Hey guys, My secondary drive exploded the other day. Pulled out of a light leaving work, was right next to a co-worker so decided to do a wheelie. Brought it up, I think I missed second gear coming down. By the time I got it in gear it felt like I was in 4th. But it didn't want to go anywhere, felt like something was broken for sure. Tried to accelerate but was only met with clunking from the secondary. Coasted to a stop, Tried taking off again in first and could hear it was definitely the secondary. Which I guess is good because I really didn't want to tear the engine out again this winter. I got home and took the secondary off and my thoughts were realized. Its broke.
Looks like I knocked both the dogs off of the secondary gear. There are a couple small marks on the gear on the transmission. But they are all on the inside of the gear by the retaining bolt so it looks ok. Trying to decide how to approach fixing it. Looks like my options are rebuilding mine, or buying a used complete secondary. Buying a new set of gears would cost me $540 for the pair, just for the gears. But only one is bad and it will be more of a pain to swap out the gear on the trany. A used secondary would be much cheaper but will leave me with a mismatched set of bevel gears, And it may be questionable on the durability. I'm kinda wondering if I did this once how long will it be before I break another one.
Any ideas or help would be appreciated. Ohh one last note. There was a bunch of metal stuck to the speedometer sensor when I took it apart. I have had intermittent problems with my speedometer wigging out and reading around 90-120mph when im cruising at 55-60. I read somewhere on here that is caused by metal on the sensor. So i'm pretty sure I have been damaging my secondary for a while and there has been metal floating around in there. If you see your speedo wigging out it may be a symptom of a failing secondary.
