RE350WD/CO Posted March 26, 2013 Share Posted March 26, 2013 Hi All Can anyone confirm the recommended oil for gearbox on my 1942 RE WD/CO? I note on the Hitchcocks site they mention RENOLIT EP00 for four speed 'boxes. Thanks Vince. Quote Link to comment Share on other sites More sharing options...
Ron Posted March 26, 2013 Share Posted March 26, 2013 I've used monograde SAE 50 in my 43 CO gearbox for years. Ron Quote Link to comment Share on other sites More sharing options...

exlandieman Posted March 26, 2013 Share Posted March 26, 2013 (edited) I'd love to know what the `correct` equivalent oil is also, as our mil xref books at work dont have any of the wdco milspec oils in them. although i think the manual says castrol XL for engine and XXL for box. Ill check when i get home from work. Chris Edited March 26, 2013 by exlandieman Quote Link to comment Share on other sites More sharing options...
Ron Posted March 27, 2013 Share Posted March 27, 2013 Definitely do NOT use EP gear oils in these boxes! The additives in 'Extreme Pressure' oils have a detrimental effect on bronze bushings. Most of these bikes use ordinary engine oil. With the exception of Burman boxes which require semi fluid grease. Ron Quote Link to comment Share on other sites More sharing options...

Hoseman Posted March 27, 2013 Share Posted March 27, 2013 Your EP00 oil is actually a semi fluid grease used in auto lube systems on large plant. It can be used as a gear oil and only comes in 12.5 KG tubs. I have the correct full spec if you need it, but I dont know what effects a mopdern grease / oil will have on your older box as mentioned previous!

wdbikemad Posted March 29, 2013 Share Posted March 29, 2013 Good old engine oil is fine in these old low-tech, low speed simple 'boxes.........Burman boxes, as fitted to Matchless, Ariel and some WD/COs do specify grease, topped up with engine oil, but the modern semi-fluid stuff is a better combination as traditional grease tends to get thrown into corners and stays there..........you can get tubs of the semi-fluid from several of the classic oil suppliers in small tubs, often a litre in size.........I had heard that 16H's and Big 4's also specified grease in the 'box but haven't looked at the manuals for ages.....
