Title: 1959 BSA Super Rocket Oil Change
Post by: TonUpTrav on 10.08. 2013 02:55
I recently purchased a 1959 Super Rocket. I'm wanting to change the oil this weekend.  Are there any good resources on the Internet to find the proper method for oil change for a bike like this?  How much oil does this year take, filter locations, etc.

Thanks for the help,
Travis

Just thought I'd put in my tuppence worth Travis before others jump in with oil change info.....since you've just bought this bike it is essential that you include the removal of the oil tank and clean out the old oil in the tank AND any gunge that may/will have settled at the bottom of the tank. This isn't something you should necessarily do at each oil change but if I were you I'd start ownership with the bike knowing you've done this since it is often neglected by owners and draining the oil tank by just removing the filter/gauze assembly at the front bottom of the tank doesn't drain the accumulated gunge at the bottom of the tank which can affect the oil flow to the engine.

G'day TTT.
Wise words Alan. Also the sump plate strainer. G/box and primary too.

Hi Travis
Sound advice on cleaning the oil tank, regarding oil capacity its 5.1/2 pints, I would recommend a "Classic" type specification oil and not the modern oils. Your choice on mono or multi grade, a lot depends on your location and condition of the engine. I would avoid the use of engine flushing solutions.
The A10 is a dry sump system and is operated by a double gear pump retained in the timing cover, there is a wire mesh filter in the oil tank and another in the sump plate drain, both should be cleaned.
Many owners fit additional filtration in the form of ."Inline" return line filters of the cartridge type.
Enjoy your A10

Good enough. At each oil change, I use a big syringe with a bit of tube on the end to extract the residue of oil from the bottom of the oil tank. A surprising amount lurks there.

Travis (I assume),

Now that Muskrat has you (rightly) taking off the bottom sump plate to clean the strainer, examine what lies on top of it and, I recommend,  report back here before reassembly. You'll want to know what kind of metal bits lie there, if any. We'll assume you have a stock sump plate, so a lot of oil will probably spill out when you remove it. Regardless of giving your hands an oil bath, try to keep the plate level as you remove it so that any telltale bits don't wash out of view. The main thing you'll be looking for is shards of shim material used between the drive-side main bearing and the crank web.  If your sump plate is indeed stock, consider replacing it with one from SRM that includes a drain plug.

The original post is four and a half years old. I doubt TonUpTrav has been waiting all this time to get all our replies.

But goes to show really old posts are helping others. Worth a bump.

 I put this in the wrong thread *bash, but now moved here;

 Unless others are different to mine, there's also about 70ml trapped in the oil-pump cavity that can only drain by removing the cover- unless you do what I did and drill a hole in the bottom rear screw boss (as in pic). I get the front wheel up and wedge the centre stand so it leans the bike a bit to the left and back (need a custom something to catch the oil without running over the header pipe though). I also poke a wire in the scavenge pipe to hold the ball away so it drains too.
