![]() Hi all, new to this forum, suggested by my Ducati dealership.
I have a Ducati monster 400 (import from Japan, essentially a m600) and doing a full tear down rebuild. Just come to taking off the cylinder head and realized I need to get the special 15mm crow foot spanner. As these are not cheap I was wondering if anyone localish had one that I could borrow for a weekend or something. From North Hampshire. |

Hi Matti.
You don’t see many of those about. If you have access to oxi acetylene it is possible to modify a standard ring spanner by bending each end through 90 degrees. I’m sure someone on here has done one recently, but can’t see the post? There’s this though: http://www.ukmonster.co.uk/monster/s...uts#post558724

Torque setting adjustment for crows foot spanners
There's a useful nugget of information in this month's Practical Sportsbikes magazine, which will be of interest to anyone using a torque wrench on a crows foot spanner as above. I'll quote it directly:
"Sometimes you'll need to use a crows foot or dogbone extension to get onto a fastener. In these cases the figure set on the wrench will no longer be the same as that applied to the fastener. You have to do a little sum. Measure the normal effective length of the wrench and the extended effective length. Divide the first by the second (this will be less than one) then multiply it by the desired torque to get the new figure you should set the wrench to. For example: You want 12Nm on a bolt. Your wrench's normal effective length is 300mm. The dogbone adds an effective 80mm. 300 divided by 380 is 0.79. 12 multiplied by 0.79 is 9.48. So something around 9.5Nm is what the wrench should be set to." Every day's a school day! ![]() ![]() |

or use norbar’s handy app
https://www.norbar.com/en-gb/Home/Download-Apps if you turn the crowfoot at 90deg to the torque wrench no change should be needed, as with the bent combination spanner as long as the drive/driven ends are on the same axis |
