I just purchased a 1969 AC HD3 loader and I have started to change all the filters and fluids. I replaced the air filter, the fuel filter, and the filter on the hydraulic tank, but I cannot find an engine oil filter. I looked in the manual and it shows the filter should be mounted on the side of the engine but it is not there. Can anyone help? |

Welcome to the forum! Does the engine in the picture look exactly like yours except for the filter? Wish you best with your new toy! ------------- Currently- WD,WC,3WF's,2 D14's B. Previously- I 600,TL745,200,FL9,FR12,H3,816 LBH. Earth has no sorrow that Heaven cannot heal! |

Sorry for not clarifying that I meant the picture in your manual. I wondered if per off chance someone had put a different engine into your machine? ------------- Currently- WD,WC,3WF's,2 D14's B. Previously- I 600,TL745,200,FL9,FR12,H3,816 LBH. Earth has no sorrow that Heaven cannot heal! |

| I understand what you mean now, my bad. Yes the engine looks to be the same as all the photos I have seen, and it looks like it has been in the track loader for years. I cannot think of why someone would remove the filter assembly but I see no bracket, or lines capped off. I will start it and raise the bucket so I can get under it for a better look but from the top and side I see nothing that even resembles an oil filter. I had a thought that maybe because it was a track loader AC located the filter assembly somewhere else but I think I am grasping at straws. Thanks |

I assume it is a diesel engine from the D in HD3? ------------- Currently- WD,WC,3WF's,2 D14's B. Previously- I 600,TL745,200,FL9,FR12,H3,816 LBH. Earth has no sorrow that Heaven cannot heal! |

| HD3's could be diesel or gas. Same motors as D-15 tractors... |

Dave: Do you know if HD3's became the model name for both diesel and gas in a certain year or serial #? I had one with a 149 gas and it was called H3 (without the D) right on the front page of the manual. ------------- Currently- WD,WC,3WF's,2 D14's B. Previously- I 600,TL745,200,FL9,FR12,H3,816 LBH.

| Thanks for the filter part numbers. I have yet to locate where the filter would be on my HD3 track loader. Unless it is remotely located somewhere other than the engine, it has been removed. I do not see any lines, or a filter bracket, and I am sure the manufacture did not produce it with no engine filter. |

Could it be behind the engine or even under the floorboards?

| I looked on the back side of the engine and could not find it but I did not look under the floorboards. I plan to lift the bucket and get under the loader this weekend to see what I can find. Thanks |
