Default Yanmar maintenance

Hello all you Yanmar guys,

I have a Yanmar 4TN82E-RK in our 83 FC. I know its supposed to be a Perkins. Don't know why the original Perkins was switched out, but the original owner told me it was all new and only had a few hundred hours on it when we bought it.

I start the generator, load it up and run it for about 1 hour once a month and but have not used it too much otherwise. Perhaps a total of 50 hours since the last oil change but, that was over a year ago. The oil on the dip stick is right on the full mark and still looks clean. It all is running well.

Recently, John posted the full service manual and I was just looking at the Maintenance Schedule and if I am reading it right, it calls for oil changes every 150 hours and oil and filter change every 300 hours.

From what I can tell, the BB manual (looking at the one for an 86 FC thinking it had the Yanmar) calls for changes every 100 hours or 6 months. So, based on the 6 months criteria, I'm over due.

Questions:

What grade / kind of Oil should I use?

How much?

What filter should I use?

What about the air cleaner?

Thanks- NH Bill

Bill,

I have the same Yanmar engine. Is yours a 12.5K Kohler also? The spec # on the plate becomes very important when ordering any parts though Kohler.

I can not say for sure the parts numbers will be right for you. But I have

Oil Filter Kohler252834 napa 1334
Fule Filter Kohler 252765 Napa 3390

Hello Michael,

Yes, I do have the Kohler 12.5.

This information helps.

Thanks, Bill

Its time to service my gennie. I looked at the manual and the oil capacity isn't listed in the manual, its conveniently blank. I found this thread, where Bill asked a bunch of questions including how much, but didn't see that particular question answered? Anyone know? Otherwise I'll just buy 5 quarts, hope its enough and measure what comes out....

Markus,

Just went back to check my log. Here's what I got.

6.1 quarts 15-40 Shell Rotilla T.

Does not burn a drop and takes a long time to turn dark.

Thanks Bill. While you were responding I found the 86 FC specs which called for 5 quarts with filter, but of course, didn't specify which KW gennie it was for!

Googling is showing that racor number isn't the filter, its the whole assembly unit. Anyone have the actual filter part number, and what micron it should be?

Tom - thanks. That seems to cross reference to:

NAPA-3208 FLEETGUARD-FS20102 WIX-33208 WANDERLODGE-2274553

I happen to have one of the Napa ones on board, so I'm good for the current service.
