I had some Wriggly seeders. I think they were designed for carrot or similar.

Iain,
Well done for getting another MG back and running.
If the tractor was running on solid ground / concrete it is common for fuel to flood in the carburettor. The main reason for this is the stroke of the engine and no suspension. As the tractor bounces with engine stroke it knocks the float up and down and therefore the needle off the seat letting excess fuel in.
It may still require the needle to be lapped in with Brasso or similar fine gritty polish or even a new needle which would still benefit from lapping in. If the float is dipped around the complete flat area I do have some extra long needles to compensate. Only suggest float replacement if it leaks.

Geoff,
If you think your surprise is unusual think about this.
Just over a year ago I received a parcel containing a magneto and a carburettor which I presume someone wants me to overhaul. There was no letter or sender name or address in the package and nobody has made any contact to ask why I have not sent them back.
How long would it be deemed acceptable to offer the items for sale? Not in my nature!!

Dave,
Welcome to VHGMC.
I am the the supplier of new spares for the Ransomes and I am sure you will find many owners willing to offer users advice.
The machines are extremely robust and will easily run a saw bench and if maintained are very reliable.
If I can be of assistance with parts please contact me directly. njarrett@btinternet.com

Iain,
I went for CDS Thick wall hydraulic tube (also not cheap) in an attempt to reduce the overall machining required and avoiding the need to harden as it is pretty tough and will also work harden a little during use.
I have costed the rollers at £1:75 each and the pins and nuts at £2.00 each which I am sure you would agree is a fair price when taking material cost and time into account.
Just need to sell some now

Iain,
A bit late for you but due to current requests and demand I have just completed stock of 600 wheel rollers and pins which generates an awful amount of swarf and appreciate the effort involved.

There are no paint codes available but the blue is virtually the same as Ford Tractor Blue (not Empire blue) The red was Rood Red which is virtually the same as the old Massey Ferguson Red.

Regards and Happy New Year
Neil

Iain,
Not sure why you consider your serial number may not be correct.
If the number is 7156 the tractor would be circa 1951

However I do not understand the 2155 from the gears. If the gears are marked 2/55 it would relate to February 1955 which does not match the serial number as this would relate to MG6.

Jonathan,
SAE 20 and even SAE 30 seem a bit thin to me. Surely this oil is for the Diesel engine with a roller bearing big end rather than a petrol engine with a plain bearing.
Neil

[ransomes256]

Yes the engine sump and the differential use the same oil.
The side gearboxes, hubs and rollers all use Hypoid EP140
The air filter a light oil like the modern car engine oils 0w30 or similar.

[ransomes256]

The gearbox oil is a straight SAE50 Engine oil

It sounds like your drive wheel rollers are much to loose on the pins.

The outside diameter of both the drive and idler wheels were originally 18 1/4″
The PCD of the drive wheel rollers were 17 1/4″
The drive wheel rollers 15/16″ diameter with a bore of 1/2″
The pins were 7/16″ diameter. (I would use 11mm stock)
The rollers were hard (probably case hard) and the pins were soft but from a tough steel.

The dimensions will depend on which age of MG5 drive wheels you have as they changed during production.
Do you have the semi circular reinforcing braces on the drive wheels?
Can you get a rough idea of the diameter of the 15 individual drive rollers and I will advise.

Robert,
MG6 on ebay now.

Nothing to do with me

Stew,
Here lies a problem.
The Ransomes MG crawlers are not supposed to be greased !!
All the points on the machine are for oil (normally a thick Hypoid 140)
So as wristpin states oil or grease is better than none is in the case of the crawler not true.
The oil seals on the hubs and rollers are installed backwards and designed to burst open when oiled to push any dirt out of the lip then close down to seal then any mud pushing on the seal will only force the seal down more rather than open the seal and enter the bearings. Grease will burst the seal open then hold it open allowing the dirt in. Additionally the way that the side gearboxes work they only have a little amount of oil in which is splashed around by the main hub gear which then lubricates the pinions and bearings which will not happen with grease.
Additionally the main gearbox uses a straight engine oil (SAE50) and not a gear oil.
