Drive Chains.

Can any one answer this?

After adjusting my drive chine the other day I found I had a tight spot. So why do we get tight spots?
The chain is new at the same time. The ware is the same over the length. The chain travels over the same sprockets.
So why should you get a tight spot?

Every chain is only as strong as it's weakest link. Add to that corrosion, as well as wear and tear and sudden, uneven power application and chains can soon develop tight and slack spots.
Throw it and the sprockets away and fit new.
 
I have to agree with Grant. If your O ring is tight at one spot then the seal has gone at that point, the only way to be sure is to dismatle the chain which would ruin it anyway. Probably with the seal gone and the bearing dry it has rusted or at worst case gone through the hardening and bent. Change it is ther best thing.

What sort of tight spot do you mean?
A tight link where the chain doesn?t pivot smoothly at that particular pin/s, as Andy has mentioned. This is usually the reason to chuck o-ring chains before they are worn out, they can go dry internally and become unuseable. Not all chains wear evenly over their entire length hence loose spots which we see as tight spots, if you follow.
A reduction in the amount of freeplay when checking the tension with the wheel (sprocket) at the same place each time. This is caused by the sprocket with its centre not in the centre and is usually like that from the time the sprocket is fitted. We won?t mention bent gearbox output shafts.
It sounds like a new chain/sprockets is in your horoscope.
 
I always carry a pair of rubber "mucky gloves" on TOG.If I can be bothered to check and adjust the chain when i am away on a long trip, I don the gloves, get the rear wheel free of the ground and spin the wheel a few times to get a feel for where the tightest spot is, then i adjust the wheel with it at that point.It doesnt actually bother me very much, since I can almost aways detect a tight spot somwhere on the full rotation of the chain.Use your normal citeria for replacement and dont worry too much about it.This will probably work well for "Prenny" since he is a known Kentish tight arse.

when I was working on TH400 autotrans,in situ on the likes of Interceptors,Corvettes, V12 E Types or XJ12 saloons, I was called "Gynacologist fingers" because of my knack of getting into the top of the box with the thing still installed in the car, so be careful out there.
