D6 dozer having trouble climbing hills

vendredi 1 mai 2015

Hey guys,

I have this old CAT d6 dozer, I believe it's about a 56-58... Anyways, I've recently noticed that when I pull the johnson bar back to engage it and move, it has trouble climbing hills backwards. It wants to go but then just doesn't seem to have enough 'power' to get up a hill...even if I have the throttle all out. I can have the johnson bar fully engaged and it will just sit there and not move. I've never had this problem in the past and it just started happening. I can only make it up the hill going forwards if I get a little run at it and don't start directly on the slope...keep in mind this is all done in 1st gear. I also notice that as I'm skidding logs to my deck (in 2nd gear) it has some trouble making it up small inclines (these logs aren't very big, maybe 24'' dia and 40fters, skidding 2 at a time).

Description of hills...I don't exactly know how to describe them BUT I will say they aren't very steep. They are steep enough you'd have to put your pickup in 1st gear to get up them but nothing like a 1:1 grade. I'd say it's probably close to a 4:1 slope that I can't make it up in 2nd gear and maybe a 2:1 in first gear backwards.

I'm hoping it isn't the tranny and is just some sort of clutch adjustment as I know I need to adjust my clutch as well because it makes a little rattling sound when I engage the clutch but that should be a fairly simple fix from what I've heard...but wouldn't mind some input if you guys have any on how to do that as well.

Hope that helps with things and hope someone can help me out. Thanks guys!!
