\"DSC09655\"
\n<\/a>With an old machine like this, you never know what might have happened in the past, so let’s check carefully and proceed.<\/p>\n

<\/p>\n

\"DSC09656\"
\n<\/a>The lower side is a bit rough. I imagined some negative scenarios\u2014like it being loose and fixed with a backing washer\u2014but it turned out fine.<\/p>\n

 <\/p>\n

\"DSC09659\"
\n<\/a>There are burrs flying around, so I’ll clean those up.<\/p>\n

 <\/p>\n

\"DSC09671\"
\n<\/a>It’s always necessary to understand how the standard seal is installed.
\nIf you don’t check how well the seal is working, you’ll often have doubts when adjusting the steering.<\/p>\n

 <\/p>\n

\"DSC09651\"
\n<\/a>The tapered roller has no standard seal relief groove, so the standard seal appears to be ineffective. This installation state is questionable, but setting that aside\u2014<\/p>\n

 <\/p>\n

\"DSC09669\"
\n<\/a>The lower side has a shaft outer diameter of 30 mm, the same as Suzuki, so I thought modern seals might work, but the outer diameter is too large.
\nHonda probably has something available.<\/p>\n

 <\/p>\n

\"DSC09679\"
\n<\/a>I thought modern seals might work on the upper side too, and I found one with good sealing performance, but as you can see in the image, it requires a stepped adjustment nut.<\/p>\n

 <\/p>\n

\"DSC09677\"
\n<\/a>This adjustment nut also has top and bottom sides with relief cuts, so if you stick your neck in carelessly, you’ll be in for a long night. We’ll go with standard.<\/p>\n

 <\/p>\n

\"DSC09674\"
\n<\/a>Measuring won’t improve performance, but I think it’s important to know these things.<\/p>\n

 <\/p>\n

\"DSC09676\"
\n<\/a>A steering that moves smoothly and effortlessly feels really good.<\/p>\n
