Primary drive sleeve

[Myyke]

Hi folks,
Anyone happen to know the outer diameter for the needle bearing sleeve on the primary drive?

I found the bearing & seals i need, but i need to build a sleeve.

Thanks in advance.

So here is the info i’ve been able to find.

In the 1963-80 gas manual:
Sec 4 pg 4, figure 4b-43. #20a needle bearing, late 64( looking for the sleeve on the outside)

In the 1963-81 gs parts book i have:
Page 9, part 29 in pic,
Part#’s are:
36462-64 needle bearing sleeve assembly (64 to 66)
36462-67 (67 to present)

If i could find just the outside sleeve dimensions or drawing i could build my own.

the 36462-64 sleeve is:
.78" L
1.5" OD
1.368 ID (difficult for me to measure, so your bearing OD should dictate)
In case you don't have an old one, I'll note that this sleeve captures the bearing between two oil seals.
Good Luck!

Exactly what i was looking for. Thank you very much.
Looks like the seals are backwards to what i usually see on other things. Wasn’t sure which way they went in.
Thanks again.

Here is what i was able to find for bearings & seals according to the inner race i had.
Seal: National brand pt# 340815
Bearing: BA188Z

Thanks for posting the cross refs.
The seal on the opposite side is ALSO inserted opposite, so both seals face in the same direction.

I like sharing any updated info i can find, if it help others.

Update: was measuring up parts last night, i found i have to change sleeve dimensions to a different size.

New outer sleeve size with seals i was able to find:
1.00” wide
1.368” I.D.
1.55” O.D. same diameter as Primary Floating sleeve (one with felt). 340815 seal is 1.5”
1.03” Original primary inner sleeve
Once i build one i’ll post a pic.
