LSD Install: Cusco MZ 2way

[Bubble_Drift]

I ordered my LSD through Speed Industries.
Very good service and fast delivery!
Also got 3 liters of Valvoline 80w90 GL-5 LS oil. (diff capacity is 1,3L)


These are the tools I used.
Numbers 12 for the diff casing and 14 for the brake callipers and half shafts.
And 24 for the fill plugs.


Jack car:


Drain the oil:


Remove wheels, brake calipers and brake disks. Then undo 4 bolts that hold the halfshafts and pull them out.


On one side I had to use a special tool because I couldn't pull the halfshaft out that easily.


Then unbolt the driveshaft and the +/- 10 screws around the diff and pull the diff out. (watch out it's quite heavy)



Here is the rear axle empty. You can look through it.


Here is the diff casing, halfshaft and Cusco lsd.


Here is the old lsd out of the casing:



The bearings on each side of the old lsd are difficult to take off.
I just bought a new set. 2x LM501349 and 2xLM501310

Next step is to take the ring of the old lsd and put it on the new one.
First unbolt the 8 screws on top. And then tap it out.

Then you have to heat up the ring so that it expands a bit to slip over the new lsd. Do not heat the ring over 130 celsius. (says the manual)

The lock plates that hold the bolt on the old diff, don't fit the cusco diff.
I just used some loctite on the bolts instead. Torque to 96 N-m.

No comes the tricky part. Putting the new lsd with ring back in. The important thing is to adjust it just right that the ring and pinion are straight on each other. Because I didn't have the measuring equipment nor the professional experience I brought the diff to Toyota. They worked on it for 1,5 hours and charged me 100euro!!! But they did a good job.

Here is the diff as I got it back from Toyota:


I used some liquid gasket around the diff and put everything back together. Easy jod:


Fill it up to the fill plug and you're done!

Silly pic I took. R33 17inch rim for measure


Oh yeah. After installing you should break the new LSD in.
Drive 8 figures for half an hour...not much fun I can tell you...haha.

I still have to change the oil after the brake in.
Doing it tomorrow. And then I'm finally done

OK now how does it drive.
First off...I was very carefull the whole time.
When driving very slow and letting the clutch go slowly, you hardly notice any difference. No noise or anything. I was quite happy about that because I read on several forums that aggressive LSD's as the Cusco MZ are noisy as hell. (Cusco RS is supposed to be more quite/softer)
But when giving a bit more throttle in slow turns/ roundabout you start hearing and feeling the LSD pushing the car to one side/ locking the wheels.

Al in al I'm very happy with it!!

great post

driving a figure of 8 for 30mins doesn't sound like much fun though.

Hehe, I can just picture it, doing figure 8s on the parking lot,

police comes by

What are you doing sir??

Owh, just braking in some new parts I just installed on my car, sais right here in the manual....

lol

Glad to hear you managed. Also glad you took my advise and had a shop properly adjust the R&P

owh and the 17"s are so wrong for a hachi

Great write up ..


So you can pull out the halfshaft without using "slide hammer" !?

What do we see here? Right... a slide hammer

It all depends on how tightly the axles are mounted.. once you've taken them out a short time ago and reassemble without any locktite or other crap, you can usually pull them straight out by hand. Otherwise banging the flange from the rear using a block of wood as a buffer has helped me before. One of nohachi's axles required the assistance of my little butane burner to get it loose.

So I have driven the car with the new lsd for a couple of days.
It does make scary noises!! But it only happened at the MC Drive were you have to ride in a tight lane at 5km/h.

Driving it in the rain is fun especially on roundabouts. But also very controllable if you don't drive like an idiot.

I thought the RS was the noisey one and the MZ was for street?

[Bubble_Drift]

No it's the other way around. "With the Type RS, the initial torque is absorbed by the RS springs therefore the initial torque comes on gently compared to the Type MZ which comes on stronger as it uses cone plates and response of the LSD is better, as the friction is lower"
