Guest dgriff8923 Posted January 9, 2015 Share Posted January 9, 2015 Hey guys. Does anyone have a good recipe for removing manual transmission and differential oil on a ww1 era car? This car is not running yet but soon. Thanks Link to comment Share on other sites More sharing options...
Rusty_OToole Posted January 9, 2015 Share Posted January 9, 2015 I suppose you would unscrew the drain plug, wait for the oil to run out, put the plug back, remove the fill plug and refill. Is this a trick question? Link to comment Share on other sites More sharing options...
PONTIAC1953 Posted January 10, 2015 Share Posted January 10, 2015 well some differential won't have a drain plug, just a fill plug, have to use a suction gun and hose to suck out as much as you can, then refill till full. Link to comment Share on other sites More sharing options...
Larry W Posted January 10, 2015 Share Posted January 10, 2015 Most importantly, be sure to replace the lubricant with the same viscosity and properties of the original lubricant as specified by the manufacturer. Remember, products of today are quite a bit different from what they were back in the WW1 era. Link to comment Share on other sites More sharing options...
DonMicheletti Posted January 10, 2015 Share Posted January 10, 2015 If the differential has no drain plug, you can probably remove 1 bolt from the bottom of the carrier or rear cover. It might take forever.Or.. you can just loosen the rear cover (assuming it has one) and let the oil drain out - can be messy if you arent carefull.

JV Puleo Posted January 10, 2015 Share Posted January 10, 2015 It very likely has no drain plug and no carrier. My 1910 Mitchell is made that way. There is literally no way to drain it. As my car is apart and I'll be going through the rear end, I plan to put a drain plug in but this isn't practical unless its possible to clean everything out afterwards. I'd be tempted to drop the rear end, take it apart and clean everything but you'll almost certainly find that the rear axel bearings are shot.

Rusty_OToole Posted January 10, 2015 Share Posted January 10, 2015 I used to have a BSA motorcycle in which one of the screws securing the cover was the drain plug and another higher up was the level plug. Wonder if the oil would drain out if you removed the lowest bolt in the cover. Link to comment Share on other sites More sharing options...
JV Puleo Posted January 11, 2015 Share Posted January 11, 2015 Rusty, I hope for his sake it is...I'm betting the cover is on the top. For some reason quite a few brass cars have no facility of draining the differential... I've put drain plugs in two or three of them. I suppose that might offend the "purists" but it does let you maintain them. It would be good of the OP told us what sort of car or truck it was... then perhaps we'd have an answer.

DonMicheletti Posted January 11, 2015 Share Posted January 11, 2015 What kind of car and what year? - some important information. Or did I miss that? Link to comment Share on other sites More sharing options...
Rusty_OToole Posted January 12, 2015 Share Posted January 12, 2015 I told you it was a trick question. Link to comment Share on other sites More sharing options...
