Lazarus 2A Ambulance

Hello All,

How can I identify what suffix gear box that was fitted to Lazarus made in 1963. The serial numbers I found are just too removable and exchangeable for comfort.

I found a number stamped into the top cover of Lazarus' gear box. It is 25142397 B. The "B" suggests the gear box is a Suffix "B" .


I also found a number on the transfer case HDA2 on the top and 528675 on the bottom line. My concern is that the top cover that holds the gear selecting rods and the transfer case are both removable items.

Lazarus is an Army Ambulance - then had decades of civilian usage, so there have been plenty of opportunities to exchange parts that may not be true to stamped code numbers located on highly exchangeable casings.

Kind regards
Lionel

The gearbox should be suffix 'B' from your information, but as you point out this does not necessarily mean all the parts in it are (and that includes the transfer case).

I would order parts based on the number, but when ordering, ensure you can swap for the correct part if the ones you get are different from what you are replacing!

Hello All,

I am trying to loosen a Series 2A Primary Pinion Locknut that was factory fitted to gear boxes from 1948-71.

Am I correct in thinking that Primary Pinion Locknut Part Number 213416 is a Left-Hand Thread? As in turning the nut clock-wise loosens it and following the more frequent approach of turning the nut anti-clockwise actually tightens the nut?

I have attached a photograph of the wee beastie

Hello John,

Thank you for the confirmation about the thread being left-handed. Even quoted from the set of manuals. My set is still missing in action .

I will set aside some time to track them down in the near future. I now have added impetus to do so; as it is best to attempt to avoid costly mistakes... Around about $88 plus postage in Australia for a new lock nut according to the online parts sites. Then to make one of the "special tools" out of a sacrificial impact socket

That particular nut, on the input gear, the manual actually shows a hammer and punch as the special tool! And an old clutch plate to hold the shaft.

Hello John,

The manual showing a hammer and punch is very interesting.

On my previous searches on the internet for information about the handedness of the thread on the Primary Pinion Locknut ... and to find a replacement nut... I found this: Part Number HNJ5000000 - Land Rover Series Gearbox Primary Pinion Nut Tool. They are the engineering mob who also make replacement locknuts Manufactured in the UK from AISI4340 (EN24T) to a higher quality than the genuine Land Rover part. Accessed 1st of February 2020 from: https://www.hnjengineering.co.uk/pag...j5000000_4.jpg

I like how they put arrows showing the direction of turn to untighten the nut! Doh! (Homer Simpson)

Hello All,

After some going down false trails and some rummaging around.... I am reunited with my set of Series II & IIA Land-Rover Workshop Manual Part One and Part Two. 1st Edition March 1969.

I was given the Workshop Manuals when I bought my Series III 109 "Rebus". They were taken out of the cabin where they were stored by the previous owner on the passenger side floor. I parked Rebus outside and it rained. I was not familiar with the waterproof properties of Series Land Rovers... or lack thereof. Subsequently, the manuals got wet and were left to dry out for a while before being stored in a safe place....noooooooo!

Flicking through the pages I found tell-tale signs of on-the-job usage. Grotty finger prints. The most evidently well used pages were...

Page 6-C Gearbox Section C Land Rover and Page 7-C with some SKF bearing numbers written in using blue pen.

Now I am just looking for the pages that mention the left-hand thread on the lock nut for the primary pinion shaft.

Yes, I got the said lock nut for the primary pinion shaft off this afternoon.

Therefore, I finished today with a couple of wins. 1) getting the lock nut off and 2) finding the manuals.

Well back to flicking through the Gearbox Section of the manuals to gain more insight. Also, to reduce the posting of dumb questions.

Kind regards
Lionel

Hello John,

Page 64-C Gearbox Section C Land-Rover... as you described Figure C1-140. Removing nut from Primary Pinion. Point 3 Remove the special LEFT HAND THREAD nut from the primary pinion....

I also noticed at the top of each section there is a list of Workshop Hand Tools.

When I looked earlier at the Transfer Box page 31-C (Book 2) it lists a 2BA spanner. Now to find the steering relay section ... and as you found out with your kindly searching for a spanner the Workshop Manual page 35G (Book 2) it confirms a 2 BA open ended spanner is required. On page 38G it has Figure G1-85 a spring beam style of fish scale is shown checking the resistance of the steering relay via the upper arm.

Thank you for your patience and assistance John.

Kind regards

Hello All,

After getting some longer bolts and washers to fit and pack the mounting bolts, I have Lazarus' engine finally on an engine stand. The engine is now out of the weather and is sitting in the shed. I wonder what will be revealed?

Lazarus was stored outside for decades by the previous owners. When I pulled out the dipstick it had a coating of a yoghurt like substance. So water may have gotten into the engine and been sitting inside it for who knows how long.

Now to start the tear down and rebuild. I wonder how long and how much money it will take to have the engine back again as a complete unit - ready for installation back into the chassis?

It is my first engine rebuild - am I a bit hesitant about it? I sure am! Fingers crossed!

Kind regards
Lionel
