I just ordered some 4.33 gears
for my TII

Now i see a bunch of bearings and stuff listed on the mazdatrix site

what should i replace at a minimum when installing new gears

any one?

Lock nut (All)

Pinion seal (turbo)
Front pinion bearing (Turbo)
2 Required

Spacer tube (Turbo)

Middle pinion bearing (Turbo)

Collapsing sleeve/collar (Turbo)
Rear pinion bearing (Turbo & N/T)

Side axle seal (Turbo)
86-92 Turbo side carrier bearing

 

every thing and you wont have any problems for a long long long *** time!

 

prussian blue dye? dont forget the small stuff.

 

Seals and bearings, as with anything else.
Don't need the crush tube or spacer.

Some bearings may not need replacing after inspection but that is a judgement call on your part.

 

FSM recommends replacing the collapsable collar.

 

yeah, it says it MUST be replaced if its removed, basically everything in there should be replaced, including clutch discs if you have a clutch type lsd wich was standard on all s4 t2's i believe.

 

Your right, it does.
Hope I didn't shoot myself in the foot.
Can't see the need to replace it though....

 

I have never done one of these and am not entirely sure how it functions. What I do know is that it deforms when torqued down, along the lines of a crush washer, but without the sealing capacity. It is supposedly a one time use item and may not perform it's full function a second time.

Sorry about your foot.

 

Well it's survived 3+ years and several dozen track events so I'm not to worried.
