Hey I just bought a cat d4h and was wound wrondering if it is normal that you have to idle it up to go into gear? Vic
It's a 1991 model series 2
When you say "idle up to go in gear" are you meaning being able to put the gear lever in a gear position or for the dozer to start moving? My 1988 D4H easily shifted at any engine speed but moved as soon as it was in a gear position unless the decelerator was pushed all the way down.
It goes in to gear at low idle but will not move until you rev it up bout half way!!
Well, some of the real experts on here may be able to tell you what is going on, but it sounds like your trans pressures are low. Hows the trans fluid level, have you changed the filters and fluid yet? Off topic but I graduated from Murray State 30 years ago...
Level is fine!! But I have not changed the filters!! Another question is do I always need to press in the decelerater when I shift or go from forward to reverse!?
It's easier on the power train gears if you decelerate to shift. If you have a trans pump flow problem you will have trans overheating problems. Later Bob
If you are moving on dirt then that would not seem too far out. The only way a tractor will generally move with the engine at idling speed is with absolutely clean undercarriage on hard smooth concrete. Regarding the decelerator it's definitely a good plan to use it most if not all of the time during changes of direction to reduce the load on the transmission. The factory put it there for a reason...!
Ok thanks guys!!
