Changing Triglide Transmission Sprocket

[msocko3]

This past winter I changed the transmission sprocket on both my dads 2009 and my 2010 Triglide from the anemic 32 tooth to a 30 tooth HD part number 83595-11. I did a write up and pictures on another forum at the time while the work was in progress. I figure some folks over here at TT may find this information useful so I'm recreating the writeup over here also. Picture of the primary chain before I removed the tensioner.


Zip tied the tensioner in place per the manual, I'm of the school the more zip ties the better. The tensioner wear pad is in pretty good shape. Only thing I don't like is the chain was tighter than it should have been, only had 1/2" of deflection.


This is a picture of the compensator sprocket and ramps. I was interested to see how the sprocket would look. There had been guys seeing some gulling where the ramps run on the sprocket, mine is showing some of this gulling.




Shot of the primary with everything removed.


I like to bag oily parts so they don't get contaminated with dirt which would require disassembly and cleaning. This is the clutch basket which I will break down and inspect the frictions and steels at a later time. I'll also be installing a Screamin Eagle spring to give a little more clamping pressure.


A shot of the poor trike with a lot of parts missing.


Some of the pieces and parts, you couldn't tell by the look of the gas tank I love blue painters tape.


I started by loosening the belt, taking it off the sprocket and removing the lock plate. This is a shot of the plate being taken off and the transmission sprocket locking tool installed.

As some have learned my dad and I are both anal about things sometimes. I couldn't bring myself to use a pipe wrench on the sprocket nut wrench so I figured I'd use a 40" 3/4" drive breaker bar with a 3/4 to 1/2 impact reducer.

Here is my smiling face getting ready to give it a go.


A closer picture of everything lined up and ready to loosen the sprocket nut.


The best laid plans of mice & men, the poor little impact adapter wasn't up to the task I snapped it like a cheap toy


So I tossed being anal out the window and broke out the pipe wrench and a 3' cheater and got that nut off.


Upon installation of the 30 tooth sprocket I discovered the locking tool would not fit.

I ended up grinding some material off to make it fit. My method was a tad medieval vs how Icebite1 ground his to fit.

Pic of my dad doing the dirty deed.


The finished tool. One note.... While digging around the internet this morning I also found JP Cycle sells the sprocket locking tool for $62 which is cheaper than Georges Garage, Jims and Screamin Eagle. Had I known we would had to grind on it I would have bought the cheaper one from JP Cycle.


The modified tool worked like a charm, got the nut tightened to spec and the lock plate installed. To get the required 35 - 45 degrees required I used a 18" pipe wrench with a 2' cheater bar on it. The black lines in the picture are the starting point which was also marked on the socket and a mark for 35 & 45 degrees.

I took some pictures of the socket and pilot that is used to loosen the transmission sprocket nut.

This is a picture of the tool and pilot, the pilot is used to keep the socket square and to protect the threads on the transmission shaft.


The threads the pilot screws onto are the ones the nut that holds the clutch hub screws on to.


Here is a picture of the pilot installed and the socket held beside it. Note the pilot fits pretty snuggly in the socket, as you can see the nut which holds the transmission sprocket on isn't very thick. Given the amount of torque required to remove this nut due to the tightening torque and the high strength thread locker I highly recommend purchasing the tool.


I squared up the rear axle housing and adjusted the belt tension.

I used dial calipers to measure each side of the axle housing at the pinch blocks to get it with in spec. If I remember right spec is .062, I'm with in .008 so I guess I'm pretty close


To set the belt tension I used a tape measure hung off the top of the swing arm and a Harley belt tension tool to get it with in the 3/8 - 7/16.


I use a neat little Craftsman thread chase set to chase all my threads before assembly.


Before installing the inner primary I replaced the seal that runs on the transmission shaft, per the manual I put tape over the transmission shaft so the seal would not be damaged while installing the inner primary.


I also replaced the 5 bolts for the inner primary that have o-rings on them. I know some folks put a dab of silicone on and reuse the old ones, I decided to follow the manual and replace them, they also come with thread lock patch already applied.


It's finally finished.

Got the chain tensioner installed,


All buttoned up and fresh Formula+ added.

I've found the change makes it a lot easier to take off from a start without slipping the clutch quite so much, it also makes 6th gear a much more usable gear. I think Harley did the 09 - 10 MY's a big disservice when they stuck the 32 tooth sprocket on them. Being a large manufacturer they surly test ride the snot out of the new products. I don't know how the folks test riding the prototype Triglides didn't comment on the lackluster performance with the 32 tooth sprocket, they either were blind to the fact or a bunch of yes men.

