Triumph Trophy Engine Strip

[Bender]

I see you taped over it. So that's victoria's secret.....

Good job and nice pics

[onesea]

As a fellow trophy owner following with interest. You know there is a FB trophy group full of wisdom...

Do you mind if I share this post there?

 

No worries about you sharing it, I’m not on Facebook so unfortunately can’t partake of their wisdom, If I get stuck would you be ok to pass on a few Q’s ?

I think we have done this before.. no problems..

[Tango]

I'm assuming that the valve clearances were all ok before?

[Tango]

Yes, a pair of mechanics anti cut gloves are worth their weight in gold, mate......saved my hands from all sorts of carnage....

I did the shims when when I took the cam cover off to pretty it up.

Yep, coolant, Swarfega & anti bacterial gel stings a tad

Yes, alcohol hand gel is a good way to discover all the little cuts that you previously hadn't noticed!

I do remember it yes...ahhh the school nurse she was a horrible old bat

[Mickly]

Right, I’ve managed to get hold of some suitable gloves to stop my softy office worker hands from getting cut up.

“If Madam would like to bend over for a minute, I’m sure we’ll get to the bottom of this”

[Mickly]

So off with the end cans.

I thought this bolt was a bit close to the swinging arm.

And sure enough

Can you polish out scratches from powder coating? If so what’s best to use?

I’ll have to adjust them better when I refit.

All packed away

[Mickly]

Taking the headers off

Firstly, the Trophy ( & I think all the early Triumph 4 pots ) has a support bracket onto the back of the sump housing, this was broken when I got the bike so a new one was added,

This is the bolt you have to get to under the bike.

Luckily as I’ve had it all apart once, it’s visible & not covered in crud !!

Blocks of wood supporting the down pipes

Nuts were easily undone on account of me cleaning the threads, using new nuts, washers & copper slip when I originally reassembled it. So all done with bits of old rag stuffed in the head to stop anything getting in there.

You can see where the crap Simoniz VHT paint has flaked off.

This is the bracket that supports the headers to the sump.

Unfortunately it’s on the LH side which means there’s no room for adjustment to take the silencer mounting bolt away from the swinging arm, I may have to heat & “tweak” the outlet a bit, dunno if this is a common problem ([mention]onesea[/mention] )

Exhaust fixings bagged up - these money bags are really useful for storing small stuff & they are free from your bank

[Mickly]

Time for the carbs to come off.

1st the coils & plugs are removed to allow for better access.

The extension bracket drops the coils a bit to allow the CRK tank more room.

Coils removed & paper towel stuffed in the plug holes to stop any stray bits falling in.

Undoing the rubber clamps to the head

But when I wiggled the carbs off, the rubbers stayed on the head and came off the carbs - hmmm where they not secure enough? Did this add to the potential lean mixture issue? Must ensure they’re all tighter on reassembly.

Pulled the carbs to the left to get at the throttle linkage.

The bottom nut needs removing so the throttle cable can be slipped through the slot in the top bracket, then the nut is reattached to stop it getting in the way.

The throttle cable barrel nipple is freed by passing the inner cable through this slot in the linkage ( sounds so easy doesn’t it? But it’s fiddly as hell!! - you need 3 hands & X-ray vision)

Carbs off & paper towel stuffed into the rubbers to stop stray stuff falling in there.

I need to redo the fuel pipes as the fuel tap on the CRK tank is on the other side to the std Trophy.

Drained the remaining fuel out, stuffed them in an old pillow case & boxed them up.

[Mickly]

In order to get the chain off the front sprocket first the clutch release cylinder must be removed.

Bolts in order in which they fit as a reminder.

Cylinder off & zip tied to prevent the piston coming out

No sign of any leaks

Cylinder is now tucked out of the way & the fixings bagged & stored.

[Mickly]

Gear change linkage removed

 

Couldn’t quite get a socket on coz the ratchet or extension Gould the frame - 8mm ring spanner did the job

Linkage stored away.

[Guest Swagman]

Looks to be going very well up to now.

[Bender]

Do you not have a flexi drive/jointed drive for your sockets?

[Mickly]

Sprocket cover bolts out & arranged in order

Sprocket cover removed - needed a bit of gentle persuasion from the back ( piece of wood & a hammer ).

You can see that the oil filling plug / dipstick is part of the cover, therefore there’s an oil way incorporated.

So if you ever want to check or remove the front sprocket, you have to drain the oil & replace the gasket.... thank you very bloody much Triumph !!

Sprocket cover now boxed up with its fixings

[Mickly]

Chain needs to come off next.

Pinch bolts slackens off

Rear axle spring clips removed, bagged, labelled stored.

Axle slackened off - note it’s a Torx fixing & multiple adapters to fit to my breaker bar.

Slip chain off front sprocket ... Noooo wait, the bloody sprocket has to be removed as there isn’t enough room for the chain to slip past

Sprocket retaining washer with cold chisel

Tabs hammered flat.

Chain to be retightened ( all the parlava at the back axle ) so I can stand on the rear brake while undoing the sprocket nut ( not having a rattle gun - which is why taking off the rear brake pedal to access an engine mounting bolt is the NEXT step which reminded me that I don’t have a 36mm socket & borrowed one last time !!

[Mickly]

So, a 36mm socket acquired from Halfords via click & collect ( all done in under an hour )

 

Sprocket off but the chain still won’t slide past the spline

[Mickly]

Removed the chain guard ( non standard )

Slipped the chain off the rear sprocket, a bit of a wriggle & it’s done.

Zip tied the chain up to stop it dragging in crud & attracting gritty stuff

Chain guard wrapped & boxed with its fixings

[fastbob]

How did you get the front sprocket nut off ?

[Mickly]

How did you get the front sprocket nut off ?

 

I got a 36mm socket from Halfords ( see above )

Tightened up the chain & rear axle, put my foot on the rear brake lever & used a long breaker bar.

[Mickly]

Disconnected the wire to temp sender on the cylinder head

Disconnected the wire to the neutral switch ( bit blurry )

I undid the starter motor cable

& promptly dropped it into oblivion...

Was gonna remove the alternator anyway to repaint

Un-clipped the alternator harness connector

Removed the alternator ( the earth uses the top fixing )

 

The lower fixing is a bit hidden away

There’s the starter motor cable nut.

Removed the starter motor & filled the holes with paper towels to stop any debris ingress

Starter motor & alternator stored away with their respective fixings

Oil pressure switch disconnected ( rear of sump )

Hi [mention]Mickly[/mention] seeing you taking the chain off reminded me of something that can go wrong with those spring clips.

Please make sure when you reassemble that the grooves are clean and the clips seat well.

It is the same system as kawasaki and the photo below shows what happens when one goes awol and vibration affects the nut.

Before anyone says anything the axle was very well torqued up but vibration is a very powerful thing.

 

 

This was very much a brown trouser moment as it happened at 80 whilst overtaking a guy on a BMW and felt for all the world like a blowout.

Result slight bend in swingarm and a lot of faffing about replacing.

By the way the allen key is being used in the roadside bodge to get me home lol not left in there.

Hope thats of help.

Cheers

Ian
