Diff Ratio change, 4.875 to 5.29 (& now a 5.86)From what cars can crown and pinions be used?
I have read the greeks are swapping in 4.875 gears, not sure what from? Pinin on the rocks?
These are available in gen1 Pajeros, so i assume they would fit, the ARB airlocker is the same for both gen1 pajero and pajero IO... anyway, the gen 1 2.3TD came with both 4.875 and a 5.29. So im hoping the 5.29 will fit our iOs! Depending on price i might just bite the bullet and try.
Mine is also 4.875
Sorry, yes, Mine is also 4.875, just had a look, infact i knew that
Seems the greeks had a lower ratio than we did?
either way, just did some digging. I counted the spline and diameter on my front kaiser locker i have sitting here and its the same as a gen 1 pajero. so fingers crossed the crown and pinion will work too!
Axle Data
Gen 1
2.6, 2.3TD, 2.5TD & 2.5TDI (some) :-
front axle = 25 spline, 29mm diameter, diff = 7.25" diameter (low pinion)
front axle = 28 spline, 29mm diameter, diff = 7.25" diameter (low pinion from an L300)
rear axle = 28 spline, 30.5mm diameter, diff = 8" diameter
3.0V6 :-
front axle = 28 spline, 29mm diameter, diff = 8" diameter (low pinion)
rear axle = 28 spline, 30.5mm diameter, diff = 9" diameter
Diff ratio and T/case & Final Drive Ratio's
Gen 1
2.3 TD = 4.875, 5.29
2.6 / 2.5 TD = 4.625, 4.875
2.5 TDI = 4.625, 4.875
3.0 V6 = 4.625, 4.875
t/case = 1.944:1 low range for 2.6, 2.3 TD & 2.5 TD, 1.925:1 for 3.0 V6
The 4,875 swap was from Pinin
The 4,875 swap was from Pinin 1.8GDi model manual. Have in mind that manual and auto models have different type of diffs even with the same ratio. The shafts in the auto models are smaller. Just by having the same ration it doesn;t man that it is the same ring and pinion. For example the 4,636 ratio u can find in 2.0 and in 1.8 old models both have the same ratio but different Mitsubishi part numbers, which means that have different dimensions.
Shaft diamteter and spline do not matter since it is the differentials' dimensions and since u keep the same diff they willl stay the same. It is the number of bolts and internal and external diameter of the ring that changes and is very important to check if it fits in the diff case and into the differential. Also the pinions are different and in order to fit in the same diff case it''s quite rare and difficult.
The pinin's diff for the 2.0 manual models are:
Front: shaft diameter 26,6 splines 25 bolts 10 ring int diam. 112
Rear shaft diameter 30 splines 28 bolts 10 ring int diam. 124
For example almost all pinin auto models on the front they have 8 ring bolts.
Even if the diffs are the same with some pajero models, i find it almost impossible for the ring and pinion to match 
Spot on, good info too
Spot on, good info too POR!
Sometimes most do things that amaze and excite me however. The rear crown and pinion from the gen1 pajero and the late model stations are interchangeable, (i have done it) and the front gen1 crown and pinion will swap into the older stations. (I'm told)
I'm not holding my breath the fronts will swap into the io tho. But fingers crossed.
Interesting that the sizes are different in different pinyin models. Kaiser claim there lockers will fit in all fronts from memory?
Now you have me worried...
By the way, i have kaiser
By the way, i have kaiser lockers front and rear for 2 years now so i can inform you on the change of behaviour yr car will have (not all to the best)-especially if u have manual transmision) u can see more info here http://www.d-90.com/forum/showthread.php?t=25328&page=11
Do u have the file with the kaiser lockers dimensions for all the pajeros? i can share it if u want
Kaiser "claims" lockers will fiτ in all fronts on the TR4 model and the ones that are produced in Brasil, that doesn;t mean it;'s the same with all pinin's and IO's around the world, i remember when ordering mine that it's not sure it will fit because they had occasions that not all front pinin diffs are the same, and i had to check the dimensions and bearings before ordering to make sure it fits...
By the way, having seen both diffs front and rear, i doubt there might be any other rear that will fit the front and vice versa, they have big differences in size...
What model is yr car?
Diff data
OK, main difference from all
OK, main difference from all my measuring seems to only be high pinion vs low pinion on the front diffs..
All the Gen1 diffs are low pinion. meaning they will not work in the iO / pinin front as the iO is a high pinion.
The gen 2 diffs are all high pinion, look like they could be retro fit reasonably easy, but they are almost all 8" diffs with a different spline , BUT, even better and easier, the gen2 3lt V6 auto has a 7.25" front diff, and Mitsubishi sell a 5.29:1 to suit them. SO im 95% hopeful that these crown and pinions will fit the pajero iO!
If not ill just retro fit the entire diff housing in order to run them.
After digging through the
After digging through the parts in the link fordem posted it seems the front and rear pinion bearings are the same in both 1999 iO and gen1 3ltr v6 auto, So thats one step closer to not ruling out a 5.29 ratio :)

