Affordable Donaldson air cleaner that fits an FJ40 fender?

Dan, I downloaded the Donaldson catalog, and did the CFM flow specs, etc.

Your FPG070017 is made of plastic. I'd prefer metal, so the closest metal version is the G065551. Price is very close to the plastic version. It's an inch less in diameter, and not quite 2.5" longer. I think it will work out better on the fender, because that allows the vacuator valve to be placed further to the rear.

The plastic is supposed to be stronger and more vibration resilient. The filter company I went to here deals primarily with mine equipment, and they said that virtually all of their customers have switched to the plastic units. I can tell you that it's not in the least bit cheap or weak feeling. All of the new ground support equipment at the airport is using plastic housings now too.

I'm going to make cardboard templates of both units, and see which I like best. Unlike your 45, I have marker lights on my side apron that I'd like to clear, and I'm running a second battery, so the plumbing to the carb has to be between the battery and the master cylinder.

Good plan. I don't really have a preference for metal or plastic, but the fitment is important. Either will last a long time, and filter the air very, very well, but if one fits better than another...

Prices are as follows:

G065551 $123.40 (this is the metal unit, but does not include a safety filter)
G070017 $129.78 (this is your plastic unit)
G070018 $128.68 (this is like yours, but has a 90 degree outlet, which I'm curious why you didn't go with this model?)

I didn't get the 070018 because they didn't have one in stock. They'll take it back and switch with me if I really want, but since this one looks to fit well (it's actually going under the hood of Dad's 40) I'll stick with it. When I buy one for my 45, I'll probably buy the 070018 for just that reason.

I was just antsy to get my mitts on a filter and stick it under the hood and whatnot to make sure it would work. Since this straight exhaust one will, I'll keep it for this truck. Next time I'll probably go with the 90 degree exit.

The downloaded catalog gives part numbers, but no illustrations, for the accessories, like bends, hoses, inlets, etc.

The question was asked about the benefits of a Donaldson air cleaner. In addition to what was posted, I want a cold air package, meaning I want to bring in fresh, unheated air to the engine, rather than intaking hot engine compartment air. This can be done in several different ways, not just by using a Donaldson air cleaner. I also want to have decent fording ability. Instead of running a snorkel and fitting it to an internal air cleaner, a Donaldson not only makes more sense, but compared to snorkel kits it's a lot cheaper.

Totally. The intake is a standard size, and there are lots of good options to attach heads/snorkels to the donaldson.

This thread prompted me to research replacing my filter. I pulled the filter and got a part number. Went to Donaldson's website and cross referenced that number to another part number. Looked at the picture and specs and it matches what I have. Clicked on the application table and found 1553 machines, for which it is an OEM filter. Decided on a John Deere 3300 Combine. Looked at their website and parts drawings and they show the assy, elbows, fittings etc. So, going to John Deere dealer tomorrow to order an air filter for my Australian Landcruiser.

UPDATE: Picked up filter from JD and it fit perfect.

As requested. These are mostly filters for high dust environments and less of a water snorkel. They are made to take the filter out of the housing and shake the dirt out of the filter and reinstall; hence their use on farm, construction and mining vehicles. Most people comment on water fording when they see the snorkel. I have had this truck in water above the tires, but never above the housing, so not sure how well it would perform submerged.

Can anyone here honestly say that they have had problems with a stock GM air filter assembly on a SBC in a Cruiser getting clogged with dust? If you are one of those guys who DOES experience heavy dust once a year maybe.... stop during your lunch break and knock the dust out of whatever filter you have... or throw in another $10 filter and blow the dust out of the fisrt one when you get home.

And does anyone really thing that an air cleaner like that on the fender without a snorkel up from it is good for any sort of serious water crossings?

Even the factory air intake in the front corner of the engine bay suffices for cool air intake, and snorkel will solve the problem as well.

If you like the cosmetics of a fender mounted air filter like that, then go for it and call it 'cool". but seriously, you really can not justify it on a daily driver or recreational use Cruiser from a functional point of view.

