Video rebuild
« on: March 25, 2019, 07:39:49 AM »
As I never did an apprenticeship or worked in the trade I sometimes found the Haynes manual assumes more knowledge than I possess. Julie’s rebuild has been a wonderful boost and various post have helped however when I was faced with a bench full of clean bits I was definitely nervous about getting it right. Whilst reading the manual again and pondering how to start my son asked me when I would get on with it. So explained my fears, “oh” he says, fingers tapping on his smart phone, there is a you tube video if it’s any good.

This is it. https://m.youtube.com/watch?v=vR-MiqdHi1w

Now I’m sure it’s not perfect but it really helped. So I was wondering, we have a wealth of knowledge on this forum and a lot of people who would like to know how. Would it be possible for a series of SOHC “approved “ on how to xyz be done. It would be a shame to lose the knowledge.
Keep smiling it makes the management nervous.

Interesting.

I'd be happy to put links in Aladdin's Cave (as long as Julie says these vids are OK :))

I think it's a great idea. The problem is that everyone builds engines slightly differently and uses different processes and methods and who is to say what is correct or incorrect. I think if we are going to have them in Aladins Cave, it should be pointed out that the person recommending the video has his / her name put to it saying they found it useful as a resource.

Why not let Julie video YOU doing some rebuilds then Trig, that way people can be sure it's the right way to do it!
If it's got tits or wheels, it's hassle, if it's got both, RUN!!!

Part of the reason to raise this is to find out what are the OMG don’t do that. I think one is to not put oil behind the bearing shells, but correct me if I’m wrong.

You are correct Greg. Oil under the bearing shells is definitely wrong. You knew that and I'm sure you didn't do it but, if someone watches that Vid and does as that builder did, it could end in tears. I think this is what causes me most concern, that chap obviously thinks its the thing to do but, its not, so are the rest of the people using this vid as a guide doing the same?

I looked at that some months ago and although a good guide, even with my limited knowledge, things were wrong or missing. I referred to the clutch nut removal from that vid in another post. Felt he was feeling his way, as at the beginning he said it was the first Jap motor he had worked on. However credit to him for taking the time to do it.

Sure with the skills on this site we could do much better :D

One day I'll have the time to restore it, not just talk and dream....

do you think it's wrong to put oil on the outside of the ball bearings  why not oil the balls ? also I think there was to much blue sealant on the cases looking how much squeezed out it might go inwards to

Now I’m sure I will be corrected if wrong but can see no problem with oil on ball bearings. I agree that the blue was excessive. I believe from the senior ward sister a smear (not a test) is all that is required. Standby for corrections.

Corrections.....NO, I repeat NO Hylomar of any colour anywhere near an engine. What I said use a smear of would have been Hondabond on bare machined surfaces only, ie, joining top and bottom crank cases where no gasket is used. Hylomar, or similar, can be the death of an engine when it squidges inside and goes all stringy and blocks oilways and jets. Gaskets do not need Hylomar, the gasket makes the seal.

If you use Hylomar it should be put onto the gasket in a very thin layer and allowed to dry before fitting. As per the instructions on the box. I used it on the clutch and alternator covers due to the surface being scored by a previous owner (possibly bad storage of the spare cases at some point). If used correctly it's not an issue. Problems arise when it's spread like toothpaste. As stated if it gets inside the engine it will trash it. I don't use it if all the surfaces are okay as the gasket will be good enough.

Crank case main bolts, hand tightened too much, then put a torque wrench on and the torque wrench doesn't even move, and then hand tighten again  :o


Had this engine arrive a couple of days ago, had a shed load of new parts fitted but, the oil filter spring on the outside rang bells straight away and you just know that there is trouble ahead  ???
