Installation Instructions
This conversion kit includes all of the parts necessary to convert a 1971 Commando or 1972 Commando to incorporate the cartridge type full flow oil filter. This unit is fitted as standard on a Commando with engine number 208754 or above. This kit can be used on most bikes if it is modified.
Assembly Instructions
1. Drain the engine oil into a suitable receptacle from the drain plug at the bottom of the oil tank.
2. Slacken the clip and remove the existing oil return pipe from the stub at the rear of the oil tank and the oil junction block inboard pipe.
3. Connect both of the new shorter oil return pipes to the oil filter mounting head and secure with the screw type clips provided.
4. Drill two 11/32", (87mm), holes to the mount the oil filter assembly at the right hand rear of the engine plate, see over, this shows the filter and securing hardware in position. Note that the filter must clear the swinging arm in its lowest position. The location of the filter mounting, rearwards of the gearbox shell, will be seen. The position for drilling the holes is shown over, this is given as a guide only. This is the position used during assembly at the factory, but it is purely arbitrary. It may be found simpler to use the mounting screw tab washers as a template during drilling.
5. Fit the spin on oil filter to the mounting head and hand tighten.
6. Hold the mounting head to the inside of the engine plate and locate both screws through the lockplate, tab washer and engine plate into the mounting head tapped holes. Secure to a torque of 10
ft.lbs. (1.383kg.m.), and bend over one corner of the lockplate to a flat on each screw head.
7. Using a suitable strap wrench, check that the filter element is securely tightened then fit the large screw clip and secure to prevent the element slackening off.
8. Slide the protection springs over both new oil return pipes.
9. Route the kickstart side oil return pipe through the space between the engine plate and rear of the gear box casing, over the top of the gear box inner cover and engage to the inboard oil junction block pipe at least 1.25", (32mm), securing with the large jubilee clip.
10.Route the inner oil return pipe vertically past the rear of the isolastic mounting tube, connecting up to the stub on the rear of the oil tank and securing with the small jubilee clip.
11. Refill the oil tank to level.
Maintenance
The filter should be changed on a new motorcycle at the 500 mile service. The regular period for changing the oil filter after this is every 5000 miles.
To replace the filter, slacken and remove the large jubilee clip. Place an oil drip tray below the filter and unscrew the filter counter clockwise either by the use of the strap wrench or piercing the thin metal filter casing with a sharp implement such as a strong screwdriver and turning to slacken. The filter will be badly damaged this way, but it is not intended to be re-used. Ensure that the old rubber sealing ring has come away with the cartridge, if not, remove it now. Lightly moisten the sealing ring of the new oil filter with oil and place into position, tighten the new filter into place with a strap wrench. Re-fit and tighten the screw clip around the filter and the retaining strip.
