Shaft oil change

I would be interested to know if anyone has modified the plastic trim ring in order to gain access to the rear drive fill point. (If indeed it's possible). I would prefer the option to change the oil as and when as opposed to doing it only when the rear wheel is removed.
 
I have not, but on several I’ve done, I’ve just left the ring off. For those concerned with functionality over vanity, it’s an easy choice. I can’t believe the silly design.
 
Thanks Todd, the bike is soon to go in for its 10000km service and replacement of the fork legs and speedo (warranty). I will be changing the engine and transmission oil myself prior to this but will ask the dealer to leave the ring off when they do the shaft oil.

Hi Robert

I'm not sure that they replace the final drive oil at 10,000km. The service book only states that it is due for replacement @ 50k, not even intermediate inspections are highlighted. It's unlikely then that the dealer will remove the rear wheel to get at the plastic ring (unless you pay them extra).

I intend to replace mine with every new rear tyre. I had thought about access to the "top up" bolt which lies at the 12 o'clock position under the plastic run. There is a rectangular protrusion there directly above the bolt. If you made a small incision to one side of it, you might be able to lever up the protrusion from the other end to gain access (or remove the protrusion altogether which would leave a small hole above) and then tape it down.

I haven't done it myself, but the drain plug is accessible without removing the ring. The difficulty is getting the correct amount of oil back in without access to the "level" plug (again hidden). However if you bought a small syringe you could drain the oil then apply a measured amount through the "top-up" bolt. Just a suggestion, or you could do what Todd suggests and remove the whole thing.
 
Thanks for that, think I'll just remove it myself as my intention is to change all the oils at the same intervals. For the sake of the small quantity of oil that the shaft takes its not going to break the bank.
 
When i removed my back wheel I changed the oil ,
the Eldo had about 1500 miles on it and the oil was silver,
fresh oil went in IIRC 180ML.
While the wheel was off I marked a area that could be cut out of the trim ring to give access to the fill plug.
I have not cut the ring yet and I know that some sort of sticky stuff will need to be used on the allen tool so the plug wont fall into the opening

For what it's worth,

Before purchasing a 2014 California Custom I fell squarely into function over form. Hence my recent request to have Todd fabricate new brackets for the Shorty Zard mufflers. To move them forward enough to remove the rear wheel without removing the mufflers. IMO having to remove mufflers to pull a rear wheel is a really silly design choice.

On the first rear tire change (3,746 miles) I had the rear drive oil changed, and asked the mechanic to leave the really silly ring off. Didn't like the way it looked but decided to wait and see if I could learn to live with it. Managed pretty well too, until the 2nd tire change, due to a puncture at 7,750 miles. Which coincidentally occurred one week later than the 7,500 mile oil change. I figure if I'm ripping through tires every 3,500 miles oil changes at 2,500 mile intervals, with recommended services at 5K (instead of the recommended 6K).
My son had no trouble removing or replacing the fill plug,

Leaving the ring off is definitely a functional improvement. Unfortunately that gap is just such a glaring omission that I couldnt bring myself to leave it in the OEM Cali parts box.
 
I think with some careful trimming the cover can be opened up and otherwise left in place,

for removing the rear wheel,
I removed the rear fender this was not too difficult.
I did remove the center heat shields so the jack stands would not hit them .
I used the rear foot peg mounts to hold the bike off the rear wheel.

Robert,

I removed it and left it off during the last rear tire change. You really have to look to notice that it is not there when you have the MG hard bags.
