Swingarm pivot bolt removal

[Spjallen]

Hello again. Just aquired a nice alloy swing arm, but how do you remove the pivot bolt? Do you need some overpriced use once only (hopefully) ducati special tool??

If you mean the pinchbolts they are just 8(?)mm hex socket bolts and then the spindle just drifts out.

Unless you've bought one where the chain has been loose and has knackered the left hand pinchbolt head by peening it over and filling it with alloy swarf so it wont turn in the recess.....

Took me 4 hours to salvage mine with cunning use of drills, drifts and a big hammer!

[Spjallen]

Is that all that holds it on? Those two pinch bolts?! Do you just knock it through with a drift?

Unless it has the circlips on the end which will need to be removed from one end first, then drift it out and try not to damage the shims

Thank you. More scary stuff happing in my garage tomorow then!:eek:

hey if I can do it, anyone can!



Oh no, hold on, Snells did mine :D

Lightweight!! Do I need to change my axle axle? Current one seems too long. Too may axles!

Are you talking wheel spindle axle, or swing arm pivot spindle axle?? :confused:

[paynep]

If its an axle axle, then he means both.

Or that could be why its twice as long as it should be!

Don't know about SS but the St one which went on my monster needed a longer axle, although swing arm pivot was ok

[Spjallen]

Pivot is fine as long as I don't use circlips on the ends. The oem steel swinging arm held the pivot bolt in place with those. Seems the alloy arm is slightly wider. The rear axle looks too long. I'll have a play tomorrow. Thanks for all the comments. Shim of a job so far!!

Simon which Alloy arm did you get, there are three different ones that I know of to fit the 20mm spidle on the back of the engine. I'll rule out it being the latest one, making it either the early one with the adjusters inside the swing arm and the adjusting bolts sticking out of the end plates as they did on the steel swinger or the more common alloy arm found on most 900SS's with the adjuster blocks on the outside pressed up against the adjusting bolts

Kev, it's a 750 ss alloy one with more normal style chain adjusters - bolt and lock nut type, not the ones that fall out of the ends! The pivot bolt on my steel ss one had circlips on both ends, but to make this one fit I've taken off the circlips and it's now flush with the swingingarm. Seems ok but not 100% sure. The lower suspension bolt also was different but with a different - slightly longer - bolt it seems ok too. Just left with finding the tq settings for the pivot bolt clamps and making the rear axle fit. Which I don't think it does, maybe too long or needs washers.

Pretty sure that's what I did with mine when I converted it!

Thanks. Now I know who built this bike, I must have read the story quite a few times before I took the plunge of DD. Great looking bike and brilliant write up.

Swingarm is on now. Found out the pivot bolt clamps tq it's 37 nm. Measured the rear axle it's about 6 mm too long. Are a few washers an acceptable answer to this problem?