It was interesting to note the 98 and 2000> share the same front "gearkit/diff case" whatever that actualy is?, but the 99 had a different part number. Seems only the 99 iO has the same bearings as the gen2 pajero.
EDIT: It also shows the carrier assy, fr diff as been diferent to what I actualy have in my iO. and only the 98 having the 4.875, clearly not true for us in Australia. So

I have read on the pajero forums that guys may be swapping the 8" front diffs into there 7.25" housings, so they can run lockers. I dont see how the pinion can fit, so im not sure its accurate. They probably swap the entire housing and front shaft.
OK guys, Now im exited! The
OK guys, Now im exited! The 4.875 pinion from the 3ltr V6 auto pajero is the same part number as the 4.874 iO pinion!
This means the 5.29 Pajero option ratios for the gen2 pajero (V6 Auto 3ltr) will fit the iO !.... Well, the iOs with the 4.875. According to the listings thast late 98 and 99. Im not realy sure how different the others are inside?

The crown wheels are a different part number however, I think the iO / pinin is a 10 bolt but the gen2 pajero is a 12 bolt.?
A pain in the bum, but nothing we cant work around :) Id say Kaiser will drill me one with 12 holes instead of 10 if i need.
Looks like the 96 - 99 triton came with them,, atleast it some countries? http://mitsubishi.epc-data.com/strada/k74t/gjerxf/front-axle/front-axle-differential/1710/

Thats the plan :)... Ill make it work!
the old Pajeros (gen1) have 10bolt rear too.
Im not 100% on the ratios, I think the 2.3TD rear may be a genuie 5.29, but the gen2 front is actualy a 5.285.
0.05 difference, so close i do not think it will matter!
EDIT: Just noticed the Strada and iO share the same pinion (same part #) but the strada is claimed to be a 5.285 ratio! so sometings gotta be off there?
Thanks jop! Looks like they
Thanks jop! Might have to make a place in here for jtops too! All baby pajeros :) Looks like they are all 5.29 too :) and a gear kit part # I have not seen in anything else. Intersting ! You sure they are 7.25"? And high pinion?
I think I'm going to have to get one!
Maybe I should have mentioned ...
It seems those parts lists may be for the JDM Mitsubishis only (although I notice that the sections for other Marques are being expanded) - and I have learned the hard way, that parts used on JDM vehicles may differ from those used on export models, which may also differ depending on the market they were built for.
One of the things you can do is enter your chassis number in the search box - if the site returns the correct description for your vehicle, which will include the date of manufacture, the numbers will be valid for your vehicle.
5.285 Diff ratios ordered !
Nice one JOP! how has it been for you, manage to bust anything off road yet? what mods is it running? Push button lift would be nice!
I have just bought a front and rear diff with 5.285 ratio in them from Bogger on the Vic pajero forums ( A1 Pajero parts on ebay ) great bloke!
Will soon see if the front crown and pinion swap over!, fingers crossed,, IF not ill swap the entire housing if I can. If i swap the entire housing i wander if i might as well just go to the 8" front, I dont think the 7.25" crown and pinion is the weak link though, CVs im guessing, If i bust them to often ill have to find an upgrade.
It's been great so far, it
It's been great so far, it has:

Still to come - front locker, 33" tyres, snorkel and boost & fuel increase
Awesome news on the gears, can i ask the price?
I want to see if the local wrecker is correct in his pricing, pretty sure bogger knows the paj market.
5.285
SOrry JOP, was $320 delivered for front and rear. BUT he made a mistake, THe rear was a 9" and the front was a 4.875, turns out someone swaped the ratio, I could see silicon used when it was put back together at some point :( It was originaly 5.285
SO i still need those gears if you can PLeeeease help me! Im about to rin every wrecker in australia looking for them..
I have dug even deaper, Looks like there were 2 lart numbers for 8" 5.285 crown and pinion gear sets, and this is realy interesting, The iO 4.875 rear gear set is MB527147, and the 5.285 is
MB527149! now replaced with the above mentioned MB241981. But it looks like there atleast available in japan, so if i must i will import one.
This is the data for a delica star wagon. As you can see, getting a 5.285 in the rear will be no problem for us. Just need to sus out the front.

