Today I had the opportunity to do an oil change on the rear end of my trike. I have a 2007 that was converted to a Viper in 2016. I read the owners manual (off to a good start...) and saw that I would need a total of 38oz of 80W90 GL5 conventional gear oil. So off to the local auto parts place and picked up 2 qts of Castrol conventional gear oil. According to the manual, the rear differential was to get 32oz (so 1 qt ) and the gear case gets 6 oz. I found the fill and drain plug for the rear differential. I also knew that some had problems with the drain bolt not being centered and hard to remove. I got lucky and the drain bolt was right in the middle and a breeze to get to. I finished draining that, put drain bolt back in and filled that with the first bottle.
So now I start trying to find the gear case fill and drain holes. They are not there! As a matter of fact, it appears that I don't even have a gear case??? The drive shaft is connected right up to the rear differential. Am I going crazy or is this just another error I have discovered in the owners manual?
