Hi H,

They are new ones, it amazed me that I actually knew where i had put them.

If you look at the scan you can see the difference in size between the old ones and new

That's ok, the way you said you had found the circlips as well I thought you had fitted old clips. Pictures perfectly show the reason for not reusing old clips.

I had no intention of worrying you.

I do prefer the flat hardened eyed ones as sold by Rex though myself.

Don't have much faith in bits of bent wire since losing two piston barrel assemblies that used these. It may have been a coincidence tho......escaping little end needle roller punched right through piston ring on one!

Your choice at the end of the day.

Four now on the road and at least several in bits.

I got some from Rex last year, and they were the same as the ones in Dave's pics. I know the ones you mean, Mags, I prefer those too. Here's a tip, always order two sets because you can guarantee that at least one will ping off somewhere while you try to fit it, and you can guarantee it's a weekend and you can't finish the job without the circlips.

Hi Mags,

I'm one of life's natural worriers , LOL. The new ones pictured are from Rex.

Hi Dookie,

Have you had any problems with these, while the engine is in the stand it is relativity easy for me to change them?

I could agree with you, but then we would both be wrong

The parts turned up but the mushroom push rod and also the spring that fits behind the clutch basket part numbers 90.39 and 90-98 have been put on back order, so god knows when they will turn up.

If any one has both parts please let me know

Hi Dave, I had no problem with the gudgeon pin circlips from Rex, except they seem to come alive when you get them anywhere near the piston. Just make sure you put some clean cloth over the crankcase mouth while you are fitting the circlips. If one goes ping and you can't find it, you'll be wondering if it went down the hole or not. Make sure they are properly in the grooves. Test this by rotating them once they are in. The engine that I got recently had one circlip half in and half out, and it was recently rebuilt by an experienced engineer. Obviously didn't have his glasses on that day.

Clutch stuff. I do have a spare clutch which I was kind of saving for a disaster or for the next rebuild, but I could lend you those bits until yours turn up, or until you find another supplier, so you can get on the road.

I was keeping quiet, waiting to see if anyone else would offer! wink

Thank you for the offer, But the company I ordered the spares from have a bit of a reputation with me for not delivering the back ordered spares, I have been waiting over a year for two parts to be delivered, I have now cancelled that order ,  so I'm not to confident that they will ever turn up, the reason i'm reluctant to name and shame is life as a habit of doing things like this to me . I would say that 99% of people ordering stuff from them never have a problem. so does this make me the infamous 1% motorcyclist ?

But after posting the post last night i sat down and opened a bottle and gave the whole situation a little bit more thought and it dawned on me that I have hidden away the original 1949 D1 125cc Bantam engine that i took out of the 49er when i fitted the D3 150 engine, so i do have the spares i need. I am a long way off from being able to fit the new engine any way as i can not start the spraying until the weather improves so there is no rush, I was only rebuilding the engine as i can not progress on with the rest of the build. 

The other day this turned up  so i am all prepared for the final push.

The mushroom push rod fairies have been into my shed last night, Now I tell you I have spent hours looking for this part, 20160227_145938.jpg I turned every thing out of the boxes and trays last night and it just was not there I would have sworn that I did not have this part.  , I have just been to the shed to get some thing out of there and laying on the work bench was the push rod, I swear it was not there last night. So all I need now is the Kick start ratchet spring. Maybe if I don't disturb them again tonight they will put one there for me as well.

If you get stuck let me know I have loads of second hand springs in the store you can have one for the price of postage. It is worth checking the retaining cup is not worn, it often is and the circlip does not then retain the cup in place on the shaft.

I have sent you a PM.

I didn't want to strip down the D1 engine as bits go missing in my shed

A big thank you to Howard,

If I had to swear on my life that I did have the mushroom push rod I would be dead now !!!

Dookie, I have hung garlic up in the shed so this should deter even the most determined of interfering beings from moving my stuff around , I also checked the land register records to make sure my house was not built on medieval burial grounds. 

What I did find by using the WW2 interactive map of London bombings was a bomb had been dropped right at the end of my garden.

That site belongs to Club Member Albie and must have helped literally hundreds of Bantam owners, it's also listed on our ** Please log in to view ** whistle but it's good to remind folk it's there.

Managed to get the clutch side all fitted and bolted together. New springs, clutch plates, screws,washers, ratchet spring holder, cir clip, thrust washer, locking washer and nuts and one piece timing chain fitted.

Filed the ridges on the clutch basket.

The kick start lever needs putting back in the correct position.

Today I had a spare hour, I fitted the generator engine cover then fitted the rotor, when I went to turn the engine over it had become very hard to do so.

I took of the rotor and soon found the problem, I had bought a set of stainless engine screws and had fitted them, the problem was the heads are too big and were hitting the rotor , I removed these two screws and found two old original cheese head screws that I had replaced on the D1 engine rebuild so I used these, no more binding engine.

might help some one else out.

Once this was sorted out I filled the engine up with oil as it is much easier to do this with the engine out of the frame.

I had that with mine too. It was the same situation with the Wipac rotor and with the Electrex one. There wasn't much difference in depth of the screw heads, only a mm or maybe even less, but enough to scratch the back of the rotor.

I forgot to mention, I sent an email to Amal enquiring about spare parts for the Amal 523/1 carb and the reply I got was this.

all the parts greyed out and with a red cross are not available.  I now have the body and float, all the other parts I need are not available. 223_523-1.jpg
