about ready to sell FG! very anoyed!!! please help
ok i just got a new JP silenced pipe for i got new alloy engine mounts to solve the engine movement problem (or so i thought) anyway took it for a spin with new pipe was unreal for about 20 mins then DISASTER!!! same old problem cluncking gear nose coming from layshaft and diff gear. I Just can not seem to get the layshaft gear close enough to the diff gear so that they mesh tightly enough. Its almost as if the dif houseing is stopping then engine from moveing any further back as there is clearly space on the chassie for the engine mount screws to go back about another 4mm.
Any ideas im at a total lose end and ready to get shot of the whole thing as i have had this problem from the start :( |
RE: about ready to sell FG! very anoyed!!! please help
hi mate, have you used hi strength threadlock on the mounts and all mounting screws/bolts? also have you superglued the engine-diff brace screws in? if not this could be your problem.you will have to use a blowlamp or gas soldering iron flame to get them off again! but thats reliable largescale methods mate;) where nare you in uk? if you keep having problems bring it down to a local race meeting and we'll sort it out.
|
RE: about ready to sell FG! very anoyed!!! please help
yes i use threadlock on all metal to metal screws but i dont use superglue on engine-dif brace (This i take it is the almost triangle shaped metal plate that sits on the diff housing and engine?)
alos i dont have a local race meeting lol the nearest place i have to me is halifax and live up in the northeast on teesside about 5 hours drive :( sucks i know |
RE: about ready to sell FG! very anoyed!!! please help
we have a very friendly track at wakefield called the nook, thats nearest i think. its the norm for us to travel between an hour to 3 hours to go to a meeting.
well somethings moving and there will be a way of stopping it, i use superglue on all stressed metal to plastic fixings. yes the brace is the triangular part. trouble is 95%of model shops dont know what there talking about with largescale, especially offroad. dont give up! |
RE: about ready to sell FG! very anoyed!!! please help
yes i know what u mean its not a commen thing to have in most model shops. do you have a list of times and dates and conact names so i know hen to come down and who to look for? im going to go home tonight and take off the rear end so only engine is left and build it back up bit by bit see if i can find out what is stoping the engine from not been able to move back far enough to mesh those damn gears.
Buy the way i think i forgot to say its the monster truck i have lol kind of an important part to tell u guys ::p Ooopps!! |
RE: about ready to sell FG! very anoyed!!! please help
I just bought a FG MT a few weeks ago and i've already torn two teeth off the rear diff gear and got that rear clunking noise as well.
I'm waiting on a new diff gear and I bought a steel gear for the smaller one (no idea what it's called?) I hope i don;t have this problem again. So your is from engine movement? |
RE: about ready to sell FG! very anoyed!!! please help
well the diff cannot move so i'd remove the screws one by one then superglue them.then remove the diff brace.
then i'd loosen the 4 engine mounts, mesh it up again on the diff ring gear,threadlock the sucker back in then refit the diff brace using superglue. that shouldnt move then mate. http://www.nookraceway.com/main.asp they got a forum so ask away:D |
RE: about ready to sell FG! very anoyed!!! please help
right o mate will try that but im not convised it will work but i wll try anything now as im all out of ideas. Thanks very much for your help.
If anyone else got any other info or ideas i would luv to hear them to Cheers guys |

ORIGINAL: JUCD VPR I just bought a FG MT a few weeks ago and i've already torn two teeth off the rear diff gear and got that rear clunking noise as well. I'm waiting on a new diff gear and I bought a steel gear for the smaller one (no idea what it's called?) I hope i don;t have this problem again. So your is from engine movement? the spur gear is the large plastic one that is on the side that meshes with the pinion gear(the small one that comes off the engine/cluch) usually if these gears strip its because the rear upper arm flexes and hits the spur gear(the big plastic one) this is most peoples first hopup, replaced with alloy items to stop flexing. the elcon rear upper arms are the strongest. |
RE: about ready to sell FG! very anoyed!!! please help
what size gears are they.the ring gear and the lay shaft gear......wonder if they need to be a matched set like 16/48 or 18/46
maybe just maybe if you got a 16/46 your motor will not go back far enough to mesh............just an idea |
RE: about ready to sell FG! very anoyed!!! please help
yeh maybe your right i never thought of that i will check that 1st so what gears should i have in there? 16/48?
also i just thought i cant superglue anything in i dont have the tools to get them out again lol DOHH!! |
RE: about ready to sell FG! very anoyed!!! please help
NOPE not confusing them, i know what a diff gear is lol. Like i said it tore two teeth off the diff gear, my spur gear is completely fine, then i drove it anyway and it tore up the other little gear that the diff gear meshes to, but i have a steel one to replace it with and a new diff gear coming also.

RE: about ready to sell FG! very anoyed!!! please help
I believe mine was from a rock though because the cylinder is scrathed up pretty bad also.

ahhhhh the plot thickens

RE: about ready to sell FG! very anoyed!!! please help
Since you guys are in the UK (less expensive shipping) you should try to get the Extreme Duty diff and layshaft gears from HobbyThek. I bought them for my Firehammer, got a small alloy engine mount and have not had any problems since. The gears are much tougher than stock FG and Smartech gears. The teeth are "regraded" to allow more slop in the mesh without causing problems. Check them out here (you will need to scroll around on this page):

RE: about ready to sell FG! very anoyed!!! please help
To solve the engine movement problem, save yourself a lot of grief and do what I did. I retapped the the 4mm holes in the alloy motor mounts to 10 mm and used some good allen head screws. Hint: The Dremel tool is your friend. I also believe that that triangle brace that holds the large motor mount to the the diff mounts is also a culprit. But that's probably just my opinion.

RE: about ready to sell FG! very anoyed!!! please help
Well guys guess what.... notmans idea of gears been wrong sizes seems to be the problme im not getting my hopes up yet but i went home and checked and the pinion gear is 14T and the diff gear is 48T hummmm let me think???
I like your idea of drilling bigger holes in the mounts i was also thinking about doing that too but its nice to know its been done and works fine before i did it. I have checked out that website kengentry5000 and im going to leave it for now i think and wait till i got the cash then buy both the diff and pinion gear at the same time. Thanks for all your help guys i think my worries may just have been sorted :D:D:D (fingers crossed) |
