Had a lot of issues trying to get my 48 B in time. Noticed a lot of play in the distributor and remove it to check gears. No oil in the reservoir and the the gears were chewed. Found a rebuilt DELCO REMY 1111411 (cross reference 1111735) on e-Bay that I picked up. Was just looking for a few tips in terms of re-installing this distributor correctly. Want to make sure I cover all of my bases. Thanks in advance! |

| When you say rebuilt and e-bay in the same sentence makes me tremble. If I were you I would take the plate the points secure to off and make sure the advance works. I would also look at the gears and see what that all looks like as far as lube. |

basically you need to point to open when the motor is at TDC on #1 cylinder.. When the advance kicks in, it will go to the FIRE mark. So you rotate the motor over with your finger over the #1 spark plug hole and note when it is coming up on compression... continue to rotate about 90 degrees until you see the TDC mark in the timing hole ( flywheel mark).... OK, this is where the distributor is about to open the point... turn the distributor shaft until the point starts to open, ( look at the pointer on top and put toward the plug wire you want to be #1) ...then slide the distributor into the hole.. after the teeth engage, rotate the distributor slightly to see that the point is just starting to open.. if it don't open, pull up a couple inches then rotate the dist shaft slightly and reinstall in the next tooth.. Do this a couple times until you get the distributor point just starting to open... then lock the bolt in place.. another test is to rotate the motor around 2 revolutions, then come up to FIRE mark instead of the TDC mark... now you can turn the distributor shaft against the advance springs to the ADVANCE position, and the point should be starting to open.. This will happen when the motor is running, and the centrifugal weights throw outward.

If you can't see the timing marks; remove plugs and place finger over #1 hole. Rotate engine until you feel compression. Insert length of wire, or electrical tie in cylinder until it contact the piston. Rotate engine until piston is at TDC. Install distributor so the rotor is pointing where you want #1 spark plug wire to be. Install cap and the wires (Firing order is 1-2-4-3 Clockwise). Fire the old gal up, run at 1/2 throttle and fine tune the timing by rotating distributor clockwise until it loads up, then rotate it CCW until it loads up again, rotate the distributor 1/2 way between the two points and tighten it down. ------------- What this country needs is more unemployed politicians-and lawyers.

The reason why the mainshaft gear on the Distributor was shot was because the Distributor Oilite bushing was worn out. When the wobble starts, the gear wears. Also as the wobble continues to get worst, the points rub block also wears which drastically changes the dwell on the points, which it turn makes the engine worst as time goes on. When servicing the drive unit itself, remove the three 5/16" bolts, coil bracket and coil, and clean out the old grease. A little Brakekleen does a great job in cleaning out the "muck" in the drive cavity. Refill the drive cavity with Lubriplate No.105. This is a nice creamy lubricant grease that stays in the gears and will last for a loooong time. I use it in our rebuilt Distributor drives we offer. Make sure the Distributor you purchased isn't worn like the one you already have. You'll wind up with the same problems. We offer rebuilt Distributors exchange if interested.....

joemckna, Listen closely to all that is said above. You are very fortunate to have received advice from some of the best mechanics on the Forum. Take good care of my favorite. Good Luck! Bill Long |

I'm also fairly cautious when it comes to rebuilt parts, particularly on e-Bay, but the part was rebuilt completely, and properly. Seller included pics of disassembly, reassembly, as well as pictures of each individual internal part. It was a good buy, and after inspecting it myself, I got a great deal on it. so now worries there. Thx!
