I have an oil leak that appears to be coming from behind the final drive sprocket on my G5 Bullet 2009. Has anyone here had to replace this? Does it involve splitting the cases? Are there any special tools required? I am happy to do this, but would like some guidance from people who may have encountered this?

excess chain lube ?

[Moreirdan]

No, I know it is a leak, not chain lube

     Your kick start seal is leaking. It usually occurs because the plate that holds the seal is not machined quite right. This gives the seal a side load on the shaft, leading to failure. You need alternator cover gasket #570416, seal # 570241 and 3-Bond 1194 sealant. Remove the alternator cover. Remove the sprocket to access the seal plate. You'll need a big socket and an air wrench. Remove the plate and grind/file/trim the screw holes so it will center the seal on the shaft when re-installed. Use the 3-bond when re-installing the plate. DO NOT USE ON THE GASKET.

Before you break out the spanners, run the chain through a rag to clean off any excess, and clean up the final drive.

Make sure it isn't too much lube on the chain, as an overlubed chain will drip around the final drive sprocket

+1 Northern Monkey, I had the same issue. The nasty crap on the chain becomes molten after a long ride and is slung everywhere then drips in the exact spot that Moreirdan mentioned. When it cools it turns into an almost imoveable waxy substance.

There have been many posts like this.  So far they've all been chain lube.

I have the same issue, most probably it's the chain lube....

Not an Enfield, but I have had the countershaft seal leak on several bikes. All Japanese. Most can be pried out with a screwdriver, and a new one installed by driving it in with the right size socket or piece of pipe. That seal is currently leaking on my XT225, but it only leaks when the bike is on the sidestand, and the seal is below the oil level. When I put it on the aftermarket centerstand, it doesn't dribble oil on the garage floor, and it does not lose enough oil to be concerned with while riding it.

This 'leak' turned out to be chain lube.

I ordered new seals for my kickstart shaft. They came just as I left town for a month. Now I can't find them. Leaving for a few days. If I find them on my return, I'll post what I find. I can tell you this. Mine is not lube.

Just below the countershaft sprocket there is a round transmission cover. These have been known to leak too. RE is totally aware of this problem. It doesn't use a gasket, just sealant. I have repaired a couple of these already. It is a simple fix but the countershaft sprocket does have to be removed to access the bolts to remove the cover. I posted about this issue on another thread here about a month ago.

A friend told me the leak is on the trannie shaft and it's there because the sprocket grooves are machine too long and cuts the gearbox seal. He said that Enfield has a fix that replaces the seal and has a thin collar that goes over the shaft that keeps the seal out of the grooves. It comes with some sealant that seal between the collar and grooves to keep the oil from running out between the collar and grooves.
He used it on his bike and did have to reapply the sealant because he didn't use enough the first time.
Still, a lot of the "leakage" is chain lube. Mine was.
