Oh man, this brings back memories. From 1976 to 78, I worked for a paving company. I used a machine just like the one you have. And yes, it was a beast to run on uneven ground.
I’ve always heated the last inch or so red hot and then bend the hook, then requench in water to restore the springiness. It’s worked well for many years with my outboard, especially when we were in isolated areas. Usually that’s where the spring decided to bust.
A trick from the bicycle world for hand grips, you can sometimes use an air compressor to get just enough air in between the bar and the handgrip to get it on or off. It made my day to see this video to watch today in my feed. :)
I slip one or two pieces of welding wire, (even coathanger would work), into the hand grip, and then sprinkle talcum powder in between the wires. the hand grips will turn right off.
@@josephkrug8579 That is true, but you only need a light spray. I have a plastic bottle with a fine tip, because I use the powder for other jobs, such as accelerating the drying of superglue. I don't know the next time I will have to remove handgrips, but I will remember the compressor trick and give it a try. I am not afraid of new tricks.
You never cease to challenge my brain! Going the extra mile and changing the parts to fit your need. And do justice to the machine. Got a kick out of this one!
I spent many years working for a plant hire company and did many repairs on the Robin engines . Replacing the recoil spring was the least liked job , had many springs try to escape as yours did . It felt like winning an Oscar when it went together ! !
Shooting a little air under that rubber handlebar grip will make it come right off. Also hairspray will make them go on easily and will sort of glue them on when dry. Learned that from putting on the left grip on a motorcycle handlebar.
I worked in bicycle shops and those both are standard practice. I love the smell of Aquanet in the morning. If you're good you can shoot the opposite grip off with the air hose and hit your buddy working at the next stand over.
When I worked in a bike shop we would shoot a toot of compressed air under the edge of the grip to remove it and use hair spray to lubricate the grip for installation and then fix them in place. Love the video. Keep up the great work!
Great to see you posting again, you’ve been missed. Can’t believe someone would throw that out, still gold for you and us to. As for the length of the video, I thought it was ideal and enjoyed it all. All the best for 2023
According to the innerwebs, the EY20 is 5hp. There are all kinds of manuals available also. That appears to be a simple hydrostatic transmission. There is no high pressure on the outside, the bottom line is suction and the top line is return. Great find! Great to see another video, too long since the last one.
To filter out debris in the fuel I use a cheap plastic funnel (the orange ones) from Harbor Freight with a coffee filter in it. The filters are cheap and work great whether you’re filtering straight gas or a 2 stroke mix. The filter doesn’t breakdown from the fuel and the white filter allows you to see even the smallest particles. Enjoyed watching you save this roller from the scrap heap.
If you stamp the gasket surface on an ink pad then stamp it on the gasket you should get a good representation of the gasket without hammering on the soft metal & risk damaging it.
I rescued a little 5hp robin engine with a hole in the crank case I made a plate for the hole and ran it with a bent rod on my lawn mower for about 4 years. Economical to run and still running when I sold the mower. Bullet proof.
Great score, no major parts broken so not too hard to repair. Can see the love in the dogs eyes when you were petting her ❤❤❤, all the best from the UK.
Just a little tip for feeding the pull cord back, cut a notch the same size as the cord in the plastic pulley. This will allow you to wind the cord while the handle is fitted. Honda GX engines have these as standard, but the robin engines don’t.
Yeah it 5hp. But for us eu guys kw is comparable. So for example if i have seen what kind of power 3.7 kw electric motor makes i know how much power 3.7kw petrol engine would be, because its the same.
On spring stock, if you sand off the blue on the last half inch or whatever you need to bare steel and gently heat until the temper color goes back to blue and while still hot, you can bend the end to whatever shape you need without breaking the end off and without overly softening the spring..
Great Job Matt. I love these kind of vids. Find some free or cheap, get it running, then showing it actually working. Keep up the great work. Look forward to the next one.
Nice to see it resurrected, great work .Tip roller easier to use with handle lowerd , and when before you stop in any direction turn off vibration as you will have ridges especially when rolling asphalt, thanks for sharing 👍
Great Dave on what seems to be a perfectly good little machine. The Robin engines were made by Fuji Heavy Indistries, now known as Subaru, which is why Subaru would have parts for it. They later sold the small engine business to Yamaha so parts might also be available from Yamaha dealers. IR is now owned by Doosan which now calls itself Develon. It's a game just keeping up with who makes what.
Oh man, I fell for it. Glad it was a joke tho! I enjoy watching your videos and recently plowed thru your shed building tutorials. I enjoyed them so much I literally just purchased a framing nailer !! I feel empowered now. Bring in the shed!!
A hydraulic shop should have that orange hose in stock, or a good replacement for it. One near me also makes brake and power steering hoses with my old parts.
I am a new viewer; in the past I have failed to overcome the broken recoil spring failure ; the lawn mowerwas put at the curb and disappeared;I placed a sign motor runs good!Thanks for your hard work and strong video content
That was fun to watch. A friend loaned me a plate compactor that "ran fine", NOT. Same tank & engine, but older, with a paint job that obscured most ID on the unit. The carb cleaning brought back fond memories. It's a great feeling to bring life back to what might appear to be a lost cause. After revival, it worked so well I had to add & spread two more tons of gravel just to get the level back. Thanks, good work 😎👍
Great that you got the old beast running again. Now I would try and sell it to a landscaper or a paving company and just find yourself a small to medium plate compactor. One of those would be a lot easier to maneuver on uneven surfaces
