I already messed up the block trying to get the broken bolts out. Broken bolt removal is my nemesis.Not an overly difficult job to do.
patient and methodical will win the day
OTOH if the other block is good
1) try to drill the broken bolts out using left hand drills,
It is amazing how many times the 3rd of 4th stepped increase will free the bolt and screw it out
2) rectangular easy outs, they work so much better than the spiral ones.
I buy cheap masionary drills from the supermarket.
Regrind the carbide tip to a flat chisel point on the leading edge.
You now have a hard steel drill for a few pennies.
3) start the hole with a Dremel tool and the smallest round burr cause you can adjust it if like me the punch is always way off center.
When you have it where you want use a LATHE centre drill to start the hole.
Every ( not so ) handy man should have a set of centre drills.
It saves breaking all of those 1/16" , 3/32", 7/64" & 1/8" bits we unsuccessfully use to start holes with.

Generally speaking...? 31 Series Intek. I'll post serial numbers when I get a chance. But was wondering if it's something a novice could tackle? I have good engine with broken head bolts and can buy a used empty block on eBay for $69 shipped...
Be aware there are 2 drastically different 31 series engine blocks and they do not interchange. Will know better when you post the MODEL numbers of both. Depending on which bolt it is you might be able to use a "Thread Insert" once broken one is removed. Not in area adjacent to the push rod gallery.
I may have a good block for $20 plus shipping which would be around $15.

GEEEZZZ Walt, me thinks you could have posted the P/Ns and maybe the difference in your post, might save the "next-guy" a headache !! .. NO, .. not tryin to be a wise arse, just a curious question. Hope he buy's YOUR block if it's what he need's ..! ..:thumbsup:
Ok. So I got another blown motor today and it has a good block, its already torn down. The connecting rod let go. Only had 52 hours on it. So the number on the valve cover is 31H777-0202-E1.
The motor I'm working on is 331877-0113-B1.
I went to erepalcementparts.com and the gasket set part number is the same.

Do you think I'm good to go? I found this gasket set which is a lot cheaper but the part number doesn't cross reference but looks the same?

Yes, I was talking about a 31 to 31 swap if I got a block on ebay. I'm still considering that route if need be but I was just saying that today I got another John Deere with a blown motor but good block and was wondering if that would work in place of the 31? Don't know the differences, that's why I am asking you guys. If the 33 is a larger bore, can I just use the piston and rings from the 33?Wait a minute I thought you were asking about switching parts from one 31 series to another 31 series engine. You do realize the 33 series engine is a larger bore than the 31 series? It appears the gasket set is the same but I don't know what else without checking each part number. I know the flywheels do not interchange nor piston/rings of course. The 31 series is the newer style.

Didn't Walt say his was a 28? The connecting rod broke on the 33 and the crank is pretty messed up where the rod clamped onto the journal. Everything else seemed to be ok but I'm no expert. I was kinda hoping I could do something with what I had since I already have all the parts.How bad is the damage to the 33 ?? can you rebuild that one, instead of the 31 ?? MAYBE you should check with WALT about HIS block ! ..:confused2:

Absolutely. I take pics of everything.ONE thing FOR SURE John, MAKE DAMN sure whatever you're doing, you CHECK ALL the P/Ns on all the items and keep all parts separated as to what goes with what, you don't want any last minute surprises. Might also be a good idea to take loads of pics during disassembly, it will be a GREAT aid during REassembly. I really admire your patience AND persistance, you'll get there I'm not sure what Walt has, you need to check with him. stay close to the forum... Boo
Were you able to identify your block?Wait a minute I thought you were asking about switching parts from one 31 series to another 31 series engine.

Wonder why he doesn't reply on that ??? ..:confused2:
Just an update. Swap is almost done. Everything is going great. All I had to do was swap pistons. Waiting for the gasket set to get here so that I can put the sump on the block.
Only concern I have is with the governor, external portion. I'm sure it needs some kind of adjustment, right? How do I know if the lever that clamps onto the lever that goes through the brass tube into the block is in the right position?
Thanks, guys! The gaskets come in tomorrow according to tracking. So I will get to that part tomorrow. Looking forward to firing it up! I'll take a video. Wish me luck!
Anything else I should be weary of or is it all down hill from here?
I didn't see anything about that mentioned in the above pdf manual provided above or on the youtube videos Ive been watching. Pretty sure kit only comes with one size gasket. .015 or something like that.End play.
Very important
Too little and the crank will chew out the bottom bearing section on the sump plate, too much and the flywheel will destroy the starter gears and perhaps even the magneto coils.
So bolt everything up tight with no gaskets , then measure the end float and select the appropriate number ( or single if you are lucky ) gaskets to take up the float.
Yes that is right, the end play is adjusted by increasing or removing the sump gaskets.
Do not put any sealant on them when you have worked out what the stack size should be.
I put a light coat of high temp axel grease on both the engine & sump so the gaskets do not stick & strip cleanly.
There should be 3 or 4 of them in the kit and usually each one is a different thickness.

