I have a 1961 Allis Chalmers H3 dozer with a 149 cubic inch gas engine. I finished up with rebuilding the engine and need to get a new oil filter for it. The one that was on it was a S-01 STP brand. When I rebuilt the engine, it had a partially spun a crank bearing. Since the oil filter is upside down, I'm wondering if there should be a check valve in it. A check valve would prevent the oil from draining out when parked. Hence, I wanted to double check this forum to see if anyone knows what the "right" oil filter brand/part number is for this engine. I suspect that it should be the same as one for a D14 or D15. I also need to replace the hydraulic filter too on it. If anyone has a part number for this one, it would be greatly appreciated!  Thanks for your help! |

Pretty sure the oil filter should be right side up (threads towards the ground) like on the D14 and 15 tractors. If the base has a small tube running up the middle, use a Fram C159 filter. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| By the parts book this filter has a different base than the one that uses the C-159. It shows the AC filter number is/was 237000. The STP S-01 and the 237000 both cross to a Wix 51515. Wix also shows 51452 as another cross to the 237000. Both the 51515 and the 51452 have anti-drain back valves. The burst pressure and the dimensions are slightly different between the two filters. Ford and Chrysler are couple that used these filters. |

| Sounds as someone replaced the base probably off a later farm tractor as My 180 and others are upside down. |

He has the right base by the book. The threads are internal in the filter element like most current spin-on filters. It threads down onto the post in the base. This is right side up for this base, upside down to look at, I guess one could say. And the STP S-01 filter has an anti-drain back valve, by its specs. |

Thanks everyone for your help! It's good to know that oil filter that was on it wasn't the problem. If anyone knows the hydraulic filter part number, I would would appreciate it!

| You can find a parts catalog for your machine at https://www.minnpar.com/" rel="nofollow - https://www.minnpar.com/ so you can find part numbers. The parts catalog shows the filter is # 239930 (current AC number is 70239930). Some cross references are: Wix 51049, NAPA 1049, Baldwin B9, Fram PH11 |
