Triumph T10 fly wheel extractor (61-5040)

Triumph T10 fly wheel extractor (61-5040)

I recently managed to source an original Triumph T10 (& Tina) fly wheel extractor 61-5040 as pictured here. I managed, with some difficulty to remove my fly wheel without this but managed to break one of the fragile fins in the process (I glued it back on as good a new). While these tools are as rare as hens teeth, if you do manage to get one you will find engine disassembly a lot easier.

Tina & T10 Wheel Hubs – Optional

Wheel Hubs – Optional

The wheel hub caps were an optional extra for both the Tina and T10. They are, like most things Tina or T10 related, rather difficult to get hold of. However, it might be possible to re-appropriate or make some hubcaps based on the following dimensions.

Speedo head – is the drive seized?

Speedo head – is the drive seized? – By forum member Babrat61

If your scooter has been stored and unused for many years , as most out there appear to be, it is worth checking the square internal drive to the speedo is not seized. Fitting a new speedo cable without doing this may result in an immediate failure of the cable inner!

I have accumulated 6 speedos and all were seized!. The internal pinion and worm gear are nylon and are lubricated during manufacture with a white grease. This grease solidifies with age and ‘gums up’ the drive spindle (which the small square section inner of the cable slots into) and the worm and pinion gears.

To unseize the mechanism I recommend converting a small square needle file, by grinding the square down to suit the internal cable size, clamp the needle file in the vice horizontally, slide the speedo head drive spigot onto the modified needle file and the gently rotate the speedo in a clockwise direction. It will be quite stiff at first, but as more rotations are made you will notice a gradual freeing up of the drive and see a deflection of the speedo face needle and after enough revolutions an increase in the odometer. It may be necessary to rotate the speedo up to an indicated 1 mile on the odometer to ensure a super free mechanism.

Some freeing spray may be directed into the square drive of the head, hoping that some leeching of the liquid will occur to help in the freeing up process.

Once you can rotate the needle file freely in your hand and see the speedo needle bounce up to a speed and back again, plus a gradual increase in the odometer reading, it is safe to say that the speedo is functioning satisfactorily.

Under no circumstances try to disassemble the speedo, as the front chrome bezel is crimped on at manufacture and is unlikely to come off without a fight and it certaily won’t go back on again with any degree of satisfaction.

The Front and rear pulleys of the Triumph Tina and T10

Front Pulley

The front pulley is an automatic centrifugal clutch that drives the rear pulley via the belt. The front pulley is similar in design to other centrifugal clutch systems, in that it has a numbers of weights placed between two plates which when rotating push the plates apart and thus engage the clutch.

I have taken some pictures of the reassembly of my front pulley to show what goes where as it is a complicated layering of parts that make up the clutch.

1. onto the bare spindle goes a small spring, the cog (shown) and, importantly, two semi-circular retaining wedges. Be very careful not to lose these wedges!!!!

2. Next goes the back plate and two washers as shown

3. Then the bearing

4. Followed by this central thingy-me-bob (yes, that is the technical name)

5. Over the top of this goes the clutch back plate and with the weights placed

6. The front clutch place goes over this and the weights should all nestle into the clutch housing neatly. This is all held in place with a screw over the centre spindle.
Not shown here, but there should be 3 push springs slipped over the 3 protruding poles that will eventually hold your cotter pin.

7. Then the clutch cover (in this case i have sprayed mine a rather fetching shade of red) and fit 3 new cotter pins as shown.
Pushing the cover over the springs and placing the cotter pins is quite fiddly.

Triumph T10 Tank & Fairing Bages: Resources for printing your own

The T10 comes with a moulded plastic front badge mounted on an integral black rubber backing. Unfortunately if you don’t have one of these you would be very lucky to find one as a spare part. Here is a picture of an original front fairing badge:

Also on each side of the fuel tank the same badge is displayed but as a simple tranfur decal.

Obviously, if you are repainting your T10 you will need to get replacement decals. We have created the art work for you to be able to get these printed.

Dimentions: 100mmx55mm

If you do print a run of these please let us know how they turned out.

T10 body work home sprayed with Vauxhall Leaf Green with Triumph decals both sides.  The decals are sprayed over with about 3-4 coats of clear lacquer. Obviously this is a non original colour but looks pretty cool. I have finished of the top and front frame cut out with rubber edging that can be bought from Frost Classic Car Restoration by the meter. The original trim is chromed effect plastic.

A stripped down engine block from a Triumph T10 – 1967 (shown without piston)

 Engine block needed a long soak in a bucket of engine degreaser. The poiston block and piston are both suffering from scoring and the piston need to be replaced (Hepolite 15957) and the engine bock needs to be honed.  The Crank caseafter being split and new instant gasket added to reseal the two halves. Luckily the piston rod and barings seemed fine. There was little to no side to side movement and as such was an easy overhaul.
