JUNIOR SCOUT TIRES
When applying new 18″ x 3.30″ tires to Junior Scouts it is sometimes difficult to get the bead of the tire to completely fill the clincher of the rim. This results in tire wobble.
This condition may be corrected by applying a strong solution of water and Murphy’ s Oil Soap to the clincher of the rim before the new tire is installed. Murphy’ s Oil Soap may be purchased in one pound tins from the Phoenix Oil Company, Cleveland, Ohio.
THE 1938 OIL PUMP
We have received many requests for information on adjusting the 1938 oil pump for models 338 and 638. No adjustment is provided or required. The capacity of the return oil pump is so much greater than the feed pump that the sump is clean at all times and no reduction in feed pump capacity is necessary.
CONVERTING 1934 and 1935 OIL PUMPS ON 74s TO THE
1937 OIL PUMP
Some dealers and riders are confused when making the above oil pump conversion. The necessary material and operations for this conversion are as follows:
Two different pump bodies were used in 1934 – 85278 for 7/16 diameter feed plunger and 74623 for 3/8″ diameter feed plunger. All 1935 machines used 74623 bodies. If you have a pump body with 7/16 diameter feed plunger hole it will be necessary to order a new body 74623.
|Use 1 – 40900||Pump plunger – 1937|
|Use 1 – 37279||Plunger guide screw|
|Use 1 – 40833||Guide screw roller|
|Use 1 – 40509||Cam shaft – front|
It will also be necessary to replace front cam shaft bushings in both crankcase and cam case cover.
|Use 1 – 40455||Cam bushing in crankcase|
