Humber FV1600 - ARN 105-819 - Restoration moves forward.

Well, we have placed about 250 K's on the old girl and she has developed a harmonic type noise at about 48KPH when not under load. Tested the drive train by running her at speed whilst sitting on Safety Stands. Thought it was coming from the transfer case so removed it and disassembled only to find nothing that could be causing the noise. Upon further inspection I found the following;

1. Pinion Dog Gear and securing Nut which was not tight.
2. A marvel of design the Pinion Carrier so easy to remove once you have access.
3. Pinion carrier being removed from the diff housing.
4. The culprit (I think) worn pinion teeth.

To wrap up a long and frustrating story I have sourced a NOS Transfer case and another Pinion in which I will try to mate to the crownwheel and cross my fingers that I get a good tooth pattern and no binding.

I will pick up the parts this Saturday and hopefully get Sunday to play around with them. I am pretty lucky to pick up a NOS transfer case a short 3.5 hour drive from home.

Cheers,

Dave.
