K1 Build Advice

[Tobamory]

Just going through the motions with the K1, not had a belt drive before

Ive just completed fastening the 2 diffs to the chassis and securing the belt etc.
I had a questions

When I spin the belt should it be smooth or clunk a little. when I say clunk I mean like the teeth on the belt noise.

thanks in advance. just don't want it wearing out if it should be smooth as. although I cant see anything wrong, it may be out of align slightly

Difficult to know what you mean exactly by 'clunk', but by hand a belt drive when built probably won't be overly free and smooth to be honest. For example, you may find that with the wheels on, turning one corner will result in the diff working (like there's a motor meshed if you like). As opposed to a shaft drive which would be pretty free from new. The belts will stretch as they wear in, so check your tension after each run initially.

You shouldn't really be able to mis-align the belts. If you were to get the diffs in the wrong way, it would be obvious it was wrong. Worth double checking the fences on the diff gear are the right way round - the chamfered edge should be pointing inwards, towards the teeth.

thanks ive checked and they look the right way, I think its right to be honest but I had to ask.

Thankyou
