For some reason my old engine had a cut and spliced oil line to the cooler, which failed during a special stage of the Beacons Rally, resulting in the engine being run at full noise for a good handful of minutes with no oil.

I can only assume the mechanic I paid to put in the previous engine decided this was easier than unclipping the oil lines properly. Lets not go there.

Anyhow, 10 months down the line and it starts rattling - maybe just little ends but whats going to fail next. Time for another engine swap. What seems a good engine was supplied at a very fair price by MrDucatiParts of this parish and a plan was made.

Reading a few threads revealed this is a daunting task for a desk jockey without even a garage to work in.

No worries, a mate with a workshop and the promise of some rather fine hospitality with a bunch of airhead fans gave me the impetus to give it a go.

Having a good workshop made it possible. A decent strong hydraulic lift like the small blue on under the bike and either a hoist on the ceiling or an A Frame / engine lift would be the minimum set up to do the job.

So it went like this...

I cheated with a very nice workshop:



Take all the obvious big bits off



Keep going till you pretty much have the engine, gearbox and clutch and shaft plus the frame left. You will see the frame has two halves, front and rear.



Do not disturb the horrible cable junction box under the battery tray. Do label all the cables so you know how it all plumbs back together.



Stick a couple of random bolts into the two halves of the frame where they join so the bike can pivot on these, and get some mechanism to lft the rear of the frame in place.



Lift the back frame section up and out the way and 6 bolts drops the clutch, box and shaft as one un-disturbed unit.



THen basically lift the back and front together to leave the engine behind ready for the swap out. I cheated and had a second pulley for the front. What luxury!



Then its just a question of reversing the process. I used a clutch alignment tool I borrowed off MrDucatiParts, and that was the only special tool I needed.
 
If I won the lottery, someone else would be changing the engine:D

Good point. Maybe a team of those calendar lady mechanics who never seem to have rags handy and have to wipe their oily hands on themselves. I'll just sand by with the swarfega :)

She could lube my driveshaft any day of the week...:drool

Methinks he may develop an Inspector Dreyfus type twitch instead of "Clouseau!" There's be mutterings of "Dirty Bits!"
 
Sadly I left it more than 60 mins till an edit to add a few more bits so if a mod wants to merge this in then please do..

Its Ducatiparts.110mb, not MrDucatiParts by the way.

So label the cables etc and dont disturb that cable junction...



I did drop the fork tubes etc as I wanted to replace the ball joint on the wishbone, otherwise I think you could certainly leave all that assembled which would save some hassle.

This was a comedy moment when the wooden plank we used under the new engine stopped us getting the front wheel in. Easily fixed with a saw.



The home straight now, looking good...



Sadly I goofed on the final furlong and trashed the big o-rings that sit in the valve covers resulting in oil pissing out when we ran her up. Lesson learnt, the o-rings go in the cover, not onto the engine during re-assembly. Just goes to show how mechanically inept I am. With no spares available Saturday afternoon we were thwarted.



But she ran up fine and I took her for a little spin to the end of the lane and the engine felt sweet. My trainers are now pretty waterproof. So I'll hopefully find some seals today (Monday) I'm sure, fit them tonight and take her for a spin.....

Big thanks to all who helped out.
 
Any pics of the oil hose?

It couldn;t just have been age and infirmity under pressure ?

I admit I'm getting on and was at times infirm under pressure, especially on the Friday when I wanted the bike finished and off the ramp for the airheads to use on their bikes, but I dont think that came into play.

The line had been cut, a steel tube inserted and two butterfly clips used to keep it all in place - which worked until tension was applied when the beak became loose and flapped around a bit.

As I started the thread I kicked myself for not getting a piccie.
 
Just a quick update. Replaced the oil seals in the rocker cover and all is good. Oil tight and runs sweet - noticeably better than before. It looks like a tidy engine and well worth the hassle.

Thanks again, Sid.
 
We all saw it. No confusing, it was a cut and shut, complete with clamps.

Oh dear! Shakes head and walks away, muttering, "why would you do that the clamp is inches away on the hose and the bottom is a big banjo ????" :blast

Good Job You got Sorted Mike
