520 power steering vane seals

[dvtw]

Going through my steering pedestal and replacing all the seals due to a leak from the bottom of the pedestal assembly. Anyone care to share tips to sliding the vane seals over without cutting them. Is there a trick that works best?

I boiled mine for about 5 minutes. It made it just pliable enough to slip on without tearing one. Using thin long flat head screwdrivers, I just worked them on.

Warming them up with a blow dryer on high heat for a couple minutes makes them nice and pliable. Also, smear the vane and vane seal down with grease. Use a round shank screw driver (not the smallest on in your toolbox; rather a larger diameter one to help in not tearing the seal)

Hope this works for you...those of us who've rebuilt them have likely torn a seal or two....I know I have on the 10 or so that I've redone.

Good info here already and warming them up really helps. I use Vaseline . Also these are the same seals in the rotation motor on 825 , 835 and 845 rollover plows .
