Yikes, that's a severe penalty. Heavier than the first H145 (the alloy one), yet far weaker than the alloy H190

I wonder if a 1200 would ride better with the alloy diff and softer leaf springs? Too bad we never got a proper monoleaf spring review

I weighed both the all steel H145 axle and the H190 with aluminum diff housing and brake drums. The H190 was only 2 pounds heavier.

I suppose this why some racers use the alloy B10 diff instead of the B110 cast iron unit

9kg!

Never weighed a B110 actual diff, but it felt like 15kg

5.14 ratio. Seems like a rare ratio

B110 used a cast iron differential carrier

Aside from the carrier case and bearing caps (with bolts), all the parts seem to be the same as the B10, except for the pinion crush sleeve. Datsun competition showed the gearsets interchanging

The case is part number 38310-G0400 COMP-CARRIER GEAR
G04 means designed for C20H 1970 Sunny Cab flatbed

Datsun Sunny 1000
B10 4.111 (37:9) sedan & coupe
B10 4.375 (35:8) van
B20 4.625 (37:8) truck

All use the same GEAR CARRIER part number 38310-18000


the bearing cap fit over studs and are secured with nuts

It also does not use the cheap crush sleeve that the cast iron H145 does, but instead has reusable shims

Now that's interesting. All B10

* In the B10 parts catalog, the diagram shows the alloy carrier
* In the B110 parts catalog, the diagram shows the cast iron carrier

Appreciate the kind words!

I don't want this forum to sink into the land of lost like many other of my other favourite forums back in the day so I am trying to add content that people will get use out of for years to come. Everything in this thread is hosted on an old Tumblr Account that I use/used solely for hosting images. I deem it safe as I can't imagine that website will be going anywhere in a hurry and also, its FREE (up yours Photobucket/Flickr)

You might have noticed I have added to the Techwiki as well, it is mostly just information that I am actively researching for myself that I think would be beneficial to be brought into 2025

Great! the sequence of photos pulling the engine is fantastic

100%, will be a long journey but keen to chip away at it

Did the usual things with the engine bay, deleted the battery tray. Forgot Spot Weld drill bits existed so made a dogs breakfast of it but learnt my lesson when I was decluttering the firewall










Pulled the Motor and Box out last night, first time ever messing around with a Datsun Automatic so it was a learning curve to detach it from the car so I could pull it all out as one unit












And luckily found a buyer instantly so I won't have it hanging around, straight into the Ute and dropping it off this morning to the buyer
