Seat post rod removal

#1

Post by craig60pan » Fri Feb 04, 2011 6:20 pm

Decided to take the seat post apart before I put it back in the FL and, as expected, found it was missing a few parts.
Got to the point of removing the seat rod from the plunger tube and it is tight as .......
Anyone have a creative solution/tool to remove it without damage to it or the plunger?
Thought about hammer and punch but was hoping for a better option
Thanks

CJ!

I hold the spannernut in my lathe chuck, and then twist off the tube using a wrench upon the toggle, and judicious heat of course!

Good Luck,

...Cotten

I hung my frame by the seat post, unscrewed the nut, ahd wacked the frame with a BFH.
(I had set a few blankets and stuff on the floor to catch the frame.)

CJ,
Cotten's advice is solid even if you don't have a lathe, you can get the same results with a good set of pipe clamps in a good vice that is properly mounted to something that won't move. Just "chuck" the plunger lock nut in the pipe clamps and turn the plunger by any means which will not damage it. Use care if you are trying to turn it by applying force only to the toggle itself. Gripping the tube by hand with nothing more than a pair of gloves may be all that's neccessary.

Sometimes its just too late for the old pogo stick, then any means that you have, even extreme, should be applied; dynamite, a BFH, etc., etc., until you get all the pieces out of the frame tube and the plunger disassembled. Here's the one that came out of my '31 VL

good luck!

Mike
the rest of the seat post is in really good shape so I'm hoping
that it will spin off once I get the setup right
won't have time to fool with it until tomorrow
stay tuned

Success
mounted the plunger in a vice by grabbing the toggle. Had my doubts about doing that but figured if it took too much force I would stop.
Then found this tool in my tool chest, it is a spanner to take the top fork cap off a Storz fork tube
A little Kroil and a piece of pipe for leverage and it spun off without too much trouble

CJ,
we all love a success story, glad it worked for you. A set of spanners is handy to have, even though not many assemblies use them, when you need it you got it. The Harley Lightweights have a recessed retainer in the wheel hubs that hold the bearings in (most of them have already been destroyed by a hammer and punch), the only tool that will get them in and out is a spanner with the proper size pins.

And Mike, I did put that entire seat post back in service, I poured the entire pile of scrap metal into a box and now use it as a door stop :lol:
