Re: Need a seal NP205

This might help, there’s another link in this thread that might be useful as well.

Re: Need a seal NP205

I suspect it's the same seal a used on the automatics?
There are two different sizes there.
If you post the ID and OD I'll look.

Re: Need a seal NP205

I did a search and did not come up with any thing relevant like you Gents. I did find the AC Delco one but it was out of stock or discontinued.
Accelo I believe they are the same as Auto's. The one pictured is from my auto.
Thanks
Ron

Here's another seal that looks like the one in the other thread.

"The one pictured is from my auto."

I meant when the speedometer is run from the transmission not the transfer case. Sorry, I can't help without measurements.

Re: Need a seal NP205

the shaft of the gear where it will sit in seal(rubber)is 13/32"
the opening for seal to go in is 1/2" (outer diameter of seal).
Or very close to these dimensions.
Thanks again everyone.
Ron

Re: Need a seal NP205

The OD for the above part is .624 or 5/8
The ID is .375 or 3/8.

Some take the .578 OD. seal.
Which is the seal I have a bunch of.
I'll send you a couple on Monday.
No charge.

The link has the seal for #13.99, an insane price. Then add $11 dollars shipping cost to that.

PM your mailing address.
If they are not correct you need the other size.

Re: Need a seal NP205

I might be off a bit on measurement. So they might work.
Thanks

Re: Need a seal NP205

Accelo got the seal today. It was bigger but I got it in ok and put oil in the top side to see if would leak by. Seems to be working good.
Thank You I owe you one.
