Assuming there are any of you out there, how did you get your intake closing shims off? Ducati sells a special tool for over $500 to get them off, unless you take the heads off. I don't really want to split the bike in half to take the heads off, and I also don't want to spend $500 on a tool that I will use once..

I've searched online everywhere, and the tool is basically non-existent for renting/purchasing outside of ordering directly from dealership. The part # is 887133924

Any experience and/or advice is appreciated!

You can buy it, then sell it after you use it.

That may be the only option. Was hoping someone would have some first hand experience. Also not looking like there's a big market for it when I try to sell.
 
You’ve got a high end bike that will need its valves looked at more than once - the $500 you spend for the tool will pay for itself easily (assuming you are even able to buy it) or....make a friend at your dealership and borrow it

Tried that at a couple dealers. Didn't work lol.

Do you have a selection of shims as well?

Yep, just a phone call or online order away.
 
Last year I performed a clearance check and all the valves were within tolerance. The values that I recorded suggested that some adjustments would likely be in order the next time around (mid 2019). I flipped through the shop manual at the time to get an idea of what special tools would be required. I came up with 887133468 (tool to remove half-cones/split rings… $113.00) and 887133467 (tool to fit valve collets… $200.00). When I saw your post today I took a second look at the shop manual because I couldn’t remember a $500.00 dollar tool being required to perform the job. I still can’t find tool 887133924 shown in the shop manual procedure. Did I miss it? You’re correct, the tool does exist and it’s listed in the parts catalogue as a tool to remove the half-cones, and it does sell for well over $500.00, but do you recall where in the manual the tool is shown to be an item required to perform the service? Do we have to spend $300.00+ or $800.00 for tools required to perform this service.

It is on page 150 of my pdf format service manual. Ill try to take a screenshot. Not sure if the 1199 service manual is any different either. The tools you are talking about I believe are used if you take the heads off the bike. I've noticed the service manual for these bikes is very vague, and also a lot of errors. Can make it difficult to follow.

Thanks. I don’t recall seeing a shot like that in the 1199 manual, but the tool is listed in the 1199 parts catalogue. That's what prompted the question. I’ll have to do some more research before handing over the bucks to Ducati.
 
did you end up having to purchase the tool? coming up on my desmo, trying to learn and figure out as much as i can.
 
Yes I ended up buying the tool and still have it. If anyone's interested, I would rent it out to them for $50 plus shipping. (Would need deposit of full tool price, then refund -$50 when I receive it)

A quick look at the hdesa site shows they do not make this particular tool.
 
I could have sworn there was a website which rented those types of high dollar limited use Ducati tools.
 
There's a number of us that have them depending on where folks are located and agreed hopefully some service centers would help out. Quick not on the tools above but there are two versions of the same tools both for tightening the valve collet to spec ( should say this in the manuals)
 
Fantastic site with lots of good information but it looks like it only covers the olders models correct?

Seems like this would also be a great opportunity for Ducati service locations to support local enthusiasts?
 
I wouldn't be surprised if the basic principle is the same, immaterial of older or newer models. It's a great site to familiarize oneself with the principle behind desmodromic valves, which aren't really complicated.

100 agree its a great resource. They did change how the shims are attached on the intake side as they switched from the "split rings" to "valve collets". These require special tools to be torqued properly before you can recheck the valve closing clearance.

The general idea of the 4V process otherwise is similar. Thank you for sharing!
 
You don't need the tool. Make sure the piston is at TDC for the head your working on, then push the shim down. The valve will move, but it'll stop at the piston. You're not raming it so you won't do damage. Then remove the split ring and slide the shim off. I did this 2 years ago and no issues.
