Cam follower worn half way CD-11

[crosbyman]

I found the cam follower  of the carb on my CD11 pretty worn  down almost 50% from simply rubbing against the cam over it’s  65 years of life .

I filled in the gouge with  steel epoxy but I know it won’t last.. but it felt good 🙂

 

Barring finding and  installing  a new L shaped rod ….would installing & gluing   a  small piece of   5mm ID SS tubing

over the worn area suffice as a remedy ?

 

thanks for comments

So, it is the cam follower that is worn, not the cam itself?  I’ve seen lots of worn cams but the follower would be unusual.  Whatever, I wouldn’t expect the follower to be that hard to find.  Heck, there are a couple of them lying on my workbench right now.  I’d be glad to send you one, free, but the postage to Canada might be more than the part is worth if you can find one locally.

Yes it is the follower  (see pict.) that is worn… odd because it looks like SS and should have been a harder metal than the cam itself.  I’ll check locally  (Adam?? maybe 🙂 )

Thanks for the offer   much appreciated .. in the mean time  can you check $$$  to mail to Canada postal code h4h 2c4 I would be glad to transfer the funds

The cam follower is made deliberately softer than the cam — it’s by design to ensure the cam itself  doesn’t wear out.

Odd because it does look like stainless steel  and like Frank, I have seen cam wear more than  camm follower wear…..  but anything possible I guess.

I any event for $3 cdn,  I found a nice   8”  X 1/4” OD brake line with perfect sized  ID to slide over  my 3/16  cam follower shaft where I applied my steel epoxy  to fill the gouge.

I will  just cut a short piece  of tubing and slide it over the cam  follower  with a touch of  epoxy glue  and adjust the cam accordingly.

the followwer return spring will be  replaced  for a more softer one to reduce needless fiction between   the cam and cam follower.

should last long enough before I kick the habit. 🙂

 

thanks all for comment and  FR’s offer 🙂

Looks like about US$15.00 postage.  That’s awful.  Or I’m getting too old.

I don’t see why it wouldn’t work as long as there is enough adjustment left in the cam for the extra thickness. Filling the groove with a hard epoxy first would give some backing for the thin wall tube to. Better yet, a quick TIG weld using stainless filler rod would be the ultimate fix.

The 7.5 motors with the brass follower seem to wear more than the 5.5’s stainless follower and I have brazed them up in the past before reshaping them. Replacing the original follower with a later style one with a roller might be an option to. Can’t say cause I’ve never tried it but the matching cam would be needed to. There were at least four different cams used on these motors over the years so matching the part numbers would be a must.

Well a spare would be nice,   TIG welding one is  way beyond my skill and tool kit  level   so  “brake line tubing”  is it for now. . IF any problems develop I’ll attend to them  in late april or may  when I fire up  this  oldy.

I like my turtle 9622a  along side my ETEC 75  but this oldy  may get a new life as my kicker.  That should get folks smiling

Not to worried about the thickness on the  tube I will slide on…. the wall being about 1/16th  anyway . I am certain the cam can be  adjusted enough to compensate for it.

how about just lubing the tub and let it roll.

We had several green 5.5hp Johnsons at our resort and the cam followers were worn I never changed them but would adjust them when I was syncronizing the spark carb timing .The roller was a great idea on the latter motors.
