filter torque

Just got all my filters for my 300hr service. Looking at the hyd. filters they show 3-5 spins after contact are they really that tight ?

Sounds way too tight to me. I usually turn it 3/4 turn after contact of the gasket.

Well 3/5 = .6 and 3/4 = .75
So that does not sound tight.
Hst is high pressure.

I read SwampCat's 3-5 spins to mean 3 to 5 spins, not 3/5 of a spin. Looked at one of my hydraulic filters on the M5140. Says +2/3. This is a gear tractor.

It must be a typo in the manual.
Or there are realy fine threads on the nipple.

3 turns on a filter? 5?

My manual states 1/2 turn on hst and engine oil.
So I would go just over 1/2 or 3/5.
And rin it and check for leaks.

You're overthinking it. Put oil on the o ring on the filter, tighten filter by hand until its good and snug.

No, its printed right on the filters. Seeing as I am a Kubota virgin, just picked up a B7510 hsd last week with 298 hr. So I just got all the stuff to do the 300 hr. service. Put a lot of filters on in my years, just NEVER saw anything like this, so I figured come straight to the KNOWLEDGE base. Dont have a WSM yet so just going by what it said on the filter. As it stands 3/5th of a turn gets em pretty tight, theres NO WAY IN HEAVEN to get 3 turns on a filter.

Go eith 1/2 to 3/4 grunt and test for leaks!

I agree with the others go for the grunt and check it

I had some CAT filters that said 1 1/2 turns after contact which I had never seen before. I figured it could have something to do with the size as they would hold almost 2 gallons of oil. The first time I tried to remove them I ended up driving a screw driver thru the filter and using one of those good chain type filter wrenches at the same time.
I cut back to 3/4 'turn and never had any problem after that.

I changed out HST fluid and filters last week. One filter has the collar set up for a wrench, know what they look like but don't know the name. I ended up using a drift and hammer to get it off as a strap wrench wouldn't budge it. I know it's a high pressure system but the new one doesn't leak. Hand tight plus some. Hopefully someone will chime in about the filter with the collar, filters were K brand.

Oil the O-ring on face of filter and install filter to contact then add 3/4-turn to tighten. Shouldn't leak. Start and test looking for leaks. Even on the HST the filter is on the low pressure side.

One poster mentions using drift to drive filter off via wrench lugs. Was that a first time change since new? Every hydraulic filter I've encountered upon first removal has apparently been installed at factory both dry and too tight.

Best thing I've found is a set of three sizes ChannelLock PVC / Oil Filter pliers. Also available as knock-offs at HF and other discounters. Before ChannelLocks had to use small chain tongs on some first-time filters. What a useless PiA to have to do this on something as simple as a filter.

Please post back your experiences so we may all learn.

The tractor was new to me and had 458 hours on it. Fluid was drained and the other filter already swapped out, worked with what I had. FWIW anything other than the drift or lug wrench would have crumpled the filter. Did that once in my 20's, wasn't fun. Hand tight plus some ever since. I've always used whatever oil is being filtered but on another forum someone claims bearing grease is better.

I don't pay attention to the turns. Hand tighten and no problems.

Stubbyie - that is so true.

The worst for me was a Harley-Davidson oil filter. Man, that puppy was on there, and its a small one besides.

All I can say is OUCH! Where they are located is tight, and make a mess!! If memory serves, there was both some oil and blood on the floor that day.

Have had to take a chisel and hammer to more than one Grand L series HST filter....

 

[sheepfarmer]

Perhaps that's why the tech at my Kubota dealer said to me politely when I was asking about doing the 50 hr service myself, "those new filters are on pretty tight..."

when what he really meant was "you???? Don't be ridiculous!"

 

[Shadow]

Who's your dealer, sheepfarmer?

 

[sheepfarmer]

Shadow, I am making a joke, my dealer and his staff are really great, and treat me well. I am a little old lady, no hand strength, imagine the lady in the Belle tire ad.... Did change the oil on the old 8 N, not very often, but when I crawled under my shiny new Bota and looked at where those filters were located, I thought better of it, and took the hint.

BTW, I seem to remember hearing someone say eons ago, that if you couldn't get a car oil filter off, drive a screwdriver through it with a hammer and then use both hands to twist. Does that sound right?

I use one of these, and it works good. Can fit in almost any situation. 1/2" ratchet gives a lot of leverage.
