Just a little update. Both sets of adjustable rollers and both fixed rollers came out with no problems what so ever. Nice easy progressive force. Starting to look better already! I am going to see if I can get the adjustable bearings from work before buying them, (found them at £3 each approx), the fixed bearings have an SKF number on the bolt head but are proving more difficult to source (I see a lot of other people have had the same problem). Anyone found them for cheaper than Ducati prices? Cheers
Well Done Stew, you have obviously got the magic touch !! It does not look half so bad now the fur is all off ! Nice use of welders clamps, you must be a power station guy !
S'better! I would at LEAST - pop the heads off tto check the barrel condition & do the shims etc? Dunno where to source the fixed roller bearing from? What do the old ones feel like? A little *crunchy*? ** loving the belt clamps!
I recently acquired the complete set of roller bearings from Baines Racing at Silverstone, give them a call as they'll post out parts. From what I remember all four came to something like £50.
Haha - Not a power station guy (Engineer), just have the clamps in the shed, they did the job. Yeah, the heads will definitely be coming off next for inspection, cleaning and painting. Here's a question that I was thinking of starting a new thread with but will test the water here; Does any one run with the belt covers off, and to take it one step further - does any one run with (or know anyone that does/had) the rubber 'surrounds' off as well? I am aware that this would pose a slight issue with timing marks, but other than that what is every ones thoughts? (I am aiming for a raw, Cafe-ish, naked look after all).
Also, the fixed rollers don't feel all that bad, it's just the surface finish and general condition that make me want to replace them.
Yes. :smile: Run for nearly 2k with no issues? Belt tension checking is done in minutes, the bike runs a bit cooler due to the lack of vacuum cleaner parts bolted to the heads & barrels & you have more whizzy-bits to look at whilst the bike is running as well as the clutch? Would'nt recommend doing it if you live down a farmtrack or other rural area with lots of road debris etc, or do a lot of wet-weather riding (although it doesnt bother cars?), but looks amazing compared to the standard covers? I think one of the blokes on ducati.ms took his surrounds off - the only drawback would be the lack of timing marks??
Very nice! Like the exhaust tape too (definitely planning it myself), and the little white marks on the belts - superb. Couldn't agree more, being able to see the mechanical witch craft is strangely satisfying! The only reason I'm planning taking the surrounds off is that with them still on it looks like something has been taken off, if you know what I mean, as you can see the bolt holes. Thinking off 'projecting' the timing marks to a suitable location.
Im not conversant with whats behind the surrounds so couldn't say what you could make a timing mark on, per se? The empty bolt threads could be filled with a stainless flange bolt, like these?

Now it can BREEEEEEAATHE! :wink: Can't be dealing with cleaning exhausts every ten minutes, its not a Hardley.
what dya mean it not a hardley its a right tarts handbag-goes with tha tassels and conchos on yer jacket:biggrin:
You'll have a bigger issue if a stone gets trapped between a belt and a pulley I recently removed a couple of fixed pulleys and found them to be cemented in with blue Loctite and they were hard to get out, and incidentally the fixed pulleys come apart and there are 2 smaller conventional bearings inside. That internal circlip might give you some problems though :wink:
I would be inclined to keep covers on, or source covers like 470four......the front one and the respective rubber bit tend to keep water and grit away from the camshaft oil seal....if water then gets along the shaft (like it did on mine) it can cause a few serious issues.... AL
Was going to ask the same question about the bearing being pulled / pushed. I VERY rarely ride in the wet if at all avoidable, but am now just wondering if the aesthetics are worth the (probably small?) risk of any issues caused by no covers.
Harleys? BIG rear drivebelt to the back wheel? LOTS of stones being spat about at one time or the other, but they seem to cope? :smile: Did a lot of google searches before taking them off, although there is a lot of Nannying re: "You'll get a stone in there!" no-one seems to have had any issues?? My favorite quote was from a Sport-Classic owner with no belt covers getting stick from another rider for being coverless? He offered his pack of peanuts to the verbal assailant & offered to start the bike, would refit the covers if he could managed to put a peanut through the pulley-wheels? The rider declined the offer and walked off. :wink: Its a 17-year old bike & will probably give me grief at one stage anyways, if for any reason it does pop a belt then I'll have it apart and back together no prob. Coverless I can easily check their condition, tension, bearings, if one ever did go fluffy then it would be easily seen and rectified.
Part 35 in the exploded diagram, is that a nut as such? Like a bicycle wheel or pedal bearing cone? Does the bolt screw into it to hold the lot together? Shouldnt be too much trouble to strip one down,I always assumed they were sealed as such.
I don't know, I hadn't seen this diagram at the time and couldn't figure out how it cam to bits. :frown:
Looks like a wheel-bearing arrangement? Get the bolt & nut out of the middle, then tap one out of one side through the middle with a drift, same for the other side? Circlip stays where it is!
Just to update: The cam pulleys were subjected to a bit of electrolysis and came up not too bad! Gave the horizontal cylinder head a bit of a clean too.
