S&S 96 Cubic
Inch Stroker Rebuild
 |
My Harley. After losing a
lot of weight.
This all got started on a recent trip to
Mexico. You can read about what happened here. |
| Here's what started it all...one
of the roller cam lifters.
The needle bearing rollers in this lifter
failed, and departed for points south. And north. You get the idea.
The bike was making quite a bit of noise by
this time. I had put 400 miles on it by the time I rode it back from
Mexico. |
 |
| After the needle bearing failed,
the roller stopped rolling, which made lots of metal dust. Some of
the dust got into the oil pump. It decided to take a break. That's
when things got really interesting. |
 |
 |
Here's my internist...Victor, of
the Iron Horse cycle shop.
That's my Harley in the background.
Victor gave me a decent price for bringing
the engine back to its original condition (in other words, a rebuild to
stock).
I figured, as long as he's in there, why
not go whole hog?
There will be more to this story as the
parts come in (lots more). But, as you can guess from the title of
this web page, I am not bringing the engine back to stock... |
| Victor showed me that my
alternator was getting close to failing. Look at the insulation on
the output lines. Yep, a new one of those is going in, too. |
 |
 |
Here's what the failed lifter
did to the Screaming Eagle cam. Note the surface on the right
most lobe. |
| Here's what happened when the
metal dust and needle bearing bits got into the oil pump. Note the
abrasions on the inner surface. An S&S oil pump will replace the
stock Harley subassembly. |

This is a cool shot...kind of
neat to see what was flying up and down underneath me during those 48,000
miles I put on the Harley over the last 14 years.
Most of the parts shown here are coming out
and being replaced, including the pistons, the rods, the flywheels,
etc. Even the cases are going to be disassembled, machined to accept
the S&S stroker crankshaft and larger cylinder barrels, and
reassembled with new bearings. Oversized S&S forged pistons are
going in, with a 10.1:1 compression ratio (no more running around on
regular gas). New S&S heads. A new manifold and a
new S&S Super carb. An S&S cam. My days of bopping
around on a 48-hp Harley are over. The horsepower will be
approximately doubled.
My Harley was still running on the original
belt drive, so that's going, too. And as long as the belt's being
replaced, I'm having Victor put in the new sprockets that are geared
higher to give the bike a bit more top end and to cut some of the
vibration at cruising speeds.
Yeah, this is gonna be real
interesting...so keep checking back...there's more to come....lots more to
come...

Here's what the new horsepower
and torque curves should like like! |
 |
And here's a layout of the parts
that are going into my Harley. |
 |
The S&S manifold for my new
HD engine. |
|
Check out this gorgeous
S&S cylinder head. |
 |
 |
And how about this
machined-from-billet piston? These will kick the Harley's
compression ratio up to 10.1:1. |
|
And here's the S&S cam. |
 |
|
My S&S motor being
assembled. The cases are about the only Harley parts left in there.
Isn't it beautiful? |
 |
 |
Another view of the S&S
96-incher coming together. |
|
Here's a closeup of the cam
and one of the roller lifters just above it. |
 |
 |
Here's the finished bike...my
'92 Softail with the S&S 96-inch motor installed. |
 |
I am pleased with the way this
turned out...the bike is a much smoother highway ride with the taller
gearing, and the S&S motor is much more powerful. |