With the mods M3 and I did to my TG I am now satisfied with its performance. I am a power ( torque ) freak but I am going to leave it alone. A person can always do more. My bride and I do alot of touring and spend alot of time on the interstates. I have no problem geting up to interstate speeds when pulling on. With the mods that were done it is a HOOT to ride.

For what it's worth, I have the needed tool for the sprocked removal....

$ 80.00 shipped

I installed the 30T on my 2010, what a difference...

Hi, just wondering with the 30T what is your top end speed now? It should be less than before but I'm wondering what it is.

 

[Pittsburgh Biker]

I enjoy reading the articles and looking at the pictures however if I ever took my HD apart it would never get put back together. Some guys are mechanics others are lovers.

I second that! My husband could do it, but it would be in his spare time.....NOT!

I'm not sure what my top speed is, I know it will make 100 in short order.

Come on Joan. You know George will do anything you ask of him.

Will be posting a few of my homemade HD "special tools"...they've got a special tool for everything!

what sprocket does the 08 Ultra have installed?

 

[msocko3]

what sprocket does the 08 Ultra have installed?

I'm pretty sure its a 32 tooth.

 

[joelin5386]

Just got an estimate from my local indy here. $1275 I think iI will wait

WHAT???

You don't want that neck snapping acceleration? Blow off all those old, obsolete 32 tooth stone trikes?? Don't want to make full use of 6th gear (I never understood that one, my 6th gear OVERDRIVE works just like it should)

I have an 09, rides great, I'm perfectly happy with it. Wife has an '11. Rides great, we are perfectly happy with it. We both miss our 2 wheelers, but old age, arthritis, and lots of aches and pains pushed us to Tri-Glides.

6th gear isn't overdrive, the 6 speed transmission is a direct drive transmission and 6th is 1.1. Maybe your style of riding is just plodding along at whatever pace your Trike will provide. I can state from experience its no fun trying to run with traffic going 75 mph and every time a fair sized hill comes along you have to down shift to keep from getting mowed over from the guy in back of you.

I don't know why you always go to the racing angle when it comes to modification to the performance of the Triglide, I don't race my Triglide. I'm not interested in racing it, just looking for it to be usable for my wife and I to travel with.

My bad, I misunderstood the message, he quoted me $475 is that better. I figure it will help me pulling away from stops, and pulling a trailer. I understand my mileage will suffer a little, but hell it isn't great now.

 

[Papa Zook]

$475 sounds more like it!

 

[HarleyGirl60174]

I made the same change to my 2010 trike over the winter when I also took out the cat and changed out the muffler cores, etc....., the change in the gear ratio and power was both unbelieveable and immediate. I have no problem now keeping up with the boys on the highways. I recommend anyone who wants more power and a more aggressive shift ratio do this. What an amazing difference!

 

[HarleyGirl60174]

I also forgot to mention I did not see any difference in my gas mileage. It's never been as good as when I was on two wheels but this is my toy so at the end of the day I really don't care

Won't hurt the gas mileage a bit, throughout all my modifications my mileage has always been about the same as it was when it was stock, maybe a touch better. Last year I ran the stock gearing along with SE255 cams and the Fuelmoto Jackpot head pipe, this year I'm running the 30 tooth sprocket and Woods TW555 cams and the fuel mileage is still about the same.

Just got in from riding the machine home from the dealer after they replaced the sprocket ... I was stunned at the difference the 30 tooth sprocket makes ... much better acceleration ... much easier to reach crusing speed and going through the gears ... my trike is a 2010 and I sure wish the jackasses at HD had built the thing right the frist time.

[joelin5386]

Will I need to change the belt also or just the sprocket

 

[rgc]

No new belt needed ... they did replace all the seals as a percaution ...

Another thing you will notice is you don't have to slip the clutch quite as much. ENJOY.

 

[joelin5386]

Sweet, getting it done soon. Thank all of you a lot

 

[Lakeman]

What about my 2005 Ultra Classic/Lehman conversion with the 5 speed transmission. I have only owned it for 3 days and I don't like the gear ratio. I am always down shifting to keep the revs over 2000 RPM, it is just too long legged. From 30 to 60 if on any hill at all I feel it is lugging and I down shift, I don't like that.
