I need to relace the engine in my boat, I am considering using a 3 cylinder Perkins diesel engine. In order to match the propeller/ gearbox etc I need to know the rpm which produces the best engine torque. I also need the torque in foot pounds or metric equivalent. Usually this is shown on an engine performance graph. I have been unable to find a graph. The engine was powering a compressor. I'm sorry I don't have an engine number. Assume its the same as the engine fitted to a Massey Ferguson Tractor mid 1970's.
This is a random choice for your engine.
You would really need the model and probably the serial to get the correct specs.
The Perkins Model AD3.152 engine used in Massey Ferguson 135 tractors built between 1968 and 1975 had the following torque specs.
45 hp
1211 ft pounds of torque at 1300 RPM
Max RPM was 2000

hi there, needs to be the same number. computers need to match. tourque converters are different from 2.0/2.2 to the 2.5 engines. also shift points are different between models so needs to talk to the dash perfectly. hope this helps.

Head Bolt Torque
For your 1994 Oldsmobile Cutlass Supreme (3.4L SFI DOHC):
Foot pounds (Final torque)
Note:
Torque sequence --------- | 6 2 3 7 | | 5 1 4 8 | --------- Step 1: torque in sequence to 33 Ft/Lbs Step 2: turn an additional 90 degrees Recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) thatpermanently stretch during the initial installation.New head bolts must be used when cylinder head isreplaced or re-installed to obtain proper torque.

sounds like the seals are gone on the 4wd shaft, it takes oil pressure to keep the 4wd off, but if the seals are worn the all passes through and the 4wd will not dissingage, you will need a experianced michanic

google Massey ferguson the model number will be on the motor
Testimonial: "nice and easy answer. Great for an inept DIY mechanic like me !"

Use no sealer or treatment of any kind. To torque the head bolts you must go in a military rotation.Think of it as a spiral starting with one of the center bolts and working your way out to the ends. The torquing should be done in three stages, fist bring them down to 30 foot lbs. then going from the center again, this time in the opposing spiral, bring them down to 60 foot lbs. And lastly, bring them down to the specified tightness in your manual usually around 85-90 foot lbs. On the thrid sequence return to the original spiral direction that you started out with. Good luck, Dana