All Jtops have 9" rear diffs. (have one sitting here, wona swap for a 7.25" front? :)
Andcthe Jtops has 2 version of front crown and pinion pary numbers. Both 7.25" and both 5.285 ratio. Not sure what the go is there? Are they interchangable? Id assume so. But its still weird.
Can never have to many pics!
Can never have to many pics! Ill have to start taking more!
What is the center on that, stock? I thought it was a kaiser at first, but they dont have holes in them...

Good find, looks like the chinese gears are risky, I may ask them for a sample to test first, due to the problems others have had in the past....
I just had a look at the 9" i have here, and yes its a 12 bolt.
But the 7.25" are also 10 bolt, atleat on the Kaiser center i have and from meory also on the other pajero front i have sitting here.
5.285
I have been checking a French pajero forum and I found that one gen 2 pajero have a 5.285 ratio, 2.5L TDI engine LWB

Yeah im trying my luck at
Yeah, If i manage to sell em ill order another one and spend extra having a front custom made. there some places in australia that will do it. I have read of a place in NSW that make em for $450, but they only last 30k, ill ring and find out. maybe due to lack of heat treatment after machining?Out warehouse is next door to hear treatment plant, im sure i can get them to do something for me for a reasonable price,?
So to fill in everyone else. I got a pair or 5.86 gears, and foolishly didnt think about the fact the front may be a low pinion for a gen 1 pajero, (until after i ordered) and it was! The rear does fit, but the front will not as as the io is a high pinion.. and no one makes a 5.86 high pinion front. so its a custom front or a 5.28.
You have three options...

My first post here...and I feel bad seeing this...
Pajero Gen.1 and Galloper's front diffs are low pinion so there is no way this to fit in the front of your pinin.
You have three options...
A. Keep your 7.25" front hi pinion diff (or find one if you do not have this) and go with the 5.29 gears. Not very close to 5.86 but it is your best alternative.
B. Try to see if you can fit an 8" low pinion front diff in the front of your pinin.It must go together with the side tube-axle housing. If it is possible then we can discuss it in details...
C. Make your own gears. Be very carefull because in many cases it is a waist of money (and time).
Cheers.
George.
Yep. 5.28 it will have to be.
Yep. 5.28 it will have to be. Still good I guess. 5.86 would have been awesome. I have had a look and the low pinion housing will not fit in the io .
Still tempted to make my own gears. Next time I go to China I will visit some places and thoroughly check there QC and manufacturing proccess. Problem is we need minimum order of 300 units for a custom set. Total cost will be $4000. A good price for 300 units. And I guess worth doing if there were 10 of us interested...?
Infact I will order a rear 5.29 from them to test...
China...?!
China...?!...I had bad experience with them !!!
For gears see also here... www.kamdiffs.com
By the way, what diameter is the 5.86 gears you have ?
Like everywhere in the world
Like everywhere in the world china makes good and bad products. We have all our product made there and they are the best in the world. BUT we did a lot of work to find the right places! some was RUBBISH!
They are 8" rear and 7.25" front..
Apparently these guys can make gears too http://www.cutandgrindgears.com/contact.html
Locker comparability
Here is the confusion.
It seems Brazil ran the 3ltr Pajero with a 7.25 and 8" fronts. As you can see the 7" version for the 1997 pajero is the same locker,
as for the io / pinin (KL103)
I just went over the 7.25" pajero front I have here and its defiantly compatible. So worst case Ill just swap in the front in order to run the 5.29 gears. It will mean making and welding on some new flanges, but all other dimensions are the same and it will bolt right in.
Syndicate
diff ratio
While we are talking diff and ratio, I am going to take my car to ARB for them to try to fit a front diff locker, any info on the front diff...spline, match other car, ...that could help them sorting thing out. I haven't booked yet, but it is on my list.
I bought a spare transfer case on the net, just got it...I will play with it...when I get time...
