Hello , congratulations for your hymac vidéos. I had one 370c that i ramdomly bought to build my house. I did not know that brand but it was the only Backhoe i could afford. I spent many hours on it as well as beneath it. Had to rebuild the ford engine , injection pump, alomost all the pistons seals and hoses, electricity tyres, lights and so on. Finally i sold it after 10 years and 4000 h of work. And i bought as a backhoe replacement. Another 370c 😅😅 but that have been totally rebuilt by on old passionate mechanic. These backhoes are really toughly built and the ford 3 cylinders allows to work long hours without drinking too much. Each time i am seen driving this 48 years old english machine i arise people curiosity. Here in the south of France only Case and Jcb rule. What a pity this brand disappeared, a 4wd 570c would have been a best seller.( Fai like) Regards from France.
Thank you for your comments, it made us laugh when you say you spent many hours beneath it🤣they are very good machines and the operating position for the backhoe is very comfortable for its build year, we rebuilt the 3 cylinder Ford after it was parked up for 6 years, unfortunately we had not started the channel then and did not video the rebuild but it was the start of the “maybe people will watch what we do!” It is a shame that the once popular Hymac brand is no more but with people like yourself memories live on, stay tuned to the channel we have some good content coming up, greetings from Le Pays de Galles🏴
Thanks, we have a lot in store and hope to get on with some soon, it is a very rare machine and not many survive in a working condition, lots of power with the short dipper configuration and the engine sounded sweet with the turbo purring away👍
Glad the hydraulic tank wasn't as bad as it originally looked (did save the hydraulic tank off the Laverda 3900 combine in case you did need it) and the repair came out really good.
Thanks, I’ve got to be honest I’d never heard of a Wabco C Pull, don’t think they were used in the UK but I could be wrong, I just looked one up on RU-vid, mean sounding with the Detroit Diesel humming away and elevator chains loading the box,it was usually a Euclid scraper box with D8’s or D1O’s pushing behind even though the scrapers had two engines they still got stuck
Thanks for the videos on the KH41. I have the identical machine that has a ROPS vs a cab. My machine is in use on a regular basis. I purchased it used in 2006 with 2600 hours on the clock and it now has.just about 4700 hours. It appears your engine is worth saving even for another application. There is so much rust and determination on the machine it may be beyond restoration. I live in Nova Scotia , Canada and cold starts have never been an issue but cold starts need glow plugs year round. I can still get parts from Kubota including final drive. New tracks easy to get so I’ll keep the machine as long as it goes to work, it will probably outlive me and I am 83.
Thanks Des! We are giving it every chance to be saved, we have revisited it and more videos to come so stay tuned👍 this weekend we were repairing the hydraulic tank off it, we’ll post a video of it so you can see the work that went into it I bet the Nova Scotia climate tests the battery and glow plugs to the limit? Take care👍
@@RustNRestoration A good battery has never failed a strat even in the coldest days but with glow plugs - a great engine IMHO. I have a Kubota RTV 900 with a slightly larger 3 cylinder engine that also also gives excellent service but it is younger in hours. I have 2 Yanmars in my John Deere tractors and they also give reliable cold weather service but are the youngest engines I have. Given good fuel, a charged battery and air and good mechanical condition, it should/will start. You made a good call on the rings and the runaway was exciting. I look forward to your future videos.
