Citroen Specials Club - the club for all lightweight cyclecars

OK so I have this Lomax I bought a couple months ago and I need to get some replacement parts and seals. Problem is I am in the United States and Citroen parts... well hard to come by. So all my buying is going to have to be on-line so I need to know what to look for. The truth is I don't know what year the motor is or even the car... And as far as the carb I know its a Solex but model I am not sure.


Here is the tag on the body


Here is the Carb


Here is the motor tag



Any help would be awesome as this forum is my only real source of information at the moment.

Nick,
the carburettor is the standard version of the Solex 26/35 carburettor, as fitted to A series Citroens for the final years of production.

The engine plate suggests that is a 1981 engine, however you'd need to check if it's got a 'heavy' or 'light' flywheel, since the changeover to the lighter version occurred early in 1982 and it's not unknown for flywheels (and other parts) to be swapped around...

Have you tried http://www.2cvsource.com/ for parts?
Or Erik de Widt in MD, who has past experience with Lomax(es) in the USA.

Now Ken has given you a heads up on the engine etc you should be fine - although postage costs will be an issue. In relation to the specifically Lomax bits of the car, it is just a kit car and any parts can be repaired or made. There are no authenticity issues and fibreglass can be repaired and parts can be fabricated in the USA as easily - probably easier - as in the UK.

The A06/635 on the ID plate relates to a 2CV6 with M28/1 (602cc engine)

So, this would be the correct gasket kit for my motor correct?

This whole thing has me feeling VERY amateur its almost comical. I have been going to car shows almost every weekend for the last 12 years. I have owned a half dozen classic cars and build cars for a living now but everything about this funny little 3 wheel car is foreign to me. I have never even seen a running driving Citroen in my life (that I can remember) only a handful in museums.

Thank you for all the assistance.

Nick,
everything you need is there, plus some parts that wouldn't be needed unless you ever split the crankcase. The 145 set is slightly cheaper, but does have the front crankshaft seal, which is a 30x42x8, as well as the rear seal. However, to replace the rear seal, you'd have to remove the flywheel, then you're into buying 5 new flywheel bolts.

With most engines I work on, a 'top end refresher' is all that's needed, decoking the heads plus a valve grind.
Maybe a new set of rings as well, depending how the gaps in the old ones measure up in the bore.

If that's the case with your engine, be very careful when refitting the cylinder heads, as I've lost count of the number of pushrod tubes which I've seen damaged by first-timers.
There's much less chance of such damage if the heads are offered up to the barrels with the rocker gear removed, then the pushrods and rocker gear can be added once the heads are safely home.

A couple of incidentals;
Replace those awful 'peg' bolts at the bottom end of the rocker shafts with M8 x 1.25 Allen screws, 35mm long, while you're at it.
Watch the torque on the M7 banjo bolts for the oil feed pipes to the cylinder heads, 8 lb.ft, is usually sufficient especially if the copper seals have been properly annealed. Don't mix up the bolts, as the 'odd one out' has the larger oilway drilling, 2mm dia. compared to 2 x 0.7mm dia. for those which go on the heads.

Hi,

One thought to bear in mind is that as the car was built by Lomax, as was my first 223, it was not built from a single donor but from a stock of parts built up over quite a few years.

The L.H. spring set will have been taken off a rack of spring sets and similarly the R.H. set.

The carb. might not match the engine.

You get the drift?

Best of luck.

John

You will need a special spanner to remove the peg bolts that hold the rocker assembly in place, or you may be able to just clamp the bolts in a vice to remove.

The oil seals for the exhaust and inlet are different sizes, even though they look the same so measure before you try to install.

I usually fit the head with copper grease as there is no head gasket so this hopefully provides a bit more of a seal.

Kevin

After you've got it out replace it with a sensible M8 socket cap...

Thank you all... your information is invaluable to me. What are the "peg" bolts you are referring to though?
