[Healeys] Steering idler bits

Jim - ouch that's hot!  But I'll bet that the Penrite - or John Deere corn 
head grease, which seems to work just as well (according to others) will not 
run at those high temps.  I used the Penrite because I managed to ahold of 
it, otherwise based on what others have experienced, I would have gone with 
the John Deere stuff.

One 500 ml bottle easily filled both the steering box and the idler

earl, living here las vegas not only penrite, but even CV joint grease will 
leak out if the seal is not snug.  115 here last
week and the grease in my grease gun was almost liquid.
