Singles / 1959 c15 front wheel bearing
« on: 18 September, 2024, 18:04:46 »
Good evening,
My front wheel spindle seems to have side to side movement between the 2 bearings.
I can't see any spacers , so I assume one or both are not driven inwards enough.
How deep in is the nearside bearing driven in please , is there a shoulder similar to the off side bearing ?
Thank you

The original C15 is 7/8" bore inlet port , which will have a 375 monobloc to have a smooth pass for the gas whizzing from carb to inlet valve.
A concentric 600 series must be of the nearest metric equivalent to 7/8".
So if there are 25.4 mm to 1 inch , 7/8 equals about 22mm
So a 622 concentric , with suitable jets.
Ring Burlen in Salisbury to discuss.

Did you centralise the backplate when the wheel was put back into the bike.
Linings take a while to bed in anyway, put some miles on it and monitor any improvement.
Or failing that , if the linings/shoes are of dubious parentage , send the shoes for relying with "soft road" linings

This is the means of assembling and dismantling the inner cover.
Your dowel should have a split pin in the hole in its end.
Remove split pin
Remove dowel sliding it out

thats a regular place to leak Burlen do those fibre washers , but when you get them , check the quality of the faces the bottom of my main body was quite pocked and needed a careful facing square and decent - now dry
https://amalcarb.co.uk/monobloc-series/375-series/gaskets/gasket-sets.html about 6 quid plus post
if you're disturbing the carb off the head, have a you the fibre plate between the head and the carb , must have that
and if you dont know the history off the needle jet or needle then consider them as mentioned earlier in 1 of my posts to you
check also the truth of the carb flange face - -use a surface plate of piece of glass to ensure it is really flat - do NOT tighten the 2 flange nuts up stupidly tight - just enough
you should be there

Check your c15 owners manual or workshop manual , or speak to Burlen salisbury
The usual jets to wear are the needle jet and its needle - I'm not referring to the float needle , but the main needle and its corresponding jet.
A lifetime of use let's the needle waggle back and forth in its needle jet , making it oval.this will not cure any leak , only a bad mixture at that part of the throttle
Mine leaked or weeded from where the bottom jet block screwed up into the main body, even a new 2asher didn't cure it completely until I cleaned both faces up

Plug should be N5 or equivalent
Where is the leak actually coming from??
Is it the bottom jet block to main body ? If so may need the main body face truing and cleaning up, those faces often get damaged

you don't need to remove the sump plate or filter - just ease them off and let it (if any) dribble out

doesn't the brake plate get nipped up when all the rear wheel spindle nuts are tight ??
most of my backplates wobble a whisker and this is useful to centralise the brakes when putting wheels back (put brake on , hold it on, nip up wheel nuts
