I noticed today the steel pinion and spur look like they should be meshed a bit tighter than this:w00t:They are a fixed dimention and you can't adjust these so what do you do?:o

yeah it does look a little on the light side.

this wont change anything but ive never seen the pinion and spur gear installed this way around, i think the pinion and spur needs to be turned 180 degrees and then put back on, this wont help the mesh though.

i run the stock steel spur and upgraded to alloy carrier and steel ring gear that acts as a spur and its absolutley bulletproof.
 
yep wrong way round...and i bet the pinion is rubbing on the outer

face of the bearing:w00t:....needs turning round and shimming with washers

as for the mesh you should just be able to run a piece of paper between

the gears

After you turn them around, if there's still a lot of 'slop', then you may consider increasing a tooth.
Al.

But don't ya have to change the spur/pinion as a pair to get them to match up?I know on the baja 5b they make different pinions to fit one size spur by changing the profile of the teeth on the pinion,do they do this for the FG's?:)
 
what gears are you running :w00t:.......should add up to 64 teeth

you can get diff sizes of pinion with the non standard profile

but not original FG ones
 
what it looks like you have there is a standard diff gear mounted on an

an alloy adaptor ...if so then i think it is unsuitable as i seem to remember

i had the same problem :lol: i got a set of steel gears and all was fine

I'll get some pics up as soon as I start tearing it down for the alloy mounts,which are on their way here:D
 
Ok is this a standard diff gear mounted on an

an alloy adaptor...Or????:o

I'm not familiar with the FG steel gears yet:o

I am betting that one of the gears isn't an fg, maybe a duratrax/carson/smartech.. they are a bit different size. why the fhmt uses 19/48 and the fgmt uses 16/48. the fh motor side plate is a bit different too

it does look like a standard 48t FG diff gear ....quick check is to take the diff out and see the gear that is on that........

Without taking out the diff the gear that's in there now the teeth are almost 7/16'' wide and the so called spur I have they are a little over a 1/4''So it can't be a diff gear??How wide is a stock FG plastic spur gear teeth?This is confusing as hell:(

the ones off the FG Marder are narrow so im thinking its one of those you have

Bingo Treb,That looks excactly like mine in thickness,I'll either have to get an FG one or go to a plastic spur set up,but with this pipe and the torque I don't think plastic is going to last long..opinions???:D
 
You can use and I do run standard diff gears for spur gears. I use DTX gears because they are cheaper. Thinner yes, perform the same yes.
I think what is happening is the spur carrier came with a raised ledge on the back side of the carrier - The area that you have faced out. It looks like someone ground it off flat. That are ran against the gear plate bearing keeping it from hitting or rubbing on the gear plate. You will need to use one FG shim washer to keep it off the gear plate if its rubbing. The gears sometimes will start out tight but after use will loosen.
