Lost Main lift will lift light loads and tilt function is the same will tilt on light loads
SVL-2 will not lift more than 200lbs and tilt function will do the same, even at hi rpm
Sounds like you need the WSM to start with.
But in order for that to happen, you need to know the real model number of what your working on.
The are quite a few SVL-2 to choose from,
SVL65-2, SVL75-2, SVL90-2, SVL95-2, SVL97-2
