tracterbynet oil video - comments on video

[tstex]

Hello to All,

I saw the JD video on how to change the oil sent out by Tractorbynet. I really didn't learn anything new, but some comments made, I had heard previously too. "Add some oil to the oil-filter before you install it".

Well, I always added some oil to the top of the filter to lubricate the seal, but have never put any oil into the oil-filter before installing. I've changed the oil on 2 tractors, riding lawn mowers, six-wheelers and many other combustion-based engines that have oil filters. Decades afterwards, they still operate fine and I have never had an oil leak or lost compression of any significance. How can not adding oil to the oil-filer prior to install "starve the engine" for oil, that for any significant time would cause the least bit of damage?

Next, if you view the video, 2 things it does not say that are key [at least to me], is that you open the oil intake cap before you unscrew the drain plug. The video says to loosen the plug, then drain, then put plug back in, then change filter, then replace, then fill w oil. By not loosening the intake oil cap, a vacuum is created. The cap should be loosen for both the oil drain plug and filter removal.

Next, a more subtle point is to park the tractor on level ground. The video shows the tractor parked on a concrete shop flr [I hope it's level], but does not state it...I a lot of oil is changed on grass or dirt grounds and it's best it is level ground.

Regards,

This was common practice on large filters that sat with the gasket upwards. It would take time to actually fill the filters with oil (up to a few quarts) and during hat time all of the bearings etc ran dry. I still do it where and when I can just to negate that.

Hmmm, I always pre-fill vertical oil and fuel filters. Why not? The oil fill cap I remove just after pulling the drain plug. It makes the initial splash a little less messy.

Like both above have said....
Vertical filters get filled, On Horizontal filters I fill them half full, there is no oil escaping during instillation that way, and as Z said... Why not? ... KennyV

Thx for feedback. I can see where a huge filter that is installed upright requiring 2 qts of oil could be filled. horizontal installs, that have to be moved upward while laying under an F-150, she's going in DRY.

If anyone changes their oil w/in 15-20 minutes from when it is initially drained, plus the engine was only warm prior to draining, there should be enough residual oil to keep things going...remember, you are only starting the engine, not putting any force on the engine by engaging the tranny or accelerating, so the time it takes to fill the filter and circulate the oil, I doubt whether any damage would incur.

PS - Why not? spillage, dropping filter, etc...why? if you can install it dry and no damage? we can leave it as preference...best to all - tstex

On tractors Filters are usually very accessible so its easy to prefill. I've changed filters on some automobiles that need an extra elbow and a universal joint installed in my arm just to get the threads started so prefilling is difficult without spilling. Makes me miss my old F100 with the straight six.

The big question is, how clean is the oil you are putting in the filter? I have seen lab tests were the oil coming out of the sealed bottle was dirtier than the oil being drained out of the engine, transmission, etc. Are the particles large enough to damage your machine, who knows.

If what you doing works, don't try and "fix" it.

I will continue pre filling my filters. Thanks.

 

[tstex]

As stated, I think what works for you, stick to it. I was just cking to determine if anyone had any compelling reason to pre-fill an oil filter due to damage by not doing it.

Thanks guys and hope everyone stays safe, tstex

Interesting comment on pre fill but they are talking engine oil. One of our John Deere tractor's fuel filters warns against pre-fill. At Caterpillar we had so many injector wear problems that for some engines we used 3 filters with the final upside down due to people pre-filling. Analysis of fuel delivered to job sites determined a large portion was dirty enough to damage the high pressure injectors by using just one filter full of dirty fuel. The inefficient fuel injections of the past and on very small diesels are not as important but anything with a very high pressure modern fuel system and is especially prone to damage from dirty fuel. In the Kubota world my RTV and GR2120 with 1,500 psi injection systems have one little in line fuel filter while my M135GX with a 23,000 psi CRS has 4 fuel filters. Now engine oil is less likely to be contaminated unless it's pumped from a bulk barrel. System pressure is low. However an engine that has been run already has an oil film in all bearings sufficient to prevent wear at startup so in small diesels it's not a concern although pre-filling with clean oil is not likely to hurt. After all the '61 Chevy my wife owned when we got married did not even have a filter - that was a GM option until the late 60's - and they were good for 50 to 100k miles before first overhaul.
