Title: A65 rebuild
Post by: MITCHELL on 02 April, 2017, 21:23:52
Firstly thanks to everyone for the advice on getting the bike registered,especially Steve Foden,I received a v5 with the original reg no a couple of weeks back, well chuffed I have to say.
    The frame and other bits are back from powder coating and assembly about to start, I read in the manual that fitting new  bushes into the swinging arm should be done by a specialist, is this the case, or have things changed since this manual?

HI THERE
I FITTED SWINGING ARM BUSHES MYSELF WITH GREAT DIFFICULTY AS THEY ARE USUALLY VERY TIGHT TO GO IN >
I USED A LENGTH OF HALF INCH OR SIMILAR SCREWED ROD AND NUTS USING SOCKETS AND LARGE WASHERS TO FIT
AND PULLED THEM IN SIMILAR TO HOW YOU WOULD FIT SMALL END BUSHES > A LITTLE TIP IS TO SMOOTH DOWN
THE ROUGH FINISH OF THE BUSHES WITH A STRIP OF EMERY  AND USE OIL ON BOTH SURFACES  TO EASE THINGS
A LITTLE > REMEMBER TO REMOVE ANY POWDER COATING ON THE INSIDE OF THE SWINGING ARM BUSH HOLE >
IT CAN BE DONE REGARDS JOHNBOY .

 Hi John, thanks for your advice, I was thinking along the same lines----- a length of screwed rod nuts and washers ect,I suppose keeping it all in line may get a bit fiddly, but with a bit of patients I reckon I'll be ok, cheers, Dave.

 :) Hi

The method suggested works a treat, but I usually slightly bevel/chamfer the leading end then put them in the freezer overnight which will contract them by an invisible amount, but it can make a difference.

Enjoy

Mike

Ah, good tip, plus if I put the swinging arm on top of the boiler that should help a bit too, unfortunately c d said today there's a size problem with the bushes they have and are waiting for their supplier to rectify, so not going to be this weekend anyway.

Evening all,moving on to wheel rebuilds,I've started rebuilding the hubs and have a couple of questions all ready,firstly the new bearings have a plastic grease retainer fitted in them, would I be right in thinking therefore I don't need the rubber ones mentioned in the manual, secondly on the front hub having fitted the second bearing how do you know when it's fully home, mine seemed to be there but when I screw the retaining nut up its still proud, not much, about 1mm at the most but is that going to cause me a problem later?, more quiries on the rear hub later, I'd like to get the front right first, cheers, Dave.

Hi Mitchell,
                  I think you are referring to the rubber 67-6051 on the rear wheel? If so I always use it to keep the dirt out even with sealed bearings.

   When fitting the bearings on the front, the nearside is home when you can fit the circlip with ease. The offside I fit the bearing fully home on the shaft, fit into the hub, then fit the bearing retaining ring ensuring it is fully into the hub. I get a experienced 'feel' that all is correct from a solid sound when tapped with a light hammer. When you fit the brake plate and tighten up, check the assembly ensuring the nut is fully home, the brake plate turns freely and is fully inserted. When you fit the wheel in the forks, it should be central.

Freeze the components that fit inside and heat the components that are outside.

Best wishes...

Hi, I'm going for new rims ect, the old ones are steel " Jones " 18", they're pretty rusty, but before I Chuck them I thought I'd better check in case they may be of use to anyone.
