I have a 129 that I probably shouldn't have believed p.o. The clutch was shot the dash is cracked and all of mowing controls and linkage has been removed( that I was aware of)...So first thought was to put an elec. clutch on but how does one drill and tap a crank without removing from engine? Note small drill press clamped in place did a fine job ,There are 4 7/16 bolt holes in block. Sets in the frame nicely...To remove dash,the speed control and steering wheel have to come off.I tried many methods,none moved it.The control handle is alum.I drilled a hole from top down to steel shaft,At the point in about 6 hrs PB did the job of loosening up corrosion enough . I used a pickle fork type tie rod tool and it came off They are splined,there was a set screw in it originally ,it was gone. Splined alum on steel has just got to corrode..The hole can be threaded so it will be covered.....The steering wheel has not budged with PB and a puller after 2 weeks soak....."never give up"
