Primary gear nut stuck

[Chip M]

I have a recently purchased 96 banshee and I am doing a rebuild. I have the manual and am to the point of just removing crankcase bolts/nuts. I was able to remove everything except the primary gear nut. I sucked two or three rags through the gear mesh before I decided that I might be doing a bad thing tweaking the shafts apart as it must have been doing. I continued as the manual explained and got to the point explained at start of post. My question is, Is there a reason the primary gear must come off before splitting the case as long as I have no crank and /or rods problem? The original problem was a shifting problem, stuck in second the man told me. I had got that problem resolved but did not like the way it slid from gear to gear after replacing the gearshift shaft. Thanks to all for your help so far through my first banshee rebuild. One more quicky....how do I get to a place to type in the shoutbox??? tnx

as in the gear on the crank? no you can leave it on. but it will need to come off to change crank seals which you should do while it apart. an impact works very well for this and a dab of red loctite is handy upon reassembly.

15 post to use the shoutbox. You are using an impact??

Thx much and I am going to replace all lower end seals. I hope I can figure a good way to get hold of the crankshaft after it is out to get that nut loose. It seemed really tight but I did not try impact. I got scared of dragging all that rag thru the gear mesh between clutch basket and the drive gear. lol.....need more balls I guess

You'll have to use an impact. You can (at your own risk) place a wrench or ratchet extension through both rods while using the impact if needed. I wouldn't do that without an impact.

This is how I take the crank nut off. It may not be right in everyone's eyes, but it works for me. I place a penny (1 cent) where the two gears mate up and let it hold the pressure while hitting it with an impact. Do this before you take anything else apart on the clutch side. It's worked 100% of the time for me and has caused no issues on the parts involved. Do it at your own risk though.
