Installing Engine Internals

I finally decided it was time to start putting stuff in the casing. w00t!

Giving the e50 one more bath before I put it to work. 

Next, I'm going to seal it up today and start the installation of the top end. 

Adding Area For Gasket

We didn't trust that there was enough area available for the gasket to make a good seal where the engine and the cylinder meet. So Bill thought it would be a good idea to add some area to the engine with some J-B Weld. So what the hell it couldn't hurt right.  Here we go.

Bill prepping the weld
We taped off all of the areas we didn't want the weld to get on
and put a piece of tape between the two case halves to prevent
the case from sticking together.

Cutting off the excess with a razor blade

Some soft filing to make flush. 
After we finished the next day I was organizing my work area and realized a piece of the weld came off :(
I think it was due to the very old JB "kwik" weld we used. 

I had to rip the top off to get it open :)
So the next day I went back to Auto Zone and picked up the J-B Weld Stik and redid the side that fell off. 
It worked great, no need to tape anything off. 
Side finished with the stick

Port Matching (Fix)

After visiting the Moped Army, I was told my best bet would be to J-B Weld the hole I created. So I went out and bought some "slow" curring J-B Weld and gave it a shot. 

I used heat shrink to fill in the screw hole trying to prevent the weld from
seeping into the hole. It ended up working really well.

After it dried over night, we scored the weld down the middle and it cracked it open with out a fuss.

Other side
Afterwards i did some more sanding and called it a day.
I hope it holds.

Port Matching e50

I want to start out by saying I know it's not perfect but once i went too deep on one side I didn't want to push my luck, I figured this is better than nothing.
This is for a "Cheapo 70cc Cylinder Kit" from

Install the gasket to mark the area that needs removed.

My markings with the gasket and studs removed
Some of the tools I used. 
The Bad Side
This is where it all went wrong. I guess the gasket outline
method isn't always the best. It looked like i had plenty of
room but I guess I was wrong. I stopped as soon as this
happened. Then I made a visit to the Moped Army to see
what my options were.
The First Side
It went pretty well I did smooth it out a bit more
afterthis picturewas taken.  I used a file and
sand paper for that.

Main Gear Bearings

All went as planned, took off the old bearings with my puller and pressed the new ones on.

Painted sprockets and brake assembly

I painted my rear wheel sprocket, brake assembly and my engine gear sprocket. 
I'm going to reassemble the rear wheel tomorrow after the paint has had time to completely dry
I'm sure it's not going to last long but it's worth a shot.

Installed Wheel Bearings

These went in pretty easily a lot faster then getting the old ones out. I laid the bearings flush and gave it a whack with a rubber malled.  

Bearing 1
Bearing 2
Side note: I noticed I didn't have the bearing in far enough after
I took this picture. Make sure your bearing is pressed in far enough.

Don't forget the spacer between the bearings 

Rebuilding Idle Sprocket

I rebuilt my idle sprocket last night, it went pretty well. I cleaned the bearings, sprocket, and the gear stopper thing. I'm not sure what they are called but it's the little pieces that stops the sprocket from moving backwards. 
bearings, springs, and gear stoppers soaking in carb cleaner

Back side of Idle Sprocket with clean bearings packed in new grease
Once all the bearings are greased up it should be pretty easy to flip the
sprocket over  with out losing any bearings
I'm not sure what these are called but they seem to hold down the
clips that stop the sprocket from moving backwards and the screw cap.
Installing the clip things I was just referring to
and now the 3 ring covers

Adding grease to the screw cap

After that I screwed the cap on (counter clock wise) and tapped it tight then spun it around a couple dozen times and wiped all the excess grease that seeped out.

Engine Bearings Version 2.0

If you recall I attempted to install my crank bearings a couple weeks ago with little success. Every time I started cranking the bearing down it would start to get a little crooked and get stuck. Now with a second pair of hands and a handy Emeralds Peanuts container they went on with no problem.

A preview of our rig

success of  the first bearing.

Snap ring install

Both bearings and seals and clutch bushing
 installed. that went really well. 

Next I'm going to clean the clutch bell and probably replace the springs and continue the engine build

Rear Wheel Bearings


Now that I got that warning out of the way. let me show you some pictures of what happens when you don't listen to my warning. 

I spent a good couple hours trying to bang out these bearings and  I had to finally call in a friend (Thanks Bill) to help me hit it a bit harder. 

This is the bearing still stuck in the wheel. 
If you look closely you can see my stuck punch    

This is what my bearing looked like after I got it out

Here are the two little bastards 
that gave me so much crap

A picture of Bill trying to figure out why they put  plastic/rubber  pieces  on the end of the  bearing spacer. 

Here is the piece i was referring to,  I kinda chipped the right side of  the spacer. I'm not sure if the other side had the rubber plastic caps. I'm going to figure that out today. 

The wheel is ready to be cleaned 
and prepped for the new bearings.

Oh yea, this is a picture of my punch that was stuck in the bearing. I now know why I couldn't pull out the punch. I'm pretty sure it was straight when I put it in there.
