G'day Mystyler,
I'm wondering if I should replace the seals? They look good and feel good? I don't have the correct (or any) press to do it but could still get it done. I'm also wondering if the little bit that has corroded away near the bottom seal will present a problem. I don't think that area would be under too much stress? I've circled the area so it is hopefully easier to spot.
Most definitely replace the seals, while it's in bits.
Absolutely no need for a press for this job; all you need is a light hammer; and a pin punch, soft metal drift, or even a piece of wood dowel. I've fitted uncountable numbers of Victa FC seals this way; it's the quickest method, too.
Drift the old seal out, then the new one in.
Lube the new seal's circumference with a drop or two of engine oil. When fitting the new seal, work around the periphery of the seal, with light hammer taps, so the seal stays reasonably straight as it goes in.
It seats against a shoulder in the crankcase bore, so that'll ensure it's perfectly square to the crankshaft axis.
