The XL series lifts I work on (8000lb) have a wet bellhousing. Take the floorboard off & see if the hydraulic pump is on top of the trans, if it is, then the bellhousing is wet.

The hyd. system has a filter in the tank- I would doubt that the starter remnants got into the hyd pump. What are the symptoms of the hyd system?

I personally have had starter noses break off in the bellhousing. Cleaning out the bellhousing, flushing the hyd oil & replacing the hyd filter was all that was needed- the lift had no lingering symptoms- that was about 1000 hours ago

What would you do with the lift- fix & resell or fix & use?
