Icehouse Posted October 27, 2017 Report Share Posted October 27, 2017 Got two of these guys in a trade. Installed the first one and it seems to slip a lot. Any ideas on the brand or where to get more clutches? Installing the second one this weekend but would like to fix the other for my ute. Thanks guys! Quote Link to comment
datzenmike Posted October 27, 2017 Report Share Posted October 27, 2017 Tag says welded, definitely welded..... If a Nismo part then any Nissan LSD clutches should work or can be ordered. Quote Link to comment
Icehouse Posted October 27, 2017 Author Report Share Posted October 27, 2017 HAHA yeah that was the tag on the diff. Swapped out the center for the LSD because I didn't want 4.6 gears in my truck haha. The lot came with 4 diff's. 2 welded and 2 LSD's. 3.7's 4.11's 4.38's and 4.6's I might be a little off on the exact numbers but either way lots of gears to choose from. I would like the 3.3's for my truck if anyone has some laying around they don't want :) How do I tell if it's Nismo? Quote Link to comment
datzenmike Posted October 27, 2017 Report Share Posted October 27, 2017 The A10 with Z20 engines had 3.364 and the L20B engines were 3.545 all in H-165. Nismo? Is anything stamped on the internal parts? Quote Link to comment
G-Duax Posted October 27, 2017 Report Share Posted October 27, 2017 None of the larger Nismo LSDs I've had ever had anything stamped on them. Nissan/Nismo seldom made their LSDs, but were made by outside vendors. (used to know who, but those brain cells died a long time ago) That's why their helical gear, viscous, and clutch LSDs all have the same appearance as those from other manufactures. I would bet that if Nissan can't find clutch plates, a Subaru dealer can, as they still use the R160, and R180 in many of their cars. 2 Quote Link to comment
Stoffregen Motorsports Posted October 27, 2017 Report Share Posted October 27, 2017 One simple trick to gain breakaway pressure is to flop all of the concave discs upside down and clamp the unit back together. I don't know why this works, but it does. It has something to do with the contact patch of the spring discs. Getting the unit back together without problems is tricky after you flop the discs as now the last couple discs are not located in the main housing and can turn while the cap is being tightened down. It's hard to explain, but once you've got it apart, you'll see what I mean. One piece of advice: before you disassemble the unit, stake the two halves so that they go back together in the same place. If the carrier is warped even minutely, and the phasing isn't the same going together as before it was taken apart, it can cause runout. Also, be sure to check for burrs inside the clutch housing and smooth everything out while you have it apart. Clutches hang up inside if there are burrs or ridges. Quote Link to comment
Stoffregen Motorsports Posted October 27, 2017 Report Share Posted October 27, 2017 And if you're really brave, you can machine a few thousandths out of one side of the unit while it's apart. This will lessen the distance between the clutch contact surfaces making all the clutches tighter. I used to do this, but that was back when replacement parts were available and these units were not so scarce. Quote Link to comment
Icehouse Posted October 27, 2017 Author Report Share Posted October 27, 2017 Thanks guys! I'll post some pics of the bad one popped open. So annoying do all the work to get a H165 into a 71 510 just to use the LSD then have it not work.... Quote Link to comment
G-Duax Posted October 27, 2017 Report Share Posted October 27, 2017 Wait, you have an H165 in a 510 ? Thought the wagons all had H190s, and non-wagons had R160s. Quote Link to comment
datzenmike Posted October 27, 2017 Report Share Posted October 27, 2017 In N Am they did. Mexican 510s may have had J13/15s? They might. Quote Link to comment

Icehouse Posted October 27, 2017 Author Report Share Posted October 27, 2017 As they say, the grass is always greener......... To be fair we were on the hunt for a H190 LSD. Basically any amount of work is worth it to have an LSD. 1 Quote Link to comment
afracer Posted October 28, 2017 Report Share Posted October 28, 2017 I have an H190 LSD for sale Quote Link to comment
G-Duax Posted October 28, 2017 Report Share Posted October 28, 2017 Wrong spline count for the wagon, they have 27 spline axles. Quote Link to comment
datzenmike Posted October 28, 2017 Report Share Posted October 28, 2017 Truck are all 29 spline, except earlier L320? that were 13 tooth. Cars, including 810/Maxima wagon with the H190 are (usually) 23 spline with the exception of the '81-'82 S110 200sx and the '84 S12 200sx that both had the H-190 differential and were 29 spline same as trucks. 29 spline 23 spline 13 spline Quote Link to comment
G-Duax Posted October 28, 2017 Report Share Posted October 28, 2017 The Japanese market 5-lug Gloria & Cedric were 29 spline. My H190 came from one of them, along with my 4.62 gear set. Quote Link to comment
datzenmike Posted October 28, 2017 Report Share Posted October 28, 2017 The '73 L16 automatic 620 and '80 720 long bed automatic got the 4.625 H-190. Pretty rare. Z24i powered Pathfinders did too but have never seen one, all were C200 diff anyway. Quote Link to comment

hang_510 Posted November 25, 2017 Report Share Posted November 25, 2017 None of the larger Nismo LSDs I've had ever had anything stamped on them. a Subaru dealer can, as they still use the R160, and R180 in many of their cars. All the LSD I had was stamped with something. No markings on mine, out of a Nissan box. Quote Link to comment
