Oil filter for ATF/hydrdraulic oil???

[andrewcanada]

Has anyone thought about/installed an oil filter on their oil lines? Would it go on the supply or retun?

You could run one,like a small external trans filter style.It would help keep some of the dirt out of the pump.You would install it on the return side.

Don't install one on the pressure side of the pump! It would explode from the pressure.

Most cooler lines don't have much pressure in them,so it really doesn't matter where you install it.Dodge may be the exception,as they can see well over 100 PSI in OD.

Now that I think about it,it may be better to install it on the trans outlet line,to keep the crap out of the cooler(s).A lot of the newer style coolers have very small passages,and can get plugged up quite easily.Some filter heads have a temperature sender port,so you can install a trans temp gauge.You normally want the gauge in the hot,or outlet line from the trans.

Most of the ones we have installed are done after a trans failure,and go on the return side to prevent any debris in the coolers from being dumped back into the transmission.

Meyers/Diamond used to have an in line filter available when they were making belt driven pumps. I don't know if it's still available, it's been a few years since they dropped those pumps. If I recall correctly, the filter also absorbed moisture. It resembles the in line air filters you place on paint guns.

Hey Chris,

Would a conventional oil filter set-up like this one be sufficient -- or is there a better way? (like an in-line filter)

That kit would probably be overkill.

If you wanted a setup like that,just buy a cheap filter head at the hydraulic shop,and plumb it yourself.There are also cheap ATF splice in filter kits available.

Check with your local tranny shop too,as they may have one of those cheap inline style filters they use after a rebuild.They look like a small fuel filter.

Either way you go,itwould have to go on the return side.

I found one of the Meyers filter kits, here's a pic of everything included. Part # is 816000255

Getting back to the original question, whats the advantage of a filter if you change the fluid every year?

[Pelican]

The same as putting a filter on your engine!

These filters prevent any debris or foreign matter from getting into the pump to cause damage, or from entering the valving. This is especially important with solenoid type valves as I had on my Diamond plows.

Annual oil changes do not guarentee that problems can not develope, they just reduce the risk. An in line filter reduces that risk further.
