Coleman ct100 sidecover

[pearl111]

I removed the governor from my Coleman ct100u mini bike. I look around but can't find the torque specs. for the side cover bolts. Does anyone know the torque specs. Was thinking of going with 17 ft.lbs. like the Pred. 212. motor.

I forget the brand name but the motor is 99cc if this helps any. Thanks for any help.

If no one else knows, you can just put some blue loctite on there and use common sense.
Guesstimating an' eyeballin's only hurt a few people.

A good guideline is tight, and then an eighth of a turn more.

I'd do 17 foot lbs of torque or do the equivalent in inch lbs (204), like the Predator. These clones are basically all the same.

Do not use Loc Tite (or threadlocker) if you don't know. That's not a good idea and that will bugger up your threads thus preventing you from torquing them down to proper spec when you do find out the documented specifications...

I trust this source:

Hellion thanks I will cautiously tighten until I find proper specs. And also keep an eye out for any oil leaks.

You may not find specs for this particular engine. I don't think the Chinese factories really provide that, much less a tech manual (in English) for that engine or the family of engines they manufacture. I'm probably wrong and they're available out there in cyberspace...

Since they're all clones and copies of pre-existing Japanese engines, I'd look up the specs for Honda GX-### and use those.




However, as an example...
Looking at the specs for the L-head Briggs engines, 3HP to 5HP, the torque specs for the cylinder head are all 140 in. lbs.

The connecting rods are all torqued to 100 in. lbs.
The crankcase cover is torqued to 85 in. lbs. for most of them in that range except...
...
The 100200 (4HP) and 130000 (5HP) series have 120 in. lbs. for the crankcase cover.

The specs go up with HP and/or displacement.

Thanks again, advice well taken.
