Been overhauling and partially restoring an 861-D. The rear seal went out on her in the early Fall so we decided to completely overhaul the engine and give her some lovin that she has been deserving of.
I have had this tractor a few years now and I bought it from a guy who said he had it for over 15 years.
When we split her apart we discovered a few oddities and decided to replace the crank, cam, pretty much everything honestly.
At some point in this old girls life her balancer gears locked up and broke several teeth off the crank shaft. This is where my problem comes in. We replaced the crank and ordered a new balancer assembly but whomever fixed this tractor before us simply took the balancer gears out and ran her without them.
See the pictures below.
The problem is no matter how hard I look I cannot find the right balancer assembly to put back in. If I replace the housing the assembly I have goes into it requires re-boring the crankshaft. All the replacement assemblies do not have the four holes I need and in fact the entire assembly is about 1/16th of an inch wider than the one that was in her.
Obviously I ran her for years without the balancer gears but I cannot find the proper assembly now and no one feels confident to put new gears in the old one. I thought about drilling holes into the replacement assembly but as I said the sizes don't match.
Any ideas or advice on how to proceed? It would be really welcomed at this point.
