Richard,
The original bands were probably spring steel but these are likely to be expensive to source. I suggest using stainless steel as this will have minimal stretch under load and more than serviceable for show and light use.

Steve,
There are suppliers of the oils available but you must ensure you use a straight oil and not a modern multi-grade as these contain detergents to keep dirt in suspension for the filter to take out. The drayton engine only has a strainer filter so will not capture this dirt and can cause damage to bearings etc.

These people carry a lot of specials http://www.martynprice.co.uk/Special_Nuts
This company http://www.stainlessautomotivefastenings.co.uk/ list a stainless steel LH 1/2″ BSW for £5.47
No connection to either company.

SAE oil does not have the EP (extreme pressure) additives. The additives can attack bronze and brass components in some older gearboxes / overdrives where tolerances are critical. No such problems with the Ransomes plus the only extreme pressure gears on the tractor are in the main gearbox which is designed to use the same oil as the engine.

The engine and the main gearbox should be filled with a straight oil, 40 weight is ideal. Do not use a multigrade as these have detergents which keeps any dirt in suspension and as the engine only has a strainer filter (not a paper filter) the suspended dirt would return to the bearings and cause early failure.
Air filter can use a modern oil 0w15 or a 5w20 (lighter the better)
Side drive gearboxes, hubs, load rollers etc. need an SAE 140 oil. (Hypoid is OK)
Following on from the spark plug comments by Rhys the plug, lead and plug cap must not be the resistor type. Copper cored cable is best for a magneto engine.

Dicky,
As identified by Rhys it is probably the speed being to fast but may also be weak clutch return springs or excessive wear in the clutch shoe pivots.

Dicky,
I have already responded to you that the MG5 is not fitted with a Sturmey Archer engine but Ransomes’s own. The SA was only fitted to the MG2.
Regards
Neil

[ransomes256]

If you have an MG5 the engine was not manufactured by Sturmey Archer but by Ransomes themselves as the SA engines were only fitted to the MG2.
I can suppply both dipsticks. drop me a mail at njarrett@btinternet.com
