There's always a po' man's shortcut. 914's are famous for it.
Usually a flywheel that is that worn on the sealing surface has other wear issues on the clutch surface.
I've been broker' than broke. I understand. I really do. But, penny wise pound foolish is also a lesson I've learned from the school of hard knocks!
It seems to me that three new failure modes have been added.
1) Eventual weepage between the sleeve and the flywheel. Tech sheet says: Pressure seal up to 50 psi: Suitable
for higher-pressure sealing applications; typical industrial shaft seals can handle only up to 5 or 10 psi. Should be OK. Won't have a gusher but I think weepage would still be a risk.
2) The added diameter of the sleeve will pre-load the RMS lip more and may accelerate the seal wear.
3) Position of the seal and the sleeve need to be set properly at install to allow for crank end play and the final at rest postion of the RMS such that the sleeve is always under the seal.
SKF is a decent company and probably has some testing behind these but I suspect they are intended for industrial maintenance scenarios where keeping equipment up and running is sometimes the critical task while proper replacement parts are ordered and then scheduled maintenance is done at a convenient time.
Any follow up on how this holds up over time would be cool! Always willing to learn if there is a better way.
