the HT i assume?
i shoulda taken pics, i was doing this last night...
one, did you replace or remove the gasket? as a quick trick...i SCAN my cases for gaskets. clean em up, lay em on, cover with dark heavy blanket, scan, cut to profile. use thick paper. like 200gsm+. scanners are cheap nowadays
of course, ive had no ink for a few weeks so i didnt do it this time
change bearings? etc? why exactly was you digging around down there?
but...when you pull it apart this time,
1, check the bearings are free. one of mine had seized(lets say i forgot about the gasket and bearings when i pulled it apart last year and rebuilt it the other day and had to scratch my head for a while
)
2, remove all the SHIMS from the ends of the crank. there is usually two or three on each side.
3, replace crank without shims, tighten case screws. dont put sealant on gasket just yet.
if the shaft slips side to side,dismantle, then re insert one shim only.
repeat if necessary until its just stopped the endplay, adding one shim to alternate ends each time. without clamping on the crank. loose is better here... ie, if you run out of shims, dont stress.
all the bolts are same, bar three...two just under the cylinder that come in from the other side, and one right at the bottom of the case. thems be short ones. but no, they cant interfere with the crank, you just wont get some in if wrong...
