To fit the rocker arm bearing assembly, it is necessary to press out the old outer bearing race and side washers, and press in the new outer bearing.
To do this really requires some form of press (although I am sure the correct spacers and a good vice could also do the job!). Then once fitted, the outer bearing should really be honed, as it is inclined to close up fractionally as part of the pressing in process.
With this in mind I offer a service to take your old rocker arm (which you should post to me fully insured), and I will fit and hone the complete bearing assembly. The rocker arm will be sent back to you with the bearing assembled and honed, side washers fitted and the assembly lubricated with castor oil. (Please note though, the cost quoted is for a standard rocker arm supplied to us bare, having had the old bearing removed, other than the outer sleeve - which we can remove when fitting the new one.
If anything is non standard that requires resolution or repair - we may not be able to carry out that work - so please confirm before hand. This service is for the fitting of the new rocker bearings only - it does not include fitting of rocker pads, 3 piece adjusters or any other work on the rocker arm. Price is per Rocker Arm. Postage back to you will be additional to this, and the rocker arm will be sent back to you fully insured at cost.
Please Note: Do not send rockers without contacting us first! If you place an order for this service we will email you back to confirm the availabiliy, as it may be some time before we can carry out the service. It is also a good idea to send photos of the rocker arms first so we can correct they are the right type and original, to have this operation on them (there were different types of rockers fitted in the early years with different diameter rocker bearings.
Note: this honing service is carried out on a professional honing machine - a Delapena Speedhone, probably very similar to the one used by Norton's themselves!
