Hey Guys ,
Replaced trans sprocket seal and when tightening nut , shaft binds up. It is a 1975 FLH 4 speed. Used a Genuine James #JGI-35230-39-DL seal. Everything went together fine. Cleaned everything up after removing old one. Installed cork gasket , greased spacer , seal , and shaft . Used Hylomar gasket maker to O.D. of seal before driving it in. It has a seal nut with an o-ring on the back side toward sprocket. Key is in place , seal feels flush to case opening , put sprocket , locking tab and nut back on. HD manual recomends 140-150 ft. pounds torque on the nut. Before tightening anything up , checked main shaft and counter shaft by hand turning them in neutral as well as in gear. No problems noted, turns by hand . A little stiff but , not hard to turn. Tightened nut by hand until no sprocket side to side wobble. As soon as I tighten nut up the shaft starts tightening up. A couple flats more tightening and the shaft locks up. Can't turn it by hand!!!!! Any ideas where I might have screwed up??? Read manual procedure before hand , during work, and after to try and figure it out. I am missing something , just don't know what.

Never heard of Such Happenings... All I can Figger is something is Contacting More than the Inner Race of the Bearing ...in your Sandwich...Gotta Start over..

 

OK we see this before

the original seal was open backed single lip and the cork went into the open area

the usual replacement is a double lip seal and the back is closed ( no room for the cork it crushes and causes the gear to not want to turn ) as it compresses the works

the fix is another kit and start over - remove all of it - i have both in stock if i remember i will picture what i think happened and show the two seals

 

Racpres , Like that one "in your Sandwich"
Johnjzjz Everything tracks as to what you posted. The closed back seal looks much beefier, I assume that is the way to go ( without the cork gasket!!!! LOL!)
At least it isn't a major cluster, Live and learn from your mistakes!

 

Still getting used to the Forums guys. Hope this was the correct area to post this issue. Should I have used the Tech/Tranny section instead??

 

You're in the right place

 

Shovelhead and engine or trans is like - pees and carrots

 

I just did the same thing
i forgot a lot of things but Johns dead on no corky with the double lip
I used one of Rays bushings on mine and no drops on the diaper on the garage floor yet

 

...'cuz no one wants a dirty diaper :>)

 

Hey Guys, Got the new trans. seal installed without the cork seal. When installing the nut (seal nut with o-ring behind it ) , as soon as I get the nut more than hand tight , the sprocket is in a bind ! Hand tight using regular ratchet. Took it back apart and don't see any rub marks on seal , it is flush with the case opening. Spacer turns by hand , key in place. Put it back together. Tapped the socket against the sprocket a couple of times while spinning by hand. Tightened socket about a flat or two on the nut and cannot spin the sprocket unless using both hands or a screw driver! This seems way to tight and no where near being torqued. Any ideas? Or have I screwed something up????????? Slats
