Really happy to know the project is back on track and to see how things are progressing.
It was a bit of let down when you had frame issues earlier during the build.

Full steam ahead!

Hi Luky 13

Anxious to see developments on your project. You mentioned painting in your last post. Any progress on that? Hope you got those calibration issues sorted.

Sorry for the long intermission ! Blame it on financial year ending

Facing a few issues
1. Alignment of transmission - having trouble using the engine for reference to align
2. Fixture for transmission mount - can only be done once the position is sorted out

Decided to go for Softail B type transmission, the transmission case arrived this week. More once i start to machine adaptor plates for the tranny !

Default Resolution

A run through: The initial plan was to use a pre-1999 style transmission for the build. This creates 2 issues:
1. If you see the pic below reference and alignment for this kind is error prone. I would need to make a "Transmission mounting plate" to the seat it over the rear shocks and at the same time adjust it laterally so that it is totally inline with the engine centre axis. Because the position of the engine front mount is not finalized yet due to other constraints the problem is compounded.

2. The "Transmission mounting plate" bolts could interfere with the shocks. Under driving condition the shocks have a 3~4 degree movement vertically as a function of the shock absorbing action.



The solution: A 2000 style softail transmission case (on the left). Mates directly to the rear of the engine, does not need a "transmission bottom plate", held by the swingarm pivot shaft at the rear fusing the engine and the tranny as one power-train unit.





Although this is a simplistic solution, it creates another problem. We are using a 'A' type twin-cam engine for our build which is 40mm shorter than the 'B' type which is used on Harley softails there is a gap of 40mm between the mating face of the tranny and the motor for which we need to build a 2 plate adapter set.

Finally able to mate the transmission to the engine with intermediate mounting plates, so in short a small mission accomplished.
The engine has been stabalized at the front on the front mount and at the rear on the transmission through the rear swing-arm pivot shaft.

Next target is the front engine mount, very critical to the rest of the build. Waiting for the rubber mount to arrive before starting !

Its unreliastic building a Harley in Bangalore. Great effort.
Work is simply amazing.

Can't you source frame alone like other parts?

@luky_13

A very interesting project.

I've subscribed to the thread and still awaiting updates and pics of the Fatboy on road.

It's been nearly a month, any progress so far?

Default Restart

... coming back from hibernation to restart the build. Sorry for the rather long intermission, took some time to develop and source a few 'hard to find' parts.

Meanwhile we have been up to some really interesting stuff. Putting together a high horsepower Twin cam motor demands we upgrade the bearing setup on the flywheel (rotor side) from the standard cylindrical roller to Timken conical bearing. The Flywheel is technically 'non-rebuildable' (as per the harley service manual) but out in the west a large percentage of Twin cam motors resort to this upgrade before a rebuild for anywhere between $350 ~ $500. At the onset this non-rebuildable crap let our spirits down and sending the flywheel anywhere to US did not make any sense, it would cost us more than $1500 in freight and customs duty alone. Google wasn't of too much help either, most shops do not like to advise or advertise the process as it risks loss of business for them. Having forced ourselves into a corner we had no other option but get our hands dirty!

'THE PATIENT'
Dreamweaver build-off: HD Fatboy-tc88a_timkenconv_2small.jpg

The process involves extraction of the pressed roller bearing 'race', installation of the timken bearing, minimize crankshaft run out and flywheel balancing. The race is pressed over the crankshaft using a heavy tonnage press and there are tools that aftermarket part champions like JIMS provide to remove them, on inquiry we got a quote of $500 (landed) for the tool . This was unacceptable and meant that we had to design and develop the tool in house. I will not go in to the details of that process. At the end of about a week the tool was designed, machined, checked one final time and sent for heat treatment.

For those who are more interested to know the more about Timken conversion there is a nice video on YouTube .

Once the setup to perform this surgery was ready, it was time to make the first cut !

The wedge clamp was installed and clamped, torque 35 ft-lbs. Lube on the screws, wedge and a few other places.

...history !

The whole process took about 15 minutes but for us it was a major feat . The race is out, timken installation ... tomorrow.
