How to remove a oil filter when it is too tight?

[Hurricane]

I've always use one of these:-

I've always put a socket bar on one end and it works reasonably well,
The strap in the image has a different drive size on each end so will fit different sized socked wrenches.
But an engineer who helped me with my major service had a better way of using it.
Put a wrench on both ends of the strap and that evens out the applied torque making it shift even the most stubborn of filters.

now that’s a top tip!

I have the same strap....never thought of that

Get one these they just grip the more you turn better than the nylon strap type as they can slip on tight filters

I have recently had the same problem on one of my TAMD 61A engines.
In the end I decided the safe way was to remove the filter housing complete by undoing the hoses and a couple of bolts holding it on.
Took the whole thing back o my workshop and put in the vice and even then had a struggle.
Recently bought this boat so not sure when the filter was last changed.
Lubricate the O ring well when fitting the new filter and only tighten firmly by hand.
Theye do not need fitting with a wrench

Having stuggled with rubbish filter straps before the one that has never let me down or broken the filter is the chain type.

Metal on metal bruce?

I look for the top flange, I have a blunt chisel and use this to dent it slightly, put the chisel at an angle and keep tapping until it moves and begins to rotate and unscrew it.

I did a Diesel engine course with Mermaid marine many years ago. A top tip from them was always lubricate the o ring and then smear a little oil on your hand before hand tightening the filter. Once it starts slipping in your hand, it’s tight enough.

Great tip.

Didn’t know they existed until I saw one being used recently by a marine mechanic, he also said the chain was the best way.

Yep. Chain grips and doesnt tear the cannister. Never let me down as said.

I sometimes use proper pipe dogs Bruce, set chain length and the huge teeth on the head really grab them.

Not that it helps the OP but most filters have a hexagon formed into the end which is intended for a larget socket spanner, anything from 32mm to 74mm, eg:

Until recently I didn't know such a thing existed, I've always used any of the methods mentioned above.

Many of the formed hexagons are he same thickness as the main can and are merely pressed, often on stubborn filters it simply deforms when you put any real pressure on it and simply damages the filter housing anyway.

Servicing the genny this morning and ofcause the oil filter was solid, only a fairly small dia ~65mm. After a few curses I and checking what tools I had onboard I found an old G cramp, perfect size, 2 minutes and the filter was off.