Well, do you have any other issues you need to get off your chest? I think we agree that the Donaldson is NOT for water fording. Didnt I say that? I only mentioned it because everytime I stop for fuel, the _eep guy has to say something about crossing rivers and bs. So because someone asked on an information exchanging forum, I am trying to make clear the manufacturer's intended purpose for this filtration system, not sell it. As for whether this filter is necessary....No, don't need it here in the granite state, but that is the way my truck came from AU and I choose to leave it that way. Kind of respect for the hard life it once had. Sorry you do not approve. :flipoff2:
 
The Donaldson dealer here doesn't seem to think that water fording is an issue as long as the stack is above the water. The Donaldson is better sealed than most OEM air cleaners. The dust bulb is designed to discharge dirt, not suck anything in.

The biggest issue I came across is the flow chart. 4 and 6 cyl gas and diesel FJ40 series engines are not an issue, but a 350 V-8, even at a modest 3500 to 4000 rpm, requires a pretty large Donaldson.

Relax, and save the snide comments for a real argument with someone. This thread is not about you and neither were my comments. I would have quoted you like I did this time if I was responding specifically to your post.

You are not the only person with a Donaldson and not the only person in this thread talking about them.

Nice filter system. I have one around here somewhere myself. If you like your truck the way it is... I am not gonna tell you not to.

Doesn't change the facts or my thoughts about the need for a setup like this.

These are definitely sealed and suitable to submergence. My point was though, that without a snorkel on top of it, the air intake is too low to suffice for water crossings. Really no higher than the OEM intake point and not as sheltered from splash and waves either.

They are nice units, if you do not mind the bulk and therefore the need to mount it externally. Just hard to justify using one on 99.999% of the rigs out there unless it is the cosmetics that appeal to you. Particularly when you find that it interferes with function (flow rates for a V8...).

I just want to add a bit of info here. First, I'm not wanting to do anything more than maybe help others understand. I don't know where Brian in Oregon is coming from and I'm not trying to speak for him.

But,---- most people think of Oregon as a wet state. This is true of only the western third of the state. The rest of the state (the high desert country) ranges from tall pine country, like you see when watching the old Bonanza tv series, to juniper, sage, southwestern type rock formations, huge dry lake beds, and alkali and sage covered flats.

The soil in the eastern area in the summer is very dusty, powdery, and often an abrasive volcanic base. The alkali areas are just as fine a dust as talcum powder, if not finer. In the alkali flats you look across miles of nothing, not seeing any vehicles, yet know exactly where every vehicle is because of the alkali dust clouds rising hundreds of feet into the air.

If Brian spends very much time in that area, especially around the alkali flats, I can understand his interest in the Donaldson air cleaners.

Again, I'm not talking for Brian, just hoping this helps others understand what can be found in Oregon besides rain and moss.

I agree with you though that simply using a Donaldson filter doesn't make it a fording machine by any means (we used it because we needed a filter, and I like the filtration provided by the Donaldson, and I didn't have a Toyota cylindrical filter sitting around).

I can't comment on the "performance" of the filter though, because the truck isn't on the road (yet). But I'm not in the least worried about it flowing plenty for a turbo'ed 3B. At the moment though, I'm planning on using another one with my 1HZ/Turbo...

Actually, yes, I do spend time in eastern Oregon, particularly in dry, dusty areas. However, in three decades of driving there, I've only had an air filter totally clog up twice, though they do get very dirty and need premature replacing. I also have to do fording on some of these trips, and at times over the height of my tires (they're 33"). That puts a lot of water into the engine compartment. I want to run a snorkel, but still need a sealed air cleaner setup. A Donaldson makes that convenient. I have not found a standard style air cleaner that I can easily modify and completely seal. It would be a lot easier if one was made, then there'd be no need to put a Donaldson on the fender, assuming the dust problem is not an issue. And there are indeed extension stacks for Donaldsons, resolving the issue whether they are suitable for fording or not because their intake allegedly isn't tall enough.