Just saw that. Lol. So how exactly do I measure that? Tolerances don't seem that tight, so I should be good to go. No?This Specs chart is in the Manual I sent, ..... SECTION 12, ... Pg. 174

2 Grand up to 20 grand ... that's a LOT of wiggle room !

What do they mean by step 3?About the throttle, .. IN YOUR MANUAL, .. section 1 see pages 16 & 17 adjust linkage,
Sorry John, am UN-able to locate the crankshaft end-play video yet,
What do they mean by step 3?
Ok, I was right about transmission. I overtightened that nut. So that's fixed.
That's what I figured. I put throttle all the way up and backed off where I felt the notch for the choke.NO they mean throttle full open....
That's what I figured. I put throttle all the way up and backed off where I felt the notch for the choke.
Right. That's what I did. I have the single lever. Model is LA125A according to the sticker on serial number tag. So what I said I did above is right, right?NO... when adjusting the cable IF you have a SINGLE lever for throttle AND choke...FULL fwd is the CHOKE position..
pulling back to the detent is FULL throttle .. when cold starting push the lever FULL fwd. to use choke,
when engine fires move throttle BACK past the detent to about half throttle. see OP instructions in link I THINK this is your mower model .... LA125 is the series, NOT the model, and look at the linkage when adjusting your cable.

ok. I understand now. I didn't think lever was supposed to be all the way forward, choke engaged. I'll do it tomorrow morning. Thanks. Sorry for being a pita.YOU said you moved it BACK from full fwd to the detent, WRONG !!!! lever full fwd. loosen screw, locking the cable OUTER jacket, push white piece ( if that's what YOU have, ) fwd to where the CHOKE linkage is moved FULL fwd. ( CHOKE in closed position, ) lever still in full fwd. pos., .. keep white piece in position and tighten locking screw, now throttle lever should move from CHOKE position, to detent ( WOT ) then idle position, FULL back
(or ALMOST full back) Pics of your linkage would be helpful, or maybe another member can explain it better than I can.

Do I have to adjust the governor again after?RE-post if we need to go over it........ Boo
Do I have to adjust the governor again after?
I think I'm getting it now. I did the above but with the lever all the way down and now it feels better. Too late to start it up tonight so I'll try tomorrow.
I dont see how I can do step 3 with lining up that hole by going any of this though.
I used a phone but when they upload to the site, they get rotated somehow. I don't have a camera.I can't rotate your pics for some reason, are you using a cellphone to take pics ?? use a digital camera !! on MACRO setting..??? but what I CAN see is someone REALLY screwed -up with what looks like an extra spring on the linkage/bracket assy.that DOES NOT belong there .. I will try to find some pics of the linkage in correct position. off to hunting info............
Yes, on the choke linkage, there is a spring attached to it for some reason. Yours doesn't have it nor is there one on my other block. Should I remove it?JOHN : I'm asking you, PLEEEEEZE !!! study, ..... & RE-study these pics .. NOTICE the location of EACH spring !!!
Do you see ... what I see... in your pics, compared to mine ??
It looks to ME, like someone put an EXTRA spring on the choke linkage at the "loop" end .... then conneccted it, to ..??? ( can't tell)
you might need to replace some springs I can't tell, because I cant get a decent view of YOUR pics, I use a real DIGITAL CAMERA NOT a cellphone !! .on MACRO setting ( close-up ) when I need to...

SEE NEXT POST FOR MORE......... only allowed 10 pics per post !
I took it off. Throttle lever feels perfect now! Lol. Weird. Wonder what that was all about. Here are pics.
Will do! Thank you and your wife for having patience with me! Much appreciated! Happy Easter!YESSSSSS !!! now WTF was that there for ..?? NOW try to set up your linkage as we went over earlier, re-read what I posted ....many times, if need be, remember, CHOKE linkage FULL fwd. and be sure short spring on lever in back ( which the choke link passes through is hooked like in MY pics .......... I'm outa here, ....... wifey having a schitt-fit............. manyana
All fixed and good to go! That WAS the problem! Runs as good as new! Thanks again, everyone!Was able to better view your pics this morn, yep that issue, is because you used your cellphone, no problem, I just can't manipulate your pics as I can from a REGULAR digital camera .........
WOW !! I'm still trying to figure out why the hell that contortionist sping was on there ... WEIRD schitt ! I would guess it was holding the CHOKE rod from moving fwd all the way ( and,the throttle rod maybe ..?? ) for what reason ..??? well, with that off, and if you have the short spring (on rear bracket) in place, as I explained earlier,... and the Lonnnnng delicate trottle rod spring looks just right, we should have THIS issue solved !
I wanna hear GOOD news John !! .. :thumbsup:
