NEW ROTELLA RTO-177 FILTER CUT OPEN

[53' Stude]

Another filter for Powerstroke engines from member Beanoil

Surprisingly, it looks good string and all

Seems a bit inconsistent.

Thanks for that. As far as Puro offerings go, it's decent.

Yeah, I would say so

I hate to say it, but the Prime Guard is a nicer looking filter. But this is at least passable.

I dont know what to think of that snot on one end of filter where ADBV was. Pretty disgusting looking

My exact thoughts

 

[A_Spruce]

What would be the point of the string? Is that really enough to prevent a blowout?

I believe Purolator used it for years as "assembly string" and believe these filter applications use it still. Anyone confirm this?

Thank You

 

[Garak]

I think every Rotella filter we've ever seen cut open here has had that assembly string.

The string is a Purolator hallmark. Used to hold the media in place when the potting is done.

 

[A_Spruce]

Thanks for clarification on the string. Seems like a silly thing to hold over from days of old.

I found string in at least one Fram off my Mazda roughly 30 years ago. Corresponding Purolators did not use string then.

Looks fine to me, of course real proof only seen post use. Afaik, Puro has used assembly string on the larger/largest filters manufactured for a very long time. As the Rotella filters seem primarily for diesel application many/most would qualify in that category. Other than purely aesthetic considerations, never seen post use where it caused any functional issue. I find it assuming though as it does seem to put off some folks.

Thanks for c&p.

Jack: you are very welcome

Thanks for the C&P Adam.

Interesting that the seam isn't the widest pleat, that seems unusual...

 

[53' Stude]

You're welcom Robert. Not being biased but I'd buy the Federated filter. Definitely best bang for $$

The string is there to maintain the circular shape as the ends are being set and potted. Believe me, if they felt they could eliminate the string to save 2 cents they would; they most likely ran some QC tests with and without and found there was a statistical difference in not using it.

If this isn't what happened, now I know where I can go for my next job to score some "quick wins" on cost savings

Thanks for C&P Adam! Got another 6k NG7055 fresh off the 18 Forester today for ya. It's so nice being able to use an evacuator and change the filter all on top of the engine! Oil change took about 8 minutes including filter and never had to leave the standing position.

I use a oil extractor also. Except my filter is underneath

Shame, FEDERATED filters see no need to use string; wonder why eh
