KT 17 series 1 vs II (Pic)

[jbrewer]

Is there enough in this pic to determine if Series I or Series II?

[olds45512]

No. What does the air cleaner say? Do you have the spec number?

[jbrewer]

OK, I'll ask and see if I can get the info. Thanks!

It's got 800 hrs on it. Is that a lot for this kind of engine? Clearly it depends on how it's been maintained I know, but...

I don't think you can tell just from that. Best tell from that photo is the air cleaner. Most of the round ones I've seen are on series IIs, and most of the series I's I've seen have square ones.

I currently own 2 series IIs with square ones, and 1 series II with a round one. Have a series I lined up with a square one.

Best way to know for sure, aside from the serial/spec number of the engine, is to look for the block off plate for the oil filter on the front right of the engine (technically it's the left rear as the engine is mounted backwards in CCs). It will be behind the PTO. That's not really definitive either, but it's about as good as you can get without digging deep.

With the KT-17, it's all about maintenance. A well maintained one should go 1200-1400 hours, or maybe even more.

If it's been abused, it can poop out at any time I guess.

I've posted many times how to tell the difference by looking @ the area by where the dipstick enters the block.

If you like, you can do a search here.
If it has an oil filter or a block off plate it is definitely a series 2 but not all series 2's have a filter or a provision for one.

I thought you could also tell by the oil filler cap. A series one has one that is below the tin and the series 2 has an extension on it that is higher than the muffler tin (?)

I have both styles on my series IIs. Not sure if that’s stock or not.

Not many Series 1 left to know what a lot of hours means. However, those things blew up like popcorn under warranty (and shortly after it expired), my dad saw more than 1 come in the shop. They also caused a lot of folks to turn "green" and never look back. At this point--30 year old engine, I'd say any Series 1 is a roll of the dice.

Two things I have heard on those, stay off hills and banks and ALWAYS check the oil to see if it has gas in it. One of dad's customers caught his engine full of gas twice.

So what you looking at, a 6 or 782? Been a lot on CL lately. Got a friend down east working out a private sale of his right now.

all the series II's I have seen have said so on the head tin or the air cleaner.
regarding what style air cleaner lid, the one in the pic looks like the one on my most recent K341 pick up.... on another note, (yeah I know, not Cub but still applies to a KT engine) the owners manual for one of my other tractors shoes a "cold weather air cleaner kit" for the twins.... and no mention of differentiation between a Series I or Series II being applicable.

The air cleaners, tins, oil fill caps, and serial/model numbers can,
and have been, changed and interchanged/swapped, by previous owners over the years for various reasons.
So it is a crap shoot unless you look @ the area where the dip stick is installed in the block.

There is an angular boss area, where the oil pressure gauge is, or would be installed.
If there is a threaded plug, or sender unit there, it is a series 2.
If a threaded plug is installed, it usually is an allen head, but not always.
If there is a small driven in cup plug installed in the boss area, it is a series 1.

Of course if it has no ignition coil/ breaker points, instead using a magneto, it is a magnum.
