i have a trans stamped as follows can't figure this one out AH 30 33 891 ???????


i can figure out ones stamped like this AT 02 03 6 produced 2nd of march 1976

[Bruce2]

The numbers after the AH are just a meaningless serial number. They dropped the counter serial number in favour of the date serial number in late 1972. Thus, your AH was made before then.

Thanks a bunch Bruce the AH is a double side cover case so i am having the AT built into a maxflyer 3.88 0.89 4th super diff and the good weddle reinforced side that should stand up behind my bunny motor for a while and drop my hiway cruise RPM just a bit

i want to try the royal purple gear oils any input???????

and yes Bruce its still snowing here in ontario supposed to get 5 cms Saturday my daughter is headed for BC next week

[2088bob]

AH should have small diameter cross shaft AT should larger diameter cross shaft correct

Snow! People are starting to open the windows in the transit trains here.


I have one AH SSC gearbox with the large cross shaft, so you can't say all AH have the small shaft. Also, I have had DSC AT gearboxes with the big shaft.

To date a gearbox with only numbers and no letters in the code, go here:

Yep, code is AW. Same spec as above.

Is there a thing trans that came with an OE 4 spider diff??

No.There was a plate type LSD or the more common 2 spider style. 4 spider diffs were made by a few aftermarket places with random reviews.

No.There was a plate type LSD or the more common 2 spider style.

The factory installed ZF LSD has 4 spider gears.

Just checked the numbers on my trike and they are AH 4659. Everything I find says it's a IRS, but it's a swing axle. Any thoughts?

[Bruce2]

It is an IRS gearbox that has been converted to swing axle.
