New here from markham with a pathfinder

You can pickup a Pre Cleaner at any farm equipment dealer.

There was a time that every tractor had one.

donaldson has some really nice ones, smaller and less space ship looking, lol.

[HotWod]

The one I have is Donaldson. You wanna make sure it has the proper CFM rating. Otherwise you'll starve the engine of air.

[CruiserRomey]

that's right, good point Rod!

[Muddyr50]

Do you have a part number ? Or by chance know what the cfm rating I should be looking for ? Thanks. Gonna look into collecting the parts soon

? Or by chance know what the cfm rating I should be looking for ?

I haven't looked into this before, but in thinking about the math...

3.3L engine = 3,300cc

3300cc/revolution @ 6,000RPM = 3,300*6,000=19,800,000cc/min

Convert to imperial, 2.54cm/in: 19,800,000 / 2.54^3 = 1,208,270 in^3/min
Convert from in^3 to ft^3: 1,208,270 / 12^3 = 699.2 ft^3/min

So, assuming a 6k redline, you'd need 700cfm, perhaps round it up a little for safety, 750 maybe.

How'd I do?

The Donaldson part number is H000820 and the closest Traction Truck Parts is:

498 Markland Street
4
Markham, ON
L6C 1Z6

[HotWod]

hahahaha Jeez Ron, if you put that much effort into your truck, it would be 10 feet tall! ;-)

[Bow_Tied]

LOL, it's a GM, it'd just fall over at that height!!

I can spend a bit of time in the evening on the net, getting a day in the shop is tough with a family on the go, house renos, regular vehicle maintenance, blah blah....

[CruiserRomey]

also, anyone you know with an amsoil account can get that donaldson part for ya...prolly for a lil less.

[Muddyr50]

Wow you guys are awesome. Thanks so much.

How'd I do?

4 stroke engine - intake, compression, power and exhaust - so the each cylinder is drawing air every other revolution.

3300 cm^3 * 6000 rev/min / 2 (4-stroke) = 9,900,000 cm^3/min = 349.6 ft^3/min (cfm)

With the same assumptions add a suitable margin to 350 cfm.

Depending on pipe diameter these are the Donaldson part numbers for the 200-450 cfm pre cleaners

Full-View TopSpin™ Inner Inlet
Pre-Cleaner Pre-Cleaner Diameter
H000820 H002425 3.07"
H000821 H002426 3.83"
H000858 H002394 4.06"
H000823 H002427 4.56"
