New nitro diff gears and solid pinion spacer.

[Lowisuzu]

after recently ordering a set of 4.88's and solid pinion spacer, i have just start pulling the diff down and put the new and old pinions side by side.
The solid spacer seems to be a heap shorter then the original crush tube...
Does this look correct?

[Ice]

there should be shims with it to set the preload

[AngryElmo]

i looks like it mif=ght be short but it has to be shimed up as pre mentioned. with mine they solid specers where way to long and had to be trimed up. it is possible they have sent the wrong one, but im sure a phone call to ask them should solve this problem. they are very helpful.

that pinion looks way too big for the car in the background.

[Lowisuzu]

Yes, i think i will have to ring and inquire.
the spacer came with a set of shims, but nowhere near enough to make it the same size as the crush tube...
ugh...

[Lowisuzu]

so i just double checked the difference between the two.

the crush sleeve is approx 60mm
the solid spacer isnt even 50mm including all the shims...

Any Help?

how much does the crush tube compress when your doing it up?

I wouldnt have thaught it would be 10mm, but perhaps it is?

[Lowisuzu]

well, the crush tube is the old one, so it is crushed... does the tube "un-crush" when pressure is removed from it???

[Modified Toy]

Nope the crush tube doe not uncrush what is you origional raito?i thought you could not fit 4.88 in a standard housing being that the crown wheel needs to move over further, correct me if i am wrong.

Did you order off locktup? maybe give them a ring, they are very helpful and will know.

You can fit different ratios in the same housing, however i believe you cannot fit 4cyl gears into a V6 housing and vice versa.

I have just ordered the exact same thing from locktup, so let me know what you end up finding- they are very helpful.

i was under the impression there was only drama's fitting the gears in the older housings, which needed a different bearing installed.

i have Chris from locktup chasing this up for me at the moment.

Original ratio. not 100% sure, but when i jumped under the truck and spun the tailshaft, i got about 3.5 revolutions to 1 revolution of the wheel. so i dunno if its a 3.5:1 or something similar to that...

[Lowisuzu]

Hopefully get that pinion bearing off tomorrow and put it on the new pinion to mock it up and see if it all fits and if i can set the pre-load correctly.

would i be correct in saying that the pinion having 10 teeth and the crown having 43 makes it a 4.3:1 ratio diff?

took another couple pics.

Yeh thats correct.

What did chris say from locktup bout the spacer and gears?

[Lowisuzu]

We spoke for a while last night and came to the conclusion that we still dont know exactly whats going on.
I have the right spacer, the right gears, and what appears to be the right housing, but it just doesnt appear right.
i am going to mock it all up, see if i can set preload ok and that it all seems fine and get back to him after that.

i havnt been able to get the bearing puller i had hoped to originally to pull my pinion bearing off. i should be able to track one down. are there any backyard tricks to getting the bearing off without munching it?

Nah just the bearing splitter and a large 2 jaw puller and it should wind off

Then heat the bearing up in the oven and just drop it on.

[Lowisuzu]

so got the pinion bearing off as i had to buy a new bearing splitter.
But for the life of me, i am unable to get the pinion seal out.
i have read on here AND in the Haynes manual that it is easy to pull out. but it is just jammed. Cant get it out.

Any help?

[brad 93hilux]

You can get a seal puller from ebay or any auto shop which makes it alot easier, or just be persistant with a flat screw driver and you will eventually pry it out. It get destroyed when it comes out and they are usually really tight..

Good luck

Like that

[Lowisuzu]

So finally got the pinion seal off. took a big F-Off screw driver and a pole to extend it to pry the sucker out. man it was stuck in there hard.
got the inner pinion bearing in the oven atm so i can put it on the new pinion.

[84sloth]

man that seal must have been in there a while coz usually a big screwdriver and a good hit with ya hand usually sends them flying.

[Lowisuzu]

ok, so Chris and i may have sorted this problem out.

i have another set of spacers on the way, this time... the right ones. lol

hopefully these turn up tomorrow and i will be putting the diff back together over the weekend, so i will be able to confirm
exactly what the problem / solution is.

Cheers.

are there any backyard tricks to getting the bearing off without munching it?
