Tempest Oil Filter Mess

Why is it wrong? Just because you still use DC-4 doesn’t mean you’re right. I used to use DC-4 on the old Tempest filters but haven’t with the new ones, per the directions, and have never had a problem.
I just found out about the new ones with lube already on the gasket. Thank you for getting me updated. I bought a case of filters at a good price a while back, and just installed the last of them.
 
I use a tool like this for those really hard to remove stripped or tight oil filters. Place it as close to the base as you can, and the metal band tightens as you rotate it to get an even better grip on the filter.
Please see post #16.
 
If you read the instructions, and don't lube the filter, a strap wrench shouldn't be necessary.
 
Some filters are stuck just because the installer didn't use a torque wrench to tighten it to the spec. If you just use a plain wrench and do it up to what "feels about right" it will usually end up way too tight. It's the same thing that results in overtorqued bolts and nuts and the damage that does.

And then there are those that lubricate Tempest filters...essentially gluing them in place!
 
I always TQ to the lower end of the spec. Use a breaker bar and short socket with no extension. Never had a problem.
 
I know it's an old thread, but some gorilla put my LHE filter on at annual, a tempest, and apparently they followed the "just add oil or DC4 to convert this dry lubricant into a steel-welding epoxy mixture" directions. :mad2: My attempt to replace it this evening is cloaked in failure.

Anyone have advanced ideas for one of these welded-on mofos? I have NO room to work, of course, and about a 15 degree swing for a band wrench. No direct vertical access to the nut on top, which is well rounded now. Barely enough room to get a strap wrench around. Vacuum pump in the way for a ratcheting wrench or other 'fat' box-end. I was thinking about a chain wrench as my next attempt, although it may be pliers and a blowtorch ala marcellus wallace. I ran out of advanced vocabulary and called it a night.


I bent the ish out of my hangar neighbor's strap wrench trying to get this mofo off. I owe him a better wrench, as this chinesium harbor freight special didn't hold up.

I'm trying to imagine how much torque it took to bend the stirrup like that. My calibrated cussing-elbow maxes at about 50# :D

This experience may get me back to Champions.

Anyone have advanced ideas for one of these welded-on mofos?
Big vise grips to filter nut
Oil filter pliers, or if room large channel locks to filter body (filter pliers my go to solution)
The ol' screw driver/drift punched through filter trick. Just be sure you poke it through giving you room to loosen the filter.:rolleyes:
Torch.............................not.
Good luck.
 
Sorry but you just have to keep trying. I find a strap metal wrench near the base of the filter helps. Even a 15 degree movement is good if you can get the thing moving. If not then something drastic like punching a screw driver through the cannister to move it. Otherwise perhaps calling tempest can give you better advise. We mechanics put the oil filter on finger tight then another full rotation puts the filter in the torque range, then torque with a torque wrench. If you can't do that then the 1-11'2 full rotation after you hand tighten it will put you in the range. Then do a leak check after you run the aircraft up for a few minutes. Otherwise, we all have been there and appreciate when people torque it correctly. I suggest you buy a tool that will enable you to torque it in the future, or go to a filter that is shorter. Ask you mechanic about it.

If you are still struggling, these might work.

The last time used one of these I cut a V-belt and wrapped around the crankshaft pulley and wrapped this over the belt, on a 2010 Elantra to loosen the crankshaft pulley bolt.

(Getting it all assembled with one hand was a PITA but the tool worked perfect locking the crankshaft with it and a prybar)

Yeah, that's what I'm thinking. Chain wrench. Crescent makes a narrow-handled one that should fit between my oil cooler and engine mount and allow me a little swinging room. I just need to break the sucker over, then I can go back to finesse and kind words :D

I don't think I put this filter on, but will be very disappointed if it's my own handwriting greeting me. I really hope not. :D
 
If it doesn't budge, force it, if it breaks it needed to be fixed anyway.
 
I love Beechcraft, but this design is some serious BS in general, and the engineer who came up with this combination needs his gonads booted in. oil cooler in foreground, breather line is already removed, engine mount and (behind the elastomeric mount) vacuum pump complete the "no access for you" storm.

It's not obvious from the pic, but the oil filter is about 1/100" too wide to actually clear the oil cooler - engine mount passage. It has to get snaked around behind the mount, which means removing the alternate air tubes... argh.

I am considering moving these turkeys to Challenger lifetime filters out of sourness for this job. Anyone use those things with any success? pireps seem thin on the internet at large.

