WHY I CAN'T BUY FROM COBB CARPET SUPPLY ANYMORE

[Newman]

I had to look up the SN oil classification to see what it meant. What oil should be used in the small engines to prevent catastrophic failure? Does the use of SN oil effect only that specific engine or is there potential problems with all small engines when using automotive grade oils designated SN?

The best oil for an air-cooled TM engine would be Grade SL .

I would use 30W in the summer.

In the winter, a 15W-40 Diesel oil would be the best protection (Grade CH-4).

Both of these oils have additional protective zinc phosphate compounds . . .

to better protect against metal-to-metal contact.

Mikey:
The DC538 is a #56 blower, which has higher lift than either of the two you mentioned.

Id sure like to see one in person.

Agree. If a company makes a mistake they should "at least" act like they care and want to attempt a remedy. That takes a lot of the sting out of the situation. Ran into this same attitude with Interlink. Problems may occur but it is how it is resolved that makes a company get our return business.

I think what he is saying is that you guys (Larry) did'nt offer to do anything. Maybe if you would have called Kohler back when he was having an issue and learned "that they have seen a few 999cc engines with oil dilution issues" you could have assisted him with the problem and at the very least saved him a few bucks and come out looking like a hero instead of a cheapo lol.

Talked at length to my Kohler engine service rep today.

He stated that they have seen a few 999cc engines with oil dilution issues,

that led to premature piston ring and bearing failure.

First symptom was oil blowby, resulting in high oil consumption.

This could have been the case on this TM engine,

if it was operated with 10W30 type SN oil.

Much more likely reason for the main bearing failure,

after 3 years of service.

Oil analysis for metal particles could have determined if this indeed was the case.

Ya and its never what the engine cost to do anything labor and modifications is subjective to how long the job takes and he restated 1103 hours or so. People read and think.

Any of us buy something and it breaks were not happy period.

Get bad service from a restaurant you probably wont go there again and possibly leave a bad review too.

Larry wants to hear the good the bad and the ugly so he can make it better and avoid these problems in the future.

At least I hope thats how he runs his business.

I'm good with my equipment, and I run the shit out of it.

I had a hydramaster for like 10 years, I was on my 4th motor.

1st I replaced just cuz it had a shit load of hrs.
2nd one broke a rod in the 1st 2 years.
3rd I feel I got my hrs out of when the timing gear broke.
4th still in it, but it only had one hard year of use and is a part time machine now.

So that said, 3 years old.. How many hrs? 230? Maybe the engine died of boredom.

That's funny right there.
