The Estafette Engines

According to Wikipedia, the following engines were used:

1959-1962 (R 2130/31)
-> 845 cm³ (32 PS*) Typ 670-03 (Billancourt/Ventoux or also dauphinoise Engine) , 58.201 units
1962-1968 (R 2132/33/34/35)
-> 1108 cm³ (45 PS*) Typ 688-01, ( Cléon-Fonte, also called Sierra Engine) , 141568 units
1968 -1980 (R 2136/37)
-> 1289 cm³ (43 PS*) Typ 810-01 (Cléon-Fonte Engine) , 333439 units
* presumably SAE

Cléon Family & Type 810

The 810′ Engines, as a part of the Cléon family, was produced in millions and in many variants / performans versions and assembled into different car models : https://en.wikipedia.org/wiki/Renault_Cl%C3%A9on-Fonte_engine

Engine housing, crankshaft drive with piston, camshaft drive and oil pump are to my knowledge – within the series – exchangeable (at least those engines I have seen – R12, R15TL, Estafette).
Flywheel and clutch are different depending on the vehicle model and the flywheel must be reused by the Estafette engine. At the end of the 1970s, the crankset of the 810 engine was strengthened (810-01, 810-02, 810-2/97, 810-6, 810-10, 810-5).

Starting with engine number 212 539 the crankshaft has been reinforced –It can happen that the flywheel does not fit on the replacement engine 🙂

This is shown on the outside at the larger flange
Left: Ø 37mm (shaft sealing ring = Ø 70/9 0x10)
Right: Ø 47mm (shaft sealing ring = Ø 80/100×13)

…. and is also reflected in the available sealing sets:

Head

According to M. R. 128, R2136 and R2137 have different heads. What surprised me is that the R2136 has smaller valves but higher compression (different head heights). If you find a seemingly suitable cylinder head on a market, you can measure the head height and so quickly draw a close to the model
With my R2137 replacement engine (Couchette) and the R15TL engine I have measured the following head heights
Estafette: 74. 1 mm
R15TL / R12TS nominal: 72. 0 mm
Since there are also differences in the valves and springs, I think its better to buy only complete heads

Attention, the R5 head (phase 1) does not fit – the water pump was mounted on the clutch side.

Compression

For engine 810 (1289 cm³) and model:
R2136: 8.5
R2137: 8.0
R12TL: 8.5
R12TS: 9.5
R15TL: 9.5

According to Mr. R. 128 the Estafette was also delivered with compression 7.15 for R2137 / 7.5 for R2136

Tappet & Push rod

The tappets are identical (Estafette 810-01 und R15TL 810-10)
But the push rods have different lengths. Here is a comparison of Estafette and R15TL:

Valves & Springs

Here there are differences in plate-Ø and wire-Ø

Camshafts and timing

Comparison of valve timing (WWW / Renault factory data)
The values of the cam spread angles are theoretically calculated – under the assumption that the cam shapes are symmetrical.

Data from WWW, MR128 and MOTEUR (essence)4 cylindres Fonte page 10-23

The following links are from mobilverzeichnis. de – here are the model codes and engine codes listed : Motorencodes

Camshafts measured
Comparison of R15TL, Estafette and R5
The cams of the Estafette do not only have a smaller cam lift but also a noticeably more pointed cam form = shorter opening time at the top – In addition, the spread is smaller (less valve overlap)

Carburators Estafette (2136/2137)

According to R. M. 128 the same carburettors were used for the R2136 and R2137 from 1970 onwards: Solex PDIS 4 Gem. another source says that Zenith 32 IF 7 was also used.

