I recently acquired this free Powermate generator with a blown Briggs and Stratton Engine. This is one of the rare ones that has an oil sensor. With any luck it did not run out of oil and maybe the engine can be rebuilt.

Love the string wrapped around the emery paper in the crank journal technique.

@jinbeiktr208 Год назад

I bought it 7 months ago on sale. I waited until I used this ru-vid.comUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y before reviewing. Bought for my travel trailer and runs everything with ease. My neighbor was so impressed with how quiet it was while doing my brake in he just bought one.Pros:Quite Plenty of power Handles and wheels help move Dual fuel Ez start every time so far Cons:Heavy

@schrodingerscat8621 Год назад

I’d like to share a little trick that my machinist showed me. When removing alignment dowels, find a small 1/4 socket that fits on the inside diameter of the dowel. That way when you grab it with the vice grips, you don’t deform it on removal. A drill bit of the appropriate size would probably also work.

@mauricekeithjohnson2598 3 года назад

New to this site and like what I see. Smiled at the hand lapping procedure. Exact same as I was taught 65 years ago.

Excellent! As always! I liked the dual use puller (two holes opposite/three holes equally spaced).

I have this exact engine manufactured 11/22/1999. We've been without power for over 2 days because of hurricane Helene. My father gave me this generator a couple years ago and the last time it was used could very well have been 1999! I cleaned up the carburetor and got it running and all was great for 2 days. I then noticed it sounded strange then all of a sudden it started making a horrible noise and I powered it off. I tore it down this evening expecting it to be bad but I was surprised to find that the 2 small bolts for the connecting for cap had worked their way out some. The one with the dipper had backed out about 1/4" and the other 1/8". Hopefully all that's needed is a new connecting rod.

Thank you for these videos. Things that I appreciate about your videos: 1. The information that you are magnanimously sharing with us nonprofessionals. 2. Your modest learned teacher attitude. 3. Your videos have no music. 4. No theatricals, superfluous talk, or takes of unnecessary objects in your surroundings. 5. Your comments matches what you are doing. So I know what you are doing when you are doing it. 6. You do not keep asking people to like your videos or subscribe to your channel. I have a made-in-Turkey generator (with a Briggs and Stratton engine, Italian coil, and a Japanese carburetor) which was imported by the Saddam government (and sold in Iraq), I know now what to look for in case it breaks. Thank you again! Greetings from Iraq🌹

@billhauck7872 3 года назад

Recently purchased a Briggs that was on a logsplitter but was run new with putting any oil into the engine. It had has a bad knock so I am sure the rod is bad. It has electric start and I only payed $40 for the engine. I was waiting to see how to replace the rod and you did a great job. Thanks a lot for you video. The use of acid on the crank should be the best tip I have heard for removing rod deposit on the crank. Mega thanks, Bill

Hey James! I just want you to know that I consider you the best generator man on RU-vid. I started repairing them a couple hurricanes back (I live in Houston) for the people in my subdivision. I have probably repaired around 60 so far. I very seldom change people for a carb cleaning. I am retired so what to heck right? Gives me something to do. I want to thank you for taking the time to share your knowledge with people like me. I have been cleaning carbs since I was 14 so that part was easy for me. I have learned a lot from you my friend. Keep up the awesome videos. If I ever run into a generator that stumps me I will contact you.

@shawnmrfixitlee6478 3 года назад

great job James ! I find that when the head gasket starts to leak and cause lower compression, the engine RPM's increase when the load drops off the generator. This causes the rod to have extra stress . also causes a lack of oil that can stay in the rod bearing . Sure ENJOYED ! Thanks..

Dang cliffhanger! 😉. Superb as usual. Need to get a set of impact sockets. I keep waiting for one to break or the inside to strip out on ya.

We'll be waiting for part Deux on this one!

@scottdenhamrealestate7716 3 года назад

You have said that most of the Briggs engines are oil starvation issues. This looks like a classic case with the owner adding fresh oil to see if it will work. Unfortunately for them it was to late. Looking forward to seeing part 2. Great work.

@jcondon1 3 года назад

Usually when they run out of oil it is a slow process over hours and everything is coated in burnt oil. Not this one. Think someone ran it on a hill and killed it quickly.

@RGD-Audio-Repairs 3 года назад

The crankshaft is perfectly fine to be re-used :) If the lower measurement on the micrometer, is based from within the middle of the crank journal... Thats perfectly fine.. The issue is, if its the outer measurements, consistently, around the full diameter of it.. Thats when it will cause issues or excessive wear on new crank end bearings... As yours stands.. Perfectly acceptable measurements from a use part, and perfectly fine to re-use.. (i have rebuilt many car engines... And fully forge built mine)

@MollydogRadar 3 года назад

The lubricant you put on the valve stems looks like the STP oil treatment I used on crank shafts when I rebuilt car engines. Never spun a bearing using STP.

@h7qvi 3 года назад

Oil sensor was reading 300k to 2Mohm. Useless as a cutoff. It needs a vigorous rattle and shake to clean the contacts. Should read as 1ohm or less. Another fix is to feed current through it using a 10W bulb in series with 12V.

@FarmCraft101 Год назад

For what it's worth, I think the service manual is wrong on that crankshaft spec. I noticed that is said 1.2475" (31.68mm). If you check, 31.68mm is actually 1.2472". So the fact that the inch/metric measurement they give in the same place don't even agree really says something. And obviously if 31.68mm is in spec, then so is 1.2472, so you were within spec on all measurements.

@jcondon1 Год назад

Another thing I did not consider at the time was the combined wear allowed for the crankshaft journal and connecting rod crank pin bearing. Combined allowed is 0.003". The new connecting rod had no wear, so 1.2465 on the crank still would have been 0.001" above the combined reject size using the service manual numbers. Seams better to measure the gap between the parts then base reject sizes on only one part in the system.

Looks like one I found the other day but the Briggs was red. When I got the head off there was over a 1/2 inch of rust and debris sitting on the piston stopping it from turning over. When I got it out the cylinder had the worse scraps I’ve seen. Both valves were bent.

For removing aluminium deposits from crankshafts (or other steel parts) try using caustic soda (sodium hydroxide) instead of acid. Aluminium dissolves in caustic soda solution but steel is not affected.

@28YorkshireRose12 3 года назад

That engine has definitely been running hot! - From past experience, I'd be a little bit suspicious that the head might be distorted, hence the exhaust blow at the gasket. That said though, if that oil sensor was loose, it's also possible that the head was incorrectly torqued. Other than that, it all cleaned up very well - It's a survivor! It will be interesting to see how it runs, and to see how lean the fuel mixture is. I think a bit rich is definitely better than even a fraction too lean. I was surprised to see those concentric slip rings! I thought they were last used by Noah, on the Ark! - The Lucas ACR series automotive alternators used that approach, but it suffered badly with excessive wear, especially on the outer ring.

@jcondon1 3 года назад

Not to spoil the next video, but the carb was a clone and it ran the engine very lean and poorly. Ended up swapping in an OEM carb. Big difference!. Not the first Briggs clone I have run into on these. The last one was running very rich. I have had bad luck on generators with clone carbs. Only clones that were any good were on Honda clones, Yamaha and GN220.

One thing you can do when removing the dowels on the block is to find a drill bit or something the same diameter as the inside of the dowel and slide it in before grabbing it with the pliers, reduces the chance of crushing the dowel.

@jcondon1 3 года назад

Good idea. The dowels on the pre 2005 Briggs OHV engines are a pain to get out. Did not show it, but it took a bit a work before going to the vice grips.
