MF 35 or 35X - what do I have

I bought a second MF 35 tractor last summer and I am trying to figure out what I actually have. 35 or 35X.

It's a 1964 MF 35 3 cylinder Perkins. serial number
SNMY 353514. Number stamped on the block in front of the exhaust manifold near the water pump elbow on the left side of the tractor is 19A9797.

This number is not cast. It's been stamped with punches.

The tractor was re-painted and the original stickers painted over on the side of the bonnet. New stickers were put over the old painted ones but appear to be about 6 to 7 inches shorter as if the wrong stickers were installed. The current stickers just say "Massey Ferguson 35"

It has the locking differential, dual clutch, deluxe seat. The starter is original from what I can tell with CAV Made in England stamped on it. The solenoid is not on the starter but rather mounted on the tractor in behind the air oil bath cleaner.

The tractor has a instrument panel that only has the Oil gauge, Tachometer and Ammeter gauge. I have read that the 35X has a higher rated tach at 1700 RPM instead of the 1540 rpm that are not 35X. I will look at the old Tach to confirm as I replaced with a new one and not 100% sure what it says.

I also read that the bracket for the Dynamo generator is different on the 35X and from the description of what I read "the MF 35X has a bit of flat bar bent into a long E (the middle leg missing) with two bolts on the front casing, fitted diagonally." From this description my generator has this bracket.

Can anybody confirm this is actually in fact a 35X. What does the X stand for? Is it Deluxe?

Thanks

Scott

Does it have a 6 volt, or 12 volt electrical system.

Does it have multi-power.

Hello,
Almost as a rule any 35 tractor having a differential lock pedal can be regarded as an 'X'. It is also possible that
perhaps the differential pedal and other requirements were added at some time. The starter motor should have been
made by Lucas-CAV. It is extremely unusual to find one with a separate starter solenoid. This may have been a
requirement for the US market. All UK produced MF 35 3-cylinder starters had the solenoid mounted on top of the main
starter body as an integral part.

I was with my Father in 1963 when he ordered a new Massy Ferguson FE 35 X. The tractor is S# SNMY320137. S>Standard/Utility Chassis: N> Perkins Diesel: M> Dual Stage Clutch: Y> Differential Lock: 12 Volt Lucas system. The Starter is the original and has NO external electrical Solenoid.
On a machined Boss (on engine) there is the number 1968212c stamped. The number(1968212c)is used when ordering any components for the Engine. The # cast into the Engine Block is 152 UA....120416D. This tractor has Grease nipples machined into the front Wheel hubs,(caps that thread onto the front hubs). The Tachometer indicates standard PTO speed is at 1700 engine RPM.
The fuel pump is a CAV with fuel injectors having orifice sizes of 0.0157.Pressure setting of 1835 NEW and 1760 USED. The Tractor was ordered with 24" rear tires and rims.
Tractor cost $3,300.00 new and is a daily runner from May>November on the same property that it was purchased to work. I'm thankful we still own and operated it!

The 35X should have the number GKN1523N stamped into the block just above the oil pan under the generator. The higher rpm, more hp engine is the only thing that makes it a 35X according to Vintage Tractor Engineer.

12 Volt

Not multi power

This is a UK made tractor.

Where is your solenoid attached?

I already replaced the Tach but cannot remember what I bought. I know when I checked the AGCO parts diagrams and listing that I used my serial number to get the correct part number which I later cross referenced with SPAREX. I'll go to my fathers garage and have a look at the old TACH that we kept and the new one also.

I'll check the wheel hub caps but I'm pretty sure it had grease nipples.

The injector pump was replaced but the guy that sold us the tractor last summer still has the old one and I can get it to verify also.

Thanks for the help.

Located in Moncton New Brunswick Canada. Spend the winter in this cold country. LOL

Does the area look like this where the number is stamped on a machined section? Mine was on the left side near the water pump elbow

The stamped number should be on the block just above the oil pan, and below the generator. If TractorData.com is correct the UK built 35 has a 6 volt system while the 35X has a 12 volt system (2, 6 volt batteries). The US built 35 has a single 12 volt battery system.

With the generator (dynamo) bracket your tractor has I would bet its a 35X.

Our FE 35 X arrived from England with a CAV STARTER as per PICTURES:

CRANCKING of the engine became (low to no rpm from starter) hit and miss!

The STATER was REMOVED(1973)from the TRACTOR. It was discovered the RPM was not engaging what appears to be a DEVICE to add more CURRENT into the FIELD windings? to achieve greater torque after the STARTER has engaged with the FLYWHEEL? A new internal device (current router?)was replaced (1973).

On or about 08/21/2015 once again I had the same starter (CAV) issue:

With NO parts available readily, I purchased a NEW starter with SOLENOID mounted on top of STATER as per the pictures...not a CAV type: An original CAV STARTER from ENGLAND was quoted at $700.00 + dollars! This included delivery to western Canada.

I prefer a thread on oil filter over a cartridge filter. As per the photo an adaptor was purchased from the YT site.

BELOW is INFO supplied by "ptfarmer" when I was looking into STARTER problems on my FE 35 X on 08/21/15.

From what I understand a newer starter that has the nose cone will not work (a newer starter with a nose cone hits the transmission case from what I've heard). This is the only place I've found that can work on the obsolete CAV starters:

We have the same starter. Ours still works fine but I'm glad you brought up the issue with a new starter with nose cone not fitting in case ours quits.

Mine was built in the UK. I guess they did have the starters without the solenoid attached.

Mine also has the new screw on type oil filter.

Do you have a pic of your Tachometer where it shows the 1700 RPM.

Here is a pic of my old one and a pic of the new one I replaced.

Does yours have the hour count for 1500 RPM?



Mine also has the grease nipples on the front wheel bearing caps

We have the grease nipple bearing caps also.

Do you have a pic of your tachometer where it shows 1700 RPM.

I bought a replacement tachometer see pic below and a pic of my old tachometer.

Ours only has one 12 volt battery and the ground is on the negative. One batter tray beside the fuel tank. If the original had 2 six volts then I suspect someone changed that in the last few decades.

I could not find anything under the generator and above the oil pan. But on the other side next to the oil filter I found the exact same numbers as yours but it is cast into the metal. See pic below

So what does mean? Does my perkins have more horse power since it is an upgraded version of the 3 cyl perkins? What are the differences compared to the older perkins? I know it's not the D version as these only came out with the 135 and direct injection.

This is my generator bracket

Here is a pic of the injector pump. Not sure what to tell from the tag. It is a replacement to the original and I wasn't able to get a view of the original yet as the previous owner still has it. But this replacement I believe is a CAV type as the logo is very faint and not showing in the pic.

What do all these numbers mean on the tag

The info I got from VTN could possibly be wrong as to where the number was placed, or how exactly it was "stamped" into the block (I've been looking for other write ups, and hopefully a picture, or two when I have some spare time). On the a3.152 the injectors are straight (up / down) into the head while the ad3.152 the injectors are in at a slight angle.

35X has a diff lock and an internal hydraulic filter.
