Valve Inspection / Adjustment Tools?
« on: February 25, 2020, 03:51:51 AM »
What's up everyone!  So, I'm barreling towards my 18,000 mile service which I will do myself - and obviously, it includes a valve check.   I've seen with S1000RR motors there are specific tools to index the camshafts back in place to make sure they're timed properly, as well as lock the crank in place, etc, etc.  My past experience with valve adjustments on DOHC motors is that none of that is "really necessary" as you can properly mark / take photos of the arrangement prior to removal and simply replace it exactly.

Butttttttt, I figured I'd reach out to all ya'll who may have done it on this particular motor before I shell out $250 for some one-time-use tools.

So, do I need any special tools - assuming I actually need to adjust the valves - I realize I won't need anything to simply check them.  But yeah, do I need the crank locking tool?  The camshaft index checking jig?  The fixed tensioner?   Yes? No? Anything else?

Thanks!

mine is on 42,000 miles and has had 2 valve checks and is still in spec, I would be very surprised if anything need adjusting based on mine, did say at the next big one a couple of the exhaust valves may need doing, told they get a harder time,

You need a crank locking pin, which isn't anything special at all. A 5mm (iirc) drill bit works perfectly well. Apart from that its a very straightforward engine to work on.

The whole service including adjusting the valve clearances is covered in my book available here:

Hope that helps, Cheers, Mark

What Mark said...the valve clearance inspection isn't really difficult, just a bit time consuming....the need to remove & replace most of the tupperware etc takes up most of the time. Actually checking the clearance itself is a doddle....these days it's quite rare for them to be out of spec....but if it turns out you do have any which need attention, you can buy shims and indeed kits to suit these engines, if you plan to keep your bike for a long time and do your own servicing, it's a good option, I help out a few mates with R's and RR's which makes the requirement for the shim kit worth the effort.

Another thing some don't know is the fact that the cams and cam chain on these Gen-1 S1000 engines actually spin backwards in relation to the crankshaft, I believe the new gen-2 2019 RR and 2020 XR engine is conventional with crank and cams all spinning the same direction.

Interesting that the cams rotate "backwards."   That's cool!

Anyhow, I'm pretty comfortable digging around inside engines so if ya'll are saying (and Marks' book that I can read!) says it's your typical DOHC shim/bucket design, all will be well.  I was more or less reaching out to make sure it didn't have some funky procedure like my V4 Aprilia did, or when I split my GS in half to fix the counter-shaft balance seal.  Haha.

So, less than 5k miles from now I'll dig into her and see whats up!!

As far as shim KITS are concerned, I did some Googling and apparently people are using a  Wiseco VSK4 Premium 8.90mm shim kit that has the same diameter shim we need and seems to work fine?  That sound about right?  I'm not interested in buying single shims from the dealer.

They're not bucket & shim type, they have small "underslung" rocker arms with the shims on the end of those.

Yeah I saw that, shim sits on top and there's little finger/follower things. that push on them.  Bottom line is camshafts come out to re-shim if needed, similar to shim under bucket - without the bucket removal.  LOL

You are also meant to use the BMW tool to check cam timing to make sure the chain has not stretched aren't you?

The tool that fits into the semi circle cut outs in the head casting.
