pschrauber Posted July 7, 2013 Report Share Posted July 7, 2013 600cc for the gearbox, 300cc for the clutch and between 150 to 180cc for each fork leg. To the quality: good gearbox oil SAE around 75 - 95 works fine, for the clutch SAE 30 or SAE 5 - 10, here ATF work's very good Elf HTX even better. Forks should be SAE 10, I personal use SAE 7,5 being a light rider. Quote Link to comment Share on other sites More sharing options...

pschrauber Posted July 8, 2013 Report Share Posted July 8, 2013 Fur the clutch and primary drive: There can be used SAE 10 - 5 (older recommandations) from the mid seventies or SAE 30 (newer recommandations) from the beginning 80's, in pesonal experience ATF works too very good. (As thinner the oil as easier the clutch will slip). For the gear box where the transmission is situated SAE 75 - 95 works fine, Castrol EPX does the Job really well you can use either SAE 80 - 90 or even SAE 85 - 140 Quote Link to comment Share on other sites More sharing options...

pschrauber Posted December 5, 2023 Report Share Posted December 5, 2023 Yep, but I have figured out with experience and the years it takes a long time until the oil is warmed up and under cold weather conditions it is really thick which can make shifting harder. I now have changed to ELF HTX 740 to all my bikes, from SWM TL NW, Montesa 242, Panda TC 220, Beta TR 34, Yamaha TY and the Bultaco Sherpa to use just that oil to clutch and gearbox.

OK thank you just not sure what oil to put in the gearbox on my sherpa Quote Link to comment Share on other sites More sharing options...
carl ekblom Posted February 13 Report Share Posted February 13 I use HTX740 oil in both gearbox and clutch. I am confident it is very good. Thicker oil does not improve the gearbox or clutch life Quote Link to comment Share on other sites More sharing options...
carl ekblom Posted February 13 Report Share Posted February 13 The volumes needed are a bit exaggerated concerning the 0,6/0,3 rule. I would say: As long a internals are wet it will lubricate Quote Link to comment Share on other sites More sharing options...
