Started a new one in this section and also brought the one in 1973-1987 Chevy & GMC message board back to the top from last month.
Thanks for any help and I will try to get pics this weekend.

That's my next project since I also have the T221. Ready for it to byebye after I get new gears the rear and front end. Good details, right on the money

Are there supposed to be any o rings or seals on the speedometer output shaft and retaining nut?

My 72 case was leaking bad out of the speedo cable and when I removed the nut and shaft there were remnants of two rubber o rings. PO intall or factory? Part numbers or o ring sizes?

Thanks

This looks like an excellent guide to rebuilding your NP205. The only thing I might do differently is, wait till you get the entire thing back together, then mask off the little stuff, then paint it, thereby protecting everything including the hardware and covers.

Great info!! Just a couple of questions:
Are you suppose to apply rtv to any of the gaskets?
Does anyone have the correct needle bearing counts for each bearing?

sure is the place if you want to get taken for a ride . . . .

$419.xx bucks for a master gasket / bearing kit for a np205 large bearing.

and I have never been a fan of web sites making you click the link to go to another page to see the prices .

Also if anyone sees anything I did wrong, let me know and I will correct it so I am not spreading bad info. I don't have all the spline counts for all the different 205's so someone else will have to add that.

Outstanding write up. It's greatly appreciated. Cheers, Jack

[rowdy11]

Killer write up! Thank you!!!

Just curious, how many needle bearings were there on the rear of the front output shaft?

[sweetk30]

depends on if older FULL needle bearing cup or newer style partial with cage .

if older full setup there should be no space left for another bearing needle .

Hello all, I just wanted to get a sanity check on what I'm seeing. On the rear output shaft, the rear end where the needle bearings get installed, in I'm seeing vertical stripes. I don't know if this is wear or if they were machined in and are supposed to be there. They look really clean and almost intentional. Also, what helps to complicate things is that I apparently have a weirdo metal drive speedo unit. I removed the snap ring and washer for clarity. I can't find any clear pictures on the internet of what it's supposed to look like. Thanks for your help!

[kwmech]

Those lines are not supposed to be there

[rowdy11]

I didn’t have any indentations when I replaced my needle bearings. I’ll try to find a picture.

[beanious]

Well... I'll be dipped.

[beanious]

Guess I'm in the market for a new output shaft

[sweetk30]

If it takes the early metal speedo gear i have a few . Send me a pm .
