Default Ruston Engine Acquisition

We've been looking at this engine for a couple of years while another antique equipment museum decided its disposition.

They called us a month or so ago and told us we could have it, mostly because we have the space (or will have) to display it and willing hands to restore it.

It has some issues - a crack in the head and the belt pulley is broken and parts of the spokes are missing. We are also going to need to separate the clutch drive and the flywheel from the crankshaft in order to clean up the crankshaft and check for straightness.

The flywheel is 6 feet diameter and probably a foot wide, weighing i'm told 7000 lbs.

More pictures to follow.

Is that an HR6 series engine? Likely would have an EX on the nameplate too . Rob

Hey all,

here are a couple more photos of us loading and unloading the engine. I have a video uploading that will be done shortly.

The head has some cracks between the cylinder head stud holes and water jacket. From what i've seen, they don't look too bad and shouldn't be too hard to seal up.

the cylinder/frame will be temporarily mounted on a cart so i can wheel it into my personal shop and pressure wash it, check out the piston, rings, bore, governor, etc. The engine has some nice pinstriping on it which i will photograph and re create when i paint the engine. I would have liked to keep the original patina and paint, but i think too much of it is gone to be worth it.

That engine has a removable sleeve which has an Oring at the back. Might leak Might not. You may want to pull the sleeve and change it.What size is it? HR6 HR7 ?Did you get the handcrank? I have an HR6 electric lighting and a 25 KW generator. Built in 1935. Rob

We are thinking of putting this engine in our current Engine Shed, along with the Atlas and the Fairbanks diesel engines. We have room for it, but will need to cut the floor and excavate to pour a base for the engine and flywheel support to bear on.

Now to figure out the correct dimensions to accomplish that.


We believe the engine is a 7XHR, 40HP at 300RPM.

If anyone is in the area, stop in and visit with us At the Zagray Farm Museum in Colchester, CT. PM on of us to co-ordinate.

Nice engine, I like the unloading (or was it loading) with the dragline!

Here is the first video of the Ruston! if i have the time, the base will go on a cart this weekend or next and come to my shop.

https://youtu.be/uUFsOeJ1wE0

Rob, thanks for the info on the sleeve o-ring. Do you know if it's something i could replace with a McMaster o-ring or similar, or is it special? And as far as a hand crank goes, i think this engine is a bit large to have one of those! It will be cranked over on air.

Just grab a young friend and have at 'er. I start my Class 4 Ruston by hand crank
I was told of a Class 3 17hp here in Ontario that starts on 1/2 compression with a lit wick by rolling the flywheel over the top by hand, no crank

Mike emailed me these pictures.

Art brought the Ruston head up to the shop today. Took it from his truck straight into the hot tank for its first wash. Took a few pictures for the records and noticed a few stamped number in the head. Maybe we can narrow down a year this was built, I think Conner was correct about the model.
Conner I'll grab those extra parts next time I'm down.

The heads going Monday morning to the sandblasters. Once it's back, I'll start figuring out exactly what it needs. Obviously the large crack down one of the head bolt holes needs to be welded and see what else is wrong with it. I'll also surface it when it's all done. One of the ORing spots might need attention.

Great progress already on this engine everyone.

Is water jacket behind that crack or just the bolt hole?
If it's not a water leak, and not harmful for any other reason, may not bother or risk welding it?

My 6 HR has a hank crank. I think it's a bit insane trying to start something with a 75"dia. by 1' wide Fw weighing 2 tons with a handcrank. Never the less the manual gives instructions how to start it with a hand crank. The book also tells you that you can start the next size up engine which is what you have with a hand crank.That's even more whacked out. The larger ones are air start only. My 6hr also has air start.

You should be able to get O ring stock from McMaster in either sq or round. Cut it to length and glue it together with Krazy Glue.

We tried to take the clutch off of the crank this weekend in preparation for removing the flywheel, so we can have the crank polished and checked for straightness. Can anyone help with how to remove it? many parts are stuck, and in addition we're not sure how it's removed in the first place. See the attached photos.

first photo is of entire clutch (pulley rim is smashed off)
second photo is of a hole where we removed a setscrew and locknut out of the pressure plate(?)
third photo is the adjusting ring lock pin pulled out, and left of that a hole that we removed a 3" long pin from. there were two of these pins, 180 degrees from each other. there was nothing to retain them.
fourth photo is of the back side of the clutch assembly.

Looks like there is a sleeve over the crankshaft. Probably have to make a puller, and certainly going to need a rosebud or two for enough heat to expand the sleeve.

the head returned from sandblasting. a total of 5 cracks, one of them reportedly a challenge. It's out at an expert cast welder now.

we've identified a few missing parts that we hope will be located in a couple of weeks when CAMA has their Fall Show and we have guys up there searching.

The dome cover for the valve and the rest of the clutch mechanism come to mind.

The head was repaired a month or so ago. A total of 23 inches of cracks were repaired!

I jackhammered a bunch of original grouting out from underneath the engine to allow it to sit on a steel wheeled cart that we had an old air compressor on. Then it was brought to my shop and waited patiently until i was able to bring it inside as a winter project.

I started with the mechanical lubricator. It is fully disassembled and seems to be in good condition, but the pump checks are not steel balls, but rather rubber poppets. the rubber is degraded, so i will try removing and replacing with steel balls for the pump check valves. (see first pic)

The governor was next. I managed to take a few things apart, but I had some issues going further. The entire governor/injection pump unit needs to be disassembled, but i believe the sideshaft needs to be rotated to remove the nuts holding the camshaft stub end to the sideshaft (someone please chime in if they have any input!). Then it seems that the bevel gear can be removed, and then the sideshaft. However, the sideshaft is frozen and will not rotate. I've been oiling it and giving it heat, hopefully it just needs some more time.

In the mean time, I can finish the lubricator and tackle the removal of piston and sleeve.

Here is the video I made and uploaded on the Farm's YouTube channel about the oiler:

https://www.youtube.com/watch?v=8h4hfJ6nRCA

I also ripped off the rubber check poppets from the springs and replaced them with steel balls and the oiler works great! I will now disassemble, clean, and paint the oiler and it will be ready to go.
