First of the Texas Twins, First Build Options

[Puebloswatcop]

On this engine the front oil galley plus is a threaded plug. it is an 8 mm hex. My 74 1.8 engine only has a press in plug at this location, so not sure if someone had this done, or if they changed the plug on later cars. You can see the crud on thee inside of plug. thats after being wiped clean, gonna have to soak it in parts cleaner for awhile to get that gunk off.

After getting everything accessible from the outide removed I separated the case halves once again. most of the bearing halves were still in the case and showed very little and no abnormal wear...yeah.

[Puebloswatcop]

after removing all of the bearing shells and wiping the bearing saddles, they look remakably good as well.

[Puebloswatcop]

The inside of the case is actually amazingly clean, with the exception of the sludge that has accumulated it the sump portion of the case.

[Puebloswatcop]

After looking at the engine cases side by side I have decided to use the '73 1.7 case for the build in this car. It will become a 2056...here starts the engine journey.

[Puebloswatcop]

I had to take a break from the 1st Twin so I could take my grand daughter back to Colorado and pick up the other twin. Somewhere under all that lovely Colorado dust is a 914....

[Puebloswatcop]

My son and grandsons helped me load her onto the trailer. Stupid me forgot to bring the keys, so we had to manhandle the car into the right position on the trailer. But got her on and all tied down. One good rainstorm took care of the carwash. Of course on the way back to Texas all the washing was negated when Google maps failed to tell me it was sending me onto a road that turned into a dirt road for 10 miles.....But she is now in Texas, safe and sound.

Today I was working on the fresh air fan and took a bunch of pictures and in the process I looked at my phone and .....well crap.....Lukily I was able to download the pics I took, but the phone is toast.....

[Puebloswatcop]

Now on to todays progress...I decided to clean and check the operation of the fresh air fan.....UGLY. no one would want to breath the not so "fresh" air coming through this...

[Puebloswatcop]

I tested the motor by hooking it up to a battery and it was a "no go" dead as a door nail.

So to facilitate the removal of the motor and cleaning of the housing, I started
dis-assembly. The cross rod is easy, e clips on each end. Remove the clips and the rod comes right off.

[Puebloswatcop]

The two halves of the unit are held together by a series of ring spring clips. I was a bit hesitant to start prying on them at first, afterall the plastic is 50 years old. But I finally pried one off using a jewelers screwdriver to get it started. Surprisingly the plastic is still pretty sturdy. Then just work each clip off. and the unit opens up, allowing access to the motor and the other workings. The flappers fall right out of their prosective spots. The rubber seals in these were in pretty bad shape.

[Puebloswatcop]

After getting the fan assembly apart, and having limited time, ( had to go pick up an engine in Dallas), I turned my attention to the fresh air box. Whoever the PO had paint the car went crazy and never masked anything so as you can see there was plenty of Ravenna green in the box. (IMG:style_emoticons/default/headbang.gif)

[Puebloswatcop]

I tried scrubbing with a green pad, soap and water and it didn't touch the paint. So after a bit of research on how to remove the paint, without damaging the plastic, I found a recommendation of using finger nail polish remover that contains acetone. I asked the wife if I could borrow some and she kindly handed it over.....So I used 0000 steel wool soaked with nail polish remover and lightly scrubbed the painted areas....

[Puebloswatcop]

After about 20 minutes of gentle rubbing the paint was successfully removed. After the paint was removed I put a coat of plastic treatment on it to "re-hydrate" the plastic...

Tomorrow I will dive into the motor issue and work on cleaning and repairing that and the fan.

Wow, either your shop is way fancier than mine, or you are going to get in trouble for washing car parts in the master bath.

[Puebloswatcop]

To tell the truth Bob, my wife is pretty understanding, but I certainly have gotten on her bad side when she catches me washing parts in the house..... (IMG:style_emoticons/default/chair.gif)

[Puebloswatcop]

So now back to the DEAD motor in the fresh air fan box. It was filthy as was the rest of the system, So first thing was to remove the fan from the cage bracket it is in. There are 4 spring clips that hold it in place. I carefully popped these off, using care not to pry on the cage or motor.

[Puebloswatcop]

In these fans one of the likely culprits in their failure is one of the four resistance coils. There are two on the motor and two on the plug end in the housing...In this case they all looked good and solid.

[Puebloswatcop]

After checking the resistance coils, I moved onto the carbon brushes for the motor. There are two and each is covered under a small retaining clip (yello arrow). These just pop off, but be careful not to launch the spring that is under the clip into unknown parts of the room you are workin in. Then you can see and access the carbon brushes.

[Puebloswatcop]

After removing the spring, if it didn't go flying on its own, remove the spring and gently pull up on the electric lead to the carbon brush. It should move freely in its bore. When they attached them at the factory however, the tail was not long enough to pull it out of the bore. Check to see that it is not too worn. They are about a holf inch long when new. I used calipers to measure the total depth of the bore (outide of the bore) and then the back of the brush to the top of the bore and subtracted that from the first measurement. The wear in this case was negligible. However, one of the brushes was stuck in its bore. So when I tried to pull it back the wire came disconnected from the brush.
