Radder in Larryville Posted July 10, 2021 Share Posted July 10, 2021 I was looking on the LCEngineering site and saw they sell various weights of flywheels. I am currently rebuilding my 22RE and swapping the automatic for a manual. Does anyone have any experience with the heavier flywheel? My thought is the a heavier flywheel will help the little engine maintain momentum on hills. I am concerned that it would be harmful to the overall performance during a long hill climb though. Can anyone shed some light on the flywheel weight and results on our toyhomes? I am only finding information on the heavier flywheel in the rock crawler community.

extech Posted July 10, 2021 Share Posted July 10, 2021 flywheel weight only affects changes in engine speed. the lighter the flywheel, the faster it can rev up. on a long hill the engine speed isn't changing so the flywheel is not a factor.

Radder in Larryville Posted July 10, 2021 Author Share Posted July 10, 2021 Thank you for the quick reply. So, it sounds like this would only effect acceleration/deceleration, and not overall power. I guess by that logic, it would be best to get the heaviest flywheel possible. Does anyone have any experience with this? Quote Link to comment Share on other sites More sharing options...
fred heath Posted July 10, 2021 Share Posted July 10, 2021 Lighter flywheel will help with rpm on acceleration. Also help with engine braking. Go lighter if anything not heavier. Quote Link to comment Share on other sites More sharing options...
extech Posted July 10, 2021 Share Posted July 10, 2021 i agree with fred. heavy flywheel will help low rpm engines maintain a desired rpm Quote Link to comment Share on other sites More sharing options...
WME Posted July 10, 2021 Share Posted July 10, 2021 Rock crawlers use a heavier flywheel to help when they lug the engine, the added inertia prevents stalling the engine and makes things a bit smoother. Racers use the lightest possible flywheel to REDUCE inertia and let the engine build RPM quicker. On an underpowered, overweight pickup (thats what a Toy House really is) the stock one is OK. Steady state speed the flywheel is a moot point. Quote Link to comment Share on other sites More sharing options...
extech Posted July 10, 2021 Share Posted July 10, 2021 our sprint car had no flywheel. rpms changed in a blink of an eye. 10 second quarter mile ---in a circle Quote Link to comment Share on other sites More sharing options...
Maineah Posted July 11, 2021 Share Posted July 11, 2021 OK, how did you get it started and what was the clutch attached too? Quote Link to comment Share on other sites More sharing options...

What ever you use for a fly wheel will be lighter than the old converter! If you have a choice I would go lighter but it's kind of doubtful you would ever notice a difference one way or another with the MH. Quote Link to comment Share on other sites More sharing options...

extech Posted July 11, 2021 Share Posted July 11, 2021 yes, pushtruck. no clutch. in gear or no. if you stall it , truck pushes you to go again Quote Link to comment Share on other sites More sharing options...

linda s Posted July 11, 2021 Share Posted July 11, 2021 Toyota motorhomes main problem is getting it moving and stopping it. A heavier flywheel will make it worse. Stick with stock Linda S Quote Link to comment Share on other sites More sharing options...
