Gasoline in the oil according to this website!

Here is another good explanation:

I personally can attest to the fact that my oil was loaded with gasoline due to the carbs leaking while sitting and hydrolocking the engine. I just wasn't smart enough to realize that the hydrolocking (even minor during start up) was a result of gas leaking. (And should have stopped running the engine until the problem was fixed.) :cheeky:

I have since learned that when you hear the engine crank slow and then "knock" at least once on start-up, there is gas leaking into the engine. I think my bearings (shown above) prove what type of damage gasoline washed out bearings can look like!

Hydroloc......I have found mine would turn over with the starter just a very small amount and stop the starter.
Releasing the starter button then hit it again it would crank over.

Save your engine, turn the gas off when parked.

Pulled the Mains Loose RTear Black Middle Red/Brown Front Green/ connecting rods 1/3 red/brown 2/4 Green hope this helps need new bearings

You're going to need these numbers and letters:

The black and brown coded main bearings, as well as the blue and black coded rod bearings, are still available at hondapartshouse.com, and maybe others have different ones. We'll get you figured out.

the code science ... opcorn:

 

[Steve83]

Yup, a strange way to build an engine - I've never seen anything like it. The Goldwing is the only bike engine I've ever rebuilt, so it may be standard procedure, but on car engines, I measure crank journals for comparison to factory specs, machine as needed, and install appropriate undersize bearings. This color code stuff is strange, but it seems to work. My '83 has no bearing noise at all after the rebuild. I got lucky and had "II" codes on the case, "2" and "B" codes on the crank, and "2" codes on the rods, so all my bearings are brown codes, which are available.

The main concern I had was the fact that the right side rod bearings (#1 & #3) have no oil holes, and these were not available. I'm not sure why the factory built the 1000's and 1100's this way, then had them all drilled on the 1200's - probably excessine oil burning on the right side of the early engines. Anyway, I installed drilled bearings on my 1100, along with new rings, and so far, no blue smoke. Who knows...

 

[joedrum]

is there any numbers to this quack tech so one can figure with common sense

 

[Steve83]

I wish there was an easier way. Makes no sense to me why they did it this way. Then they say that the crankshaft cannot be machined because of the specially-treated surfaces of the journals. I did tear down an '82 with a spun bearing, and the crank was fine. Go figure...

 

[CRAFTMAN6001]

Here is the breakdown of the bearings. Mains Rods. Block stock number an code. (VIN) 01/77 small stamp 1978 LARGE STAMP.

 

[dan filipi]

Gee, those bearings look real good.
Why are you replacing them?

 

[Steve83]

The bearings do look good, just a little pitting, but not on the thrust surface. I would not hesitate to reuse them. I'm curious though, #2 and #4 rod bearings should have oil holes in them, none of these do. How do the main bearings look? The only sign of wear I've seen so far is the primary chain.

 

[CRAFTMAN6001]

The main Bearings look about the same. Holes in the crankshaft There is one Tincy spot of Brass close up by the tang area. Other than that all is same. I washed the half's out with a wand. Diesel fuel. compressor @ 45 psi. Then straight air. Head Gasket set kit. Need new Orings for the front case and that front gasket plus the water tube gaskets. I haven't split the tubes from there Orings. New clutch's thermostat . Fan switch, Oil filter Bolt it back together I suppose..

want new ones if I could get all of them. Peace of mind mostly. A sound engine.

 

[CRAFTMAN6001]

I would like to run down a complete set Steve, Do you think they can be had?

 

[Steve83]

You should be able to find the black (13322-371-003) and brown (13323-371-003) mains. Green mains (13324-371-003) might be a challenge to find.

The rods are: Green #2 & #4 (13218-371-003), and brown #1 & #3 (13223-371-003), and might all be a challenge to find.

The numbers in parenthesis are the part numbers. Try googling them with the word "honda" and you'll get lots of suppliers. The search is on! Ebay might have some. Be careful with the ones you have, they have some life left in them.

Try to find a primary chain - I have a feeling that's what caused most of your noise.

 

[CRAFTMAN6001]

Chain. Hmm. I'll look around for sure. Thanks again, For all the information on this. :rocks: :thanks:

 

[joedrum]

well i dont really agree ... now thats good pics to look at ...its obvious to me 2 and 4 have out of round wear marks ...there been trauma here here ... it looks to be without a lot of mileage on it but trauma all the same ....hmmm suppose to have oil holes here......

it hard to say but i will just say it ....this show signs of being wrench out of shape ...it the only way possible to get wear marks like that .... the 2 and 4 rods..... and rod caps especially it looks have been stretch ... all the evidence is quite visible ... im sure the rods and caps need to be resized or its just going to get worst.....

classic sign of the motor on one side doing all the work and the other side lagging ... seems a lot of oldwings get hammered like this from cappy carbs and ignition .....this made this motor out of balance ... from outside cause mainly carbs or ignition creating unbalance load ....

in few words as possible the rod caps are stretched and rods to some extent i am sure this causes knock ... in my opinion this is where the work needs to be done ...back in the day resizing rods and stuff was just part of it

You are right Joe!! There should be oil holes in #2 and #4! :shock:

Is it possible this case has been split in the past and someone else already installed bearings? It is possible Honda did not install the correct bearings, but very unlikely.

BTW, this one is on Ebay right now...

[Steve83]

I did mention the oil holes earlier, which seemed strange - on such a low-mileage engine - could it have been apart before and the wrong bearings installed? Why would it have been split?

Do all 4 crankshaft throws have an "A" code on them? They should for these bearings to be correct.

Do you have an inside micrometer, or caliper to measure the rod bores? It's the only way to know if they're out-of-round.

This one is interesting...
