Wasn't sure where to put this thread. "Weeks and tires" seemed like the best spot. :)

I own both a Topeak Road Morph and a Topeak Mountain Morph. Both pumps are great and I've had them for years.

Recently, the Road Morph sounded gritty when I pumped it. This was after my (kind of) recent road crash in a deep puddle that almost submerged my bike and definitely did submerge the pump... I wanted to fix it and decided today was the day to try! There was sitting and tinkering with the pump and a few "Hey, that also comes apart" moments. Here is the result.

** CLICK ON ANY PHOTO FOR LARGER VERSION **

The pump...

Image


Air tube cap (under the pump handle). Looked like I'll need to make a tool for this... :D

Image


Everything else used metric allen wrenches.

Image Image


I took an old spoke and bent it into a "pin spanner" of sorts.

Image Image


Insert into the cap and unscrew.

Image


Nasty...

Image Image


Disassemble the rest of it...

The bottom also unscrews. I had to grip the air tube with a piece of rubber so my hand wouldn't slip.

Image Image

Image


Check-valve assembly can be pulled out of the bottom of the air tube.

Image


All clean! :D

Photos of the cleaned parts before reassembly.

I put a couple drops of light-weight fork oil in any spot where the o-rings move.

After reassembly, the pump moved smoothly and made a really nice "pfffsssshhhhh" noise. :lol:


Using my floor pump, I inflated a road tire to 110psi. I then connected the Road Morph and gave it one pump of air. I really had to lay into it at that pressure to get the air past the check valve...

Image


Gauge reads about 130psi.

Image


Disconnected the Road Morph, reconnected my floor pump, gave it one more pump of air. Floor pump reads about 112psi.

Not sure which is correct (I don't have a good presta air gauge); but, it's good to be aware of the disparity.

Bottom line, the Topeak Road Morph lives again!
