Re: Just when I thought I understood A timing...
When the marks on the gears are aligned #1 is not supposed to be TDC on compression.
That only happens when the pin thru the hole in the timing cover is in the detent on the gear. Agree with Art and Vince and Dick

Re: Just when I thought I understood A timing...
OK, I found my new crank gear and took a picture of both sides. It actually does make a slight difference if the gear is installed backwards. If backwards the cam timing will be retarded by a couple degrees.
in the correct position the right side of the keyway will line up with the top left of the tooth. When it's flipped over, the right side of the keyway will line up with the right side of the groove on the left of the tooth. Both sides of the gear have a slight recess from the teeth, and the back side is a few thousands more recessed. I just went back to page 4 and looked again at the corrected timing to see how it compared to my left picture, and I agree with Vince that it looks correct, so button it up and run it.

Re: Just when I thought I understood A timing...
Thanks for going to that effort Tom. My plan is to remove the pulley if it isn't too difficult to get off. I have the correct size socket for the nut but no longer have any 3/4 " drive breaker bars. I'll line one up and give it a try. If there is a mark way down under the slinger, that's a stupid place to put it. The gear is probably pretty hard material but I'll try to use a drill. It'd be nice to have the pulley off so I could clean it up.

Re: Just when I thought I understood A timing...
I was talking compression stroke but I think Tom was on exhaust stroke. Not apples with apples. I agree that Art seems to have it right now. It'll run fine.

Re: Just when I thought I understood A timing...
I've got a 3/4" drive breaker bar now, I'll try to remove the pulley. If it's too tough to remove I'll just put it together, put it on the stand and see if it'll run! (how exciting!)
(( yes this is the real Art )) |

You are welcome to use my air impact wrench (600 ft lbs of torque). It will spin it right off.

Re: Just when I thought I understood A timing...
Apologies for the confusion, Art.

Re: Just when I thought I understood A timing...
easy does it, theoretically that nut shouldn't be on there that tight......
there are threads where guys have sheared the shaft.....that is a large 1 3/8 (IIRC) nut attached to a threaded shaft.....basically to give a very large bolt. put the impact on low and let it vibrate some

Re: Just when I thought I understood A timing...
I figure if I can get ratchet nut loose by arm power fine, if not, she goes back together as-is.

Re: Just when I thought I understood A timing...
Well, apparently all of Vince's replies have an expiration date, and they have all expired.
Once again they're all gone. Now we have another mystery to solve. |

Re: Just when I thought I understood A timing...
I could have used this posting a couple weeks ago when I replaced mine. My gear was not marked correctly as the "dimple" was for the timing pin, not the gear alignment with the crank gear. Set it to TDC, and then insert the gear making sure your timing pin lines up with both valves closed and the distributor rotor pointed to cylinder number 1 on the cap.
