I'm in the process of installing a reverse chaincase on my 95 XLT special. I'm replacing all the driveshaft and jackshaft bearings with new ones. Should I remove the seals on the chaincase side of the chaincase bearings so they get a good supply of Chaincase oil, or am I better off leaving the seals on them so the bearings don't get any possible metal shavings from gear/chain wear. The chaincase that was on the sled had the seals removed and the reverse chaincase I bought used has the seals on the bearings. New bearings are going into the chaincase.