Robin motors were the Rolls Royce of lawn mower and garden/small industrial equipment. Were very expensive compared to other motors but lasted a life time. Regards from South Africa
great trick to remove those stubborn rubber handles: punch a hole at the end, insert a compressed air nozzle and they fly right off! :) learned that in the bicycle shop i worked in as a teenager.
Have you ever used sta bil fuel stabilizer in your fuels by chance? It's something you might want to look into if you haven't before. Major game changer for ya.
That my friend is a job for a plate compactor. As u said, that’s primarily for narrow strip asphalt. You notice the water tank. That stops the asphalt from sticking to the drum. Good find, good video. Thanks.
I'm not too sure about that particular IR compactor, but I had a similar one and the small roller in the rear was adjustable... I'm pretty sure you would find it easier to control if you could swing that back roller up a bit...
For hand grip removal, lift the grip a tiny bit and spray Windex in the crack between the bar and the grip. Capillary action will pull in the Windex and the grip will slide off.
great to see the use of an industrial stethoscope. Tip: hold it to the bone behind your ear. I have a BAHA (bone anchored hearing aid) these days and it clips into a bolt that's screwed into my temporal bone (the bone behind your ear) and it is far more effective as it goes straight to the hearing nerve via bone conduction. I used to do the same as you did in the video when I was working on machinery in the holds of ships and wish I had known this back in the day.
As a child I remember my stepfather being impaled by a forklifter fork he was shifting a pallet by hand turned around and was impaled by the fork then pinned against the pallet stack luckily he wasn't alone in the warehouse during the night shift his coworker backed the lifter off him then he picked himself up off the floor and drove himself to the hospital too get stiched up . If you only need one fork to lift take one off or move the forks together never have a gap you can fit in and never enter a gap between forks never have your back to a forklifter or any other piece of operating equipment practice proper equipment operation safety it only takes a second of negligence for injury or death to happen.
Great Job !! As for the gas tank... You might be able to get some of major ding's fixed, by using compressed air ! If you can find a metal fill cap and close up the vent hole. You can use the the threaded fuel line port for the compressed air. I've used this method for restoring vintage motorcycle tanks ! PS: You might be able to use a motorcycle throttle, brake or clutch cable, for your throttle cable problem too.
Nice find. Packers are so darned useful. The extra tube on the top of the carb, is probably the float bowl vent. I'm guessing it needs a hose to run into the back of the air cleaner. Killing the engine with the fuel shutoff valve, is definitely the best way to shut off an engine...especially if it is likely to sit for a while.
good to see you back, heat the end of the recoil spring, this changes it back to mild steal and bends, but u probably know that any way, looking forward to seeing more
I wouldn't have imagined passing nearly 2 hours watching a guy fixing a roller😂 ... and with your screwdriver stethoscope, you reminded me the diesel engineer in the excellent movie Das Boot who was listening his motors thru a long motor valve
Great score and great job restoring it. Not really meant for rolling aggregate this large but would definitely work better on smaller stuff all the way down to crusher dust. You mentioned something about the rear roller being bent. Perhaps you could make another on your metal lathe and even make a new "killer" CAP for the water tank
I worked on bikes. You can remove the grips with compressed air, by using the pistol, and we used hairspray to slide them back on and fasten them again. When it dries they are solid.
Quick tip for removing grips.... spot off oil on the end of a flat screwdriver, tuck it underneath the grip edge and as you skid the screwdriver in rotate it around. Easy job.
This is very useful, instead of squirting petrol in the spark plug hole: Nulon "Start Ya Bastard" Instant Engine Starter (SYB) promotes easy starting of all diesel and petrol engines (both two-stroke and four-stroke). Preserve battery condition and it is totally harmless to engines. One short spray of Nulon is all that is necessary to start the most stubborn of engines.
the long screw driver ear thing! YES!!! Would that I still could. I am older but I know lad... I know... I am deaf in my right ear. 30 year ago I could do as you did...
Putting a clear hose on your funnel helps a lots , and take a small screwdriver pry the end up and spray water around the grips will help remove them .
For dragging that out from a dumpster, I would say you done very well. As you always do. Nice to have you back by the way.
Oh man, this brings back memories. From 1976 to 78, I worked for a paving company. I used a machine just like the one you have. And yes, it was a beast to run on uneven ground.
I read this comment while he was working on it in the video. Then later saw him trying to use it and couldn't stop thinking about this comment hahaha
Who would have thought of really get into a video of an old hand roller salvage. I love it and love the fact you saved it from the scrapper.
I’ve always heated the last inch or so red hot and then bend the hook, then requench in water to restore the springiness. It’s worked well for many years with my outboard, especially when we were in isolated areas. Usually that’s where the spring decided to bust.
Job well done. You rescued it from the inevitable Metal cruncher! Glad to see you back with us, how about us seeing your dogs miss them also!
It's about time! Where have you been young man!!?? I've missed watching my favorite channel! It's good to see you back.
A trick from the bicycle world for hand grips, you can sometimes use an air compressor to get just enough air in between the bar and the handgrip to get it on or off. It made my day to see this video to watch today in my feed. :)
A few drops of lamp oil inside the handles might do the same thing. They slide on easy and as the oil evaporates, the grips are on solid.
I slip one or two pieces of welding wire, (even coathanger would work), into the hand grip, and then sprinkle talcum powder in between the wires. the hand grips will turn right off.
@@jjock3239 That is good to know, but if you have it available, compressed air may be less cleanup. :)

