Inner Primary reinforcement

[Scrap]

RE: 57 FL. I was going to make a reinforcing ring for the motor sprocket end of my cracked inner tin. I see ready made rings for models up to 1954. What's the difference between a 54 and a 57? Would it be easy to make it fit?
Thanks,
Sam

I made mine for a 58 in a rigid & just took measurements.--The crack may be able to be welded & grinded?/-Unless its really fubared-up!/As I said before in the other post--Mine was not cracked -just seemed like a weak-spot to me then.--I have seen them real-old ones with no problems other then oil-tank tab,that needs a weld.IF its all lined-up with a straight-edge I don't see any problems--Unless RUST from sitting long.--(SWAP-MEET & then make a ring if you feel like!)--There cheap-enuff!--unless yours is the original oem & you are fond of it!--I can understand that totally!---RICHIE

Starting with the '55 model year the inner was no longer bolted solid to the engine but was designed to float to help prevent the cracking issues. The '55 up inner has oval slots instead of holes and the mounting hardware consists of a bolt with a spring washer and a thin spacer, along with a lock tab. When assembled properly the spring tension holds the cover to the case and allows movement. If bolted up solidly it will break, often more readily than an early one as there are no reinforcing ribs.

Thanks for the explanation, I had the tins chromed back in the 70's, no doubt by the time the parts came back I had forgotten how it was installed. I probably wondered what those extra springs were for when I was done.

Were they coil springs or spring tabs that were held by each bolt?
I am comparing it to the 60 I just tore down. The inner primary was not cracked anywhere and it had the spacers and tab type hold downs on the motor side and spring bolts on the rear 2 mounts. Just dont know if they changed again by 1960.

Spring tabs, sort of diamond shaped with rounded ends.

What is the order of assembly? I'm not sure what the lock washer tabs purchase to prevent the bolt from loosening. It seems like the order of assembly would be the spring clip 60652-55, then the spring, then the lock washer 6054-55, then the bolt. How tight should it be? Am I mistaken, because I don't see what is locking the bolt?

here's a pic of my 55

order of assembly is small spacer/spring plate/locking tab/bolt

I do not know whether the locking tab must be turned around, but in this position it locks the bolt

One more question, how tight do you compress the spring? Thanks for the photo, Palmers does not show it.

Tighten the bolt as normal, the spacer controls the spring tension.

Thanks to all for the answers and the great photo. What is it about the members of this site that separate's it from all the useless stuff on the web?

I agree about this site being the best!!

I have almost finished all the house repairs for the younguns house, and I will now have a bit of time to mess about with my project.

I will revisit my mounting of the inner primary, as I don't recall doing anything except bolting in up to the engine.........If I do find out that I did just bolt it directly.

These part numbers and photos will greatly assist .. and the parts will be on the list of items that I need for it.

PS, the rain in Portland has subsided for the time being..

George, FYI, the Colony part # 7812-12 contains everything, spring clips, spacers, lock tabs & bolts plus the springs, nuts, cotter pins and drilled bolts for the two rear mounting tabs.