Going further, I'm surprised those speaking out against the Donaldson have not continued their train of thought further to speak out against unmodified tailpipes. If you kill the engine in the middle of a stream, and the water is over the height of the heads, it's possible for water to flood into the exhaust system and enter a cylinder. This is why military vehicles that do deep fording have extended exhaust stacks. It's not enough to run a snorkel to the top of the roof for fording while leaving the exhaust untouched. It's all part of a package. When I see a snorkel setup like that but no extended exhaust, my thoughts are that it's being done for dust control, not fording. There are other things on a vehicle that need attention for fording as well, like axle vents, PCV intake, etc.

BTW, one of the last trips I made to eastern Oregon last year I managed to kill the engine in the middle of a ford. I don't like to shift while fording, and entered at an imprudent speed in too high of a gear. The bow wave went over the roof, and the water poured into the truck through the door windows. Water also came through via the holes in the firewall. The air cleaner element was quite wet.

I have not seen anyone "against the Donaldson", but since I am the only one not cheering on the Donaldson swap here in this thread... I will address the comment about exhaust and water entry....

Currently the exhaust on my #1 trail rig exits the rig over 4 feet off the ground. In the past I have actually run a stack to raise it as high as the intake snorkel. I may again in the next evolution.

But realistically it is very very rare to stall while in deep water. So long as the engine is running, you will not get water coming in via the exhaust.

Your intake is vulnerable to momentary submergence or even heavy splashing. The exhaust is not.

I am surprised that you can not find an plain Jane old school V8 air filter assembly that is or can easily be sealed. I have never had do look more than a few minutes at a boneyard to find one. The best I have found are the ones from ford diesel power pickup, mid 80s - mid/late 90s IIRC. But I have three or four different types of GM and Fords assemblies here that seal up tight very easily. I am sure that there are others. Cheap, simple, compact and I can pick up replacement filters anywhere.

I would love to have a donaldson on my rig. I do more long-trip/expo style driving with my rig so the benefits work out... especially with a turbo.

While I understand both sides of the argument, the other benefit that a lot of people forget is that the OEM aircleaner in a 40 (diesel especially) is that they are HUGE and take up a ton of space. Since I intend to add a third battery (two for my 24V system and one for a separate 12V system with it's own alternator), heat exchanger for a shower, racor filter, and intercooler pipes, the space earned by moving the AC outsdie of the engine bay will be greatly appreciated. Plus, while it might be overkill to have the high level of filtration from a Donaldson, what on a cruiser has not been overbuilt? When I drive across this or other countries, I want the least amount of stuff to worry about. That's why I drive what I do!

Just my .02 and not directed at anyone....
 
Here's one I purchased today. Sitting on the fender of my 45.... FPG070017 is the model. The FPG is the series.

Look closely behind the fender. The small tube pointing down at an angle is a dirt/dust drain and is the only part that must point down. The rest of it can be rotated just about any which way along it's longitudinal axis. This drain tube is one of the features of the new Donaldson filters. It's supposed to make the filter element last even longer.

And here's the details on it. This is a kind of big model, but it has a 3" outlet, which matches the inlet on the turbo for this truck.

I purchased it locally at Albuquerque Filter for just under $120. In addition to the filter, I've got an intake cap, and a 90 degree tube attached to it.

Further note: this setup will, I think, be installed under the hood of Dad's 40 (with a 3B/turbo in it--see the sig for more info).

In addition to what you see here, there's a clamp that goes all the way around the filter and mounts it to the truck.

What did thislook like under the hood
 
Quick search... it looks much like It looks on the fender... you’d need to make room for it.

I have a snorkel that uses my ‘78 air cleaner, in lieu of an air box.

I have a ram on top, but am planning to buy a Donaldson’s pre-cleaner, to alternate with the ram, when bugs are thick.
