Just wanted to let others who may be curious know how I made out. I installed the timing cover oil seal on my Breva 1100 and it still leaked. There were two grooves in the crankshaft from the oil seal. The bike has 11k miles.
So I tore it apart again. This time I removed the timing cover too and used 1500 wet dry to smooth out any burrs. I cleaned the area, applied permatex sleeve retainer and gently tapped the sleeve on with a wood mallet. The sleeve part number was Sturdi Sleeve 99085.
In order to remove the installation flange on the sleeve, you must first use something to cut into the installation flange before installing. Then, after the sleeve is tapped into location flex the flange back and forth along the groove. Using needle nosed plyers, twist/roll the flange off like a sardine can. Be sure not to nick the sleeve. I used the 1500 grit again on the sleeve to be sure of a smooth surface. Cleaned and oiled it and the seal too.
After I got it back together, I took it out for a ride 24 hours later, because the permatex sleeve retainer needed time to fully cure. Everything is dry now. Time will tell how it holds up. The sleeve hardness should be better than the crankshaft.
I'll report back in due time for an update.
