so I really don't have to worry about the oil pan clearing the differential. I'm going in to the shop tomorrow to finish grinding/cutting on the frame and hopefully get it sprayed with epoxy primer before going out of town early next week for a test at Kansas Speedway with our newest race car.

Master-O-Turbonics Posted September 18, 2011 Author Report Share Posted September 18, 2011 more work done today flipped the frame over and did more grinding/ cutting off the IFS Test fit the diesel motor and looks like motor mounts are right at 1 3/4" further forward than the gas motor, so I'll be doing those next time I get to work on the truck Quote Link to comment
wayno Posted September 18, 2011 Report Share Posted September 18, 2011 What are you going to use in the front to hold the wheels? Quote Link to comment
Master-O-Turbonics Posted September 18, 2011 Author Report Share Posted September 18, 2011 What are you going to use in the front to hold the wheels? A Dana 44. :-D Quote Link to comment
wayno Posted September 18, 2011 Report Share Posted September 18, 2011 So this project(yours) is going to be high, this is what my 521 diesel(SD25) looked like at one point. This is what it looks like today, I just don't like high myself. Quote Link to comment
Master-O-Turbonics Posted September 24, 2011 Author Report Share Posted September 24, 2011 Acquired a decently built Hi-steer Waggy Dana 44 with aussie locker. (wheel has too much backspace and hits the stock steering arm, hence the funky camber) GOTTA get the motor mounts done! Quote Link to comment
wayno Posted September 24, 2011 Report Share Posted September 24, 2011 How wide is that axle? It looks really wide, is this truck for the road? Quote Link to comment
Master-O-Turbonics Posted September 24, 2011 Author Report Share Posted September 24, 2011 How wide is that axle? It looks really wide, is this truck for the road? Its a little bit wider than a stock rear end. Quote Link to comment
HRH Posted September 24, 2011 Report Share Posted September 24, 2011 I'm glad you're putting a solid axle under the front. I was going to mention, the reason you see 720 4x4s for sale all the time is one because the 4wd parts are hard to come by. Particularly 80-82 with the early 4wd system. I can't even find half shafts for those anymore. 83-86 were better, but still didn't get the extension housing the D21 did. D21 axle shafts are a dime a dozen though, which is nice. And it's also nice not to have the 4wd drive pull to one side as with the unequal-length shafts. Quote Link to comment

The deciding factor was when I went to NAPA and they laughed when I asked for CV axles for an 81 720 4x4... LOL. I spent way more than I did on the truck just for the axle, but its 4.88 ratio matches an H190 chunk that I have, its already built, and I can spend my time working on a 3 or 4 link setup. With the axle I also got a ruff stuff 1/4" thick differential cover, which isn't a cheap part either. Quote Link to comment
Sealik Posted September 24, 2011 Report Share Posted September 24, 2011 Sucks having no extra shafts 'lying' about :P Got many 83-86s...and a couple sets of 81-82 left. 81-82 will also fit the 80....just swap sides IE.....Right to left....or...left to right side Quote Link to comment

Pulling to one side or the other wouldnt be due to the length of the shafts, but because the front diff doesnt lock.... I still would love to just do a SAS on my 720, but thats just too much money when I currently have an engine rebuild on the table. Quote Link to comment

V8 probably in the future of this rig but 65hp 100fl/Lb torque should be good enough for me for now. :-D Quote Link to comment
Sealik Posted September 24, 2011 Report Share Posted September 24, 2011 So are you saying you know how to lay 30 year old shaft? Geez. Your interpretation of my statement somewhat implies a latent (subconscious) desire to have a so called 'shaft' fitted where it doesn't belong. Sorry.....not interested.......but....whatever floats your boat. :lol: :lol: :lol: Quote Link to comment

Master-O-Turbonics Posted September 26, 2011 Author Report Share Posted September 26, 2011 What is this paint code? It has a paint code sticker under the hood but the code itself is not there. I would love to paint the truck back to the original color. :-D Quote Link to comment
