Dummie’s guide to carrier steering and brake adjustment please

[Lynn Eades]

I am guessing there may be a washer missing from under the bearing,or some other assembly fault, with your cam plate. The English/ Canadian carriers, have very little clearence for the bottom end of the clevis pins, but the Aust design allows more room, and hence have bigger dia. split pins, and longer ends to the clevis pins.
Your long clevis's are virtually rubbing on the floor.
Can one of you Aussie guys put up a parts breakdown for the cam plate, showing whats there is in the way of washers, spacers etc.
Ron, what you you tell us?

Thanks Lynn

Do you have any secrets for actually accessing the area?

Cheers

Im guessing that if you disconnect the brakes at the rear, then you can probably get full rotation of the cam plate. This in turn, may allow you better access to the pins in the long clevis's (j)

Hi Darryl &Lyn,
Lyn I think that you are correct, there is a washer missing from under the cam plate,and I would hazzaed a guess that The clevis pin is too long,and what you suggest regarding disconnecting the brake rods to test for movement is also the way to go,I think that I would also check to see if I was getting the same amount of movement in either direction of the cross shaft , Idealy I would remove the steering cam plate and give it a good check over, I realise that Darryls carrier has been rebuilt but the bearing might be buggered and not allowing enough movement,its not a big job and its best to look at all of the options,good luck Darryl keep us posted,
Regards to you both,Ron

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!

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