And use hairspray to assemble them. Slippery at first and then ' sticky' , so they won't come off.

Glad to see you back at it. We need an update on all the other machines you are working on next projects! Thanks!
It was good to see a new video from you. I have been missing your show. I prefer your rescue subjects.
Good job! I know the roller slipping off of the rock was a pain but it was quite entertaining to watch lol

I like the cheap white filters best ... won't use bleached paper for coffee, blech!
If you stamp the gasket surface on an ink pad then stamp it on the gasket you should get a good representation of the gasket without hammering on the soft metal & risk damaging it.
Genius! Will remember this tip.
I'll have to remember that. That is a great tip.
Why would he need to do that? He has superhuman powers. Did you see how fast he was hammering? 😂

Just a little tip for feeding the pull cord back, cut a notch the same size as the cord in the plastic pulley. This will allow you to wind the cord while the handle is fitted. Honda GX engines have these as standard, but the robin engines don’t.
The old rule of thumb when I was in the Navy was, 3kW = 4hp, so 3.7 kW @ 4000 rpm would be about 5 hp.
3.7kw converts to 4.959hp
3.7 kW x 1.36 = 5.032 HP
1Hp=746W👍
Yeah it 5hp. But for us eu guys kw is comparable. So for example if i have seen what kind of power 3.7 kw electric motor makes i know how much power 3.7kw petrol engine would be, because its the same.
I think 5,5 chuck mc Atee
People that have the patience to deal with those pull rope springs have my respect !!
For a scrap roller you got a great machine Matt that was so great loved it thank you Matt for your time and sharing can't wait for next one.

THOSE PEOPLE WORKING on that machine were obviously very Knowledgeable on them it was quite complex and they did a wonderful job on it worth watching.
Maybe a cap of stove pipe might be temporary solution for the water tank. Great save of nice little piece of equipment great work as always.
Nice to see it resurrected, great work .Tip roller easier to use with handle lowerd , and when before you stop in any direction turn off vibration as you will have ridges especially when rolling asphalt, thanks for sharing 👍
It’s great to see you’re back!
Proud to see you us the screwdriver "stethoscope". I'm 76 YO and my dad taught me that when I was about 8 or 9 . It's nice to see common sense used!
HI SCOUT! Tell your dad he did a GREAT job on saving that roller!

Last I remember 100 Hp = 75 Kw Looks like 3.7 kw at 4000 RPM 3.7/75 x 100 = 4.9 HP (Approx)
Oh man, I fell for it. Glad it was a joke tho! I enjoy watching your videos and recently plowed thru your shed building tutorials. I enjoyed them so much I literally just purchased a framing nailer !! I feel empowered now. Bring in the shed!!
Glad you are back and nice score with that little roller .
Small carbs like that are a GREAT reason to get an Ultrasonic Cleaner - they work FANTASTIC.
That big tank in the front of the machine is for Kerosine. Kerosine lubricants the roller so it doesn’t stick to the asphalt
Skirts are great love the look, and what a savings making your own lowering blocks keep up the good work!
A hydraulic shop should have that orange hose in stock, or a good replacement for it. One near me also makes brake and power steering hoses with my old parts.

Nice long vid, woooooo.
we have all missed your vids glad to see you again!
Cool you were able to save that! It seems like a wicked pain to operate lol I’ve seen a few for sale in past I love my 4045 reversible plate!
I literally know nothing about this thing. Then tells us almost everything about it. 😂 Love your knowledge and skills.
Awesome save. I would suggest you put the control arm at a lower level. I think you will find you have better control.
We always ran them waist high

Man I'm so imperssed that recoil would have blown up in my hands as they have so many times in the past you are awesome
Nice to see another video!! I think I-R imported this model and I think its "roots" are now in a DOOSON SX-170 or 175. Could be a source for parts.

You couldn't find a pig that would head for the mud any faster than that roller.
