How do you align a nitro engine properly

[Jason1974]

I have just fitted new engine mounts on my hyper 7 engine and i was wondering what is the correct way to align the clutch bell to the centre diff cog.

[chrisknights]

get a piece of paper and fold it in half and push the clutch bell next to the center diff and nip up screws and pull paper out and push along to feel it feel free

give you a idea

you need to place the engine i place first and just ip up the adjusting screws to hold it in place. then get a sheet of standard a4 paper cut a thin strip off then slacken the screws off place the paper in between the clutch bell teeth annd the spur gear teeth and tighten the screws.then take out the paper and push the buggy forwards and backwards. it should run smoothly if not and the teeth grind slacken it off a touch, if it is set right you should be able to hold both clutch bell and spur gear and there should just be a couple of mm of play

Thanks both Now i got that sorted where does the spur gear teeth need to be on the clutch bell teeth.

You want to get maximum overlap. I know I have had some fun lining up as different clutchbells seem to vary lightly.

If your clutchbell teetch are not fully on the spur you will wear it out quicker...so just make sure you have maximum overlap front/back and that the clutchbell doesn't rub on the spur.

Sort that and mesh as above and you will be running nicely