Can you remove the bolts holding filter adapter to the engine and take the whole affair out to where you can work on it?
 
Success, but not how I planned. :D

Chain wrench didn't fit around the filter can, but now I have a new $50 doodad to menace people with. :D

There was not enough room to maneuver the filter adapter out of the engine mount without hoisting the whole engine (cool idea though, thanks Dan! It got my brain juices flowing)

In the end, it was a better band wrench, a rich, mouth-filling expletive, and 95% hernia-level force combined that got it to break over.. Napa makes one that makes the chinesium one look like a toy. Should you find yourself in the same predicament, I can recommend the Napa 77-3082. It gripped very well and worked in a very confined space to get that millimeter of break-over that was needed.

...and sadly, I discovered my own handwriting on the old filter, so I am that horrible epoxy-making gasket gorilla. Sigh. :mad2: I put the two replacements on dry, hopefully with better results in 25 hours. If not, the challenger "lifetime" filters may feature for the next round.

And you have to do that twice on your airplane. Yikes!
 
Hard to see the logic in Tempest making their "oil-free" seal. On my IO-320-D1A, the filter spins on horizontally, and no matter how much you wipe the mating surface off, a little oil dribbles on there before you can spin the new filter in place...and instant adhesive creation, I suppose. I mean, you've got fresh oil at the ready for your change; not too difficult in grand scheme of things to smear a bit on the rubber seal.

Champions for me. :) I'm liking Tempest spark plugs, though.

Van's was thoughtful enough to provide a firewall recess in the kit to make access easy...I don't mean to rub it in, Schmookeeg! Your filters are a challenge for sure.

You could always try a metric socket. 26 or 27mm is just a bit larger than 1 inch. I use Tempest and just tap the socket on never an issue

More like "the engine manufacturer is not the same as the airframe manufacturer."

Go work on heavy duty trucks for a while and you'll see the same kind of problem over and over again on vehicles designed and built long after everyone had 3d modeling.
 
I spent the better part of a day trying to get a filter unstuck. I had no one to blame but myself, since I put it on. I used every trick I knew of, from combo wrenched to strap wrenches to driving a screwdriver through it (what a mess!). I finally got out the chisels and cut a lip in what was left in order to spin it out. It was quite a struggle.

How do you use those Challenger units? Do you remove and clean the filtering assembly at each oil change, or do you just drain the oil and refill?

From my researches, you change the cartridge inside of the can every 5 years or 1250 hours, and just swap oil otherwise.

I found a few internet threads about them, but more heat than light about their efficacy.

I think they're too new to rely on an opinion from an engine shop

I think it's really a $300 dice throw to try them out and see if they work.

They might cost 300 but the wager is much higher.
 
anyone have documentation on "don't lube the filter ring?" as our A&P advocates a light schmear of Dow Corning DC-4 lube on the new ring ...

a quick google search brings this article up https://www.avweb.com/ownership/no-muss-no-fuss-oil-changing/
which states (in part)

"To prevent sticking of the new filter, prelubricate its gasket not with engine oil (as is usually done), but with Dow Corning DC-4 Compound, applied sparingly but evenly. Unlike engine oil, DC-4 will not break down at high operating temperatures (thus cementing the filter to the pad). Champion specifically approves the use of Dow Corning DC-4 as an “anti-stick” agent for spin-on filters; however, Champion recommends that this compound not be used on the gaskets that accompany take-apart (can/stud-type) filters."

but no cite to reference the "Champion approves Dow Corning DC-4"

From Lycoming https://www.lycoming.com/content/tips-changing-your-spin-oil-filter

"To prevent damage to the converter-plate gasket, the oil-filter gasket should be lubricated with a thin coating of Dow Corning Compound (DC-4) before the filter is installed. The filter should then be installed and hand-tightened until the seating surface makes contact with the lubricated gasket. The filter should then be turned with a torque wrench until a torque of 18-20 foot pounds is reached. The 20-foot pound maximum torque should not be exceeded."
I just found out about the new ones with lube already on the gasket. Thank you for getting me updated. I bought a case of filters at a good price a while back, and just installed the last of them.
The Tempest filter instructions say DO NOT use lubricant OR use DC4 on the filter or mounting pad
 
Never had this issue and I remove mine about 1 time ever 3 to 4 weeks for a 50 hour. Good strong hand tight is all you need.
