Kohler Magnum 8

[Daniël Bos]

I've just come home with a little generator with the above mentioned engine. It looks ex-mod and quite well-built. It's drained of fluids though so I wondered if anyone on here knows what oil I should give it. I found an owners manual on 'tinterweb but I cannot make sense of the graph that tells you wich oil:blushing:.

I was told it was a 1.9KVA genset but that seems a bit low for an 8hp engine, thinking 8hp is about 6Kw is about 5Kva so maybe 4Kva with the mechanical losses etc?

Any tips or hints or things I should be aware of, I've never dealt with a kohler before, but have only heard good things about the build quality etc.

 

Any info welcome, thanks

This is the graph, I know the answer is in there, but I'm just not sure!

I think I'd go with 10W-30 mate unless you're expecting a cold winter and are going to be using the unit outdoors regularly right through it. I'd agree the graph isn't very well thought out though!

 

Kohlers are great engines - I used to race mowers for a good few years, and built and raced the first mower fitted with a Kohler - a Command Pro CS12 fitted with the slightly different carb from a CS Hydro 12.75. That engine was brilliant - other members of the club had raised eyebrows over the cost but my guess was that a better quality engine would last longer and so actually work out cheaper in the end - some guys were going through four or five Tecumsehs in a season! All racing mowers have the governers removed so they'll run up way past the normal operating speed - up to about 5000rpm. That engine I fitted is still being raced today which says a lot about it!

 

I also remember a great ebay ad for a big flail mower with a Kohler on it. Seller said "it hasn't been started for ages - but it will - it's a Kohler..." Says it all.
