Allis 301

Ok so I'm new to being on this site all tho I have been taught. Lots on hear I'm 28. Went to Beloit Ks for diesel tec in 08 & 09 learn a good bit their after collage I really started buying 190 & 180 allis tractors for $500 to $1200 even a 200 & a D-21. Anyways back on track sort of. When scrap was high me & my father scraped. Around 200 combines so I got several tiers mainly 26in in wich if anyone around ks needs any should call me by the way. So we got L,M,F& Ggleaner 301 turbo & non turbo engines I have found that if I have to get the injection pumps to free up some times not no bigy I take the top off move the metering valve really free I don't need a run away sometimes I have to pumClean hi pressure diesel into. The pump while cranking engine helps to loosen the squeezer plungers no that not their technical name. So I ALLWAS get them fired up but I bet about % of the motors I do this to Allis 301s they spin a # 1 or # 2 rod Bering I no they have sat what I would call 10 plus years if the injection pump is sticky I'm wondering if it cause the oil has turned tarry & sat on the crank glazing it. Naturally I ALLWAS check oil pressure first thing never had a problem with oil pressure. I have thought about using a gallon or so of diesel & dump it in the oil to maybe lean the gummy up but never tried it I have had tractor motors do it to not just combine motors any one no anything or have any ideas I have 2 setting 301s right now I no the sat 10 plus years so I don't feal like spinning more cranks maybe I will pull the pan this time seems they last 2 miles then blow out the blow by Quickly & hard the worst part is a few made it 5 or 6 months I bet I have went through 10 good running 301s it's a shame.

My head hurts

I'm just messin with ya. I don't know I guess your oil theory makes sense I'd definatly pull the pan on the next one. How many 301s ya got?

The old 1950's JD manuals used to say to drain the oil and fill with gasoline and run for 20 seconds or so (can't remember for sure) so clean out sludge once a year. This was before modern detergent oils.

I'm a bit Uneasy about putting gasoline in my crank case tempting else wise lol. I have probably change the oil in about two thirds the motors before I did it too

Well that's what I think I'm down to I'm thinking from now on I will pull the pan & pressure lube it through the oil pressure sending unit passage & make shure I slee oil come from EVERY berring. Just more hassle to find out if it's a good one but probable well worth it. I often have wonderd if the oils so settled that even with new oil just the seddiments are getting through but I don't no. It's ALLWAS #1& #2 rod berring if I remember correctly their last on the list to get oil

You no it's hard to say how long I ever idled them I probably do tho cause I usually put water in them fist few minets & check for leaks. I have one 301 I think I got the timing gear one tooth to advanced I have to give it a sniff of ether and I can't let it idle below probably eight or 900 RPM . It's either that or else the Venes in the transfer pump aren't picking up until centripetal force is getting them that's a different story on its own.

Yeah I get your point & I I no if u clean one of them spectrum air filters you no the ones like K&n filters with gasoline & put it on your 5.9 Cummins too quick she will run on her own without the injection pumps help haha   Overdrive & cluch put her down tho I thought I'd try & dry the filter out quick lol dumb moment you no. Good learning tho .

It's nice to no someone has used diesel as flush did u do it simply as a flush or to engines that sat years & years ?

I might try it I suppose. I'm down to just to 301s then one 201 or 200ci 4 cylinder if love to put that little fella in a bad bad engined 180 or 170allis. Some day just for giggles. Don't want to hurt it their not as easy to get still

That's a good thought to cutting open the old filter to see what's in the dirty ol beast

Ha ha yeah could I no I have. Seen sum crusty crude in pans before.

Whenever I know I'm going to do an overhaul (especially an in-frame OH) I always dump 2 gallons of diesel fuel in the existing engine oil (yes, overfull) and let it run for 5 minutes just above an idle. Now, when you work on it, it has been washed very clean by the diesel fuel/motor oil mix and overfull with the crankshaft splashing it all around. Nice to work on. I'd never use gasoline.
