hi everybody

i have just purchased a A00-4009 6.7 motor for my motorcycle conversion and i'm having trouble figuring out where i can get a sprocket from. i believe my motorcycle has a 525 chain on it and i measured the keyway width on the motor shaft to be 3/16". I need a 15 tooth sproket but it also needs to fit close to the front motor plate becasue of length issues...I don't know where to look. Anything will be really helpful..

Hello Tim,

Try machine shops and Bearing Sales shops. Most of them carry Browning or
Dodge Power Transmission equipments. These range in all the industrial
pulleys, shelves, drive belts, cog belts, bearings, shafts, clutches,
couplers, taper lock units etc.

Hi,
We got ours here in six different ratios for testing:
http://www.sprocketspecialists.com/
We were referred by Bill Dube' to them and they are
GREAT. They know fitment on most motorcycle brands
and understand chains, cuts, gears, ratios, keyways,
and connectors.
Low prices and just about any info and a variety are
available from them.

Although a big crude, I used a #50 industrial sprocket with a 520 rear
sprocket. The 50 has the same pitch, but is thicker. With a lot of
patience, I removed 1/8" off the thickness with a bench grinder. You'd
only have to remove 1/16" to fit a 525.

I just used the stock sprockets on my motorcycle. I had the front sprocket=
welded to a coupler that fits over my motor shaft. When I needed a new ch=
ain I bought one off of Ebay and it came with an extra front and rear sproc=
ket. You should be able to get the sprocket you are after form an online s=
pecialty store as others have mentioned or on Ebay.

You can buy this sprocket for $5:
http://www.surpluscenter.com/item.asp?UID=2007102311481526&item=1-2124-15-D&catname=

It will probably be a little bit too wide for your chain (it's an
industrial #50)

You can either grind it thinner, or (for a more professional appearance)
take it to a local machine shop and have them cut it on a lathe.
It's a quick and easy job so I wouldn't think it would cost more than
$10-$15. Tell them what it's for and they might even cut you a deal.

Tim,

What is the diameter of the motor shaft? I am guessing that you have a
standard shaft with a key set up. You mention that you have space or
alignment issues to get past so you may have to try several set ups to
get a workable sprocket, or move the motor a little.

The best connection to the motor shaft would be by using a tapered hub
and matching sprocket. When assembled, the hub and sprocket squeeze
together as you tighten down the mounting bolts and put a great deal of
pressure on the shaft. Coupled with a key and keyway, this is a good
way to connect. You have to make sure the set up is assembled properly,
to allow the parts to be loosened and removed later. Typically you
remove the bolts, and insert them in the "removal" locations, and when
rotated the bolts separate the hub from the sprocket and the pressure is
removed from the shaft and everything comes apart. If you have room,
and patience to track down a matching set of parts, this is the way to
go. Here are some quick examples from the web to give some ideas. Keep
in mind that you need to mate back to your motor shaft on one end, and
the 525 chain on the other end, and the two pieces of the hub/sprocket
need to be of the same series so they mate up. Here are some ideas or
examples of some of the pieces:
Martin 1008 is a series of matching parts, but your shaft is likely not
19mm like this one:

QitemZ300068679096QQihZ020QQcategoryZ42924QQrdZ1QQssPageNameZWD1VQQcmdZV
iewItem
E-bay item # 300068679096 if the link does not work.
Here is a matching sprocket from the 1008 series:

Z017QQcategoryZ42924QQrdZ1QQssPageNameZWD1VQQcmdZViewItem
E-bay # 7527493580
This is a 12 tooth sprocket. You mentioned 15 tooth. Most DC motors
need to spin fast for cooling, although you do not want to over speed
and destroy them. Consider the smallest sprocket here to keep the motor
running fast, as a very large rear sprocket (over the common sizes) is
hard to find and expensive. If you need close to 15 teeth, here is a 14
tooth sprocket.

Z017QQcategoryZ42924QQrdZ1QQssPageNameZWD1VQQcmdZViewItem
Item 7527713452 on E-bay.

Notice the 50 in the above part numbers. Chain No. 50 is an ANSI
standard. It most closely resembles 530 motorcycle chain. Your 525
chain is close, very close, except your rollers on your chain are 5/16"
wide, and the 530 and 50 chains use 3/8" wide rollers. A 525 chain on a
50 sprocket will not fit properly. As another poster mentioned, you can
remove some width from the 50 sprocket, or you could replace your chain
and rear sprocket with 530 if available. Below is the data on the
chains and sprockets you are using.
http://www.gizmology.net/sprockets.htm

If you do not have the width to use a tapered bushing set up, you could
find a one piece sprocket that has the correct hub size opening with a
keyway. Typically these use one or two set screws to hold them onto the
shaft.

E-bay # 300084028371

I tried to get set up for a Harley belt style drive for my project but
the motor hub was either too bulky, or too expensive from custom work.
I am going with a chain now due to parts availability.

I have a 6.7" motor with a splined shaft with 13 teeth. I got very
close to using a motorcycle sprocket that was close, but just a tad too
much wiggle. I was going to machine in one area of the shaft for the
keeper to drop into, and that would have been a slick set up without
wasting a lot of space. However, the fit was not tight enough, the hub
area was thin, and I thought that the 13 splines would wear our quickly
or break off. I had a tapered hub machined to fit the shaft.

I have several Nickel plated industrial chains that
are new. I can check the exact specifications on
Thursday if anybody is interested. $15 for
shipping/handling.

We did exactly this on the KillaCycle.

We use #60 industrial taper-lock sprockets machined thinner for 630
motorcycle chain. You can do the same thing with #50 sprockets for
530 motorcycle chain.

The machining is not so easy, however. These sprockets are case
hardened. They are actually harder on the surface than tool steel.
You can turn very slowly and use carbide tools, or rig up a grinder
in the tool post. Once you get though the hard skin, it goes much
easier, but you will need carbide tools.

The case hardening is for wear resistance. Thus, removing it from
one side of the sprocket is not a problem.
