If the tractor is running ok then leave it alone!

Which model?

Post by WesBrown » Sat Jul 25, 2009 2:05 pm

Is it a 5130 or 5140 or similar? The CAV pump on the 5130 is not simple to adjust, but the Bosch fitted to the 5140 and 50 is a bit easier. If it's an MX, then even easier. Give it a good service and make sure it's fit for some hard graft. If you think it's under-powered take it to someone who has a dynomometer. Most people who think their tractor is down on power find out that it isn't, or it's just a bit of extra maintenance that is required, such as a sludged up fuel tank gumming up the fuel inlet strainer, leaks at pipe unions or such. People want the fuel turning up but can't be bothered to get their valve clearances checked for the first time in 6000 hours. As the Rabbit says, if it running right, leave it alone, especially a Maxxum, a tractor that has faults which occur just as often if the tractor is cosseted or hammered to death.

So the correct metric size to replace 16.9X24 = 540 65 24
18.4X38 = 650 65 38. I have been looking for this information with a while ,thanks for supplying it.

On the front you can have:
540/65 R24
480/70 R24
420/85 R24

If you you have 18.4" rear tyres:
600/65 R38
520/70 R38
460/85 R38

650/65 R38 for 20.8 R38 rear wheels only otherwise you will wind the transmission up!
