Rear Isolastis

Hi

I have read that the rear isos can be changed by a method of lowering the engine and gearbox ,without taking primary covers off. the article describes the commando with a center stand connected to the cradle, as I have an early commando and the center stand is bolted to the frame so it looks like it cannot be lowered,

Is it possible to replace the isos on this early commando without taking the primary covers off by the above method, and has anybody done it.

Any info would be really helpful.

Thanks

Hi there John

There is an 'alternate method' listed here which does not use the centre stand.

Worth a look.

I only have experience with the centre stand method.

Take a look at the video clip by all means but, the primary drive has been removed, the bike shown is a model with the stand mounted on the engine plates and a ton of parts have been removed. Your question refers specifically to the early frame and as the engine plates are already almost touching the cross member on these early models it will be impossible to lower the engine plates enough to access the end of the rear iso tube. Unfortunately you might as well remove the exhaust, primary drive cover, primary drive, the rear wheel, detach the lower end of the rear suspension, you can remove the three bolts from the back of the engine to the cradle, swivel the cradle exposing the cutout allowing the gearbox to be removed, then remove the cradle and swinging arm together. Replace the iso rubbers and service the swinging arm at the same time. About two days work if you have the correct tools and replacement parts. You might have to remove the rear mudguard and battery tray.
