OK, just got the new seals from Spider. Indeed the number on the box is W20HH100, but, on the seal it says it is a CR 35000, common seal. It's just too bad that Spicer would not give this number instead of their number so you could at least go for interchange if you do not have the CR in stock
They will install a Speedy Sleeve or Wear Sleeve tomorow, they say the shaft was worned when they took the old one out the last time they did it. OK, now it is worn!! Why the hell they did not install a sleeve the last time?
Anyway, the bill is on them, so they can do whatever as long as it stops leaking for my next trip to Mexico.
