Fitting Timing Cover Oil Seal Tea20

Should the timing cover seal be pressed in or will tapping it in work, I'm worried that tapping it in May damage the cover.
Thanks

Use a piece of pvc pipe or a socket the right size to fit the seal and tap away with a hammer

I tap the seal lightly to get it started,(seal is approx.. 1/16" into bore) then placed a piece of 2" X 4" wood across the inboard side of the cover and a piece of 5/16" T X 1" wide metal strap across the seal. Inserted a section of 1/2" all thread through the 5/16"T X 1" wide metal strap and the 2" X 4" wood, with washer and nut on either side pulled the seal in.
A fine film of BLUE SILCONE sealer was applied to the BORE of the Timing cover. As you pull the seal in if the seal appears to be cocked you can lightly tap the seal peripheral and it shall align itself.


Info I compiled when REPLACING Crank sprocket ,Camsprocket and Timing Chain.
(1) 85 MM Bore Engine:

(2) Front Lip Oil Seal "National /Federal Mogul Lip Seal" # 472164V A SMALL amount of BLUE Silicone was placed around the inside bore of the front timing chain cover before Lip seal was installed:

(3) I installed a repair SLEEVE on the front drive Pulley, make "DURA SLEEVE" # 99175. The sealing area were the LIP SEAL makes contact was slightly grooved. Dura Sleeve specs. 1.745">1.753" Diam. # 68 Rockwell Hardness:

(4) On installation the Governor plunger shall be reseeded tight against the Flyweights and no weights shall be loose or hanging down:

(5) A small amount (only enough to make the surface shiny) of engine oil was added to the shaft of the governor PLUNGER as well as the timing chain:

(6)There are NO timing MARKES on the NEW Sprockets. You may whish to line the timing marks up (facing each other) before you remove the sprockets:

(7)Place the old sprocket (CAM SPROCKET) on top of the new sprockets and accurately scribe the new sprockets as to the timing marks. There are FOUR hols in the hub of the CAM SPROCKET. Keeping turning the old sprocket until the four hols and all teeth line up. These hols are slightly off set. I used several SHOULDERED cap screws to ensure I had the new and old sprockets properly aligned. You may have to flip the old sprocket over...see right up:

(8) It's good practise to measure the thickness of the hub of the old crankshaft sprocket and the new crankshaft sprocket as the teeth on the two sprockets should align for both proper operation and longevity.(there were shims between the old Crankshaft sprocket and the shoulder portion of the crankshaft):
