Stondad,the windshield wipers were vacuum and it was just accepted that you lived without them on a pull,that was cars and everything back then.My,how times have changed.Chrysler Corp was the first,back in the '40s to have electric windshield wipers and I was not yet in my teens but they won me over at that tender age because I figured "duh",what took everyone so long?
Now,power dividers.......this is what I remember as applied to the Mack bogies......they are designed to distribute the power to all four drive wheels according to which wheels had the most traction with only a certain percentage going to the wheel with the least traction and I cannot remember the number but lets say it was 60% then the rest of the power went proportionally to the other three axles.The purpose of the power divider lockout switch was to eliminate that power dividers help which then guarantees that one wheel on each axle will get power.
If you happened to have the truck in a situation where one wheel was freewheeling which happens quite often doing site work,mixers etc then an old trick that most drivers don't know about and the old f*rts like me just smile when they use it is to leave the power divider engaged and when you attempt to move the truck out of the helpless situation is to pull the trolley brake on a little or even just step on the brake treadle a mite and the truck will walk right out with everyone scratching their head wondering "why couldn't I do that"?I have done it many times over the years now here I am telling everybody.Of course what happens is that the brake pressure on the freewheeling drum stops the wheel from turning and the wheels with the traction now get the power to drive the truck out.Ya' gotta love it!Now everybody knows.lol.Ron G
