- Tyler Holland, Outboard Specialty Tools, diagnosing a Yamaha F25 slipping out of reverse gear. Carrier removed with OST-0024 Lower Bearing Carrier Puller on a very corroded 2012 gear case. Already removed shift rod and unbolted the lower carrier retaining nuts. Pulling the carrier to inspect pinion/gear set and clutch dog. Found heavy wear on clutch dog and reverse gear leading edges where the two pieces mesh together during reverse shift. This failure is common on this type of gear case, is also very common on larger HP, specifically F150 where this type of damage shows up as gear chatter going into forward and reverse, caused by shifting into gear too slowly

Welcome back Tyler! Thank you for another GREAT video.
Hello! Could I ask you about the pinion under the top of gear in the oldest Yamaha 30 was located flat bearing, but modern motors don't contain this bearing.
And next if pinion gear didn't have top bearing why does the vertical shaft have conical bearing except ballbearing?
Conical bearing shold have pair of counterforce!
But modern motors of 30 hp didn't have counter force for conical bearing!
Please describe what the hell is going on with marketing?
Just need it one time. Can’t justify the cost for a one time on a 40ish year old motor. All things aside awesome looking tool
Stripped the castle nut first try. Forgot they’re made of softer metal. I’ve also found it difficult to find a suitable nut for the application, i believe the threads are M14x1.5. Do you have any recommendations? I see you didn’t have a castle nut on there. Tyia
I've done the same. Are you using a steel nut or the castle nut when using the tool?
@@randykane474 was using castle nut… then i got a hex flange nut from mcmaster carr
Great tool! How about video putting the assembly back together with new clutch dog and reverse gear?
Hey thanks for the video. Does that reverse gear come off of the carrier bearing? If so, do you know the process for removal?
Thanks for your time
The reverse gear and bearing usually are pressed into the bearing carrier, but a few second s of heating the carrier on all sides with a torch and the carrier will usually let go of the bearing. Normally I use a bearing splitter to remove separate the bearing and reverse gear from each other
Can you do a video showing removing the reverse gear?
Any change for a counter revolution gearbox box?
Your shims are probably out of spec. If you don’t install the correct sizes, this will happen again
