Does anyone know what I can use to drive in my new governor to distributor oil seal if anything commercially available for purchase I don’t have access to custom build anything for it thank you in advance
 
there are two different seal, the thickness is different so that will change the depth on how far it is set in
 
Take your new seal with you to a hardware store and see if you can find a PVC coupling (or something similar) that's the right diameter and use it as a tool to drive the seal in place. JMHO Stan
 
Gov shaft seal skf 3719 national 50709
common auto trans shift shaft seal if you have a trans shop by you, most never change em but save them
drive tool for magneto gear I have made several tools for that but sold out right now until I get time to make more

Ok thank you so much and when the seal comes in I’ll get a hold of you with the insertion details
 
Hi,
The seal lip has to face ahead, towards the gear. So the picture you have on the left would face to the rear, towards the distributor.
Be sure the seal lip stays facing ahead, and doesn't turn backwards as it goes through the metal of the drive. Oil the drive, and the seal rubber when installing the seal.
Oil where the seal runs on the drive. The drive should be flat and smooth where the seal rubber runs on it.
Don't hammer directly on a new seal, it can dent the seal, use flat metal, wood, or a seal driver.
Be sure to install the seal to the right depth, or position.

I hope it is more helpful that I took out the governor and distributor
 
Suggestion: while you have the governor off, consider making a punch mark on the front side of the governor gear that corresponds with the punch mark on the rear side. Once you've installed the seal you can't see that punch mark very easily and you need to know where it is when you reinstall the governor.

If you don't have a punch, you can just make a paint mark after cleaning the oil off the forward side.

Thank you sir I will do just that and since this seal is smaller in thickness does anyone happen to know how deep I have to set it to

The original seals were driven in to a depth of 23/32", which put them very close to the magneto drive lugs on the governor. The newer seals are thinner and are driven in deeper by 1/8". The total depth would be 23/32" + 4/32" = 27/32" or approximately 0.84". After installation, check to ensure the seal does not touch the lugs on the governor.
 
Below are pictures from TM Tractor Parts.
The 1st is the governor gear. The IH timing mark is 1 dot, at the left of the gear, at the end of the gear tooth.
The 2nd is the gear that turns the governor gear, the idler gear. The timing mark is 1 dot, at the right of the gear.
The IH timing mark for the governor is on the rear facing side of the gear in the engine.
Don't use the timing marks on the front side of the idler gear to time the governor, those marks are for timing the gears in the engine.
You should turn the engine to number 1 cylinder TDC before removing the governor, so it is easier to time the gear when putting it together.

Also, as an added precaution, place some wax paper over the front of the shaft where you will start to put the seal on. There can be a "nick" on the shaft that can put a small cut in the seal lip. You don't want anything to damage the seal lip. Use plenty of oil on the seal.
