Hi Ted,

Where do you get the industrial paint stripper? All info says this is hard to get?

There is a local place 3mins from here that will do acid dip and vapour blasting, so will hit them up for a quote.

The transmy countershaft has some corrosion, and it has a seal that isn't listed separately in the manual. Assume this is cleaned up and left as is generally?

I’d go for Synstryp….it’s very effective.

Some e-bay sellers want proof of industrial use etc. If you have a decent Automotive paint wholesaler nearby just turn up in your overalls. It is nasty stuff so you must take appropriate safety measures.

Regarding your rusty output shaft end - I soaked my end bit in Evaporust. Sounds like Snake Oil but it works without eating onto the steel as it works by breaking the bond between good steel & the rust + iron oxide. I then dipped the clean part in gun blueing to passivate it.

I'm gonna admit being a total dummy.

I did not notice the parts book, only the user/owners manual.
I've been using CSMNL for parts lists, but the books look to be much better source.

David.... Could you read your emails please. Ta

Have some evaporust so will give this a go. Not done gun gun blueing before though, will do a bit of reading.

Hi Julie, have replied 👍

Hi all, taking apart the starter motor I noticed a lot of residue inside the cover. Is this normal?

Also, looking at replacing o-rings there are two in the covers and housing but the parts list on shows only (the one outside the main housing. The one located on the rotor shaft cover isn't listed - are these the same?

Finally, I need to replace the rubber boots and insulation on the cable. I've seen a thread where the cable is replaced and uses a 6mm thread stud, but that was due to the cable being cut. I plan stripping the insulation and using high kV rated heat shrink. Wondering if people have done this by other ways?

Thanks!

Just done a couple of starter motors. I swapped the original cable method with what you describe, a simple stainless steel nut and bolt, I used a socket bolt for clearance inside the starter motor.

Debris inside the casings is common, it's the residue of the carbon brushes inside.

If you look at the 500 parts book instead of the 550K3 one, same starter motor essentially, then it gives the dimensions of both, I know I just bought a load of them as I have 5 or 6 starter motors to refurbish.

Seeing this is common BTW



Not a great idea to leave it like that as a couple of the strands are close to touching the motor body.

I cleaned up everything, totally dismantled the motor including taking the windings out of the body, cleaning the armature etc, replaced the screws holding the windings onto the body with stainless ones, removed the rust from the winding supports, removed all damage from end caps and resprayed with Simoniz silver paint etc

Came out like this





The cable was a temporary one I made to replace the battery to solenoid, I also found somewhere selling the rubber boots but that was after I took the pics, I'll cover the connectors with shrink wrap later as well.

Wow, that looks mint!

I was just going to give it a clean / tidy up but now I'm inspired to do the same! I'll look at the 500 book as suggested.

Cable/strands look ok to be honest, just need to clean up the insulation at the body as it has the same exposed section.

Looks neat Ken.👍👍👍

Hi all,

I'm currently compiling a list of "wearable" items in the engine that I need to replace, including all seals, gaskets, o-ring, bearings, etc...

I have taken look through the Vesrah kit parts list and compared it to the part numbers in the CB550K3 parts book - the only item that doesn't match is "11394-390-306 - Crankcase Cover Gasket - x1" where the parts book for both the CB550K3 (E-7 Item2) and 1975 CB550F2 (E-6 Item2) says it's 11394-390-300?

Finally, with a list of 58 items that I've identified that should be replaced in the engine, just wondering which of the parts books would be the better source to getting correct parts?

[Oddjob]

The change in number doesn't mean much in that case, it can mean a change in manufacturer, a change in composition, maybe a harder rubber etc. If it was a major change they'd have changed the part number or the middle number and recalled all the F2s so they could change those.

If it's a 500 stay with the 500 book, same as 550, F stay with the F book and K stay with the K book.

[juitz]

Thanks! Mine is a K1 but not sure what was changed between K1 and K3.

Any recommendations for clutch friction plates. I'm thinking EBC?

[Oddjob]

Nothing wrong with standard OE plates IMO.

What's wrong with the plates you have now?

[Bryanj]

All 500 are same but two different set ups on 550 depending on year and wether it has the double steel plate
