Dummie’s guide to carrier steering and brake adjustment please

Hi Ron and Lynn,

Thanks for the replies. I will give your suggestions a go and come back to you. My biggest problem is going to be squeezing into that little gap again!

Cheers

Gidday Lynn and Ron (and anyone else),

Just wondering if I can get some more advice about how best to attack this problem I have.

No matter what I do I can’t seem to squeeze into the right rear crew area enough to get anywhere near the clevis holding screw on the left side.
I figure I have two options to deal with the problem:

1. I undo the castellated nut on the cam securing bolt and then remove the full inspection plate from underneath the hull. I’ve had ‘a play’ with this option already but unfortunately I am not dealing with simple bolt holes tapped into the hull. Some bots are secured by nuts on the inside of the hull, again in a very tight area to access.

I figure if I can remove the plate (correct me if I am wrong) this plate and the plate with the cam securing shaft will fall away leaving the cam still inside the hull and still secured to the steering column by the connecting rods and clevises.

Then, I find a suitable washer or some other spacer and fit it to the cam shaft and simply replace the assembly.

That should give the cam a couple of mm of lift which should mean the clevis will clear the metal plate it is currently striking.

Alternatively, I just remove the plate with the cam securing shaft and follow the same procedure above. I haven’t really looked hard at this option and from what I recall I will have to rotate the cam until I can access each of the four nuts so as to remove the four securing bolts.

Am I on the right track here?


2. I get a small suitably bladed grinder or something similar and after removing the driver’s seat I access the very small hole in the bulkhead and see if I can grind 1-2 mm off the plate on the hull just under where the left side clevis will slide.

I figure this will be a mission in itself and will be reliant on getting a suitable grinder or some other appropriate tool. It really needs to be about the size of a file but be able to take off the required couple of mm in that plate in a very confined space.

Any other thoughts on how I attack this?

Cheers

Hi Darryl
I think that I would remove the entire assembley by disconecting the rods and dropping out the plate, its possable that one of the clevis arms may be bent a little and allowing the leading edge to contact the front edge of the cam area,if you get the entire plate out and on the bench you can then see how it all works and also see what is causing it to bind, I know that it is a bugger of a job but if you do it right you only have to do it once, I have had this sort of problem a couple of times over the last thirty years,and it is easy to fix if you have the cam plate and clevis rods out all in one piece, I will say that I have no knowledge of the Canadian carriers, I have only ever restored Australian ones,but quite a few of them
Good luck Regards Ron

Hi Ron,

Thanks for the reply. I have an Australian carrier.

Removing the whole assembly is also my preferred option but how to do it is the problem. I can't reach the fixing screw for the left side clevis, let alone the nuts which secure the bolts on the left side of the large underside cam plate.

Is there a secret to how to access everything that I am missing?

That is why I wondered if just undoing the four bolts which secure the plate holding the cam shaft might be enough. I figure if I was able to at least drop this plate out I could fit a suitable spacer on the cam shaft to raise the profile of the cam a little.

My size is probably not conducive to that wee gap in the right crew area.

Cheers

Darryl

Ron, the differences are only in the detail.
Darryl. Try unscrewing the rods (647-6) from the long clevis's(there should be a lock nut)
Then you should be able to drop the cam plate out from the bottom. Once you have lowered the whole deal down enough to clear the cam plate rollers, you should be able to tip it back at an angle, and the plate, with the cam plate on it, and the two long clevis's attached , should fall out.

Hi Darryl, I know too many cooks in the kitchen spoil the broth but if it were me, I would disconnect both clevis's from the steering column then using mutigrips or similar, unscrew the entire rods out of the cam end. This will leave only the clevis there. Then providing you can remove all the bolts underneath the cam assembly, you should be able to remove the cam plate quite easily. It may be useful to losen the cam followers using the escentric bolts, then readjust after replacement and servicing. If the bearings are shot you can buy them off the shelf. I can give you the modernday bearing numbers if required.

colin.

Hi Darryl
There are 12 bolts holding the cam plate in position attached to the underside of the carrier, if you do as Colin suggests regarding the rods, and as Lyn says regarding tilting the back of the plate downwards on its rear end it will slide out, I knew what I was trying to say but guess that it did not come out the way that I wanted it too,thanks fellows this is what our hobby is all about,and thats sharing information,
Regard Ron
