hello
i just bought a massey ferguson 35? with a 4 cylinder engine
its grey and red, but i notice that the original colour was grey and gold

and how can i find out which model i have
thanks

if its a grey & gold it is a 56/57 year. The number is found below the water temp. guage on the front panel. The year is found on the engine block on the right hand side behind the steering arm.hope this helps

Have a Grey and Gold FE35 serial no SGF43592,2 owners since new
has been looked after like a baby,I think I must have been the
first to have the tappet cover off,as the clearances varied
from 4thou to 16 thou.
I take from your specs that the petrol is the same valve
clearance,I am sure their is not a mark of a screwdriver on
trying to set tappets,if you could confirm they are the same
I would be ever thankful
I have a MF 35, which i have just gotten. I am trying to find parts but not sure what numbers i need off of the engine or transmission or even where to locate them. Can anyone provide me with any information, it would be greatly appreciated. Also, where can i get parts for this, i have searched the web and every where i have looked or called they say the parts are no longer available.
Hi Michael,
The most important number is the serial number. This is printed into the plate on the dash panel – right hand side, just above your right knee as you sit on the seat.
There are plenty of suppliers of parts. Massey Ferguson still provide many of the parts if you are looking for genuine parts from their network of local dealers. Otherwise there ar companies such as Southern Counties Tractor Spares, Agriline Products, and lots of others.

i have a 4 cylendar 35 that has been found in a bad way there are no data plates except a tiny peice on the right hand side when looking from the seat which has the number sdm93766 stamped on to it can this and the engine number be used to age it.
Hi Rob,
Just take a look at the Massey Ferguson 35 serial number page.
That would make yours a 1958.

dear vintage tractor engineer
i have just got your engine overhual dvd in the post. i have found this very helpful. As I am only 14 my mechanical skilss are slightly lacking but your dvd has given me the confidence (with a little help from knowledgeable grand fathers)to rebuild the clunky engine of my mf35. But there is one problem the engine on my tractor is the 3 cylinder perkins engine. so i wondered if you have the data specifications and torques sheet for the 3 cylinder perkins (like the one above). if you dont do you know where i can get this information.
many thanks for a great dvd
