I picked this one up amongst a ute load of stuff the other day. It has the obvious mini spool, but I cant see a ratio stamped on it.  Do the other numbers mean anything??

Not yet Clay.  Troy has got me thinking though. I reckon I can see a Toyota symbol next to the 35. Also, if you look at the top picture, the shaft on the pinion gear is longer than normal.

[UCSLE]

I think you are right about a Toyota symbol . 

 

Searching the net came up with a Toyota Crown ms45/ms55 diff that is 8x35 and it looks to be a Holden banjo

 

I,m guessing the 8 is the pinion teeth and the 35 is the crown wheel teeth ?

Teeth 8x35 = crown / pinion = 4.375:1

Local Toyota Crowns had banjo centres but F@4D wheel stud pattern.

If I get time today I will dig it back out and count teeth and splines.

31 spline be nice Laurie,

 & the 4.375:1 ratio @ 4000rpm with 2 metre rear wheel tread circumference would be 109Kph in 4th.

If I get time today I will dig it back out and count teeth and splines.

That ratio might have been used in a manual Toyota Crown Utility. The utes often had a lower diff ratio than sedans while the manual trans versions had an overdrive.

I counted the teeth and yes, it is 8-35.  Seems like a very short ratio for any major racetrack in Australia.

4.35/1 ??
Axle buster right there!

1967 Crown shows 4.375 for 3spd manual and auto. 4.111 for 4spd manual.

 

Late 60's Crown is showing 4.375:1, see brochure below:

By 1971 it is showing 4.375 for the 2300 3spd manual, 4.111 for 2600 3spd manual, 2300 4spd manual with 4.111 and 2600 manual 4spd with 3.90:1.

[Dr Terry]

As I said. if you read that fine print, the 3-sp manual had an overdrive.

 

Dr Terry

[yel327]

Those with the overdrive had a 4.875:1 rear axle in that brochure Terry. The standard 3spd manual and auto for that year were 4.375. That's how it looks anyway.

[yel327]

1967 looks like all 3spd manual had overdrive of 0.7:1. Overdrive looks to be gone by the '71 Crown.
