    Keep in mind, I missed this during rebuild of a 1980 3.5hp Briggs vertical shaft, the crankcase gasket, there are two for this engine, this one needed the .015. I could barely pull the engine through, broke in all back down miked everything put it back together and still was so stiff, I did get it to start. but pulling it through was just too hard to do and I knew there was something else that needed my attention. The dealer had sold me a .005. I didn't give it a second thought, until I remembered reading about the two different thicknesses. What a difference a few thousands of an inch make. Great channel.

    Well done and even though there is no crankshaft swap in my future, I watched the video anyway just because I like the way you do them.

    Using the air tool to loosen the flywheel was a valuable tip. I always learn something from these videos. Thanks for posting them.

    Awesome video i had a 1965 briggs with a plane crank shaft the was damaged like someone tryed to grind it an make it a 5/8ths shaft an hammered on a 5/8ths shaft an bent the crank i had already threw the block in the recycle bin when i found this video the cylinder walls looked new an the valves looked like they had never been ran more then a hour so i got some other engine with the intake ceased an took out a double sided bearing pto side crank that was on a newer engine style an put it on the old 1965 block i used the newer style head an all the hardwear because the old bolts where flatheads bolts an they never tighten good the rip cord side was a short shaft so i used a new cup an new started the engine loooks cool an i saved the original engine to my classic minibike👍 🎉

    Wow, excellent job my friend!! One of the most informative, concise videos I have ever seen. I wish you could help me with 1 year old Briggs and Stratton with a bent (I think) Crankshaft. I found out you can not cut a 3/4" reinforcing rod with a Lawnmower. LOL!! It was hidden below some weeds I was trimming. Should have used the weed wacker, now I know that. I did replace the Flywheel keyway and the Blade, now it starts. It runs fairly well at full speed but at idle it vibrates like crazy. Oh well, you live and learn.

    I enjoyed watching you change out the crankshafts on the two engines and believe that I could do that. I need to figure out how to get my power generator going which have not been started in many years. It never was used since I had problems with it since buying it, and installing the oil in it. The newest one worked fine, but I never used it since our power never stayed off long, when we lost electricity.

    Was in a hurry one day putting new rings in a Briggs and didn't emery the crankshaft before reinstalling the sump! I thought how bad can it leak? It didn't leak much, just enough to run down on the drive plate on a Snapper rider! Had to stop cutting and clean the plate every 20 min from then on! Live and learn!!

  • @chasbass5321
    @chasbass5321 8 лет назад

    Hi Donyboy, Always enjoy your superb videos. Just an FYI, I took a keyed crankshaft from an 8hp Tecumseh snowblower (that had a broken rod and cracks in the block) and put it into a 10hp Tecumseh wood chipper engine that had a tapered crankshaft. I checked all the specs with my micrometer and everything was exactly the same. The only difference, other than the crankshaft end, between the two engines was the piston bore. I used my "new" snowblower with it's 10hp engine for 3 hours after a big snowstorm and it worked just fine.

    @davidclink2032 5 лет назад

    Best video of small engines to date. I have a 5hp B&S horizontal engine on a go cart. I replaced the carb. It's back together but I can't get the throttle right. I can't find a schematic of this type. No manual throttle capability only the choke. I need a choke rod so could use some advice how toi find one vs making one. The governor is functioning. This go cart engine didn't have the race track in the linkage which interacts with the manual throttle control. I know linkages vary and the model # for this one is no where to be found. I just need an image or schematic reference of how this should connect. The new carb came with the throttle on the carb hooked up. Also, the needle valve for mixture control did not have a spring on it so I'm guessing I use the old one even though the new needle valve looks different than the old one and the ones in the kit. Hope you can help advise about a schematic or and image or two of how this throttle linkage should hook up.

  • @tonym6920
    @tonym6920 8 лет назад +2

    What size impact driver do you recommend for small engine work. There are so many of them out there it's really confusing. I know you require special sockets with an impact wrench. I would prefer something battery driven or electric rather than an air tool. My use is for my own equipment, no commercial work. So basically it would be used on lawnmowers, my riding mower and generator. Thanks Dony, appreciate your help!

    Hey Don, Great video. Exceptional step by step instruction and great camera work. Just wondering why since I don't see a single video on YT on reworking a head on a riding mower with briggs engine. I see them on the small engines where the valves are lapped but nothing on the riding mowers with the overhead valves. Just wondering if new springs, guides and valves and guides can be put in or would it require machinist work and make it more cost effective to order a new head. I'm sure that would be a huge cost though. Anyways would appreciate if you would comment or make a video on that. Thanks for your great channel !
