Velvet Drive 1004 and 1005 V-drive parts diagram
This is the factory exploded view of the Velvet Drive 71C and 72C V-drive, the 1004 (71C, tags 10-04) and the 1005 (72C, tags 10-05). It comes from Borg-Warner's V-drive service manual, which draws the unit in two parts: the transmission (Figure 10) and the V-drive gearbox bolted behind it (Figure 12). The gearbox items are shown as V1 to V49 so they don't mix with the transmission's 1 to 82. Tap any part to see its factory part number and which kits include it. If we stock it, you can order it right from the part.
The two drawings have 129 numbered items, and the model charts list 24 model numbers. 128 of the part numbers are in our online store. Hale Marine is an official Velvet Drive distributor, in business since 1953.

Find your model number
The model number is on the identification plate. One that starts 10-04 is a 71C V-drive (1004), and 10-05 is a 72C V-drive (1005). We often write it short, so 10-04-000-011 and 1004-011 are the same unit.
Every 1004 uses the same transmission section, 10-04-410-001, and every 1005 uses 10-05-410-001. The ratio comes from the V-drive gearbox, which carries the same last three digits (13-08-410-011 on a 1004-011). Type your model number in the box above and the gearbox parts switch to your ratio.

Gear drive or chain drive
The gearbox is built either with a pair of gears or with two sprockets and a chain. The gears or sprockets set the ratio (V21 and V30), and a few other parts change with the drive: the case (V11), the gear spacers (V19 and V29), the chain (V22) and the oil baffle (V36).
The factory list gives gears for 1.99, 1.51, 2.49 and 1.21:1, and sprockets or a chain for 1.98, 1.53, 2.50, 1.21, 0.97 and 3.10:1. Both drives were made at 1.21:1, and the model chart doesn't say which drive each 1.21:1 model has, so those parts show both versions. For the other ratios the list only says "ratio no longer available". Call us with your model number for any of these.
1004 or 1005: the parts that differ
The gearbox is the same on both. In the transmission (Figure 10), these 17 items take a different part number on a 1005. The forward clutch pack kit is different too: A4867AE for 10-04 units, A4867AB for 10-05 units.

Common questions
Is a 1004 the same as a 71C?
It's a 71C with a V-drive gearbox bolted on. About 65 percent of the transmission's part numbers match the in-line 71C, but the model number starts 10-04 instead of 10-17 and some parts are V-drive only. A 1005 is the same idea on a 72C.
Where's the ratio set?
In the V-drive gearbox. Every 1004 uses the same transmission section, 10-04-410-001, and every 1005 uses 10-05-410-001.
Is my V-drive gear drive or chain drive?
The ratio usually tells you: the factory list gives gears for 1.99, 1.51 and 2.49:1 and sprockets for 1.98, 1.53 and 2.50:1. Both were made at 1.21:1. If you're not sure, call us with the model number.
Does the transmission come with the coupling?
No. The factory doesn't supply the coupling (item 80) with the transmission or the V-drive gearbox. Order it separately.
What does NSS mean in the parts list?
Not serviced separately. The factory doesn't sell that part alone, so you buy the next assembly up.
What if the part isn't in your online store?
Call (804) 333-3677, Monday to Friday 9 to 3 Eastern, or email sales@halemarine.com with the part number.
More on the 1004 and 1005
The 1004 and 1005 are Velvet Drive's cast-iron V-drives, built on the 71C and 72C. Read about the 1004 and 1005, see the in-line 71C and 72C parts diagram, or shop 71 Series and 72 Series parts.
Not sure which you have? See how to read a Velvet Drive ID tag.
The drawings and part numbers come from the Borg-Warner Velvet Drive 71C and 72C V-drive service manual, Figures 10 and 12. Older units can use different parts, so check the number on your identification plate or call us before you order.
