Jr., yes, that would have been best.
Good news is..... the AQ series engines are fairly easy to remove.
You can kill two birds here; install a new rubber cushion ring at the I/B side (or both)......., and glue the fwd seal in place.
You'll be done in no time.
If this engine is first-time-installed, or if the front engine mounts have lost the original height setting, see the OEM initial alignment triangulation procedure (the six flat points).
This is pretty much a one-time-deal!
PDS:
I pre-fill the PDS grease cavity prior to the seals being installed, and while spinning the shaft as to purge air.
When I see grease come through the ball cages, I stop.
That's when the two seals are installed.
No further grease is needed until the first service interval.
As for the fwd seal, what I meant was to somehow "glue" or "stake" this seal so that grease pressure (from a lever-happy mechanic), can't push the fwd seal out. If we lose the fwd seal, no future grease can make it's way through the more important aft bearing.
The aft seal should actually breach from a 100% grease stop.... IOW, the aft seal should not hold grease more so than the fwd seal....., counterintuative to what we'd normally think it should do.
I've actually began cutting a small slit in the lip or drilling a tiny hole in the seal casing of the aft seal.
I've seen too many fwd seals pushed out of the bore.
For servicing in the future, grease these with the engine running and the shaft rotating! Dynamic -vs- Static!
(same with an OMC, Merc or later Volvo Penta Gimbal Bearing, and/or EZ Lube style axle spindles..... spin while we grease!)