According to Wikipedia, Zenith has changed owners several times. Zenith 32’s carburetors are said to have been installed in the Traffic. Solex also passed through different hands

https://de.wikipedia.org/wiki/Solex

https://en.wikipedia.org/wiki/Soci%C3%A9t%C3%A9_du_carburateur_Z%C3%A9nith

https://www.ruddies-berlin.de/Vergaserchronik.htm

https://www.ruddies-berlin.de/index2.html

On my Couchette (1970) and the VBZ (1978) Solex 32 DIS are mounted (fuel connection in driving direction) On Louise and Microcar (both 1972) Solex 32 PDIS are mounted (fuel connection in engine direction) The DIS is offered new by Ancien Vehicules

To the left DIS = 26 K 7 06 3
To the right PDIS = 20 G2 07 3

Intake Manifold Estafette

At the intake manyfolds our 4 Estafettes there are 3 versions with 2 different bolt spacings, here compared to our 4 Estafettes
2137 – 1970 w/o brake booster: 59. 5mm (Couchette)
2136 – 1972 with brake booster: 59. 5mm (Louise)
2137 – 1978 with brake booster: 64. 5 mm (VBZ)

So not every Estafette carburetor fits every Estafette distributor

Carburetor suspended bolt spacing, DIS with oblong holes

PDIS = 59.5mm
DIS = 64.5 mm
My Couchette has the small bolt spacing and a SOLEX DIS with long holes – clearly visible , they are factory made and not a modification
So presumably there were also PDIS replacement carburetors available with long holes in the lower throttle body – which can be used for both bolt spacings.

Vehicules Ancien new carburator and adapter kit

At Vehicules Ancien you can buy the DIS carburetors new and there is also an adapter kit with a cranked bolt offered: https://vehicules-anciens.fr/fr/shop/kit-adaptation-carburateur-dis-sur-pipe-carburateur-pdis-va1580-3ad1433

Microcar performance throttle

Surprizing: on our Estafette Microcar there is a cross-section reduction build into in the heat insulation shield (Microcar Luxe Jg 1972)

R15TL / R12TS register carburator Weber

R15TL and R12TS was assempled with an Weber 32 DIR carburettor, which together with head and camshaft should have produced 62 or 60 hp.

https://www.di-michele.de/html/32_dir.html

The Volvo B14 engine also was assembled with an 32DIR carburetor. Here is a great manual of “Volvo 300 Mania” for the Weber type 32DIR 100-104
http://www.volvo300mania.com/technical/B14_32DIR_v1.0.pdf

https://de.wikipedia.org/wiki/Weber-Vergaser

The carburator on my R15TL engine (Couchette) is a Weber 32 DIR 21.

The carburator is controlled by a rocker switch on the cylinder head cover. The R15TL oil filler neck is located further forward (closer to the water pump) than on the Estafette. The inlet manifold is integrated into the coolant circuit (preheated) and not same way bolted to the outlet manyfold as on the Estafette (heat exchanger plate). The R15TL outlet manyfold has a larger Ø and goes away to the front – In the Estafette setup the alternator is in the way.

Estafette conversion to Weber
To use the Weber in the Estafette you can use the R15TL cylinder head cover or you can modify the Estafette cylinder head cover (take the rocker & holder from R15TL and weld it to the Estafette cover)

In the picture: black original R15TL, brown Estafette converted

In order to use the R15TL (or R12TS) distributor, the Estafette collector can be modified accordingly (flexing diagonally and welding in a plate from cast iron)

In addition, a suitable air filter connection must be built ( the original one from the passenger cars made of black plastic does not fit). First I tried to build an air filter connection out of stainless steel mesh, but I gave up and welded one out of 1 mm chrome steel plate. Has worked quite well in the road test

Conversion R12TS

Here is an example of Guillaume’s conversion, he used the cylinder head cover, air filter connection and exhaust manifold from R12TS . . . and – nota bene – he installed the fast final transmission (7×35 crown wheel and pinion from matra djet): http://guillaume.kuhnlex.free.fr/estafette/mecanique.htm

BTW, if you check out his website, have also a look on his very nice Colorale.
And a long transmission with 7×35 is meanwhile available at Vehicule Ancien.

Cleon Boat Engines

The Cleon engine was also used in the Navy.
The company DTN sold the Type 688 /7 42 as DTR40 (40hp) and the 810 /7 42 as DTR50 (50hp) in the 70’s / 80’s.
The camshaft is extended to the front (by a adapter/flange) and drives the seawater pump – with a special timing case cover
The carburetor (32) is a marine type made of bronze
Interesting: there is a special oil pump for the engine oil change !

Here some pictures of a Waterland 75 Ak with DTR50 motor
