D2Denny Posted October 13, 2022 Share Posted October 13, 2022 Went to change the oil in my G-75. Decided to pull the bottom cover in the pan to clean the screen. Removed cover and found no screen. Looking into the removed cover I see the remains of 4 spot welds. Was the screen detachable or was it welded to the cover? Going to have to pull the pan as the tin cover or shroud at the bottom of the oil pump and pickup tube is cracked. Don't want it to completely fall free and potentially block off the flow to the pump. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70563-end673-in-pan-oil-screen/ Share on other sites More sharing options...

theakerstwo Posted October 15, 2022 Share Posted October 15, 2022 The screen was used when the early engines did not have a full flow oil filter but only a by/pass filter and it was a luberfinner 500.I can not rememeber how the screen was connected to the cover.

D2Denny Posted October 17, 2022 Author Share Posted October 17, 2022 This truck only has a bypass oil filter with a 750 type element in it. So at this point nobody is sure how the screen was installed in the oil sump??
