It's all straight gears - hand clutch - lever steer - steering clutches with foot brake . several changes over years of production - couple different configurations on engines . 24 V electrical system . around 60 HP track and undercarriage same as on HD5 but extra roller over HD5G or E - rear housing same as HD5 - ------------- Faith isn't a jump in the dark.

| Longer track and better balance than HD5. 344 cubic inch has 3 versions (HD344 ,6000 and 7000) The turbocharged 105 HP motor was not installed by AC but is a direct fit choice at rebuild time. The 7000 motor is from the HD7G and government surplus generator sets. Preferred machines above s/n 13322 |

Should be a turnbuckle, and locknut, coming back from the front idler. Coke would be prolly the best here, to describe the procedure...

Not really a turnbuckle,the large shaft pushing the idler is threaded on the back end.Generally rusted and a pain to turn,also has locking mechanism,the HD5 used a diamond shaped nut with 2 bolts to lock.Mostly a HD6 is the same running gear as a HD5,but could be different. |

I stand corrected, I knew it wasn't a greaser, though...

| If you can not turn the track adjusting screw you can put "U" shaped shims between the yoke and idler brackets. You need to free up the adjusting screw though. If there is a grease fitting on the yoke remove it and put some anti-rust stuff in there to help free up the adjusting screw. If there is not a grease fitting, drill and tap 1/8NPT for the fitting. |

I appreciate the information, on the back of the yolk where the grease fitting is do you have to loosen the 2 smaller bolts before you turn the threaded shaft? (is this the locking mechanism) then turn the threaded shaft? Operator for almost 30 years but this thing is older than I am and it is taking some getting to know. Any other tricks of trade hacks ect. would be greatly appreciated. Thanks, Darrell

yes loosen the two bolts they lock the threads when tightened. then turn shaft and relock or it may work loose ------------- Me -C,U,UC,WC,WD45,190XT,TL-12,145T,HD6G,HD16,HD20 Dad- WD, D17D, D19D, RT100A, 7020, 7080,7580, 2-8550's, 2-S77, HD15 |

| Let it work loose, tighten, and do it again, it'll clean up the threads... |
