dayradebaugh Posted June 23, 2021 Share Posted June 23, 2021 I have a B81-SX with what I believe to be a 237 Maxidyne. The engine number is 239GB5354. The dipstick in the engine is obviously for some other engine, because it reads way Overfull when I add 32 qts oil. Any suggestions about where I might find the correct dispstick? If this is truly a 237 Maxidyne, I believe they came with 2 different sizes of oil pans.

mrsmackpaul Posted June 23, 2021 Share Posted June 23, 2021 The size of the oil pan wont make any difference to how the dipstick reads It's depth is measured off the bottom of the block not the bottom of the sump Paul Quote Link to comment https://www.bigmacktrucks.com/topic/67114-dipstick-for-237-mack/#findComment-475712 Share on other sites More sharing options...
dayradebaugh Posted June 23, 2021 Author Share Posted June 23, 2021 Would you happen to know if there is a website where you can check your engine number and find a parts list?

dayradebaugh Posted June 23, 2021 Author Share Posted June 23, 2021 From what little I can find on the 'Net, the number I supplied above does not look right. Where would I find the engine number on a 237-vintage engine?

mechmagcn Posted June 25, 2021 Share Posted June 25, 2021 There should be a serial plate on the block behind the injection pump.

dayradebaugh Posted June 26, 2021 Author Share Posted June 26, 2021 I will check the numbers on the engine next week. Will be looking for ENDT 675, making it a Maxidyne. I will also check the number of spin-on filters. If there are 2, it has the smaller oil pan, which should require about 32 qts. If it has 3, it has the larger pan and would need 56 qts. (See Does anyone have a proper dipstick for a 237 Maxidyne they'd be willing to sell? If all this reasoning is correct, I think it is likely that it would be the smaller pan version.
