1100EVO Cambelt Pully
Hi All,
Just asking if anyone has ever removed/replaced a camshaft belt pully? if so what method did you use to hold the pully in place whilst removing the holding nut? Nothing seriously wrong with the engine apart from the retained nut in the rear belt cover is loose in the plastic. I have a replacement part but looking at it it will need the top pully removed to replace it. I've bought a socket for the daft nut that holds it on but as there aren't any holes(don't think there are) in the pully I can't see how to stop it moving whilst undoing the nut. Any help or advice would be most welcome Thanks Colin |

On the later 2v engines I've seen there is a hole on the other side which you can put a special pin it.

Not sure if these are the right ones: -
https://www.ebay.co.uk/itm/DUCATI-2v...QAAOSwPc9WvJ6S However it says you need to hold the pulley with one of these. https://www.ebay.co.uk/itm/Laser-Too...QAAOSwPc9WvJ6S I suppose the pins aren't designed to take the load of removing the pulley, just to stop the cam turning.

Thanks Darren, I thought the same as you. I have a pair of locking pins but like you I didn’t think they would be strong enough. I also have the laser tool to undo that daft nut but I suspect the outer part of the tool won’t be suitable for the pully on the evo. The outer part of the tool has two pins that should slot into the pully but from memory I don’t think the evo has any. I’ve done a bit more research and it would seem that Ducati list a “special” tool that slots over the pully but it’s unavailable currently. BTW the special tool had a special price of £190!

In a case like that for a one off use, I would make an mdf or plywood spanner for the pully. I could really take my time over it for £190.
Come to think of it a smooth circular "spanner" that fitted the outside diameter of the pully exactly, would grip well enough if it were then split in one place and clamped over the pully. What about gripping the pully with a strap wrench? Not a chain wrench, unless you wrapped the pully up well. It might need two pairs of hands to steady things and make sure it didn't slip? But worth a bit of application to save those sheckles.

You could probably use a strap wrench to hold the pulley once you take the belt off.

Something like this: -
https://www.ebay.co.uk/itm/500mm-Uni...AAAOSw1g1fYuR7 I got a 10 mm and 25 mm one for a couple of quid! Great for opening jars but useful for the bike too. Oil filter removal and I used one to remove the crankcase breather. They're rubber and plastic so no chance of damaging anything.

gb motorcycle products every time for me
https://www.ebay.co.uk/itm/Ducati-Ti...-/110776327575 double check it’s the right fit before ordering he’s very helpful if you have a query https://www.gbmotorcycleproducts.com...mation/contact much better quality than laser ones, which are made of cheese. the factory tools are nice but six times the price.

If your removal tool has 4 pegs to fit the special nut and a half inch square drive an electric rattle gun undid mine, belts were left on for this operation but were due for replacement anyway so I was not too bothered if they got stressed in the process

You're right about not using the pins Darren mentioned to lock the pulley, they'd probably shear off as the nut is tightened to 71Nm. Also, as you surmised, the Laser tool, (and the one in slob's post), won't work on the later pulleys as there's nothing for the socket's pins to locate into.
The factory locking tool is 887133152 and I don't think anyone makes a direct copy. However, Biker's Toolbox do list a similar tool. https://www.bikerstoolbox.co.uk/acat...ine-Tools.html Although they don't show the Monster 1100 Evo in the fitment list, they do say it fits the Hypermotard 1100. The tool looks the same as one from HDESA and they do show it as being suitable for the Evo. https://hdesausa.com/collections/des...ing-wheel-tool Since the Hypermotard and Monster 1100 Evo share the same cam pulleys, it seems likely that the Biker's Toolbox one would work. Whichever method you use to lock the pulleys, do follow 350TSS's advice about using an impact wrench - it definitely makes the job a lot easier. |

I have plenty of old belts lying around, might try making a new holding tool from a piece of belt and an ally bar |

Surely not Jerry if the belts are off and the pistons are at the bottom?

You'd have to be unlucky to do so. If piston at top then it could.
