Sprocket Tube and Axle - Max IV

[Timbo]

I recently lost reverse on one side and after doing some forum research I found that my rear left sprocket Tube and Axle are missing the bolt that runs through the middle of them. I found the bolt on the bottom of the tub. Can I just re-install the bolt and torque it down or is there potentially more damage that will require additional work? I appreciate any insight Thanks!

How'd that make you lose only reverse? pop the bolt back in and tighten it down, no trouble with that so long as it is the right size.

It was definitely not just reverse, but reverse is what made me finally troubleshoot. The other symptoms were that it constantly pulled to the left and right turns were not working very well. I guess it all makes sense now that my back left tire was basically in neutral in all gears. Thank you for the advice on how to fix it!

When trying to install the bolt I am not currently able to line up the two bolt holes (see picture). Any idea how I accomplish this?

Get a pry bar and push the sprocket over. Wiggle it, don't force it.

Or you could use a tapered drift though the hole, you may have to loosen the chain tension if the chain is tight.

Thanks for the help. I have it lined up and am struggling to fit the 7/16 bolt in. Would it be ok to use one size smaller grade 8 bolt or is that not a good idea? Being that this area is under the clutch there is very little room to try and muscle it in there.

try spinning the axle or sprocket 180 degrees, that may help.
its best to use the same size bolt that was in it.

Looking at the picture it looks like the sprocket tube is gawled , try what Jim wrote, if that doesn't work you may have to run a bit through it to clean it up.

I thought I read grade 8 bolts are too hard and break easy.
Is there any truth to this ?

[Timbo]

Here is a previous thread that I found that discusses the bolt grades for the axle/sprockets. It sounds like some members have had success with both grade 5 and 8.

Question for the forum: In order to get more clearance to work on getting the 7/16 bolt back in the axle and sprocket can anyone provide any insight if it's easier to remove the engine or the axle/sprocket? I guess I am looking for the path of least resistance...

I was able to replace the bolt without having to remove anything. Fortunately I was able to tap the bolt in, then I was able to tighten it by placing a ratchet wrench on the nut (threaded end of bolt) and secured it in a tight space facing the rear of the machine, I then used an air ratchet wrench with a 16" extension on the bolt head end facing the front of the machine. I sure hope it holds up. Thank you for all of the great information!

Just saw your last question. Glad that you got it back in without removing anything. Thanks for posting your procedure. That will help others in the future. There are only a few places you can turn the axle tube to allow you to get on the bolt and the nut with a wrench or socket. I think that's always the challenging part.
