Default gear mesh

What do you all use to set the spur gear mesh? One guy at the LHS told me to use a peice of copy paper, then another guy told me to use a peice of magazine paper. What is the best to use? I know that copy paper is thicker then magazine paper.

Just regular paper will do fine. The thin magazine paper is too thin and your gear mesh will be too tight. You don't have to take my word for it, just try it yourself. Use the thin magazine paper and you will find the gear mesh will be too tight. You can verify that when you spin your wheels just with your hands, it will have a high whinding noise. Then try with the regular writing/copy paper and you will find that aweful noise is gone and you will have the proper amount of tick between the clutch bell and spur gear.

i don't think it matters, i use the paper (what ever it is) not by the thickness of it but by the pattern that it makes as it goes through the gap between the pinion and spur

look up squirrelod on youtube and look for his gear mesh video. he goes through the 'paper' method and shows you what to look for.

hope this helps

I always eye my gear mesh. I will get very close and mack sure I have very little gear mesh. I then rotate the gears a quarter turn check it, rotate it again, check it, and tighten it.

Mark 1 Eyeball.

Then I push the car across the track, If the gears are making more noise than me and my mechanic mouthing Vroom-Vroooom noises, then its too tight.

I cut a piece of a plastic baggie or ziplock and set the mesh tight with the baggie there and it is perfect.

The trick is to have your mount just barely tight so you have to tap the edge of the motor mount over against the spur gear, then very gently tap from the other side to move the engine away from the spur gear , you will develop a feel for meshing, you want the smallest amount of play that you can get with out it having no play.

Oh yeah do not forget to tighten it once it is right. You want the mount to be tight enough to hold the mesh in place once you find the sweet spot so that when you turn the car around to tighten the mount screws the thing does'nt accidentally move and change the mesh.

Too tight and you'll wear out your clutch bearings. Too loose and you'll just prematurely wear your gear faces out ...clutch first.Look at the mesh very closely and you can see the play between the mesh ,push it all the way up tight and then start coming away from it and look for the first sign of play. You will get so good at this it will be ridiculous just do it over and over a few times before you snug it down tight and you will develop a technique for doing this without paper.You know hold the spur w/ 1 hand and wiggle the clutch gear back and forth while eyeballing it.Having the engine mount just barely tight enough that you have to intentionally move it,this will make it a precision like adjustment.
