Questions about a D31-16 Komatsu

i am trying to figure out how to adjust the steering on a d31-16. left pedal functions properly, the right pedal you have to really press hard on it, then it will turn the machine. i was also wondering how the clutch/inching pedal on the left side of the floorboard works, do you have to use it when you shift or is it just for inching. it has what i think is 3 forward and 3 reverse powershift.

the serial number plate says model..........D31-16
serial no.......26145

i have been trying to price some undercarriage parts and the dealer keeps asking what letter it is?? i am looking to purchase the machine and was wondering if they are decent machines and hold up.


thanks for any help and information on dozer:drinkup
