On a 914, that piece doesn't go all the way down to the exhaust. It just sticks out and down, and it led onto the fan shroud by a couple of nuts. (Bolts? I forget!)
There is no other bracket. There is a plate that goes across the front of the alternator and bolts to the front of the fan shroud. ("Front" meaning toward the front of the 914.) The alternator pivot bolt goes through the plate, which has a square hole to hold the carriage bolt in place while you put the nut on the back side. --DD |

Thanks Dave, hard to remember from 2 minutes ago never mind 24 months!

Steve,
The easiest thing to do is acquire one of the alternator adjustment brackets from a 914. |

Thanks on the alt bracket advice guys, turns out the lower bracket was broken, the back half was missing. Group member has one on its way to me.
Spent yesterday mocking things up, checking nuts/bolts, etc. Discovered that the type 4 rocker shaft bolt set I purchased is the wrong size. My "FOR SALE pile is growing...... Maybe will take pics of everything tonight, I really need to sell some of these excess parts. I need to order 8MM. Had a hard time finding this, any advice where? Anyhow, I spent some time doing a final cleaning of the case, as it has sat since machine shop cleaned it up. I also bit the bullet and put the front bearing and gears back on the crankshaft, went well! Used an old single burner hotplate from the camping box. Not too bad overall, think I have everything lined up the right way! Tonight will do a final cleaning of the connecting rods and windage tray as well as the distributor gear and get all the gaskets, o rings, etc lined up for tomorrow night. Attached thumbnail(s) |

Finished reassembling the Fan housing tonight, got the alternator attached and the fan housing resealed. Practiced with the Curil K. Thanks to Bruce Stone for a new lower ALT Bracket & fan flap.

I assembled the short block today (more details in #770 thread)
I went through the Reinz kit and have a few questions Picture 1 is the drain plug, not sure which of the silver gaskets go with it. The one in the center is thick and solid, the one on the right is softer. I doubt the copper goes with it. Where do the other two go? Picture 2 is a collection of two medium o rings, and a thin black. NO idea where they go. My guess on the small is for the distributor shaft, but no idea on the larger one. The remaining pics show what gaskets I matched with what. 3 Is flywheel o ring 4 is the large pressure relief piston |

Where do the other two go? ... The hollow aluminum one, center bottom, is for the drain plug. The flat aluminum one might go on the oil temp sender. |

Thanks Chris, I figured one of them was for the distributor. I already replaced the o ring on the oil pickup tube.
Still not sure what the large black/thin o ring is for. I assumed the hollow gasket was for the drain plug as the one I pulled off the plug on dissasembly was soft alum. Top left is for the oil pickup tube inside the crankcase. Lower left is for the distributor. |

There is a groove inside the end of the flywheel that mates with the crankshaft. This 'O' ring is fitted in there.
Good Luck |

I think I already located the fly wheel O ring,is thicker and dark gray. This is thinner, a bit larger. I set the flywheel O ring with the locking plate in pic 3. The O ring I am still looking to identify is black in the pic with the two smaller black o rings (distributor and chimney o rings).
I was able to identify the other small black o ring, it is for the breather chimney. I also looked at my sensors, and all came with the gaskets so the only one left to identify is the large thin black. Thanks for the help guys. Couldn't do this without your help. Attached image(s) |

Still not sure what the large black/thin o ring is for. Top left is for the oil pickup tube inside the crankcase. Lower left is for the distributor. It's the oil pump seal. When you take the oil pump apart, you'll see it selling the 2 halfs. |

Ah, thanks that makes sense. I am not using the stock pump. Great, thanks I can sleep well tonight!

'cue sinister music'
I'm almost ready to take on the 'valvetrain' geometry nightmare. I'm hoping to borrow a dial gauge and mount from a local 914 guy this weekend, and I'm a bit nervous. (IMG:style_emoticons/default/drooley.gif) I've tried to work through Jakes 8 page instructions but it is overwhelming. Anybody have a laymans guide? AKA as accurate but simpler? Not a ding on the article, but my ability to concentrate ;-) Because this is my first time doing this and I know there will be a LOT of turning turning turning, I'm wondering if I just put a piston in cyls 1 & 2 without rings, then mock up the jugs with spacer and snug up the heads if this will make the job easier and be BETTER for the rings and cyls. They are the Keith black floating wrist pins so this is an easy task.

They are the Keith black floating wrist pins so this is an easy task. Also realized that the timing mark is way before TDC..... The true TDC is about 26.5 degrees after. So I'm scratching my head and then open some books to discover that the 'TIMING MARK' IS 27 degrees before TDC.... Everything is mating up nicely and I confirmed that BOTH valves are completely closed when at TDC. |

There should be a mark on the FW that you use as true TDC #1.
The one on the fan is the 27 deg BTDC used for timing at 3500 RPM (for FI). With my carbs I use closer to 34 degrees. And did you measure the cam lobes before installing the cam? |

Did you get your dial gauge set up? Annapolis is a haul but you can use mine over the holidays.
I might have other stuff too..... 443-994-6 four six zero Mike- |
