Yeah, I did see quite a few but I guess all were turned to the side where it wasn’t showing a fire ring. Do you fellows reckon most of them do have the fire ring. I would hate to order one and it not have the ring… Maybe I’m over thinking… 1 Share this post Link to post Share on other sites

Horse Newbie 7,051 #231 Posted October 17, 2023 (edited) So the service manual says to use a piece of wood or a plastic putty knife to scrape the carbon off the piston and top of the block. I have been cautioned about using a steel wire brush as it may leave steel bristles that may get down in the bore and damage the cylinder wall. I was told maybe use a brass brush as the bristles are not as prone to break off. I will use a brush to clean the head as there will be no danger of bristles getting into the bore. Then sand the head on a granite or glass surface… How do youse guys do it ? Edited October 17, 2023 by Horse Newbie 3 Share this post Link to post Share on other sites
ebinmaine 67,257 #232 Posted October 17, 2023 You're headed the right way. We have a particular piece of known flat steel set aside for hand planing the heads. Hand planing is VERY time consuming sometimes and ALWAYS worth it. 1 1 Share this post Link to post Share on other sites

ebinmaine 67,257 #236 Posted October 17, 2023 Wax on, wax off is actually pretty close. We normally will do about 30 to 50 swipes. Turn the cylinder head 90⁰. Repeat. Repeat. Repeat. We've done quite a few. We start with 120 to 150 grit but we have experience in what to look for. You should probably start with 150 to 180 grit. Go to 240 or 280. Go to 320 or so. Then finish off with a few minutes at 400 grit. Your base piece MUST BE FLAT I can't emphasize that too much. Some folks use wet sanding. We don't. But we keep the paper dust free by wiping or blowing it off between turns of the cylinder head. 1 Share this post Link to post Share on other sites
Horse Newbie 7,051 #237 Posted October 18, 2023 (edited) I was looking around on the internet for parts… points and condenser… I saw this… My serial number on my K341 is 7465208. A note says to install a new push rod on engines with a serial number below 13007371. Have you guys ever heard of this ? Guess I will have to check the manual… Edited October 18, 2023 by Horse Newbie 1 Share this post Link to post Share on other sites

Seems the older (prior to 1983) points push rods were aluminum and wore down over time. If it is not worn below 1.50" length and 0.84" diameter you should be able to use the old one. When Installing 47 150 03-S breaker points on engines below Serial #13007371 (Early 1983 production), always use new push rod 41 411 01-S The minimum length of Kohler engine models K90/K91, K241, K301, K321, K341, K361, K482, K532 and K582 ignition points pushrod is 1.500" and maximum length is 1.550" (new) Used pushrod to be no less than .184" in diameter and 1.500" in length 4 1 Share this post Link to post Share on other sites

Horse Newbie 7,051 #245 Posted October 21, 2023 (edited) So today I renewed my supporter status for another 2 years. That got my head right to work on the decarboning of the head on the K341. Last night I placed an order to isavetractors for: 1. Head gasket (with fire ring) 2. Points cover gasket 3. Breather cover gasket 4. Oil pan gasket 5. Spark plug 6. Points and condenser 7. Points push rod When I read the service manual, I read- clean the combustion chamber with a piece of wood or a plastic scraper. What it said was clean the head and combustion chamber with a piece of wood or plastic scraper. What I did… Cleaned the head with a brass brush, sandpaper, and very gently with a putty knife.After I got the inside part of the head as clean as I could I got a piece of granite and taped some 180 grit sandpaper to it. The I made fifty strokes in one back and forth direction, rotate 90 degrees, 50 strokes, rotate, repeat. I did this until I got down to a smooth finish. Then I switched to 400 grit and did the same. After that I cleaned the top of the piston and valves with a plastic scraper, and vacuumed it good… anything else you guys would do ? What do you think… good enough ?

Horse Newbie 7,051 #247 Posted October 23, 2023 Today I took a little road trip to @kpinnc’s stables and carried the K341 with me to remove the balance gears. @Lee1977 (Don) dropped by too. The balance gears had a little slop in them but Kevin said they weren’t real bad. I wanted them out regardless. We also cleaned the valve stems up and lapped the valves. When a few gaskets come in that I ordered I will begin putting the K341 back together. First the carb will get a cleaning. Don let me drive his 1980 Hi-Lux 4x4 Toyota Pick Up to Bojangles for some grub and it was a real treat as I had not driven a stick in a long time. It took me back to when I was driving my 1981 Hi-Lux 4x4. Thanks a lot Kevin and Don ! 4 3 Share this post Link to post Share on other sites
