New Oil Filter for 520H Onan

[Phatboy 565]

Ok guys i saw a post on here about K&N oil filters ,and i always like K&N stuff so when i went to get the stuff for my oil change i askd the guy for the K&N filter with the part number i got off of here,, he looked it up and said it was discontinued,, uugg so i askd him if that number cross referanced to any other good oil filters and he said yes , a Mobil 1, filter ,,Part # M1-102,,  ita a High Efficiency,,High Capacity,, Extended Performance filter...so i got it and it is not as tall as the Onan filter , about 3/4 of a inch shorter,,, but i am sure being a mobile 1 filter it has to be a better filter than the stock one,, so i changed oil using T1 Rotella SAE 30W,, and turned key and started and oil pressure light went out instantly ,,so all is good... Just thought id pass that information on to you guys looking for a real good filter,, a little pricey at $12 bucks but the guy at auto zone said they were real good filters..and worth the money..

That filter crosses to a Napa 1348 which is about 8 bucks. Do yourself self a favor. Next oil change cut that filter open and see if it's really a good filter. You can't get much better than a Napa gold which is actually a Wix. You might be able to save some money next time.

Mike knows....1410 Napa/WIX I believe for the Hydro....don't listen to the guy's at auto zone lest they be members here....check here.... there are guys here that forgot more than what I'll ever know about a 520

I was a Fram dude till Sqounk educated me...

There are two different length filters for the Onan. Sounds like you got the short cross referenced one. It should be fine.

 

Just make sure the one for the Eaton 11 is not an engine filter.

I use NAPA never any trouble. And, my NAPA's only a mile away.

I use NAPA for a lot of supplies.

[Phatboy 565]

Well next changeill definatly use the napa ,, thanks guys like i said im a 520 noob,, and i didnt change the hydro fluid it is marked on filter it was service 8/15/2015,, and oil looks like it was just changed,, so ill wait tell end of summer to change it,, what is the napa filter part # for the hydro filter ? So i can mark it down.. Again thanks ..

Napa 1410 hydro filter

Just FYI NAPA filters are made by Wix. That's why guys on here are suggesting Wix or NAPA. They are correct they are a good filter. Also Hastings is a good filter they are made by the same company that makes Baldwin Filters. Personally I think the Hastings/Balwin are better filters but ease of finding them and cost is a consideration. I use wix on my Wheel Horses and Hastings or Baldwin on are big farm tractors.

I have been using the purolator brand. Hope I am spelling that right. Seems to be a good filter and its also a 1/4 inch taller then the larger onan oil filter and just barely fits. Seems to have very good reviews but I think the napa is just as good.

There were some years of 520's that had a shorter filter. I don't remember which. I had 90 and a 94. Each took a different length of filter.

Purolator filters are fine.  I've been using them for years on all of my OPE and never had an issue and I DO cut them open.  FYI, Quaker State filters from Menards are Purolators with a different logo on them and usually cost $2-4 a piece.  Two years ago I was in a K-mart in Marshall, MI, and came across Purolator Classic and Pure 1 filters for Ford Escorts and Foci for $0.29-1.59 a piece on clearance.  I bought them all and have been using them on everything that has a 3/4-16 thread base.   
Realistically, if we change our filters ever 25-50 hours, any of them will be fine, even the dreaded orange can Fram that has cardboard end caps (I usually buy WIX air and oil and K&N oil filters but I wasn't going to pass up that deal).

I can only speak from my experience with 91-97 520H's.  The earlier models might be just a little different.

Here goes:

Oil filter clearance allows for 4 3/4" filters, and that is with a little bending of some tin. 4 1/2" will fit without "encouragement"

The Fram 3600 that came with one of my first tractors is 4 3/4 inches, and is the absolute limit of what will fit.

I use Wix 51762, and get them by the dozen from fleet supply.  They are the same as NAPA gold 1762.  4 1/2 length.

I believe they are available with a hex nut built into the cap, Wix51764, but I have no experience with it, and do not know if the length of the nut will cause problems.

NAPA 1348 will fit, but it is about 30% smaller than 1764.  It seems to me that the higher volume filter is a better choice.

use 1762 eng. oil filter    use 1410 for auto trans, this is NAPA made by wix for onan p220g

When I have used the shorter Napa filter, the rubber air seal won't stay in.

It might be you need a new seal mine stays in with a 1348.

agree 

 

'standard' filter diameter is 3"

 

some of the newer filters are 2.9" diameter (example:  some Toro 137-5012 which can be sold as the Cummins / Onan 122-0800 or NN10147)

 

but a good gasket / seal should still remain seated when using a slightly smaller diameter filter

I use only Onan 122-0800 or Fleetguard LF-3339 filters on my 520H tractors.  The grommet stays in place and they can easily be removed with a filter socket.  Onan sometimes packages the Fleetguard in their green boxes since they are the same company.  You can find the Fleetguard filters at a fair price by searching online.

[rick 245]

I never lost the grommet when using the longer oil filter.
