DaEvil Posted August 4, 2005 Share Posted August 4, 2005 Not sure if this will help anyone but this is what I did. Purchased a VLSD cheap (just the guts). Installed it in my R200. Got 2 output shafts 5 bolt from 92 300z and 4 axles. Made some adapters to go to the wheel side then cut and resplined the axles (27 splined). I have not driven the car yet but I think it should work. Here are a few pics Quote Link to comment Share on other sites More sharing options...
blueovalz Posted August 4, 2005 Share Posted August 4, 2005 Is the adapter plate on the splined side of the companion flange, or the shaft side of the companion flange? It appears to be on the splined side, which I find hard to believe I'm seeing this photo correctly. Edit, oops, I see it better now. Disregard! These adapters look very much like the ones I've had machined for the 930 joints. Can you show photos of the adapters themselves? My main question is what was required in terms of clearance for the nuts (the ones used to hold the companion flange onto the adapter) and the amount of material left after relief cuts for the nuts were made. Did you use studs instead of bolts? Quote Link to comment Share on other sites More sharing options...
5foot2 Posted August 4, 2005 Share Posted August 4, 2005 Is the internal swap of the vlsd pretty straight forward? I have a complete r200 out of a 93z and 4 axles and I'd been thinking of something like this for a while. Quote Link to comment Share on other sites More sharing options...
DaEvil Posted August 5, 2005 Author Share Posted August 5, 2005 yes its easy , I used my old ring gear just unbolted it. I had to make small bushings or spacers the old bolts were 10mm and the new onds were 12mm when i bolted it up to the new unit Is the internal swap of the vlsd pretty straight forward?

DaEvil Posted August 5, 2005 Author Share Posted August 5, 2005 I'll take some pics tomorrow and maybe that will answer some of your questions. I used grade 8 bolts no studs Is the adapter plate on the splined side of the companion flange' date=' or the shaft side of the companion flange?

BlackBeaut Posted August 5, 2005 Share Posted August 5, 2005 Cool! How the heck do you go about resplining the shafts though? Is there a cunning machine or is it a matter of using a rotary/index plate thing and a milling machine to cut each slot individually? Cheers, Rob Quote Link to comment Share on other sites More sharing options...
DaEvil Posted August 5, 2005 Author Share Posted August 5, 2005 Yes I cut each one LOL and used carbite cutters because of the hardness Cool!

5foot2 Posted August 5, 2005 Share Posted August 5, 2005 did you have the shafts hardened after they were cut and worked? Quote Link to comment Share on other sites More sharing options...
DaEvil Posted August 6, 2005 Author Share Posted August 6, 2005 NO they never got hot enough to where they lost their hardness did you have the shafts hardened after they were cut and worked? Quote Link to comment Share on other sites More sharing options...

RB26powered74zcar Posted August 6, 2005 Share Posted August 6, 2005 Can you take a pic and show the shaft side by side, before and after. I'd like to see/ know how much off the lenghth you took if you can... thanks oh, and which end did you cut, inboard/ outboard?? thanks again joel Quote Link to comment Share on other sites More sharing options...
Briguy280Z Posted August 22, 2005 Share Posted August 22, 2005 I picked up a q45 r200 from the jy and some companion flanges from a 90 300zx na 5 bolt. I would like to use the r200 long but i am a little fuzzy on a few things. The 12mm bolt spacers - not sure where to find these. Have a machine shop make them? The companion flange couldn't you thread the companion flange or would the alluminum be too soft to do this? Are they about 1" thick? Is there any advantages between the 5 bolt and 6 bolt cv units?The q45 will have the 6 bolt and the 300zx has the 5 bolt. Having a problem finding someone to make axle shafts. Any suggestion? I would really like to see a picture of the q45 innards in the r200 long casing. Does the axles differ in length than tim240z setup? This is a matter of opinion but should i buy another r200 long and fit the q45 in that....would this make the process easyier or no difference? Thanks Brian Quote Link to comment Share on other sites More sharing options...
DaEvil Posted August 23, 2005 Author Share Posted August 23, 2005 it can get a little confusing. First you said you got a R 200 from a Q45 from the JY did it come with the output shafts ? You will need them and that would also determine if you are going to need 5 or 6 bolts flanges. It is a VLSD correct ? Quote Link to comment Share on other sites More sharing options...
Briguy280Z Posted August 23, 2005 Share Posted August 23, 2005 So far this is what i have Have 1-R200 from 280z 1-R200 from Q45 2-companion flanges from 300zx (5 bolt) not Threaded 2-companion flanges from q45 (six bolt) Threaded Need 1-Driver side Axles (Size??) 1-Passanger side (Size??) 2-Adapter for companion flange (5 Bolt) 2-12 mm spaces for bolts (ring gear) So far $300 Broke two tools trying to get the differential out--grrr Quote Link to comment Share on other sites More sharing options...
