Hello,
As above..I'm after a black or brown speedo drive gear if anyone's got one that's not chewed to oblivion, thanks. Dave

b20 with d type o/d retrofitted. From p1800. 4.30 rear axle. 19 or 20 teeth. I say brown also because I have heard this was a replacement for the black ones.

If the donor P1800 (B18) had Smiths instruments it would have a black fine toothed gear with 19 teeth. Part #380305 Price I have noted is/was £34.73. On the P1800 it would normally be used in conjunction with a right angled drive. Not needed on an Amazon as there is more space and the routing is easier for the speedo drive. The cable for M41 is about 77" long, about 15" longer than the M40 box one.
Later P1800 (B20) would normally have a J type OD, and when used with 4.30 axle the speedo gear has 20 teeth and is again black, part #380753. Not sure if this is also fine toothed but would seem reasonable being that the coarse toothed ones used on the Amazon which has a VDO speedo are all coloured. A genuine Volvo gear should have the part number on the top face. Can you make out the number on yours? The fine toothed drive gear on the output shaft can be swapped over for a course one if needed. |
