Big Block Carc Timing Chain

[LittlewGhost]

A few weeks ago, as my bike is looming on 200,000km. The bike being a 2006 Griso V1100. 
Ive owned it from new. 
The mighty Beast has done mostly longer trips. Has been treated well and a little abused from time to time.  With great love of course 
I'm a novice mechanic, if I could even be classed as that.  Maybe really just a bloke who likes tools, and swinging them around to look like I know what I am doing.
Feeling pretty good about it when things go right, and wanting to throw all the toys from the cot when the things go wrong.

I've documented this task on my youtube page with a little film of the task.  Feel free to have a look should you desire.  I'll post a link below to the video.

The griso has really done me well. It remains a fun as hell bike out on the open road. And a naughty child when in the city, (one place I prefer to avoid)

I do quite enjoy filming the journeys and stuff on the Griso, as well as some of the maintenance stuff.  If that interest's then look a bit deeper.  Or Not 

Love to hear about others Griso's experiences and quirks encountered.

Well that was pretty good.
I’ve had mine apart 3 or 4 times while trying a set of gears, which I ultimately decided against.
A couple of things really help to expedite the job and they are a rattle gun and scissor lift.


The driving key in the oil pump sprocket can be fitted after the sprockets are on the shafts, a screwdriver can be used to rotate the pump shaft.
It would have been highly prudent to plug the drain holes in the timing case wall while working there. A dropped bolt or key into the engine is not a nice thought.
You did well getting the crankshaft sprocket on over the Woodruff key, without dislodging it.
How did you lock the transmission while you undid and re fitted the cam/crank and oil pump nuts ?

My bike is a 220,000 km ‘07 Norge, but is very similar inside to you Griso.

Just a thing with the tensioning spring on the new blade…
Did you notice the slight bending where it contacts the cases ? I relieved that when I refitted my chain.


Also.
I was not happy with what I rate as extreme force on the new tensioner blade, so I had a new spring made that is 15 mm longer.


This in my opinion, reduces the load on the spring and the excessive force on the chain.
But no mistake…
You did well…

To lock the drive, I put in gear, applied some preassure to the rear brake, and also put a screw driver through the hole in the disc, snug up against the caliper.  Prob not the most ideal method but it worked.
I sure noticed the tensioner was more firm and very snug in position. I have not done anything with the spring.
Yes those keys were a pain, mostly the oil pump one.  Never gave a thought about sealing those holes. but sure would be a good thing to do with the chance of dropping something down there.  whew, thankfully I did not.

Absolutely on the hole plugging thing, but it all went ok.
Yes, the sprockets can be fitted without the oil pump key in place. As mentioned, you can bring the pump shaft key way into alignment, post fitting.
Your video showed you having little trouble sliding the sprockets on….

Yes I did have some trouble getting things lined up, in ways more second guessing that all was ok before putting all the nuts into place, incase something was not right.
My fear was hitting the start button and all exploding into carnage.

No…
I said you were having little trouble, not a little trouble.
You did a good job, it’s the moment of truth when you hit the starter.

Oh yes  haha.... it was no where near as bad as I imagined.

The new chain tensioner rests on the side of the timing chest and transmits more "chain sound" to the outside world. But it is a smooth and satisfying voice of a happy system.

The vintage BMW guys usually replace the crank timing cog when replacing the chain. I did the same on my T3 (out of past BMW experience and guilt).
