MQ transfer/box/diff serial numbers

[Screwy]

guys,

ive been continuosly hearing about all these types of gearboxes and Diffs for MQ's.
curious about something.....

WHERE DO YA FIND THESE NUMBERS!?!?!?!?!

for instant, the transfer case numbers: T130A and T100L.
where are these numbers located so i can see wat mine are.

also the diff numbers like H233 and crap...

THESE NUMBERS HAVE BEEN DRIVING ME INSANE, and its embarising that i dont know where they are?!?!?!?!

Transfer case is easy, if it is bolted to the back of the gearbox like most are, it is a T130L. If it is separate it is a T100L.

thanks dave, well that answers that little part.
Now i just need to be able to tell which diffs i have so i can get a locker

[beefie]

front will be c200 rear will be h233b. and there is a h260 rear HUGE.
I have been misslead on this one before but once you see one you will know the diffrence.

The axle designations describe the style (banjo/drop-out/third-member/Hotchkiss vs. the one-piece Salisbury type w/ removeable cover), and the size of the ring gear in millimeters.

The C-designation axles are the Salisbury type. About all I'm aware of are the C216 used in the 1960's-era Patrol, and the C200, which has been used in all kinds of applications including the Y60 and MQ Patrol (also as a front axle), and on any number of small pickup/SUV applications, RWD vans, and even some medium-duty trucks.

The H-designation axles are the Hotchkiss type with the removeable third-member/carrier. Ranging from the little H165 used in some older RWD cars and vans, the H190 used in the Roadster/200SX and light-duty pickups and vans, the ubiquitous H233 used in the rear all sorts of pickups, SUVs (also as a front axle on the Patrol), and even large cargo trucks (there was a full-float dual-tire 1-ton version), the large H260 used in the rear of some Patrols and many cargo trucks, and the massive H290 used in 2+ ton cargo trucks.

There are also rear axle codes that describe the type of axle and approximate the gear ratio. For instance, the HG46 axle is an H-type, G designates the H233, and 46 indicates an approximate 4.6x ratio. See the link at the end for more on that.

Then of course there are the R-designation, which are the independent-suspension types from Hitachi. All are Salisbury-type with cover plates. The were used in the rear (R160, R180, R200, and R230) in scores of RWD and AWD applications. There are also front-end versions for 4WD IFS trucks/SUVs including the R180 and R200A. Subaru has also used the R160 and R180 for some time, the smaller Imprezza/WRX has R160, the STi has R180 used in the larger Subarus (Liberty/Outback).

Many of the internals of the same-size C-type and R-type differentials can be interchanged with minor accomodation.

Transfer cases, in addition to the older ones mentioned above, there are the following married transfer cases
TX10A: part-time, used in Pathfinder (1st-gen/WD21 and 2nd-gen/R50), Navara (D22), and pickup (D21).
TX12A: part-time, used in the Patrol/Safari. I'm not sure if the offset one used in the MQ is a TX12 variant or not.

ATX14A: full-time, used in the R50 Pathfinder.

That's about all I have for now. There's a good recent FAQ for USA axle applications here that would be worth looking at too:

impressive Brent....I feel like I just took a class on Nissan drivetrain.

Seriously though, good info. All that realy matters to me is Patrol stuff but good info none the less.

All I have to add is this....
The C200 did come in the rear but I don't think it came on Patrols in Australia. The H260 has been around a long time, since the 1960's. All G60 Utes or "H" models like a G60H have the H260 older version which is offset. The C216 is old from the G60's and is called a light duty axle, it only came open and nobody has ever made anything for it off the shelf such as a Detroit or ARB locker. The C216 is very similar tot he C200 in that it is the non-3rd member type. The old H260 should except a Detroit locker but I am not sure what Detroit. I have seen C200, H233B and H260 all in both offset and center. The G61 series of Patrol that is very rare was fitted with a version of the C200's front and rear and also a H233B or H260 in the back. These are the same as the MQ diffs except they mount different, they mount more like the old G60 diffs in terms of their perches, shock mounts and so forth. The G61 also has a version of the 4spd and transfer that mounts a bit different. You guys only got about 400 G61's in 1980 so no need to worry about those....yet, in some countries the G61 was sold up to 1983. This is why the early 1980's Nissan manuals have the G61 and the 160 in the same books.

To me the G61 is one of the coolest version of the Patrol ever made in over 50 years. See my avatar for my 1980 G61

Oh yea, and....I got a UK version brochure for the MQ recently. It states ALL European MQ's got a rear LSD no matter what diff it had. So this confirms Bart's statements on this subject recently. To USA guys after Patrol diffs this could be a bit of usefull info....

And I also forgot to add....the 4W60 Patrols from the 1950's were fitted with a center rear diff and an offset front. These early diffs are a bit larger than the C200 or C216. It also had a massive 4spd that had no synchros and the transfer case is pretty small in size. Sorry I don't have numbers for the 1950's stuff. I have seen them though. And then don't forget the 1950's 1-2 tonn troop carrier made by Nissan. It also had a 4spd with a super low 1st gear. Like 7.13:1! And lastly, the Indian army has used the G60's for their military jeep since 1967. There was a version of this for the special forces that came with danas and lockers.

Right so the C200 is the type with the front cover like most MQ's have, ive got that down.

with the H233, and the H260........... Is the H260 physically bigger in size to the standard H233?
if so,

Will the H260 fit in the H233 housing? or is it bigger that way also??

the next question would be..... The 4.8's that came out in the later model utes, were they H233 or H260?

cheers guys,

I learned here that the H233b and H260 third-members will interchange physically, but of course only when the axles have the same spline count. I was pretty shocked to learn that H260s were available with 31-spline shafts.

There they say they use the same housing, but I've seen so many references to the H260 being noticeably larger. I've got pics of an H260 somewhere but can't dig 'em up...

[Offroad-Events]

@Brent
If you need axles or housings let me know. Off centre H233's are quite easy to come by here, also C200 LSD's.

[bazzle]

Remember that MQ and GQ etc h233b etc have different crown wheel bolts, lenghts and diamaters also pcd differs. You must specify what the diff is from to get an Air locker etc

the next question would be..... The 4.8's that came out in the later model utes, were they H233 or H260?

Screwy I would be willing to bet they are H260's. The H260 is equal to a Dana 60 in size, axle diameter and so forth. It is rated at either a tonn or tonn and a half axle. It only makes sense it is fitted to utes and since a ute is generally used for work in mines/ranches/farms I would expect it to have the lower ratios. In the old G60's the utes ALL came with a H260, nothing else could be had for them...the "H" models also have the H260, it is simply a heavy duty diff. That is the old ones though and I don't know enough about MQ/MK to say for sure...

Just one more thing to add....while in S.America I learned the H260 is/was fitted to all police specific Patrols. Generally these are all white and LWB. I also crawled under a few Nissan buses and saw some H260's in center pumpkin. If you look at the ARB catalog on their website it shows all Nissan diffs from 1980 onward, axle diameter and spline count...I think ratios too. Maybe that can help you....

[Screwy]

cool, i may just look on the website tonight.

So in saying the centres are a different size, does that mean that if i wanted to fit 4.8, H60 diffs i would have to use the whole housing and axles etc or can i just use the centres and interchange between housings??

cheers,
