Hi guys I am in the final stages of rebuilding my panigale 1299 engine after giving it a look over and refresh. I have purchased this tool to fit the piston pin circlips as it makes the process a bit more elegant than trying to fiddle with them and a screwdriver. It also allows to remove the liners without splitting the case halves. However I have found that the pilot shaft is too wide to fit in the gudgeon pin of the 1299 panigale. I have seen this tool used to assemble an 1199 piston before and it appears that the hole that runs through the gudgeon pin is larger On that motor than the 1299. The part number for the tool is that which I found on the parts catalog and the manual and it’s printed on the tool So I can’t understand why the diameter of the pilot shaft is wrong unless there’s an error there. does anyone know if there are separate pilot shafts for sale from Ducati that are specific for the 1299 and this tool?

cheers!

Pitch those heavy ... stock wrist (fergrudgon?) pins and treat ur motor to some nice tool steel pins

Call Sheila at Schnitz Racing. Tell her Tank sent ya she will hook you up : )

*the reason it don’t fit is the stock 22mm pins have 7mm wall!

yeah I am not in the position to replace them at the moment. I was just wanting to reassemble the engine as I have it. Maybe next rebuild I’ll update things. The tool is a official Ducati workshop tool so why wouldn’t it be designed to work with standard pins? It’s the same tool code as used in the 1199 workshop tools section of the parts catalog but on the 1299 catalog it shows the tool in its various parts. All it would require is a different sized pilot shaft and surely they have that as I would imagine Ducati use that tool or a similar one at the factory.
 
I have the complete shop tool set that includes those tools. Unfortunately Ducati does a lousy job with the catalog and descriptions. The engine stand was my first foray into incorrect part numbers. The 1199 engine plates for the stand will not bolt to the 1299 engine case as the 1299 swing arm shaft location is slightly different than the 1199 however the part # for the 1299 and 1199 are the same. Turns out there is no engine stand moving for the 1299. Shops have been making that piece. This is true for other factory tools as well. I have two versions of the pin retainer tool. I’ll look at them tonight. I have had to source 1299 specific tools that are not in the catalog.
 
Ah right I see! If you could give me a part number for the tool that fits the 1299 pin for the retainer clips that would be great!! Is it possible to buy just the pilot bit that goes into the rest of that tool as it would save me buying the whole tool again if it is interchangeable with the main tool body. I measured the parts up and the pilot of the tool is about 10.690mm whereas the ID of the pin is about 10.030mm so just slightly off. I’d like to have the ability to use it for an 1199 as well so I don’t want to take it to a lathe to size it correctly if I can buy a separate pilot shaft for the 1299.
 
The 1199 wrist pin OD is 21.97mm, ID is 10.87. The 1299 wrist pin OD is 22.97mm, ID is 12.43. The 1299 tool has a larger pilot shaft and a larger retaining ring sleeve. You are not going to be able to get those pieces separately. I'm looking for the correct part #. I do not believe it is in the standard parts book but I could be wrong. I'll have to get the one i have and cross reference it. 1299 pin on the left

What version of the 1299 do you have as those seem completely different dimensions of the pin I have. Mines a standard 1299. Pin OD is 21.994mm ID is 10.027mm and the shaft diameter of the tool I have is 10.683mm.

*had : )

You posted at the same time I did Dean. That was for Ed not you. Ditch those heavy ... pins man. I didn’t even put one on a scale just threw them in the trash. Seen diesel motors with less wall in the wrist pin!
 
I got those numbers from measuring the pins in the pics I posted. Don you don't have a true 22mm pin. Its going to be 21.??. The pins I measured are from a 1299 SL and a 1199R. Regardless, as I suspected the part number for the tool in the 2014 1199 and the 2016 1299 manuals are the same. Another Ducati debacle. 1199 tool shaft is 10.68. there is no factory retainer clip tool for the 1299 at least from Ducati. I suspect the one I have was made aftermarket along with a bunch of other odd ball tools. I got all my stuff from a Ducati service rep. The set was used to train the shops. Don, we are all aware of lighter pin alternatives. This board just isn't the place for it.
 
No worries. I’ll look into it next time I go for a rebuild. Just have a time frame to sort this motor out at the moment just generally went for a refresh than a performance build.

Ok thanks that explains the difference in dimensions of our wrist pins. I’ll have a chat to the dealership that sourced my tool and if there is no alternative to this one then I’ll take it a local machine shop to be modified. It only needs around .7mm to be removed to work.

A 116mm piston isn’t 116mm. The bore is but the piston itself is slightly smaller. There’s clearance. Same deal with wrist pins. The wrist pin boss in 1299 piston is 22mm in diameter. Yeah turn that tool down .020” a side and it will work for both

*I’m gonna run spiral locks in mine no clips but apparently I am not supposed to mention that here : )

Yea thanks for chiming in a schooling all of us novices however, I still believe you are inaccurate. I do not believe that your wrist pins pings 22.00 on a slide indicator. Im betting that it reads 21.???. I do not believe it is dead nuts on the nose at 22mm so if you want to cut hairs and just chew the fat on a chat board, go with 22. Here is a stock 1299 pin and a 1299SL pin. Neither are on the nose to the whole number and im betting yours isn't either. . The original verbiage was referencing wrist pin size not piston pin bore size. Top is stock 1299, bottom is 1299SL slide caliper is a calibrated US Starrett. Can we see a pic of your 22.00 1299 pin?

I don't think Don has a set of calipers let alone a motor to even pull apart? Don thought you had a 1199R now its a 1299? Yeah all Don has done on this board is chewed the fat on here and been up too no good...
 
I have a few Panigale motors. 1198 1285 and soon I’ll have something a lot larger than that

I just rounded up. It’s 21.96 with my calipers. I don’t have micrometer here and the .002” you wanna argue about does not matter to me. I am running a smaller diameter pin and spiral locks in my big motor

And I wouldn’t buy a tool to remove or replace c-clips in the first place
 
Damn thing belongs in a diesel

Or a blown nitro application

You just rounded up? I see so you, like I said, you provided inaccurate information. Thanks for clearing that up.

“smoked”
 
Pretty clear and obvious Don14 has lost his mind this clown has to go or this board is gonna go to a whole new level of horror show.
 
One of the reasons I bought the tool was so that I could remove and refit the liners without splitting the case halves. You can’t really do that without the tool. So I would like it If the tool worked for my application.
