New (well) parts have arrived so can kick this off again

Oddjob if you have on that would be great thank you

Tigger not sure I understand what you mean by grooves. Image below from shaft I removed from 500 (Had to do some dremel work to get the washer and 2/3rd gear out due to the damage) Are we talking the pink or blue in the image or am i way off.

Hi Oddjob,

Thank you for checking and getting back to me.

I was not aware of which way the lock and tab washers faced but after very close inspection from Triggers images I gather I had assembled incorrectly. Upon stripping down again I was still puzzled to why the second gear was stuck to shaft and difficult to remove so I made an effort to get this off and inspect further as you can read from above.

Will check the bag with all the clutch parts and also the photos I have when I stripped down and get back to you and thanks for the steer and advice.

On closer inspection of the pictures you sent over Trigger I was still wondering why the second gear (No 7 in parts list) was stuck. I gave it quite a few taps and got it off the shaft but guess what I found is not what I wanted to.

Image of the shaft where the second gear came off. Am I right in assuming this means it needs replacing ?





Then the gear itself -




I can only assume something has gone in and around here or am I off the mark ?

 

 

Roger that Tigger.

The one I took off has a kink in the middle like it was bent and then straightened. From the initial inspection of the engine I made a decision to strip down completely as I was very unsure about how well it had been assembled in the past. If recall at the start of this post I found a primary chain link in the oil pan and also terrible wear on cam, and cam head surface bearings.

I have 550 engine so will steal one of there and replace that one when I get around to the 550.

That is brilliant thank you very much.

Was going to ask second gear No7 in parts image did that come off easy enough as mine seems stuck.

Then for circlips any reason why not to use similar to below.



Washer with the tags that I have the wrong way round so thank you very much I will have to go and rectify that.

Bryan,

Thinking about again it must be as the spacer is the bearing looking think attached to the shaft itself. Now I never removed all the gears on that shaft as I could not figure out how to get No 7 off. Would it be best to try again and replace the o-ring or would I be good with that one.

Also any view on the extra washer that was on mainshaft ?

Need three things checking please as I hope some of these are correct but could do with a Jedi/Expert opinion to validate.

For the Countershaft assembly No 19 and No 20 on the image is the way I put these washer back correct



The way I put these back below but I am more interest in washer 20 to see if the turned pieces went in the correct way. No 19 I assumed is the flat washer and No No 20 the washer that has bent ears for the I/D piece.






The second thing I need checking is with the Mainshaft when I stripped it down there were 2 washers where No 18 is.



I started putting this back without the second washer. Below is what I found when I stripped the Main shaft down for cleaning.





The 3rd query is reading the Haynes manual when inserting the second drive it says - " Ensure that a new oil seal has been fitted to the secondary drive sprocket end of the layshaft and that a new O ring positioned behind the oil spacer" From the parts images above I can't see this O ring only the one that fits between the bearing and the fixed positioner on the mainshaft No 3.

page where I read this added below -



I did not remove the bearing No 22 all the way to No 7 only No 19 to No 24 for cleaning. So assume O ring No 27 is still there
