Oil Filter Conversion Kit

[ilbdarned]

I have a Ford 3000 diesel (1966 model) tractor and have been thinking about changing out the canister oil filter set up to the spin on type. I have read that doing this reduces the oil capacity by one quart. I also read where some conversion kits purchased did not fit the tractor (they were 1/8th of an inch too big). I have the following questions:

1. Do you recommend making the change to the spin on type?
2. Does the reduced oil capacity effect the engine in any way?
3. If you do recommend the change, where is a good website to buy the correct conversion kit?
4. How do I know which oil filter to use after making the change?ve seen said was full

I greatly appreciate any help and advice that you may give.

My Ford 3500 gasoline 3 cyl was built in 1972, the manual I bought was a copy of the old school original owners manual, it said the capacity was 8 quarts which assume is with the huge canister filter. It was was bought used and had a spin on filter, I assume somebody added the kit, my Tractor is a 1972 model so I don't know for sure.
Anyway, I have never seen this before but my dip stick had simply an add line and up the stick where there should have been hash marks designating the operating range oil level was nothing, then stamped in further up the stick was the word FULL with no line designating if full was at the F or the last L.
My oil filter was the typical one used on a lot of Fords PH8A. So I started by putting 8 quarts, the oil level covered the word FULL and knowing 8 quarts is too much for a spin on filter conversion, I had to believe it was over filled.

All the other ford 3500 dip sticks I had seen online had a Full line right before the F on the dip stick where it was stamped FULL.
So I started draining the oil to try and get it there, right before the F where a line should have been.
I had to remove 2 quarts to get it there. So the HeII if I know where full actually is and what the oil capacity is, but the best I could tell 6 quarts got me to where all the other dip sticks I have seen said was full.
So if you have a dip stick that has a full line, your better off than I was.. So put 8 quarts in then start the motor till the pressure builds so the oil filter is full. then turn the motor off and drain out into your clean oil jug using a funnel holding the plug at the threads of the pan and remove a quart at a time, screw the plug back in and check the dip stick, repeat this till the level is at full. Then subtract what you removed from what you put in and you will not have to do this crap again. I have always hated Fords. Maybe my dip stick was a manufacture defect never getting the operating zone or full line stamped, but for me this has always been typical for fords. POS

Never a problem on old Farmalls. No dipstick...just two little drain cocks on side of pan. Want oil to come out lower, but not upper.

Yea but the responses here are for others with the same problem that looked up that same question and ended up here, I have got answers to problems others had asked 10 years ago.

I like when others add to a thread no matter how old it is, because it makes the thread more informative having input from people with different experiences.

Adding to a thread no matter how old it is, is contributing to the database so people reading it have more of a chance to find their specific situation , model or series of tractor. You can tell by the responses everyone has had a different experience answering the question considering differences in model, like whether it is diesel or Gasoline engine and which use different pans..

I think the key to answering how many quarts needed with a conversion has to be related to which spin on filter a person uses, because a filter can have the same threads and same seal diameter but have a different capacity factored in by diameter and length. 6 Quarts brought me exactly to where my full mark should have been, But if I found a larger capacity spin on, full could have been at 7 quarts, one quart less than the canister filter used.
I use to own and manage a quick lube oil change center, they make different capacity filters that fit the same vehicle on some models.

I bought a kit at least 20 years ago off ebay. Use WW 15w-40 and FL-1A Motorcraft filters like all my Fords (including my PU when I had a Ford)...but oil was 10W-30. Zero problems.
