Tatx Posted September 18 Report Share Posted September 18 Hello, I just got a sherco st 250 2017 factory from and I want to have the owner's manual to do the maintenance works etc. On the internet I can only find the spare parts. I can also find owner's manuals for models 2016 and 2018 but not for the 2017 one. For example if I want to change gearbox oil, 2016 model uses one tipe and one quantity, and everything is different for 2018 model. Could anyone help me please? Thank you in advance!

lineaway Posted September 18 Report Share Posted September 18 2017 is the year they went to the new clutch? Even Sherco was confused about quantity. Hopefully someone that has one responds. Quote Link to comment Share on other sites More sharing options...
lemur Posted September 18 Report Share Posted September 18 Manual for the 2020 ST250 shows a drain hole plus an inspection or fill plug they tell you to remove to drain the oil. Odds are the plug is at the same height an oil level window would be if it had one. First check would be to measure the quality of oil you drain out and go with roughly the same volume and then see where that fills to relative to the inspection/fill plug hole. Search for "Oil comparative viscosity chart" and you will find a chart that details the relationship between ISO, AGMA, SAE auto and SAE Gear oil viscosity. Personally I use ISO 46 hydraulic oil in all my 2T and 4T wet clutch/transmissions and never have a problem, same oil they recommend for all season excavator and farm tractor applications which use virtually the same type of gears, seals, shift forks and friction plates. ISO 46 viscosity equates to AGMA 1, SAE 20W auto oil, or SAE 75W gear oil. ISO 46 can be purchased from any heavy equipment store in quantity and costs about half the price or less, so you can change it out twice as often. Too much oil in the case can cause clutch slippage problems and robs power, the oil level is relative to the clutch basket, the clutch should never be completely submerged or the plates will not compress because of hydraulic pressure on the inside of the clutch plate friction pack. Your transmission and clutch do not require a multigrade engine oil which is formulated to accommodate cold startups and a much hotter internal operating temperatures.

lineaway Posted September 20 Report Share Posted September 20 Yeah, during the pandemic or whatever caused Sherco to drop all the original dealers worldwide, or so it seems. Not much info left before that. They had plenty of parts diagrams, but not much real info. You are searching for something that really had no real info. My son a a new 2012 and the owners manual was pretty worthless. Our importer RYP was great, but Sherco themselves worthless. Most spanish bikes were that way.

Some times its better to say nothing. Sherco went to a diaphram clutch in 2017. The 2017 owners manual had the 2016 info. Originally the oil volume was 450 ml. Later on they corrected it to 700ml. It was a crap shoot if you ever got the right info. Quote Link to comment Share on other sites More sharing options...
lemur Posted September 21 Report Share Posted September 21 You're right, sometimes it's better to direct the question to the source of an answer and let the reader figure it out from there 👍 https://www.nature.com/articles/s41598-023-43695-6 Quote Link to comment Share on other sites More sharing options...
