How not to B33!

[Dan_B33]

Hi Rog,
Nice one! Fully focused on the task!

Today I have received refund from AS Spares...(Oil pump drive).
They made no problems at all and all went smoothly.
I still consider buying from them in the future since looks like they care a lot about customers.

Cheers
Dan

Hello,
Back in the game!
Looks like that all has a chance to work!
Dry fit to check if I have enough play on the timing...and head sits freely on the barrel...tested Ok!

[Dan_B33]

Abou the clutch pushrod.
What is the length for 6 springs clutch 4 plates? Can I use swing arm model pushrod?
What would be safe to take?

[Dan_B33]

Just to add current it is 12" long.

[Dan_B33]

Looks like this one would be 1to1 replacement.

I could cut if too long right?

[Dan_B33]

But that was with 5 plates and would 11+12" (292mm) fit 4 plates?

[Rog1]

I would assume nothing and see whether the pushrod you have is at or close to the right length, before replacing it. If you need to, anneal the pushrod and shorten it until it's right, then measure it. You'll then be sure of the length and you can buy a new one.

Hi Rog,
I wish it was that easy with buying.
I have few bits waiting in UK for shipment to Poland....among them are clutch plates....so I would like to order and have it delivered all at once

[Rog1]

Some suppliers sell a pushrod that can be cut to length; only one end is hardened. Once at the right length it's an easy job to harden the cut end; I've done it myself. Here's one:

[Dan_B33]

Perfect!
Thanks a lot!

I have put engine together!
Engine rotates and oil flow work ok. I get knocking/ clicking noise when the valve spring is being released. When it is passin the highest point of a cam. Inlet makes considerably smaller noise. Clearance is set to 0.03inch. (0.008mm)

[Dan_B33]

Sorry 0.003inch which will be 0.008mm.
Is that clicking noise ok? I can't make engine running since I do not have operating Gearbox

[Roy]

Through my experience I would say it's quite normal to hear the clicking its the tension of valve spring trying to take up back lash in cam gears etc it will only do it when turned over slowly,Roy

[Dan_B33]

I hope that's the issue.
I will double check the free play on exhaust valve.
Manual says 0.003inch is a minimum...so guess better bi loose than too tight.

I was double checking the cams settings and dot side (exhaust) side is set wit the mark matching dot . Thel line mark however is not present o on the run (just on edge not sure if accurately) . How many teeth I shall have between dot and line markings?

[Rog1]

According to both the Haynes manual and the pdf of the owner's handbook on the BSAOC site, it should be 5 teeth, including the ones opposite the cam pinion dot and line markings. In your photo you have 6 teeth.

Plenty of helpful info in the member's section of the club website; I've used it often.
