I didnt want to screw up my build thread with my anger.
Building a 2056. Took the engine case, crank, rods, flywheel, cylinders to the local machinest. 2 months later I finally get everything back and pay the man what was agreed. The work that was performed:
jugs were bored out to 96mm
case was cleaned and check for straightness and bearings pressed in
flywheel was cleaned polished
crank was polished etc. with rods rebuilt with new bushings (custom) made by machinest and assembled with new bearings supplied by myself.
again... crank was fully lubbed and assembled ready to go in.
finally everything was balanced and returned to me.
FAST FOREWARD
I drop off the engine components to Tony @ Translog GT and ask him to assemble the longblock. I didnt want to Fudge anything up. And I have great repect for Tony and his buss.
Tony calls me today and tells me that the crank was absolutly unusable. He tells me that one or more bolts on the flywheel end were sheerd off and the end was all buggerd up. He cant believe that someone would perform the work that has already been done to this crank. He mentiond a pin also, I really dont know exactly what he is talking about until I see it first hand. He said he will try to shoot me a few pics today, either way I will be picking up my crank and calling the machine shop.
I am angry, but still not sure if I am at fault here. I took the engine apart myself, and dropped the components off myself. I told the machine shop to do the work, and I am not expierenced at engine building. This is my first build !
I just threw away hundreds of dollars and 2 months of my build
WHAT do you guys have to say>>>>>>>>>>
p.s. I am calling the machine shop now.
Sounds like a bad deal. I hope the machine shop will step up to the plate.
Ummm....bearings don't "press" in, you have to press a little bit with your thumbs on the center main and the number 2 you need to heat the gears to slip them on.
The custom rod bushings, did you modify for 22mm pins? 24mm pin (stock) bushings are available...
The crank should have never passed visual inspection if your guy is right.
still have not seen it, i will be picking it up tommorow. I did however give Tony the phone number of the machine shop. Tony didnt get a chance to call me back before he left today but.... the machinest just called me 1 min ago.
"Joe I talked to Tony and he explained to me that it looked like the flywheel had come off at some point or another. The pin was sheered off and needs to be drilled out. The surface also needs to be machined down and you will need to make up the difference with some shims. I just assumed it came off of a running motor cause thats what you said, so I never checked the other end there. If you bring it to me tommorow i will have to put it all apart again and do the work for you. I want to make it right, and Tony said that would be satisfactory."
I guess this is the best way to proceed. He is willing to make it right. I will need to talk to Tony first to get his opinion. And YES you guys will get pictures
oh yeah...
Thank you Hoteshoe and Vacca Rabite
Bummer you had to deal with the extra hassle...but it looks like the guy is standing behind his work. Looks like things will work out and you will be soon!
Having Tony call the guy was a good choice. Engine builders go to machine shops. A bad word from Tony could cost this guy lots of business from other engine builders. On a side note, if you took him some buggered up stuff and told him what to do with it you esentially got what you paid for. The fact he didn't mention the other issues with your crank is questionable.
A REAL machine shop would have chedcked EVERYTING themselves vs.relying on the customers word. The shop is resposible for the fix, and if they try and charge you any extra $$ they are b.s. in my book. A shop should NEVER go on the customers word alone. We are the "professionals" and you are not ( no offense intended ) You guys rely on us to find the issues, notify you of them and then correct them ( if approved ) this machine shop, IMHO, is neglegent in at least 2 of those situations
I agree with scotty b
I'm bummed about this. This is a shop that I have used in the past with great effect, and let Joe know about him. He did the short block stuff for my 350 and is well known known in our area as a good machinist and a stand up guy.
I am glad he is goin to make it right, but feel bad for giving the reccomendation. Just let me know if you end up needing my other 2.0 crank. It's yours for the asking.

Just dropped the crank back to the machine shop
The pics I Promissed, here it is fresh from the machine shop
Just so I understand:
"He tells me that one or more bolts on the flywheel end were sheerd off and the end was all buggerd up"
AND
"finally everything was balanced and returned to me."
So this guy works miracles if he ASSEMBLED that crank to flywheel and BALANCED IT FOR YOU without noticing the damage???
Give me a break!
Stu
Yeah, it looks bad. Stevie Wonder can see that it's hosed up. The benefit of doubt I extended for the machine shop only goes so far.
Looks like medieval tools and procedures were used to carry out that work. I wouldn't let that shop work on a Briggs and Stratton for me!
We did a round of machine work a few weeks ago and had a real bitch of a time with the cores and parts that were supplied. I was trying to open up more of our services to those doing their own work but it proved to be a PITA because someone complained about the price even after he had agreed to it up front.
"Will you please come and look at my damage with me sir?
