My Kohler overhaul

[Rotore]

Well guys it had to rebuild the kohler since it was literally poop.

But i got it stripped down cleaned the block, ordered a new piston, cleaned the head and got a replacement for one since at was also poop, cut the seats, lapped the valves and will get the crank down tommarow hopefully.

I found a replacement piston for it but the original was 3.266 and the replacement is 3.277 and had a chip so i ordered a new one.

The block looks real nice. What did u use on it?

 

[Rotore]

wire wheel and some petrol based cleaning solvent they had in the shop would of been cleaner if i would of power washed it.

Dang, are those hydraulic lifters?

 

[freakboy]

i belive so.

 

[Rotore]

Wsup!!!!!!!!!!

Well i didnt clean the crank since i was freaking out about the pistons. So i went wire wheel crazy on the pistons and measured bore and piston and labeled them.

Also ball honed the cylinders so its smooooooothh.

here are the measurements:
*piston 1: 3.267
*piston 2: 3.267
Bore
cyl. 1: 3.268
cyl. 2: 3.269

But i have a question in the shop manual it sayd the std. bore size for it is 3.270 my bore is under that by .001 and .002 is this normal?

You aren't supposed to wire wheel pistons.

 

[Kaptain Krunch]

If anything the bore should be over what the manual says from wear, did you measure it in a few places to make sure?

 

[Rotore]

it was a soft wire wheel on a battery drill at a low speed with solvent dude the pistons are fine.

If anything the bore should be over what the manual says from wear, did you measure it in a few places to make sure?

nope i just followed the manual 10mm from the top and 10mm from the bottom of the bore. maybe its me screwing up ill measure it again on monday to be sure.

 

[BriggsTwins]

that sounds right, if the engine hasnt been hammered on. gauge block that indicator so you are certain

 

[Rotore]

will do.

Yup, measure it again, although .002 isn't that much. Im not sure what the tolerance is, it may be .002 for the cylinders, and this one just happened to be on the low side.

 

[Rotore]

yea i was sitting there puzzled when i looked up the std bore size since its smaller especially since i honed it but i gues i f'd up.

 

[Kenny_McCormic]

How did you measure it?

 

[Rotore]

How did you measure it?

i measured it as said in the manual dude

 

[freakboy]

With what a harbor freight ruler?

 

[Rotore]

With what a harbor freight ruler?

uhhhh no.

3-4" micrometer for the piston an 2.5" for the bore
