Sm465/NP205...10 to 32 spline

[Davethorik]

I have been thinking about converting my current combo 465/205 so that the 465 has the 32 spline output and the 205 has corresponding 32 spline input. reason being i took the combo out of my truck and the tranny output is almost stripped, and the drive sleeve is the same way. it would be easiest to just swap a complete 465/205 out of a newer K30, but...kinda hard to find. i would like to eliminate the drive sleeve if at all possible to eliminate driveline slop also.

on ORD's website, you can order the 32 spline conversion kit for the 10 spline NP205 for $200 (includes female input gear, bearing, and gasket/seals). It says machine work is needed on the case. this is no biggie.

my question is, can i use the conversion kit on the NP205, and then buy a new long 32 spline output for my 465 and use it with the existing adapter to mate the two? Both have figure 8 mounting patterns. the adapter is the long one that the drive sleeve fits into on all early 465/205 combos.

if not, would there be any economically feasible way to convert my existing junk to 32 spline? If my adapter would not work, would there be any cheap alternative for this, or am I just dreaming?

Oh, and I did search...90% of what I found relates to LC's.

Thanks, and sorry for the length.

first a question
did you have gaskets between the boxes and adapter?

ORD also sells a custom 32 spline sm465 mainshaft that may work for you, call them and get the overall length of it

[Davethorik]

yes, there were gaskets in between the transmission/adapter and adapter/transfer case. there werent any bearings in the adapter, just the sleeve.

i was kind of wanting to steer clear of custom parts, that was why I was wondering if the stock 32 spline output and female input would work with the 10 spline coupler.

[mj]

do you have the 32spline mainshaft?
they arent the easiest items to find
as you are already talking about buying the aftermarket 32 spline input that ORD sells (available cheaper elsewhere) I didnt think you minded aftermarket stuff
I was quoted abour $240 for the mainshaft
I havent looked for it elsewhere yet

[Davethorik]

Ouch...I dont mind using non-ORD stuff that is cheaper, I just used their site for reference. Right now I only have the wiped 10 spl mainshaft. I just dont want to keep replacing these stupid sleeves and mainshafts, which is why I thought of using 32 spline..which would also be stronger and eliminate some drivetrain slop also. I guess it would be cheaper to locate a whole 465/205 combo out of an 85 or newer K30. Or just get a new 10 spl mainshaft and sleeve.

[mj]

I think the overall length starts getting up there with the OEM 32spline stuff

[Davethorik]

Yes, I was pm'd a link to a pic of a stock 465 with the 32 spline shaft, and its long. I was just wondering if it could be made to work with my stock 205 adapter. I guess I should find out some measurements, such as length of 32 spline shaft plus 1.25" that the TH400 32 spl input gear sticks out, and then measure my 205 adapter. It does look too long still, which sucks. Could the stock mainshaft be cut to length?

[Davethorik]

i also found this site,
http://www.drivetrain.com/muncieSM465.html
towards the bottom they have "Main Shaft 32 Spline" for $125.
hmm

EDIT:
also found at Novak for $123.90
it states that the 32 spline version is 19.63" (long?)

the 10 spline is 13.75"

[mj]

10 spline couplers have 1.3" of spline engagement as well as an unused area between the snap rings
I have a coupler or 2 here I can measure but no 32spline inputs to use
the measure ment you need is the distance from the face of the 205 to the tip of the splines

[mj]

overall length of 10spline coupler 4.25"
6.75" for a 10 spline adapter

[Davethorik]

According to ORD's website, the short 32 spline gear sticks out of the 205 by 1.5"
the long 32 spline gear sticks out 3.5"

[u2slow]

Is the early SM465/NP205 adapter the same length as the SM465/NP208 adapter?

EDIT: I dragged my lazy ass out my garage and measured the SM465/208 adapter. 8.5" long.

Now one of you fawkers can go out and measure the other one

[49willys]

The 10 spline 465/205 adapter is 6 7/8" long

[Davethorik]

does the NP208 adapter use a figure 8 or circle bolt pattern? If it would bolt up to the NP205, then that would be the hot ticket. I assume all 465/208 combos are 32 spl?

[mj]

208 is circle if you are talking TC pattern
IIRC only the 205 uses a fig 8 and then late ones were circle as well
the rear face of the 465 didnt change as far as I know
ask 'u2slow' for the details on that stuff, he knows it cold and has images to back it up

[Davethorik]

damn, I was hoping that the early 208's would have a figure 8 pattern.

i found another post, and Steven from ORD says that they sell a spacer that bolts to the stock 10 spl 465/205 adapter to allow use of the 32 spl long mainshaft. that would probably work best, I wonder if it matters what side of the adaptor you bolt it to. thanks for all the help so far, guys.

[mj]

the adapter faces are different pattern
you wish it was that easy
ORD has that shaft I was mentioning earlier
apparently it is splined the whole length, from bearing out, for cutting down to different applications
you just need to determine the length required
also remember there are 2 32 spline 205 inputs, long and short
