BMW N55 Clutch Alignment Tool - F22, F30, E90, E82

thingiverse

EDIT: I have tested and verified the fitment of the splined version of this tool during my clutch install (see first pic) and it worked perfectly. The round version should also work perfectly. This is a clutch alignment tool for BMWs with the N55 engine (and potentially others that use the GS6 transmission). This should have the same function as the ~$25 BMW part number 83300494649 specialty tool, but I haven't bought one to compare the dimensions. I printed this for my 2015 manual F22 M235i clutch replacement. Print settings: I printed upright (loop at top) with adhesion on and with tree support. I wouldn't recommend printing sideways to avoid layer lines on the rounded clutch-interfacing features. It should work for manual transmission 1 series E82, 2 series F22 / F23, 3 series E90 / E91 / E92 / E93 / F30 / F31, 4 series F32 / F33 / F36, or 5 series F10 / F11 BMWs as long as they have the N55 engine (with ZF GS6 transmission?). It may work for other manual transmission BMWs as well, and I believe all manual N55 cars use the GS6 transmission. Will NOT work for N54 engined cars as their pilot bearings are backwards on the transmission side. It MIGHT work for B58, S58, and S55 engined BMWs as well but I have not tested this. Current dimensions for the round alignment tool are 14.9mm OD for the pilot bearing interface tip and 32.2mm OD for the spline interface. I believe the transmission input shaft specs are as follows: 32.5 x 35 - 26N (32.5mm minor diameter, 35mm major diameter, 26 tooth) EDIT: I added a splined version of the tool as a mashup of all prior designs. One clutch alignment tool to rule them all.
