UCE Chain Adjustment
« on: August 10, 2009, 06:26:28 PM »
Having just now completed a little over 800 mile's on my G5 I thought I would apply a little lub. to the chain,
On checking the adjuster cams I noticed that each cam is set differently to each other, by what seems quite a large amount (in terms of counting the No. of notches  set against the pin.
I've always assumed that both cams on each side of the wheel should be equal, e.g. the pin in the 6th. notch, on each side of the wheel.  This unequal situation must have arisen in the factory.
 Anybody else found this. (my wheels look aligned but not very easy to tell).
 Am I now to set both these came to equal on both sides of the wheel??

What is straight line stability like? If it looks aligned and handles OK then I would adjust by exactly the same amount on each side for now, thus leaving the difference as is. I'd then try to double check alignment - not something I ever found easy using a bit of string and all that stuff you read. Certainly if it's way out it's easy enough to see anyway.

Mine were miles out compared to each other. Only had reason to check when I took my hands off the bars at about 40mph and the bike veered to the right.

I equalled them and it did improve things but it's still not right so I need to do it properly with a straight edge. Snail cams are never really accurate so don't be surprised if you have different settings on each side but it shouldn't be too far out (all of the new bikes at the open day were set equally).

While you're at it have some fun and watch the swing arm move about when you apply the rear brake ;D

The cams on my 99 are 4 notches off when the wheel is properly aligned.
I'd never count on those things to give you an accurate idea of where your wheel is supposed to be.

I use either a 6 foot piece of rigid conduit or a laser level depending on which one I find first and have my kid hold the bike up because you can't do it with the centerstand down. Once you get it put a dot on the cam with a centerpunch and that will keep you in the ballpark next time.

Down at the Rally at the River a few years back I was riding behind a guy and when I was straight back from him I could see half the front tire sticking out the left side of the rear tire (dog tracking).
As he was riding his back was tilted to the right to compensate for the lean or the bike.
When we got back I told him about it and we adjusted it and had to go 5 more notches on right side to make the rear wheel straight.
He had put over 50K on that Bullet like that and never realized how out of whack it was and how comfortable it could be if his back wasn't making a right turn right off the seat.

CJ is absolutly right you have to align the wheels with a straight edge or laser.The cams can be any amount off when it's aligned properly.  ERC

Thanks for all the info/advice guys.
The bike feels as though it is handling OK, but it
looks as though I will have to go looking for a nice straight edge now.(to be sure)
I suppose it makes you wonder then, why they bother to put the snail cams on then!!

I'm an Enfield rookie, my last bike was shaft driven, and the last bike I had that needed chain adjustment was done by pulling back the wheel (no cams, eyeballing alignment). So I haven't yet done a chain adjustment for my G5 yet. Here's my rookie question - when the manual says remove "brake rod nut," does that mean the nut on the end of the brake rod? Why must I remove it?
Thanks for the help.

Yes it does and you don't really have to remove it, just slacken it off a fair bit. If you don't and you're pulling the wheel backwards it'll have the effect of applying the rear brake which at best will make it difficult to move the wheel or at worst will leave you with a rubbing brake once you've finished the chain adjustment.

Yes ---also the h/book also says 25/30 mm of slackness on the top run. Should this read bottom run??

Before I tightened the chain, the cam on the chain side was at the 7th notch and the one on the left was on the 10th notch. I tighten the chain moving the right cam to the 9th notch. I then used a straight edge (8' steel pipe)) to align the front and rear wheels which required moving the left cam back a spot to the 9th notch. So both cams are set equally and the wheels are aligned perfectly.

That sounds good to me Chris, Just as I thought it should be.
I always think that the design of something should work as intended.
I'm off now to find a straight edge;
---but is the slackness on the top run, as per the book, or the bottom run??

The snail cams on my C5 adjust equally, I got lucky I guess.
On the eighth day God created the C5, and it was better looking than anything on the planet.

Not sure about that. I really didn't measure. I tried the 10th notch and it was to tight with minimal slack. So I moved it to the 9th notch and that seemed good.

Don't forget to check it while your sitting on the bike.
They do tighten up with a load on em.

Just got down to this chain adjustment business, after now completing 1158 miles.
I found as reported before the RH cam set at 8 notches and the LH cam at 12 notches.

Have adjusted now so both cams are on the 10th notch, with what appears the right ammount of slack (dam-did'nt check with me on the seat -have to check again).
Found it difficult to check for "dead-on wheel alighnment", but it looks OK from where I'm standing.
As I see it without some methode of ensuring that the front wheel is in the dead ahead position, then its harder still to alighn with the back wheel, even with a straight edge, - perhaps some sort of clamping arrangement onto the front wheel,-- oh, I dont know --it looks OK to me!!!  It's not precision engineering is it?

Regarding the running, after the recall, all is well in the land of Enfield.
Still running in but increasing speeds to arround 60 + now for short bursts. The sounds from the exhaust --great, and pulls very well. Love to drop a notch , and gun past a slower moving vehicle, even my daughter (36) loves the sound of the engine.