What a great video. Thanks for putting your time into it and working your own 370C. Looking at your 370C a few parts there we used to supply to HY-MAC. The rear bucket linkage, the stabilizer feet and the stiffener gussets welded into the rear wheels. On the 580C we drilled out the mounting holes on the counterweight. As it was cast of scrap metal, not an easy job. Pilot holes and patience to get it done. I didn’t realize until this video that the POWERFAB is a 125W, earlier than the 125WT. It had its own trailer. It would be interesting to know the machine number. The 125WT as the logo says has a trailer built in to the design. My sisters grandson was at the show, just 4 years old looking at all the machines especially the POWERFAB , as his great grandfather and his 3 brothers owned the company. 👍🏴🇺🇸
Wow thanks Paul for the information! Great to know you had a part in the HYMAC story along the way, the Powerfab 125 WT is a great example, don’t think we’ve got any footage but a Powerfab 125WTD arrived in the guise of a Lifton 125, basically a Powerfab under a different manufacturer and yellowish in colour, hope your sisters grandson enjoyed the weekend, fantastic connection and a history to be proud of, it was a very well attended show and we raised a healthy amount for local charities over the course of the weekend, hopefully see you next year👍
Thanks Sali, hope you had a fab time, something for everyone, glad you could get to have a go on the 370c and experience back in time what it would have been like digging back in the day👍see you soon
The first thing you do on a diesel engine that turns but hasn't been started for awhile is open the oil pan plug to check for water in the crankcase. Then you check and free up the injector rack to prevent a runaway engine if it does start. 3rd you pull the valve cover, push down hard with your hand on each valve spring to see if the valves are moving. If one is stuck, spray some lubricant and hit it with a hammer until it recoils. Then work it until it's free. Next check the fuel filter, clean any gunk from it with diesel or a cleaner, fill it up before installing it. Drain the fuel tank or set up a temporary tank then flush the lines, and bleed the air to the filter. Pull the oil filter and rinse that out. Check air filter. Check all the electrical connections, wires to the starter, alternator and ignition. Hook up the battery, turn it over and bleed the injector lines until there are no more bubbles. Most people stop bleeding them as soon as they see fuel come out and tighten them back up leaving them still full of air. If it does not start right up, pull the injectors and check them for a good spray. Clean them and an engine will run if it has compression. that can be checked when the injectors are out. I enjoy watching these startup videos but the guys who don't follow a proper troubleshooting procedure waste video time cranking an engine over and over without any result and washing the cylinders with starting fluid. Be an efficient mechanic, don't bore and irritate your audience with a bunch of chatter. Mechanicing is very rewarding when done properly. If an engine is frozen with rust, tear it apart. Impatience is not in the vocabulary of a proper mechanic.
Yes a cracking show with something for everybody! Well attended on both days, sorry didn’t have more time for a chat🤦🏼was busy driving the Aveling Barford dumper, Hymac 370c , Preistman Cub and the Westwood Muscleman towable digger🤣
This is the one fitted to the Ford www.ebay.co.uk/itm/222998416877?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=mLtSYuGbSIW&sssrc=2349624&ssuid=ldnGIDhoQza&var=&widget_ver=artemis&media=COPY
Looking good. Any idea who previously owned it. Hopefully Julian Carder will be there with his STEELFAB 180. Last year there was an early POWERFAB 125WT with a Lister Petter diesel engine fitted. Watche it on Martins channel. Please take some videos if you have time. 👍🏴🇺🇸
Would be nice to see Julian’s Steelfab make an appearance, haven’t heard if Brian will be there with his Powefab 125WT, but there will be a new exhibit like a Powerfab! A rare Westwood Muscleman which was built in Plymouth by the garden mower manufacturers👍
Decompression lever was seized, never understood what and why they were fitted, I’d love to know if you could enlighten? Should it have a cable fitted?
@@RustNRestoration yes its for when conditions are in the negatives it allows engine speed to increase as compression can be lost with piston ring shrinkage batteries generally lose strength in the negativs also and struggle to swing the engine fast enough to atomizer diesel. Summer use of decompression leavers would be when a battery is low or if you have trouble bringing fuel from the injector pump to the injectors this saves not only the battery but prevents starting motor failure
You will need that compression lever full close for the cylinder to ignite, use a grips and wd40.. ether should not be used unless you have multiple bad injectors. this older model engine heavily depends on a 12 second long glow.
