Manual Diff Lock Install


Recommended Posts

Hi All

Been a long time since i posted anything useful here. 

So after many many years of searching high and low i have finally managed to lay my hands on a used specimen of Mr Macnamara's manual difflock.

The item in question is as seen in this leaflet of many years ago.

The axle it sat in was a mess to be honest, so i stripped it down and started to seek replacement bearings and seals. It also emerged that my locking shaft was junk.

So after some emails to Mr Macnamara i managed to source a new shaft, plus other bits and bobs to start my install.

I also had to modify a coiler hub since i have a disc brake conversion at the rear.

Talk about a blast from the past ......

Interesting this.

I have on the Series Hybrid a rear diff lock and it is useful at times.

Very interesting to see how this goes - please keep us informed.

Interesting thing, it's kinda how the Volvo one works except they use a vacuum-actuator to slide a dog down the extra-long spline.

Wonder if you could use a concentric clutch release bearing to actuate it without having to stop & get the spanners out?

Thanks for the prompt reply Gremlin,

My version is the earlier one contained within the rover style diff.

I am hoping to put it under a 1959 SWB.

I have emailed Mcnamara to see if they still have any stock of the long bolt and dust cover bolt.

In the meantime I will test a few metric bolts for compatibility

I suspect that a PO may have sheared the original bolt off leaving the end in the half shaft. I will find out for sure when i strip it down.

Did Mcnamara have the new shaft in stock or did they make you up a new one?

Thanks

Jamie

Well you could come up with something, but that will add complexity. This is nice and simple.

 

Just remember to do it before that end of your axle is stuck elbow-deep in a swamp somewhere :D
