Governor controller malfunction on my mm55SR. Sticker reads: 140-4938 G/A Cont. 12v RK-0308 Mitsuba Japan Lot No 80223 No hits on internet. Any ideas about chasing down a part or a suitable interchange? Regards, Shaun
Parting Out MM55 Shaun, I saw on craigslist two days ago a fella in Damascus, Oregon who is parting out an MM55. Ad says someone already got the motor but you may want to follow up on this as you know how hard parts are to find. https://portland.craigslist.org/clc/hvo/5522677300.html I'm looking for a 169-1237 Solenoid Kit...do you have one? Jeff
Call your CAT dealer those are CAT part numbers. Can't say if they'll be readily available or not.
Made it to Damascus and picked the boom knuckle, cab and a few miscellaneous parts. No electric or electronics were still available. Cook Equipment in Michigan is parting out a machine, have you checked with them?
