K341

[Lagersolut 613]

Looking for some advice and numbers - just picked up a 416-8 right off the bat I twisted a bolt head off going in to fix a leak ( no gasket ) . It's a threaded exhaust port ideas on going out of the threads or getting the bolt out ?....I have easy outs but have my doubts they'll turn it.

Also I'd like to clean the top end looking for the torque values and tightening sequence reinstalling the head .

Might try welding a nut on the end of that stud.  

As a by product, the heat from the process may help to release any rust from the threads.

It broke off almost flush with the block ..

 

I no sooner had the 1/2 inch open end on it ...pop

Should be able to still tig one onto it though...then back it out.

Head Torque and pattern are in the manual

 

Clean out the threads with a wire brush and use pipe fittings for exhaust.

The only other thing you can do if your unable to weld a nut on it is to drill it out. Level off the broken end of you can with a grinder or file, center punch it and start small and keep increasing the drill size. Also my local hardware store sells left hand drill bits. If you get one of them near the end it may back out. 

Chase the threads with a tap. 

OR just thread pipe directly into the block and don’t use the flange mount.

Thanks 

 

Yea I think the easy thing to do is just pipe it out .

I thought all the WH K341s had a pipe that the muffler connected to.

Found this NOS Kohler muffler with 1 1/4 inch NTP threads ...

The K341s for WH all used a reduction fitting from Block to muffler pipe  1-1/4 to 1"

I agree with welding a nut on the end of

the stud . Ive done it countless times

with great results. Then l would chase the

threads and clean them up,

Item description says muffler is 1 1/4 going in -  would I need to reduce it down to 1" at the block and muffler for the back pressure ?

I'm probably going the pipe route - I'd like to get the stud out but the one thing I don't have is a welder - I'd have to haul it somewhere to do it .
