First gear. Is no go

**newfiebullet** · 07-04-2015, 08:47 PM

Just finished building a Yamaha 225dx with a timberwolf swap and on the maiden voyage 1st gear won't engage..just kinda rolls and clicks...2nd to 5th work perfect...clutch is perfect and adjusted perfect shift smooth and easy....what might be the culprit?...this is the smoothest ,cleanest and quietest engine iv ever had and now this...arggg...bent fork? Can get a video tomorrow if it will help.

.
I would pull the cover and look at the shift fork and shift drum and try to shift it into first and see what happens . . also try to rotate the drum by hand to see if it goes into gear . . you need to kick it over while putting it in gear.

I'm gonna check the middle drive tomorrow..if its only first and reverse it may be in there..who knows..i m assuming I'll have to split the case the check/change a fork?

.
the prob is probably in the shift shaft and drum, not inside the case.

Under clutch cover I'm guessing?

**newfiebullet** · 07-06-2015, 08:53 PM

Does anyone know if the shift shaft,forks,drum from a 200er would work? As ha a Dr 225 there as well if that's any good

Do not split the case!! Make that your very last option and I still wouldn't recommend it. Been there screwed that up.

Another guy who is one of the kings of yamahas on here is Muthy. I'm sure he will chime in.

Anyway, to get into reverse you have to put it into first. You said neither reverse nor first works and it clicks in first.

So to me, when you put it into first it sounds like it is clicking in the housing the holds the reverse to 1st and 1st to reverse switch gears (middle drive gear assembly). Those gears allows the switch between 1st and reverse and reverse and 1st when it is in 1st gear only. Pull that cover off and look at the gears. It sounds like they are stripped badly or not aligning /meshing correctly. As mentioned, it is the gears that allow you to switch between reverse and 1st located in the housing circled in red below. If it works I'll take a Budweiser. Nothing fancy

Another note, that isn't even the correct housing. So you know it has been screwed with. The incorrect housing may cause the gears to not align/mesh properly.If the gears look good it may be an incorrect housing causing your problem. Get the correct housing. Here is a link on ebay. It is called a middle drive gear. Hell, it might even have incorrect middle gears. Look at the autozone clamp holding the yoke boot to the middle gear assembly. That gives you another hint. Anyway, You won't know until you take a look. Make sure that you know what year your engine is before swapping out middle gears.

These are what my 2 1985 225dr covers look like: http://www.ebay.com/itm/Yamaha-YTM22...d6d1a3&vxp=mtr

I would investigate the above proceeding. I think if it was the shifter shaft it would do it in all gears. Goodluck.

I don't know about others but I doesn't help me because this is not what I asked you to do. .

**newfiebullet** · 07-06-2015, 09:14 PM

It's a 250 timberwolf motor is why the cover is different..I also blamed the middle drive but if the gears weren't meshing I wouldnt think she would run good from 2nd through 5th...I could be wrong...Barnett sorry it's not what you asked I don't have the engine pulled out yet...I asked about the other motors because I could check em out before I pull mine.haven't been in one of these motors other than middle drive which is why I asked if I had to remove clutch cover side.

**Yamaha3wheeler** · 07-06-2015, 09:27 PM

Ahhh, sorry. You did mention that it is a 250 timberwolf. I overlooked that. If it isn't the middle gears (which I would definitely still check) I don't know and sorry I couldn't be of help. For some reason I'm thinking when my lever was not locked into reverse or 1st correctly it clicked in 1st just like yours. Maybe the lever needs adjusting???? Maybe the back portion of the lever where it screws into the housing isn't correct (not in the correct position) and not aligning the middle gears properly?? did you adjust the reverse to 1st lever??? Move / adjust that lever and see what happens. This is where I would start and I'm almost and I said almost willing to bet that could be your issue. But for the record im not going to bet.

More than likely an external shift locking mechanism.

Some of these guys have had 1000's of motors apart; I'm under a hundred.

Someone will respond and hook u up!!

**newfiebullet** · 07-07-2015, 04:09 AM

Hah thanks guys I used to tear in to honda s in highschool days but the yammys haven't given me a reason yet until now.I appreciate all and any help ...its gonna be Thursday before I can try any headway

...I did adjust the reverse handle many times and I agree that that its nds like the culprit but I tried back and forth revse to 1st sharing it haulib on it to make sure I was locked in.

**newfiebullet** · 07-11-2015, 02:08 PM

Well I'm this far gonna pull the clutches soon check out other side on the shift shaft
