K341 Overhaul Measure stuff

[pfrederi 18,689]

K341 is back from the machine shop and since it is sleeting outside started reassembly.  Got a gasket set from I save tractors.  Had a real problem getting the crankshaft end play correct.  The set came with 3 identical spacers plus the gasket. Service manual says use 2 or three spacers then check end play.  had this thing on and off 2 or three times but couldn't get the end play right...too tight or too loose  (one trip on and off was a result of frustration...I put the end plate on upside down...)

 

Dug out some left over spacers from other projects and realized they were much thinner.  The Kohler and Stens are  .007 the I save tractors ones are about .014.  Used a mix and finally got play in spec.

 

Object lesson measure the stuff that is not OEM

Glad you got that figured out Paul.

 

I would even go so far as to say to measure everything. OEM or not. I worked in GM, Ford, Volkswagen, and Chrysler dealers and any Tech that was worth their weight in feathers would measure everything. Every single thing.

Ya know what I do Paul is save a chunk of the old gasket(s), measure it, and use that as a starting point. Sometimes dead on sometimes a little tweaking is required. I usually like to go a coupla .001s on the tight side.

I haven't done one but I would have measured the end play before disassembly and measure the original shims to get a baseline idea.

You been huffing too much freon today Mike?? Thought that's what I suggested!

I 've been on disability for 2 months so I'm having 404a withdrawls!

 

I read your post and thought I gave you a like. Things are a bit foggy. I was up all night installing alarms on my horses in case you get too close to them!

Dealing with end play on VW flat 4's in the past, i've found its best to measure the old stuff but assume it's worn some, then go from there.

 

Squonk, what's an electrician doing messin' with Freon?

 

Being an electrician myself, i find my blend is R12.

We do both refrigeration and electrical. That's why a few of my brain cells are non sensical

The shims being paper do not come off easily when you first pull the End plate. The are mashed together with the gasket and oil soaked.  They shred rather than peel off.  i don't think i could have counted how many there were or how thick they may have been.

Let me first start with saying I’m not trying to bash anyone or any company.

With that said, most if not all, Kohler parts are being manufactured in Taiwan. Some are good and some not so much.

I had a person who procured parts, a rod to be specific, from an after market company. (I won’t mention the name because of liability issues however, it’s been mentioned several times on this forum as a place to procure aftermarket Kohler parts).

The rod was off by .0004 making it from the start at the maximum wear limit. 

Lesson to be learned here is this. You can’t rely on the tolerances from the overseas companies to be correct. The work around to the issue is the get with your machine shop and have them mic the block and crank and tell you the parts you need. Order the parts.

Once you get the parts take them to the machine shop and have them fitted. They can tweak any tolerance issues.

The quality of the aluminum that is utilized in the manufacturing of the overseas parts maybe something left for another day or another post.

At the end of the day what can we do? Short of buying NOS Kohler parts, which are getting very hard to find, we are left with dealing with what we have. Measure twice, turn or bore once and hopefully the metallurgy will be up to the task.

My machine ship insisted that I bring them the new piston/rod so he could ensure they would fit
