Hello all I have a 620 with a Sherman fork lift that I am working on. the left rear axel seal was leaking badly. when I removed the rear wheel I found almost an 1/8 inch of movement in and out and up and down of the axel. I removed the axel to replace the bearing, cup and the seals. When I reassembled everything I still had the same problem. I can tighten things up if I remove most of the shims between the rear housing and the hub but the break shaft jams tight. I hate to do it but I thought if I disassemble everything and put a spacer behind the bearing cup I could get the bearing to tighten up before the brake shaft binds up. Any ideas would be helpful. Thanks Dave
