My 25 year old Cat 3535 is leaking oil from the crankshaft oil seal (Pulley-side....non-pulley side is OK). We've changed the oil religiously annually.
How bad a job is it to replace from the OUTSIDE?
If memory serves me correctly...I was able to pull the oil seal on a Cat 623 from the outside using self tapping screws, and pulling it without removing the crankshaft. Can this be done on the 3535? What are the odds that it's just the oil seal, and not also the crank bearing?
