Anybody used a spin-on filter adapter on the NHC-250 Cummins

Guys I was able to get a spin on base cummins part # 3300922S
I need the bolt length and proper o ring to install. Any body have the info? Cummins and fleetguard are a bust.

Bolt is 4.5in long 5/8 tread grade 5

Bolt is 4.5in long 5/8 tread grade 5

Is it 5/8-11 coarse or 5/8-18 fine?
Any idea what diameter square o ring is used to seal the adapter to the engine?

Thank you! Fleetguard suggests LF670 filter.
What works best for you? There are a blooming million filters that cross with the LF670

I only run fleetguard and donaldson filters.

You can run LF670 or P551670 in donaldson, B96 in baldwin

If you want an upgrade you can run a DBL7670 or LF3363 or LF9325. These are all long life filters.

You can generally find Komatsu filters 600-211-1231 for under $10 each on ebay.

After I get my spin on adapter I find out there are two different spin on adapters for the NHC 250. Baldwin has two models. One is longer for the early and shorter for the later engine. Are you familiar with the two sizes?

Baldwin OB-1368 should be the correct adapter as noted on this thread and others on ss.