Brilliant thanks for taking time to explain👍 I remember decompression levers on the old dumpers and I was told not to stop them on the decompression, makes sense on what you explain, less strain on the engine and it will turn over faster, will try it when we revisit👍
@@RustNRestoration no worries lad just a side note on the lister and petters engines it didn't do the engine any harm because the valves could never interfere with the piston the only reason old boys said that was because the flywheel on them engines was the weight of 3 bingo woman and didn't stop spinning for 5 minutes so the lever would fall back down by itself when you walked away from it and reignite , if this was on a hoist or a winch with that engine back in the day that was fatal as they had a hand clutch normally engaged, unless information😅
@@RustNRestoration Hi Please you would be give me the garage handbook from the 370c i have some problems with it so it would be great when you give it too me You know about the norms from the injectors how much i must open them Best regards Joachim
@@RustNRestoration hallo Vielleicht hast du ja mal Zeit mir die Unterlagen zu schicken und die Kontaktdaten zu dem Ersatzteillieferant dann könnte ich mit dem reparieren anfangen Best regards Joachim
Hallo Ich habe mir auch einen Hymac 370c zugelegt und jetzt brauche ich reichlich Ersatzteile. Habt ihr Quellen wo ich diese bekommen kann und eventuell ein Werkstatthandbuch damit ich das Schätzchen vernünftig zum Laufen bekomme Vg Joachim
Ich freue mich, dass Sie einen weiteren 370c gespart haben. Ich habe einige Handbücher. Wenn Sie Ihre E-Mail-Adresse angeben, schicke ich sie Ihnen. Ich habe einen Teilelieferanten in Großbritannien, der einige 370c-Teile hat
sounds like you are building thunder bird 2 lol tell the old boy i told him years ago amey was the valleys designer wear and he is still proving me right note the sound goes very quiet at some points and hard to hear but great video
Yes John we are looking to purchase new microphones, we found that the mics were picking up interference when close to us so I held this one, thanks for the feedback hope your enjoying the channel👍still wearing designer ameryarni🤣🤣
I had one of these. You are right parts a massive problem. I don’t even think Renault have the correct parts book. It is a 18 tonne truck but not with single rear wheels. The Original had twin wheels with 215 R80 22.5 tyres. I suppose it’s worth the work so long as you don’t need to MOT it. Finding all the parts to get them through is so hard and expensive. So many air leaks. Not just the brakes. The chassis number is on a plate behind the front grille as well as the axle weights. Anyhoo good luck
Thanks David, She's still plated as 18t but not sure what it would be in its current configuration. We'll see what the total build weight is and decide whether or not to go back to a double rear setup at that point. Any spares left from yours?🤣🤣🤣👍
That’s a cracking 370C. These machines were underrated in their day. She sounds sweet enough. Doesn’t look as if she needs to much work to be respectable and visit shows. I worked for a company that made many parts for that 370 as well as 580s and others. The feet, bucket linkage and rear wheel strengtheners were provided for that machine. Takes me back a few years. Lots of stories how the 370s came into production but it could have been many years earlier. We used to transport the skids- engine, gearbox and drive axle in from Fords at Dagenham. As a teenager I spent many a Saturday morning in HY-MAC and later in life also. It was a great place to learn about diggers. I was very fortunate to know many people who worked there 👍🏴🇺🇸
Thanks once again Paul! I took it to Welland show a couple of years ago and there’s a video of it digging in a classic line up of Ford Autodig, case 580g! Strong machine and I learnt on the forerunner model a Whitlock 505, when Hymac went into receivership I heard that loads of 370c cabs and parts were simply sent to a local scrapyard , thanks for your support and we’ve got loads more content lined up, stay tuned👍
I think you will find that machine is probably from around 1990 or later. They started the 1200 with the Honda and Kubota engines in 87/88. They had a cracking 180C that came out in 88 also. The 125 WTD was then in its final version and was also spot on. POWERFAB were way ahead of their time in designing and manufacturing mini excavators. 🏴🇺🇸
@@RustNRestoration Yes. The 125 WTD, walking, trailing, drive could be towed on the hydrostatic axles. The drive units could be removed easily to convert it to a walking machine and it could then fit inside buildings or back yard through a standard doorway. 🏴🇺🇸
I buy in last year Hymac 370c Whitlock 1977 with Perkins 3P. Although it has a rusted floor and cab, scarred hoses plus a few minor things. The hydraulic control for this year is brilliant, leaving other designs behind. Therefore, i wants to do what I can in this condition and then I take it for a decent restoration. It is nearly 50 years old and no overhaul before, I want to keep it because it feels old decent engineering and mechanics. Great machine. I'm just wondering whether to try to improve it by retrofitting, for example, a compressor and an air seat, installing LED lights, or try to stick with the original.
Good luck and great to see another one saved! Interesting idea to install air compressor for an air seat, led lights would be a good upgrade, let us know how you get on👍
I've worked around many of those small Koboata diesels and they are super tough. Going full rack and running at valve float RPM's for hours on end doesn't even bother them. I've seen many do it due to the rack linkage or springs in the governor breaking and surviving being run like that for days just fine.
Thanks tcmtech, that’s good to know and we were wondering if it may have caused any damage, we will revisit it and try to investigate and free the rack off if it’s stuck👍
