Servicing Saddle Spring Post

(To Identify Items and Part Numbers, Refer to Illus. 20)

Spring combinations with part numbers that make up saddle spring post assemblies, Part Nos., 3122-36, 3123-36, 3121-36, 3123-36A, 3125-36, are listed.

New motorcycles are furnished with standard saddle spring post assembly unless other than standard is specified on order.

The illustration shows following parts of saddle spring post assembly:

1. Spring tension adjusting nut.

2. Adjusting nut lock nut.

3. Rod nut lock nut.

5. Post clamp nut.

6. Saddle post rod.

7. Spring guide collars.

8. Plunger nut.

After raising saddle, remove saddle post clamp nut

(5), which is located underneath frame at bottom end of post tube. Post assembly can then be pulled out.

To disassemble saddle spring post, remove nuts (1, 2, 3, and 4), cushion springs and collars (7). Remove nut (8) from plunger and then saddle post rod

(6) and upper springs are free for removal. To re assemble, reverse operations of disassembly. To adjust cushion spring assembly (three lower springs), loosen lock nut (2) and turn adjusting nut (1) to right to increase spring tension; to left to decrease spring tension. If, however, considerable change in spring tension is required, a different set of springs to suit weight of rider will be required. Refer to Illus. 20 to determine spring combination needed.

Saddle spring post assemblies. Part Nos. 3121-36 and 3123-36A, use same spring combination but adjustment of cushion spring assemblies differs as shown in illustration.

When post assembly is inserted in frame tube, see that flat side machined on post rod nut (4) registers in flat side of hole in bottom of tube.

Ordinarily saddle spring post assembly will not need lubrication other than that given with grease gun at intervals given in Lubrication Chart. See "Lubrication Chart," Page 9.

If, however, spring combination is changed, any springs replaced, or springs anc' other parts cleaned, initial lubrication should be given by applying a liberal amount of Harley-Davidson grade "A" grease to springs and other moving parts.
