Marcel Posted Sunday at 14:57 Share Posted Sunday at 14:57 My tractor Harley is acting up...unsteady idle...after I bleed the fuel line...its ok for a couple of weeks...then starts up again...there's air getting in there somehow...can't see anything external...I have no idea..maybe a bad injector ? Fuel pump..? Haven't got anything to test diesel engines...I might have to call the expert...was planning to change out the fuel filter today.. but I'll wait until I'll talk to diesel guy...im gonna services the snowblower insted...

Marcel Posted Sunday at 15:24 Author Share Posted Sunday at 15:24 Figure you guys don't see many snowblower like this in where most of you live...since im servicing it , I'll post a few pics. About the blower itself it a pronovost commercial grade , they have 3 levels of blowers...the lyns , the puma , and the commercial one wich this one is..its 72 inches wide , 30 inches high at the main intake and I think the impeler is 26 inches. Its got 356 hrs on it , they are Canadian built , no China parts on these...lol...built in Quebec...it weigh 900 lbs.. 3 Link to comment Share on other sites More sharing options...

Marcel Posted Sunday at 15:45 Author Share Posted Sunday at 15:45 Wasn't always this fortunate to own such a thing...I did freeze my arse off for many years, I remember countless nights shoveling snow at my father's house when I was boy , before snowblowers were invented...lol Before this tractor , I just had walk behind blowers...remember the first winter I moved to this place , the snow was so high I could touch the lower cable on the telephone pole...there was so much snow around the house I had to hire a payloader with a front mount blower to clear the snow around the foundation...since it was are first winter to this place...was affraid to get water in the basement when it starts melting... 2 Link to comment Share on other sites More sharing options...
Marcel Posted Sunday at 16:15 Author Share Posted Sunday at 16:15 The unit needs a minimum of 30 pto hp to run properly and thats what the tractor has when it's running properly...that's why I need to figure out why the air is getting in the fuel rail....

I would start by fitting a fuel pressure gauge to the rail and see if im loosing pressure when it's turned off...but haven't got any gauges that read that high...its a high pressure fuel pump...

Probably just a bad seal on the fuel line, something perished probably as it is rarely used. Link to comment Share on other sites More sharing options...

Well I checked every fuel line , they appear to be fine...there's a manual hand pump above the fuel filter to when changing the filter, to prime it up again with fuel....turn the inginision..pump till it's solid and you can't depress no more....I noticed when you shut it off..minute after I can pump 3 good pumps in it...wondering if the diafram could be puncture or cracked...

Catteeclan Posted Sunday at 19:04 Share Posted Sunday at 19:04 I used to use some clear fuel pipe. Connect before and after the filter as nine times out of ten that’s where the prob is. Link to comment Share on other sites More sharing options...

Could be, if the lines are all good then the next stop is the fuel put and if there is a manual primer then that’s a possibility. Link to comment Share on other sites More sharing options...

Anyway diesel were at one time easy to work on , this is a total nightmare with this polution crap gizmos on it...ill be looking eventually to try to find a diesel shop that could possibly delele everything...

It is easy to delete an EGR valve, does it use adblue? Link to comment Share on other sites More sharing options...

No adblue , its got one of those diesel particulate filter canister sitting on top of the engine , all computer control , with a bunch of sensors, it normally regenerate every 50 hrs or so , if you run at low rpm , under 2000 rpm , it will regenerate under 50 hrs...takes any wheres from 15 min to 1/2 hour for it to do its thing....all things that I would like to remove eventually....the engine bay is just totally cramped with shit, without access to anything..

All those things can be removed fairly easily, the trick is to find someone with the computer hardware to re-programmed the unit...if Im not mistaken the computer has to be physically opened up , to remove or by pass certain things....so it has to be done by someone who knows what he's doing...if im not mistaken the ecu is ultra expensive...

Sometimes you can get an emulator that you plug in that makes the computer think it is still there. Link to comment Share on other sites More sharing options...

There is a diesel shop in town , ive heard good reviews about the place , tampering with diesel emissions are illegal here but it isn't enforced, everyone who owns a diesel truck or machinery after the manufacturer warranty is over...they have everything deleted, I might stop in today and chatt with the fellow to see if he has any experience with this make and model of tractor . 2 Link to comment Share on other sites More sharing options...

And another thing...this unit is 35 hp , they have 40 and 45 hp , all using the exact everything, same displacement , same engine , the hp is controlled by the ecu and fuel pump pressure, so I could possibly get more hp if I decide to go this way...

Marcel Posted Monday at 13:41 Author Share Posted Monday at 13:41 Was chatting with the LS tractor dealer few minutes ago , he's got one of his service tech in my area (15 min away ) doing some work on another machine...he said he could check it out around noon sometime...told him yes , have him stop by...anyway there's no way to get the air out other than loosen the injector lines wich is a total pain in the arse with all that crap sitting on top of the engine...and they can preform the bleed with there special scanner tool...without having to loosen lines...

Marcel Posted Monday at 17:52 Author Share Posted Monday at 17:52 Dam polution crap again...DPF filter was 95% clogged, he's able to see it from data coming through his laptop....I guess when it gets close to regen time , some of them start acting up before the light turns on to give you a warning its close to regen time....hopefully the bill won't be to bad.. I checked about deleting the emission crap , says the have to send the ecu to Quebec to a specialty shop to have it modified.....said he did one , the ecu failed 6 months later , so the fellow had to buy a new ecu have it shipped back to Quebec and the ecu in these sell for 10,000 dallors, price went up , they were 6 g a few years ago...so definitely won't going down that road....
