Massey 35 petrol

Hi everyone,

I have a 1958 straight petrol Massey Ferguson 35 which I have recently bought, it has stood for a few years in a barn so under cover and dry. On initially getting it home everything seems complete, oil looks a good colour and turned over freely on handle. I was having some issues with the electrics draining down battery when trying start. Out of the blue the engine locked up, I removed starter and managed to gently pry it the opposite way and it freed up. On removing the rocker cover I found a stuck valve and one of the pushrods had popped out and was stuck. After freeing this off and the stuck valve the engine then rotated by hand nicely no noises no lumps or bumps. Tried spinning over again on starter and it has locked again, any ideas? I was wondering if possibly a governor weight has become dislodged
Kind regards Harry

English "Standard Engine"..?? or Continental Engine..?

YES, the STANDARD engine has a history of dropping Governor weights after many hours of operation.

Standard engine on this one, later 12 V block, I have pulled all the plugs out and put some oil down the bores, it then spins over very freely on the handle. I re-fitted starter and tried it numerous times on starter with plugs removed and it didn't lock once spun over nicely

As you may be well aware of,this Engine has Cam Followers. Stuck and or sticking valve,sticking Cam followers,dislodged Governor fly weights are high on the list of possible causes of engine locking up.

I believe, if any of the above are happening,and if and when the engine is rotated in reverse from normal operating rotation the engine frees up,I personally would inspect the Cam Followers,and the Governor Fly weights. If it was my $$$$$'s, I would verify the above is not the cause of the engine locking up.

When my TEA 20 acted up I placed a socket on the head of the "CAP SCREW" that holds the pulley to the CRANKSHAFT . I then turned the crankshaft Clockwise until the rotor (remove distributor cap and view rotor)started to move. I then turned the crankshaft counter clockwise until the rotor started to move and found that the TIMING chain, and both the CAM sprocket and Crank sprocket had to be replaced. Once I opened up the front cover the GOVERNOR assembly also had to be replaced.

Info I compiled when REPLACING Crank sprocket ,Cam sprocket and Timing Chain.
(1) 85 MM Bore Engine:

(2) Front Lip Oil Seal "National /Federal Mogul Lip Seal" # 472164V A SMALL amount of BLUE Silicone was placed around the inside bore of the front timing chain cover before Lip seal was installed:

(3) I installed a repair SLEEVE on the front drive Pulley, make "DURA SLEEVE" # 99175. The sealing area were the LIP SEAL makes contact was slightly grooved. Dura Sleeve specs. 1.745">1.753" Diam. # 68 Rockwell Hardness:

(4) On installation the Governor plunger shall be reseeded tight against the Flyweights and no weights shall be loose or hanging down:

(5) A small amount (only enough to make the surface shiny) of engine oil was added to the shaft of the governor PLUNGER as well as the timing chain:

(6)There are NO timing MARKS on the NEW Sprockets. You may wish to line the timing marks up (facing each other) before you remove the sprockets:

(7)Place the old sprocket (CAM SPROCKET) on top of the new sprockets and accurately scribe the new sprockets as to the timing marks. There are FOUR holes in the hub of the CAM SPROCKET. Keep turning the old sprocket until the four holes and all teeth line up. These holes are slightly off set. I used several SHOULDERED cap screws to ensure I had the new and old sprockets properly aligned. You may have to flip the old sprocket over...see right up:

(8) It's good practice to measure the thickness of the hub of the old crankshaft sprocket and the new crankshaft sprocket as the teeth on the two sprockets should align for both proper operation and longevity.(there were shims between the old Crankshaft sprocket and the shoulder portion of the crankshaft):

"IF" the timing chain on your machine is as bad as this pic....Time for a new Chain as well as both sprockets...
