I thought it worthwhile to somehow piece together the drive train without the main body parts which houses the gearing. To get them in some semblance of order and position, I made a wooden stand to support the various parts as they are to be found. For obvious reasons, some parts are now not indicated and these have been marked with an asterisk. I hope this will be of use.
Note: This gearing set up is restricted to Wood / Metal cutting bandsaws with Serial Nos. BK 3605 up to BU 8779 (roughly spanning late 1955 through 1957).
Key to Picture. Items marked with asterisk * are not shown / not indicated in the picture. Retaining rings / special arc rings have not been indicated.
- This knob is termed a clutch and engages the DRIVE PULLEY when pushed in and vice versa.
- The DRIVE PULLEY which is utilised when the wood cutting speed is required.
- This is the BEARING NUT which secures the BEARING in the main body*.
- The drive shaft BEARING which is located on the main body, pulley side.
- Two SPRING WASHERS within the bearing cavity in the main body.
- The DRIVE GEAR.
- The CLUTCH which is housed within a hub on the DRIVE GEAR.
- This is a SLEEVE on the drive shaft*.
- The other drive shaft BEARING which is located in the main body, lower wheel side.
- The LOWER WHEEL.
- BEARING supporting the INTERMEDIATE GEAR and is housed within the cover* which attaches to the gearbox body.
- The INTERMEDIATE GEAR.
- The INTERMEDIATE GEAR SHAFT which is driven by the DRIVE GEAR.
- BEARING supporting the INTERMEDIATE GEAR and is housed within the gearbox body*.
- The PULLEY SHAFT which exits the gearbox body through an oil seal*.
- The BEARING supporting the PULLEY SHAFT which is located in the gearbox body*.
- The PULLEY SHAFT DRIVE GEAR which is driven by the INTERMEDIATE GEAR.
- The BEARING supporting the PULLEY SHAFT and is housed in the gearbox cover*.
Additionally, this diagram displays the gearing for some earlier Delta wood/metal bandsaws.
