Need help bad. My snow plow truck is down(and it is aboit to snow). 1974 chev 350 eng. i took out the distributor to up grade the ignition (removed points etc placed in electrinc kit) the problem is I cannot get dist. Back in. Have rried everything.
Resorted to start from scratch and set #1 cly to tdc on comp. stroke, align rotor to #1 and slip in dist. No go. It only goes in so far. It has about a full inch or more before it drops fully down? Have followed many examples on internet...no luck. Please help?

Welcome to the site. Since you’re moved the crank, the oil pump slot is not aligned. You’ll need a very long screwdriver or another distributor to set it. An old distributor with a removed cam gear can be used to turn the oil pump.

Thanks.
I read the aticle. Picked up one tip that may help.
I understand the concept. Understand that oil pump shaft slot needs to line up with dist shaft end. My issue is this:
The very bottom of dist shaft is the gear. When I insert dist. The bottom of the gear hits and stops on the very top of the oil pump shaft. I cannot get the oil pump shaft even started into the hole of the gear. Where it needs to be.I have measured this exactly and confirmed where it bottoms out.
When I place long screwdriver onto the oil P. Shaft it wiggles around pretty good. Making it hard to line up? I have inserted the dist and tried everything suggested and that I can think of (probably 20 plus times now). No luck.
Could the oil pump shaft have moved out of place?
All i did origionally is pull out dist (came out easy). Installed an electronic point kit. Then tried to re insert. No go. So I turned crank to tdc on compression to start from scratch????

Remember as the dist gear engages it turns also, so this can cause issues trying to line up the oil pump drive, take that movement into account as you begin to drop the dist in place.

Exact alignment to dropping the distributor is not true. Does that make sense? The oil pump alignment needs to be over a bit. As the distributor drops, the shaft rotates. Using an old distributor without the cam gear works best. I installed a new distributor into an 87 using and old distributor to set the pump slot. Worked great after a few tries. The engine started right up too. Keep trying. It's frustrating. I know. I've done some that took several tries. Use a mirror and light or look down the distributor hole to see better.

If you put a location in your profile, so people know where you are. There might be a member near by that could help you. Just a thought.

Thanks folks...a good forum.
Ok. I really hate to confess to this but I have to come clean.
The reason I could not get the shaft down, is....
I had taken the gear off on the end of the shaft because when installing the new ignitor point kit I had to put a spacsr washer above the gear (a very this washer). So when I put the dist.gear back on...i put it on backwards. Whick puts the gear about an inch off where it needs to be. Yes...i actually did that.
Switched it around and walla! Pretty much popped right in.
I caught this goof up when viewing a video. And noticed the gear on the vid was an inch or so up from the very bottom of shaft. Not on the bottom lole mine!
I guess turning 60 qualifies from brain dead...thanks for the help!

Upside down.
The details will drive you nuts.

How about a pic of your snowplow?
Your 74 is one of the oldest trucks on this board.

Thanks for posting your solution. It will help others not make the same assembly error. Next time, we should ask for pics. A pic would easily point the upside down gear.
