edited for my own stupidity. Out of curiosity though what do you need such a large endmill for?
Well, long story short, before I put the girlfriend's LJ80 back on the road, I need to rebuild the steering arm. It looks like this:
It consists of a brass-bushed casting (No. 21) which pivots around a steel bushing (No. 23). At either end there are oil seals (No. 22) measuring 26x40x5 mm.
The whole thing was siezed up (seriously, I had to beat seven shades of shit out of the bushing to extractate the whoel shebang), so when she turned the wheel, the entire assembly was rotating with the end result being that the bolt (which runs through a couple flanges on the framerail) was rotating and enlarging the hole in the flanges. So, she would turn the wheel, and the steering arm would torque vertically before beginning to rotate. This created a ton of dead space in the wheel's rotation and caused some nasty vibrations to come up through the wheel.
The problem is this: I plan to machine up a new bushing (No. 23), drill and tap the casting for a grease fitting, and put the whole thing back together... but I can't find the seals. The OEM seals (Suzuki PN# 09283-26011 or 09283-26018) are discontinued, and I cannot locate anyone who produces a seal of the same dimensions; the closest I've found are SKF seals measuring 26x40x7 mm. So, the best/fastest/easiest solution I've been able to conjur up is to machine two millimeters out of each end of the casting to allow the taller seals to fit.
PS: This whole steering system is stupid, just for the record.
