SOHC’s 27 Ford RPU

[SOHC]

This thing is like a project within a project, I have filled the shed over the past 11 years with engines and gear boxes, and the time has come to put together a real sweet flathead using only new parts or the very best used parts, I am ditching the Ford motor for a Mercury truck engine witch is physically the same apart from bigger bore and bigger rod journals

Working on the clutch tonight, it’s all really getting expensive, the black pressure plate is rebuilt but the housing is shitty and has flogged holes and brazing so had a hunt in my junk pile and found another good one, I was going to use a 9” car pressure plate but flywheel is filled for an 11” truck, I am going to send the whole lot off to get rebuilt and see if I can get lighter springs

If all fails with the other blocks I have this one, it may clean up or need a few sleeves,   

 

[SOHC]

I have almost everything now to complete the work apart from main bearing cap studs, and a ring gear, pilot bush and clutch throw out bearing and clutch plate, I got another 5T big truck camshaft, max power and torque kick in at about 2000 RPM, I have one in the green motor, it’s an odd feeling, you can let the clutch out before touching the throttle and thing runs off the smell of an oily rag.

[SOHC]

Well everything I posted today is gone and it’s too hard to get it back so this is some shit I have done

dose anyone have a sheet metal folder? I have plans to make a new exhaust system, I got those mufflers from flyingbrick years ago, I want to have it exit behind the diff as its coming out right by my ear and the wheels swirl the fumes into the car

[SOHC]

I fitted a new ring gear myself, was $90 for the gear, the shop wanted $250+GST to do the job and supply the ring gear.

[SOHC]

Got a new clutch plate, it’s for a Mitsubishi, I may need to mechine a little bit off the centre boss, also got a new throw out bearing, it’s a Japanese one. 

[SOHC]

I just need main bearing cap studs now, I have to remove the clutch release fork and shaft from the bell housing as I remember the fork was loose on its rivit, I might make a new one out of some good steel and beat it on good. That reminds me, I must check a few things inside the bell housing like bearing retailer seal etc.

[SOHC]

I am thinking of changing the exhaust system to make it easier on me so I am not getting defend and fumed, I was thinking of making some mufflers like a flowmaster and have it exciting behind the diff, the mufflers would cover that crappy spot where I am missing the panels between the tray and the body, I think it would look sweet, I could fold up 2 channels and weld them together and weld in V shape baffling and have that metallic v8 rumble, it has a soft glass pack tone at the moment but it’s like sitting next to x2 15” sub woffers and rumbles your whole insides and earmuffs don’t do anything.

[SOHC]

The tall bearing on the left is the only one I can find to sute the spigot shaft and flywheel but it’s 2mm taller than the stock bearing next to it and in the flywheel.

[SOHC]

I will take the flywheel and shit in tomorrow, I will see if they can put lighter springs in the pressure plate,  then I will take all of the engine down to the builders and hope like fuck for no problems.

 

for some reason the military engines have little strange things all over them like this little tube in the oil pick up.

[SOHC]

Pressure plate is off being rebuilt and flywheel off being ground, I managed to find a spigot bearing that fits the flywheel and my 4 speed transmission, I don’t know much about bearings but this bearing is a groved roller bearing and not a ball race, dose anyone know if this is ok to use? 

On a flathead the spigot bearing is in the flywheel and not the crankshaft so there is little to hold in a bush, this is the only bearing I could find in the right dimensions.

[SOHC]

This is a BGC PVC valve, I don’t think it’s intended to stop a back fire, got it apart and cleaned the carbon out, I may use it but not sure yet.

[SOHC]

Not sure if I want this crap all over my engine, i have seen them hidden under the intake but it was kind of shitty 

[SOHC]

Set up a PVC system of my own style and it seems to work, I plugged the vent in the sump witch goes up into the valley but the vent on top of the motor witch goes into the crank cave is open, no moisture on the oil cap anymore and less fumes but this motor is pretty worn so still some fumes, I cannot plug it totally or it will suck air in the rear crank matrix. You cannot have everything with a flathead. 

[SOHC]

That’s about it until things start happening on the new engine.
