Lagersolut 613 #1 Posted October 27, 2014 I'm tearing down an M10 getting it ready for a rebuild - looking for some tips on cleaning the journal, I read a while back ( can't find it and don't remember ) how to clean it up without scaring it . I'm glad I'm tearing into this , thought I heard a knock, lots of play ( up and down ) on the rod at the crank . Thanks for any tips/suggestions Share this post Link to post Share on other sites
oldredrider 2,547 #2 Posted October 27, 2014 Muriatic acid works well for cleaning the crank pin. Polish with a 600 grit sandpaper to finish if within specs. If not, a regrind is necessary. Share this post Link to post Share on other sites

Lagersolut 613 #4 Posted November 2, 2014 Thanks for the replies guys - got the engine tore down everything stripped off - bearing plate and oil pan loose- head off etc - talked to my machinist, told me he wanted it just like that- short block style together - Napa did one for me last year ( K241 )- this year I found a guy closer in Thomasville PA - Leedy Automotive and machine shop . He said he's been doing these for 40 years - talked me out of the aftermarket rebuilds/piston/ rod kits - said the OEM pistons/rods are a lot more accurate - quoted me 525 for the parts - gasket kit -valves and machine shop work. One thing I learned ( the hard way ) on this thing , Kohler changed the starter set up - starter bolts directly to the bearing plate and is held together by these bolts Got the starter of and the entire back , brushes and springs came apart .....going to be fun getting back together .

Fordiesel69 226 #6 Posted November 3, 2014 Aftermarket parts are still ok, if you machine around them. That is aquire the parts, and machine after. Not the other way. Share this post Link to post Share on other sites
