I have a 94 Trail Boss 250 2wd that will not go into forward. Reverse works great but forward just clicks but won’t engage. I’ve verified the shift lever is pushing far enough so I believe I have either an engagement “dog” or mating forward gear that are likely bad. I also see a fair amount of metal on the dipstick magnet. But if I ride the machine in reverse the gearbox seems quiet with no other issues I dictated by what I hear. That said I’m in process of pulling the gearbox to see what parts I need. The gearbox has 1341124 as the model number as shown in the photo below but I can’t find any gearbox on eBay or the Polaris parts site that matches that number. Is this 94 model a year that used some special gearbox? My tag on the box even looks different than all the tags on gearboxes I see for sale on eBay. I really want to buy new parts for the ones damaged in my gearbox to fix the one I have but just doing research at this point to see what gearbox I have to know which parts I need. Anyone with experience with this I welcome some advice or direction from what you have learned. Just FYI this machine is new to me but cranks, runs and idles perfect. It’s not beat up and will be a gem when I get this tranny fixed. Thanks.

 

Unfortunately there are no new parts available to fix your machine.
The best chance is to try and contact Power Sports Nation to see if they have anything to fix it.

 

Thanks Red64. I was afraid of that. I don't have the gearbox apart yet but will in the next few days. Only then will I know exactly what I need. From what I can tell using Polaris parts diagrams online, my gearbox forward engagement dog has 2 dogs and so does the mating forward gear. It looks like models in the later 90's have 3 dogs on the engagement and gear. I wonder if either will work in my case and on my original shaft as long as I have the set (2 dog engagement with 2 dog gear or 3 dog engagement with 3 dog gear)?
