....if you want to!



I think it is quite a tricky one, but with the knowledge on this forum I reckon it will be cracked in minutes!

....above picture is as part drawn and picture below is with the bend it requires to function properly added.

It is a bit too easy! At least to someone who has made his hands dirty working on 4-cylinder Bugattis. The 8-cylinder cars usually use a different item for the same purpose.

Well, enlighten those uf us who have not had the chance to make their hands dirty on a Bugatti engine...


By the way, you need help for any next project? I don't mind getting my hands dirty!

I spent an hour or so checking pictures of type 37 engines and type 40 engines. Can't seem to find a part that fits...

What is the size of this anyhow?

If it only were a Ford Escort part, I could determine it in seconds, and replace it in minutes. Stubborn cars...

Hi,

The part is 62mm long as shown in the first picture. Width is 16mm.

To give an indication of the size: the hole is 9.1mm.
I made a mistake in my earlier comment. All T37 and 40's use this part (37MOT104) but also all T35's use it but probably with a slightly different size as the part number is an earlier Brescia related number (23MOT2107).
Most blown T35's but not all use a different item for this function.

Hi,

Impressed.

The part number I have is 22 23 MOT 2107.

Diameter of hole 9.2mm.

So to you Bugwrench...the part is - bug drum roll........

Yes, very impressive, but for the sake of us stupid ones, what is its function? Bugwrench, you actually know the different part-numbers? Indeed most impressive, take a bow, I stand in awe.

A new day, a new search...

If only I had a type 35 (or type 23, 30, 37 or 40 for that sake) in my living room, that would make it easier. Just need to discuss with the management about oil stains on the carpet...

Well, at least the drawing number indicates that it is for the engine (MOT from moteur).

However, as the part is used for both the T23 as well as for the T35, this must be a minor part, as these were entirely different (plain bearings against roller bearing crankshaft, 4-valve head against 3-valve with an entirely different mechanism).

My best guess is that it must be used in some part of the carter, to direct oil-flow in the right direction.

This morning I spent (too much) time searching all kinds of pictures of Bugatti parts, did not find it....

Here you are.

The French description is - Ressort d'arret du presse-etoupe de la pompe a eau. I will let someone who knows French give a decent translation.

Essentially the part is a kind of locking spring to allow adjustment of the water pump gland nut - 22 23 MOT 2177.



Now to test the impressive Mr Bugwrench further (I am not being sarcastic, I am genuinely amazed he knew the part number), the picture shows a feature that another Bugatti expert says although on a plan (hence I have made it) should not be on the year of car I have created - being an early non-Lyon Bugatti Type 35.

If he gets this ladies and gentleman, then the man is a genious.

I have not had the assembly looked at by the Trust, so I am a bit in trepidation about how many errors in my hastily thrown together assembly he will find! The parts are as drawn and I am confident in those.

The error in your drawing is similar to the one in the crankcase with the extra boss in the front face. Do not use a postwar drawing when you need exact details of an early T35 as you will introduce all later modifications.
In this case the "Graisseur Stauffer" is an extreme case as the original drawing for lower part 29/30MOT118 shows a very elegant piece with a 13mm hex just above the M9 thread. Nobody will ever understand why Molsheim redid this drawing postwar (for the 101?) with an about 24mm hex. BTW, I have never actually seen this ugly late version fitted on any Bugatti.
I also have never seen a pump spindle end with a screw driver slot and I would appreciate the drawing number although I am 99% certain it is a mistake.
Early T35s had bronze waterpumps. I am aware that an alloy version exists but I do not know the date for the change. It is interesting to note that even the late 35C was equipped with the intermediate size bronze pump.

Stuart, for Heaven's sake, respond to the man with praise! ALL HAIL BUGWRENCH!!!!!!!!!!!!!!!

I am so not worthy...............

Johan

I have to make another correction: The hex size is not 24 but 26 mm.
The date of the drawing of the ugly part that SB used for his project is most probably 8 march 1948. This is 6.5 month after Ettore's death. That might explain the not very elegant shape. He did not have control anymore.

To Johan: You do not become a genius by just collecting data over a very long period of time and using it appropiately.
