I just finished the ring and piston job and got the motor re-installed and the U Joints and PDS gear replace and now I cant get the engine started. At what appears to be TDC on number one piston , the distributor appears to be pointing about 90 degrees from the position of #1 plug wire. How can I correct this?
 
The process of aligning the shaft and gear can drive you bonkers. You'll need to anticipate the position of the rotor as the gears mesh. Be very careful here. The tabs for the distributor are offset with relation to the pattern on the shaft from the oil pump. If you have it off by 180 degrees and tighten down the distributor, you can crack the hold down flange.
 
Thanks guys. Haven't gotten el_pescador's instructions yet. Tried the site that was referenced last nite and can't get the file to open nor see it from work. Any other way to get the instruction quickly? Hoping I can get the gear beneighth the distributor turned from the top side and not take the motor out again and drop the pan.
 
Edit:
My boo boo.... the 130 is a push rod engine.........

Did not touch the timing belt, camshaft or crank during the rebuild. I did take the oil pump and shaft out along with the distributor and cleaned them and had the distributor checked out at performance shop. Did not see anything in my manual about indexing a counter shaft for the oil pump/distributor.
 
Guys, it's the AQ130 which is the pushrod engine. It doesn't have a timing belt.

The indexing is about position of the distributor once it's installed. Theoretically, the distributor can be in any position as long as you put the plug wires in the right place. From a practical viewpoint, there is limited room to rotate the distributor because of the position of the condensor. Once you line up the rotor to point #1 to TDC, you still need to have enough room to rotate it for timing. You also need to make sure the gear and shaft assembly first fits properly into the oil pump and then into the cam gears.

It's mostly trial and error. Once the engine is at TDC, do a test fit. You can rotate the oil pump from above with a long screwdriver to get the tab on the shaft to slide in. It can fit properly one of two ways. Look at the slots on the gear. These fit with the tabs on the bottom of the distributor but are NOT centered with the shaft. You'll need to look at the distributor to align the tabs on the bottom with the slots in the gear. See where it fits best so that the condenser is on the right.

You may need to lift the oil pump/dist gear assembly and move it one way or the other. If you do, you'll also need to move the oil pump slot just a little as well.

Take your time. You'll most likely need to do this a few times to get it right. Do NOT tighten down the distributor until the tabs and slots are aligned correctly. Can get to be an expensive mistake and you'll get to learn a whole new lesson about distributors that are compatible with this engine, and how much they cost!

Joe, that was my Boo Boo.
You are correct. The 130 is a push rod engine using a gear driven camshaft........ so there would be no timing belt.

I'm sending you another link. I have tested it and it works.

Just noticed this sentance and a little confused. That gear and shaft assembly does come out from the top. The gear meshes with the cam gear and the shaft goes down and engages the oil pump. When you had the engine upside down to disconnect the connnecting rods from the crank, it should have dropped out. If it didn't, and you didn't knock ot out when reinstalling the oil pump, then you got really lucky. If it didn't fall out, I would suspect that it didn't line up with the oil pump ears exactly right. At the very least, it may be pushed up a little if the bottom tab on the shaft isn't in the ears of the oil pump shaft.

The fact that it's not all the way down isn't obvious from the top until you find that the distributor doesn't go all the way down.
 
oh it came out. It's just been awhile since I put it back in and didn't remember if it went in from the top or the up from the bottom. After taking it out again tonite it obvious it went from the top. Lots of parts and processing since then. Will let you know how it goes. heading back out to it.

Thanks for all the help guys!!:D The instructions got me in the ballpark anyway!! Motor is running!!!! will get the timing light on it tomorrow and see where we go from there. Think I just might be taking it to Michigan on vacation later in July.-Near Luddington. Doubt I could have gotten this far without everyone's experience and expertise! Much appreciated!

Tg in Indy
