HST Filter wont come off

[horses2]

I am doing the 50 hr service on my MX5100 and I cant seem to get the HST filter off. That rascal seems to be on there quite tight. Can I use a hammer and drift against the slots machined into the filter, or does Kubota have a special wrench for this thing?

Thanks,

IT should be snug rather than overly tight and a regular oil filter wrench should to the trick. However, in the event that won't work you can drive a large screwdriver through the filter and use that as a lever to remove it. Be aware that you will lose more fluid via this process. The idea is to change it quickly so you won't lose a large amount of the hydraulic oil.

They are a bear to get off, we used one of these: CTA Tools CTA Tools 2507 Bi-Directional Spider-Type Oil Filter Wrench - Automotive - Filters - Oil Filter

I honestly don't know about the hammer and drift.

Or one of these. Works every time.

Edit: Well, I did have to attach a Come-A-Long to the handle when removing the transmission filter on my L48. But the filter did come off undamaged and the chain never slipped.

Put a shop vac nozzle over the HST fill port and you will lose very little fluid,works for me.

Yep, chain wrench works well too ad is handy for other things as well.

I used my Snapon strap wrench

but any thing similar will do. even really big channellocks

I would not use a chisel or drift unless you want to punch a hole. Which is a way to get it off too. Just drive the punch through the middle, and out both sides. then you have a handle!

I have used a drift in the slots. Be careful and do not let the drift end strike the tractor. You only need to get it to move, then use a good filter wrench to finish the removal process. Kubota makes a tough hydraulic filter. Please use one from Kubota to replace the one you are removing. Heft the new one in your hand and examine the construction.

Yay!! another smart person!!:thumbsup:

Sounds like it was put on with a dry gasket. They will almost become one with the metal base when they are put on dry. When you put on the new one lube the gasket with some of the clean oil... it will come off much easier.

Don't recall any difficulties changing the HST filter on my little B but, on handy filter wrenches, I've had good success with the spider type of wrench another poster mentioned. It CAN crunch the end of the filter, though, if it's really stubborn.

The chain wrench looks handy, too. And, as mentioned, there's always the option of punching a hole all the way through the filter and making a big 'T' wrench out of it. That hasn't always worked too well for me; sometimes the metal just tears.

I've had very good results with a wrench like this

It doesn't destroy the filter and if more grip is needed a strip of emery cloth works well.

If the filter is so tight that a regular filter wrench won't remove it driving a screwdriver thru it will end up ripping the can open. After the can is gone sometimes a spanner wrench will fit in the drain back holes in the now exposed baseplate.

Of the many great tools snap on has there strap wrench is without equal!
In my experience a chain wrench is a pretty crude tool to wrap around a oil filter. Ymmv

I would think the hammer and drift would work to get the filter to move a little,then use the filter wrench as mentioned before.

Awhile ago I was servicing an L3540 and no way was the hydraulic filter coming off with any filter wrench-first 50 hour service.I used an air chisel with a blunt end punch gently on the filter flats-worked like a charm to start the filter moving,then followed up with the filter wrench.It was starting to look ugly.Good Luck!

My first filter change on my used l48 couldn't get the hst filter off with the channel locks I always use(in fact spun the can but didn't lossen the end) couple taps with the drift pin got it no problem. Ditto on the shop vac!

Had one on so tight I broke the typical HD oil wrench, broke the strap wrench, got a grip on it with a chain, and the can twisted off and the thread stayed on. Had to do a hammer and chisel on what was left finally came off.

Typical Kubota factory installed filter. Believe it was installed dry and torqued on using a five foot cheater bar. I use the snap-on large filter wrench for the hst and have had no problem.

One of these works on stubborn filters. Also good for grabbing anything round without doing too much damage. HF has one for ten bucks or less. Grab the filter at the end and you will not get too much crush before you get a strong grip.

I broke my never before failed, homemade strap wrench while trying to remove my oil filter. Things were getting desperate, so I bought a huge set of arc joint pliers (similar to channel locks). I grabbed the filter on the rim, near the connection, and they took it right off. (Note: I've never had a cheap pair of arc joint pliers didn't slip in the joint so, I got a name brand.)
