CAT C15 ACERT 475hp MXS - low boost

Did you look at the exhaust fins for damage? We didnt get any exhaust readings from your par.

 

Filter is Fleetguard FS 1023 screen type.( no media ) 100 micron 400 gph. with no media to hold water you need to drain every few days more in winter. least restrictive filter for 120 gph head i can find. did alot of looking. for comparison, Cats upgrade 256-8753 is 10 mic 320 gph. this may be a DUH but remember everything below 100 mic will go to sec filter. i know guys running FS 1023 and changing sec filter around 18-20k. this filter is not cheap( 38-40.00 ) but could be used for 2 oil changes, more if your willing to clean it. friend got these at Fleetgaurd on line # 30.00 ea. dont expect a huge change with this filter. mostly will improve throttle response.
Cats max spec on Exh back press is 40 in water and your close at 35 . must be stock Exh. might look at an upgrade in future. Acerts dont like restriction of any kind. hope this helps

 

Looks like a Cat # I have Fleetguard #s either way should come with bracket that mount to head then frame( reduces cracking mounted this way )
in case you or anyone else needs them.
all Fleetguard #s
bracket #256535S
head 3/8 npt 3836095S
1/2 npt 3930618S
7/8 boss o ring 3833198S

 

A suggestion before install of harnesses. where wires go thru back of plug is clearly where oil enters. I wondered after my harness was in about sealing that area up with an epoxy or a type of sealer to prevent oil from entering plug in the future.not sure what product one would use but done right it would not happen again.

 

problem is that oil in plug probably means oil inside wires. oil follows electrical current and have heard of oil making its way to ECM. cut my harness open and there was oil in the wire. not worth the risk in my opinion. oh well couple more years and Ill be doing my harness again but the right way then. I have good contact at Cat tech center and according to him theres been no update to harnesses since Acert was introduced

 

12.7 Detroits used to do the same thing. I changed out a perfectly good looking injector harness that has weeped oil almost all the way back to the ECM.
