A little paint and that socket looks more better!!!!

So I gets the trans out... open the top...looks in there...and uh.... I dont know what I am looking at.
I stuff it in gear and look in there and turn the pulley splines while holding the clutch basket splines... and watch the gears turn... they turn a long way before stopping. and I dont see what is stopping them yet. or why dont the stop sooner, maybe something is broken off, a tab or something.

I have downloaded the baker OD-6 manual, I guess I will study that for a while.

This is where I see all the play.... the 'tooth' moves back and forth in that gap....... like the tooth is too small or the gap too big.??

The only time I have a wee More slop is when the tranny sprocket get's a wee loose and slips a bit on the splines..
Mine are steel over steel, sooo, no damage to speak of but if your trans pulley is aluminum splines over steel Main-shaft splines, .........................

I got the Ultra up on my other lift and checked it out, it measures the same as your numbers there, Frisco.

The pulley on the Baker (BMC) trans was very snug, came off by hand, but had to tugg a little.

I think the reason the 'slop' is different from gear to gear is the gap in those teeth (the wide square ones) in the picture above is different from gear to gear.

I am almost wondering if this trans has always been that way. the BMC was parked for quite a while and I been riding the Ultra. and now I gets on the bmc....and it feels sloppy in comparison.

I got a call out to a couple friends to go look at thier trans and compare slop. and if they let me open up thiers, maybe I can see something that shows me what is wrong with mine.

got a question:

What the heck is that 'compensing' sproket for??? when i got on the throttle...it would just 'ratchet'. I wonder if that added hammering caused the tranny to wear. I am tempted to just weld it solid. or find an engine sproket without that gizmo on there.

I'm sure frisco can be more help than me here,with H.D. trannys. But FYI and/or WIW for now, the "tooth" you pointed out (arrow) is more often refered to as a "dog".

You have a constant mesh trans...meaning that gear "teeth" are always meshed...and what you're showing here is what engages and disengages the gears (on the same partially splined shaft) via the shifter fork moving them side to side and catching the "dog" of one gear in the "gap" of the other...noting the back-cut needed in each.

Without that "gap" it'd be virtually impossible to engage or disengage gears (in the above manner) and I would expect any change in the size of that "gap" to result in easily visual signs of mushrooming or breakage or wear,etc,there...that I'm not seeing any of, in your photo.

Well...that's all I've got to say about that

gotta go now,and see what kind of chocolates are in my box.

Thanks Ken
Since i hadn't been riding the bmc for a while... mostey the Harley..... I almost wonder if what I am calling 'slop' has always been there. I was just so happy to be riding that hot rod I didnt notice...and now I am paying alot more attention to these two bikes. I still dont thing that much play is right.... everyone I know with a bike is out riding so I wont be able to check how much play is in thier bikes for a day or two.

Frisco measured his belt movement, and it is the same as my Harley..at 1/2" in most gears and less in others.

?-> anyone else with a lift got time to check thiers?? that would be cool. (refer back to post #1)

then there is that compensator sproket....I think it has gotta go. it is way too easy to make it spin...which in turns makes a gawd-awfull racket, sounds like the tranny is back there jumping up and down.

maybe that is where my slop is (when riding)...and the travel in the tranny is normal. I'm gonna look closer at the compensator.

unclepsycho · #18 07-26-2009, 06:25 PM

Holy worn out compensator Batman!!!!

Could this be where a lot of 'play' in the drivetraine comes from???

That gap looks way too big to me....................

unclepsycho · #19 07-26-2009, 06:32 PM

Uh OH!!!..... when the wife noticed that I was looking in the parts book... she asked what I was looking for... well I just says.. ''a compensating sprocket''... well she may be blonde, but she has been paying attention, she says a sprocket goes on the motor..so what would make that wear out??? Uh... too much throttle???

So now I gotta go and increase my life insurance and medical, so I will be able to go ride this thing when it is fixed.

and it is only a 100" motor!!!! not even a nice big one like the 127" that is available out there...

Hi Unc

Awhile ago one of the guys asked about the Comp-Sprock and if it can "ratchet", so-to-speak.. He didn't use that term but, if I recall, that's what he was asking about..
At that time I measured 2 of my Comp-Sprock's and determined that if they are torqued down & spaced correctly there is simply NOT enough space for them to go "over" the cam.. I posted that info..
In-other-words,, it literally Cannot "ratchet"..
If yours IS ratcheting then it is prob NOT torqued down correctly or spaced tooo much..
Sometimes the "NUT" will bottom out on the motor shaft too soon..
I've dealt with both..

When that Cam is in the Valley, after torquing, it should be Much closer and the "travel" of the Spring will simply NOT go far enough to allow ratchet..

BTW--- I measured that "slop" on my 120" and it is a chain not a belt,,,, it's all the same "mechanics" though, so-to-speak..

I left the Comp-Sprock on LiL Suction Cups sickle, I put the 127" in it..
It can hole-Shot as easily as the direct drive Belt Pulleys on the 120" and 93" with No probs..
I gotta say, I really don't see that much diff with Either when I hammer on them..
