K341S Head

Recommended Posts

Well, I got my engine today but when I went to remove the spark plug I found out the threads were stripped out in the head:(! So, unless there is someway to "fix" it, I need another head. Has anyone got a good head laying around?.Otherwise the engine looks to be in good shape. Dan

Haven't had a lot of luck with heli-coil on air cooled cylinder heads. I use another brand (can't recall the name. Have to check tommorrow in the shop)that uses a threaded insert, rather than a coil. It is knurled at the top. Once you rethread the spark plug hole, you apply loc-tite to the insert and screw it in just a hair below flush with the top of the head. A special flaring punch comes with the kit and you use this punch to flare the top of the insert so the knurls cut into the head to lock the insert. Pat

kit comes with its own drill bit. You drill the hole larger. The kit comes with its own tap. You tap in larger threads. The kit comes with " helicoils " basically a new set of threads that you screw in with the special tool in the kit then screw your plug into that. They look like little springs so they have threads inside and out. I have faith in you . If you can get 10 thumbs to drill and tap a straight hole you can do it no problem. And yes Pat everybody has their preference. We use helicoil on dirt bike heads with no problems so they are the only brand I have tried. We all go with what works best for us.

If you have an automotive machine shop close by, getting a thread insert installed should only be a 20 min job, whether it be Helicoil or even the one Pat mentioned.

Had this same problem last year on a K341. thanks to this site I learned about the helicoil. I found it cheaper to and easier to have the local machine shop do it because they already had the bit. The coil itself was only a few dollars. I got the head surfaced, a new head gasket, the helicoil installed and a new plug for less than the helicoil kit. Don't remember now the cost but I'm pretty sure it was under $30 total.

Found where we talked about this before: http://www.simpletractors.com/club2/topic.asp?ARCHIVE=true&TOPIC_ID=6660&SearchTerms=helicoil http://www.simpletractors.com/club2/topic.asp?ARCHIVE=true&TOPIC_ID=6739&SearchTerms=helicoil Also, reading the links above reminded me of my brother-in-law telling me I should wrap the plug threads with tinfoil like you would teflon tape. Never tried it though. Don't think I will either if this ever happens again. Brent

I had the same problem with my 1965 k341 (from a cub 102)and I had the local lawn mower shop do it for about $10.00 + a new head gasket for another ~$10.00 and it runs great. Not bad for a free tractor!! Good luck JH

Once again what a wealth of knowledge this site commands[:0] Thanks guys and gals. I am going to check out the DIY kits and ask at my local machine shop about having them do it. I'll follow up when the job is done. Dan

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