If we look together maybe some magic will happen.
This is horri- feel this! This even feels damaged!
Do you have tools, can you fix this right now?
This is horribly- this feels so horribly damaged.
Even if I was blind I would know this is horribly damaged,
by the way it feels."

I have seen crank journals weld repaired, remachined then nitrided for not too much money ........ could not the same process be used on that end?
Why, just start again with a better one & a different machinest
Looks like it sat in the water and got rusty...then sandblasted.
rich
Joe, is there corresponding damage on the flywheel where it connects, or did you get a new flywheel?
I don't understand how this damage could have happened and the flywheel still ran true.
Zach
I used to take pics of all angles and scribe a mark in a hidden spot to be sure I got my part back. Once had a shop call me about the "hidden" mark and if I wanted buffed out... At least he examined the part well enough to find my mark...
It doesn't look like rust to me. It looks like galling, most likely from loose or missing flywheel bolts. Maybe at one point in that engines life the bolts backed out and the flywheel spun on the crank and then the bolts were just put back in. Just a theory.
Still waiting to hear back from the machine shop
Machine guy called,
basically said that he did what I asked him to do, and he would make it right but I have to wait until next week because he is swampped.
And
He goes on to say that the flywheel must be pretty messed up also.
I dont have the flywheel because its sitting in tonys shop. WTF WTF WTF
now I will call Tony tommorow and ask him to inspect the flywheel closer. On the other hand Tony has a pretty good idea of engine building, I can only assume he checked the flywheel good after seeing the condition of my crank.
Im gonna step outide
You couldn't pay me to run that crank. I would get another one and start with a fresh feeling of confidence. Nothing worse than doubting whether or not the work or part will last the life of the engine.
But Rick, the crank always lasts the life of the engine. Because when the crank goes, the engine is gone.
(Yes, I agree with the "use a different crank" people.)
--DD
If he has to replace the crank how is that going to be now considered a balanced assembly?
I'd say the crank is your responsibility to replace it, but the machinist should never have balanced it in that condition and demanded a better crank right from the start. If the crank is replaced than the whole assembly fan, crank, fly and PP will need to be rebalanced.
A proper balance is each part balanced separately and then the rotating assembly is bolted together and balanced again. The bolts/washers will be needed for this part of the job. (BTW I balance the fly and PP bolts/washers so that the order is not important.)
I'd be asking if this was done.
Machine guy called.....
The crank is ready.
I will be picking it up tommorow. Pics will also be tommorow Now that the crank has been repaired... should I have everything balanced again?
I did thank him very much for workin things out with me. It pays to be polite
Please post pics of the repaired crank.
I would love to hear how he thought the crank got buggered in the first place.
Zach
From my look at the pix it seems like mostly rust damage connected to destruction of the roll pin when disassembling. I too wonder what the fly wheel looks like. I would guess a mirror image.
If there was enough land left surfaced at three points around the crank the flywheel would sit fairly true and might balance. I wonder though if that one would at full bolt torque. I also assume that the roll pin is there for positioning, so how can you attach the flywheel for balancing without the roll pin.
I agree that something is wrong and a new crank might be the path of wisdom. However, if the crank is turned true and the fly wheel surface is also checked out the shim solution ought to work. As long as the machinist takes the trouble to get the flywheel centered and true.
Just a guess - the machine shop doesn't do a lot of work with these engines?
If Tony (Translog) says that the repair will work, then it will work. If he did not think it would work then he would say so, and refuse the work (just as he refused to continue the work when he first saw the crank). He has too much of a rep around this area to take a chance on it not working.
PICTURES
Look good to everybody?? I am ready to drive this car
Did he say how much material was removed?
As long as there's enough free play to use at least one adjustment shim it will be ok.
The only thing I can think of is that you may need to shim the ball post on your transmission to bring the pivot point of the throw out bearing out .
I would bet it does and it is not a problem to do it and not exactly need it. Just put another washer under the pivot ball, and seal the threads of the stud of the pivot ball with teflon as two washers will not keep the oil in.
Wow, that is like what I was talking about
Shimming is not usually an issue even if it is not necessary. Not shimming will suck because you need to pull the tranz back off to then shim it.
From what I understand, shimming for the 'end play' should make up for whatever material was removed and would put the flywheel in the same position as if the crank were not surfaced .........
Lesson learned: Take engine assembly to engine builder. Let HIM disassemble, evaluate, send parts to machinist, and re-assemble.
I wasted so much time and money trying to do all that myself too. Now all I will do is pull engine and tranny, seperate the two, and deliver it to engiine shop.
Machine guy told me he removed 15 thousandths (,015)
he said it was about the thickness of 3 pieces of paper
