Oh boy...Belarus!

Kinda got roped into helping a guy with what is supposed to be a 310 Belarus that doesn't want to start. Beyond changing the fuel filter, is anyone aware of any particularly odd characteristics I have to be aware on this thing? My understanding is they are pretty basic systems, nothing bizarre about them. I'm told it did run recently, like last fall. Thoughts?
 
When you crank it over, does any exhaust puff out?
Particularly white exhaust? If it wont start to fire off
on starting fluid, and you are sure it is getting fuel to
the injectors, I would consider the timing of the
engine might be a good place to look. A out of time
engine will puff a bit but never start.
 
Ah good RUSSIAN engineering....There is a hand operated priming pump near the injector pump?
a pull/push up and down device, at least on the 200/400 series engines. use this to fill the primary and secondary filters, subsequently to the injector pump itself. but unless you have full fuel flow to this priming pump, so check your tank and fuel lines from it. White smoke indicates a fuel problem, crack the injector connection at the pump and get fuel there and then at the injector,,, ran when parked? could be a stuck shutoff in the pump also, hence crack the injector pump output first. Hand and foot throttle i think are mechanical linkage controlled, but is there a friction clutch in the linkage that is slipping on that model...throttle moves but not at the pump? similar to a massy throttle?
hope it helps
 
The whole thing is an odd Characteristic. They arent too bad
if you can figure them about . Pretty much like a Kubota
 
One of my shirt-tail relatives has a Belarus tractor - not sure about the model. He used to borrow my Ford 2000 quite frequently then he got the Belarus. He used to tell me how much more versatile his Belarus was than my Ford 2000. I think he used the Belarus for about a month, then something happened to it so he parked it and it hasn't been moved in about 10 or 15 years. My Ford 2000 is still going strong.

I've thought about asking him if I could have the Belarus and try to get it going again, but every time that comes into my mind I give myself a dope slap, and forget about it.

the throttle is the shut off on almost all of them. make sure you throttle up a bit before trying to start.
 
Some good info posted, as for myself and others be sure to post a reason/results when you get
the time to work on it, and running, never fun to read a novel, and the last page is missing ...:)
 
Hey Bret, is that the one I've been seeing advertised up your way for the last few months? I keep thinking that if the seller came down another grand (to $1,500) I might go look at it. Pics show it to be a clean enough looking machine, but from what I hear they do have their quirks.....

Good Luck, Jim
 
Engine has a compression release. Check the filters, make sure you have a good flow, then crack the injectors. Get it spinning over good, make sure the throttles open, close the compression release, it'll start

I dunno Jim, it might be. I haven't been over to see it yet. I know guys that have Belarus and love them, nothing but praise. Then there's the other 99% of people that talk about them but don't ever seem to have actually owned one. FWIW, there are still 2 of them in Gouverneur at that place across from Smithers Goodyear. They've been sitting there for 20 years. I tried dealing with the owner of the place once and I never could get an answer one way or the other on another piece of equipment.

Thanks for the thoughts guys. From what I understand they have fuel to the injectors but t won't start. They haven't used ether because it's got glow plugs. I asked, "Are you sure the glow plugs even work?" Got a blank stare in response, so... Also supposed to be one 24v battery in this and no one has a 24v charger. That is one thing I've never dealt with. Everything 24v I've seen has been 2 12's in series.

Pull starting sounds like an option, but I'm not sure he's got anything to pull it out of the briars with!
 
My brother has a bigger one (Belarus) on loan from his FIL; they seem to have a need to spin over quite fast. If you've checked all the boxes outlined above I would suggest you hook a chain to it and lead it around a bit.

just a note : glow plugs might actually be just a glow plug in the front end of air intake, it has to
heat the whole intake air mass for all cylinders not each individual?
also besides the de-compression lever, check the power steering/ hydraulic pump, it usually has a
lever to dis-engage the pump in cases of extreme cold temp starting, shouldn't be needed at this time
of year..but?
2 12volt batteries in series, yes, suspect it has a 12/24 volt start/run system.
Its best you actually see the fuel at the injectors being a good pressured supply, not just a
dribble/bubbles, in case there is different view of fuel at injectors? all meant in a good way just to
be sure.
hope it helps
 
The 310 is 12 volt start and charge. If it's got 24 in there, somethings wrong. One good 12 volt battery is all it needs.

Huh. Thanks, when I get over I'll check on that.
