I'm in need of some unusual advice regarding a specialty adhesive. Here on the farm I use an old Fiat Allis 100C motor grader to keep up the farm roads, as well as grade new pastures if/when needed. My grader is about 40 years old, and Fiat Allis has been out of business for quite a while. Overall the machine is in pretty good shape and the limited amount of use that I put on it makes it hard to justify buying a newer, more expensive grader if I can repair this one for a reasonable cost.
The harmonic balancer on the diesel engine suffered a failure, and replacement parts are basically unavailable. The outer ring of the balancer has a belt pulley built into it, and the rubber insert between the hub and the outer ring has shrunk, allowing the outer ring to become detached from the hug. The rubber is still consistent, and the outer ring is not worn, so it appears as if a combination of inserting some shims to center the outer ring on the hub, coupled with injecting an adhesive between the rubber and the outer ring will solve the problem.
My question is regarding adhesive selection. I need something that will adhere well to both rubber as well as cast steel, and have a bit of flexibility so that the actions of the balancer do not break the adhesive seal.
Any suggestions?
Thx.
