Correction...its a Series III Gear box in my IIA

[IHMS]

Hi Again,
Well as it turns out, my local Rover specialist says my late 1969 IIA may have been one of the first Rovers in Thailand to receive the Heavy Duty Upgraded all syncro Series III gear box! I was happy to see that. This may also explain the curious "D" at the end of my VIN number.

Anyway, I have the rover part numbers for the bearings and seals...but not the corresponding manufacturers numbers, i.e. Timken, SKF, Fag or British, etc. I have a few, but I was hoping someone might have them laying around and wouldnt mind posting them. I am sure the reason why they are not in any Official Land Rover literature, is because they want us to buy from the Land Rover dealers parts department...cant blame them. Both Timken and SKF manufacture here in Thailand, and I know I can get them right off the shelf if I had the numbers. When I do finally get them I promise to post them!!

First, the IIa gearbox is more rugged than the III. It was not uncommon for people doing Perkins conversions to put the IIa multipart layshaft in their SIII box.

You can get the bearing numbers off of the bearings and races when you pull the gearbox apart.

I will take a look in my dad's bearing books and tell you what I find.

I have a few part numbers for a SIII box (at least as much as I can see faint half-worn-off part numbers):
Rover 1645 corresponds to RHP 6307 or SH 6307R
Rover 55714 = Timkin TKR 8084
528701 = NTN 6305 (or 6305C3)
RTC1412 = Timkin TKR3040 or RHP LRJA7/8
