Abstract

A method of assembling a gearcase cover assembly of a reciprocating saw. The method includes providing a gearcase cover with a cylindrical opening and a receiving portion, providing a shaft with a yoke affixed to the shaft, inserting a first end of the shaft into the cylindrical opening and rotating the shaft such that a second end of the shaft sits in the receiving portion.

First claim

What is claimed is:

1. A method of assembling a gearcase cover assembly of a reciprocating saw, the method comprising:
providing a gearcase cover with a cylindrical tube formed at a first end of the gearcase cover, the cylindrical tube having a first cylindrical opening; a receiving portion formed at a second end of the gearcase cover; and an intermediate cavity formed between the first cylindrical opening and the receiving portion;
providing a shaft with a yoke affixed to the shaft;
inserting a first end of the shaft into the first cylindrical opening such that the shaft extends through the cylindrical tube and out a second opening of the cylindrical tube opposed to the first opening;
receiving a bearing in the second opening of the cylindrical tube;
rotating the shaft such that a second end of the shaft sits in the receiving portion.

2. The method of assembling a gearcase cover assembly of a reciprocating saw according to claim 1 , wherein the shaft further comprises a bearing affixed thereto;
wherein the gearcase cover includes a bearing receiving portion; and
wherein the rotating the shaft includes rotating the shaft such that the bearing sits in the bearing receiving portion.

3. The method of assembling a gearcase cover assembly of a reciprocating saw according to claim 2 , further comprising securing a bearing cover to the gearcase cover.

4. The method of assembling a gearcase cover assembly of a reciprocating saw according to claim 3 , wherein the securing the bearing cover to the gearcase cover causes the shaft to be secured in the gearcase cover.

5. The method of assembling a gearcase cover assembly of a reciprocating saw according to claim 4 , wherein the bearing cover secures the bearing in the bearing receiving portion.

6. The method of assembling a gearcase cover assembly of a reciprocating saw according to claim 1 , further comprising assembling a blade clamp assembly to the first end of the shaft.

7. The method of assembling a gearcase cover assembly of a reciprocating saw according to claim 1 , further comprising forming the gearcase cover via casting.

8. The method of assembling a gearcase cover assembly of a reciprocating saw according to claim 7 , wherein the gearcase cover is cast of aluminum.

9. The method of assembling a gearcase cover assembly of a reciprocating saw according to claim 1 , further comprising securing a cover to an open portion of the gearcase cover.
