Bolens g174 / Iseki tx1510/2160 K3B engine
I have a bolens g174 (tx1500 or 1510)

Was slowly losing power over the last few years but tractor ran good for the most part... started missing a little but at 2000 rpm and above.. checked compression and discovered it to be very low... 205-225 on all 3 cylinders...

Just tore it down to check things out and see what I will need for a rebuild, in see there are lots out there and I'm getting confused...

I see there are lots with sleeves, however i dont think the k3b has sleeves from the factory. Can anyone tell me if there are actually sleeves in it? I can feel no ridge on top or bottom, has a very nice tapered edge so seems like all engine block to me.

Thanks for any insight guys.

They are not sleeved. The Chinese kits have sleeve. It makes me question the quality of the kits. I have a good used KE75 enginefor sale tha would probably be competitive with rebuilding if yours requires machining.

That's what I kinda figured out... I'm not going with a cheap Chinese kit...

I have a buddy that is the parts manager at a large forklift supplier and can order me parts for the k3b directly from mitsubishi. So I'm going to go that route at .010mm over bore... my cylinders arnt terrible just a good scratch in the rear cylinder ( #3 ?)...

Thanks for the reply len!
