C160 Hydro dipstick being stubborn!

[Gary S Minnesota 62]

Hi All,

This evening I pulled the hydro dipstick in order to check the transmission fluid level on my 1975 C-160.  (the decal says to fill with 10-30 0il to full mark).

Now I can’t for the life of me get the rubber grommet/gasket to slip down into the fill tube.  The tube on this unit appears to be plastic or nylon so I’m afraid to get too rough with it.  I did apply a light coat of oil to the rubber surface that slides down into the tube but that didn’t help.  I’m thinking that the rubber has probably gotten hard with age. Are there replacements available?  Or any suggestions?

Thanks!y

They swell too. 

You might be able to remove and replace that O ring. I may have a replacement dipstick here.

It appears that the rubber piece is molded rubber,  not an actual O ring.   I will take a closer look at replacing it.

Other wise I’d be happy to purchase a replacement dip stick from you if available.

Thanks for your response

Measure your existing piece and I'll see what's in my parts stash.

@Gary S Minnesota   dielectric  grease ?   made for that  , rebuilt  hundreds  of pumps  / gear  units , makes a  ring slide with ease , another thing it does is stop , o ring twist / leak , also excellent  on fuel tank bottom valve  grommets , makes it easy . pete
