Since 1992, I have owned and run a Y Type (YB 0998).  As a professional engineer I have come across numerous problems in that time I have been driving my YB for which I have manufactured solutions.

My advantage is that I am able to reproduce any missing parts very precisely and some of my rebuilt assemblies are better than new. I will advise the estimated price to the owner and then I will fix his assembly.  All freight costs are also to be covered  by owner.

Carburettor better flow modification.


Carburettor better flow modification

I have improved a few in SU carburettor for the  MG 1 1/4 litre - Type H2 Spec.456.  When the original SU pulls the choke lever, the throttle and the jet will move at the same time.  Under these circumstances, an ignition (or spark) plug's performance may deteriorate. I attached the cam to standard SU carburettor. Only the throttle moves by the 1st operation, and the throttle and the jet move by the second operation.  This improvement is very good for when the engine completely cold such as in Winter.

Distributors.


Distributor toggle or bob weights and springs

I am an expert in fixing a distributor assembly using toggle links.  So far, I have fixed DKY4A, DKYH4A, D2A, D50, 25D, 45D types.  A distributor assembly is like a pacemaker of an engine, if it is serviced to perfection, the car's performance will be definitely upgraded.

I am able to fix any types of distributors at very reasonable cost but since each part is made by CNC machines individually to order, costs may be higher than a regular mass production part.

A video clip of a recent rebuild I did on a DKY4A can be downloaded here. You will need Windows Media Player or a similar viewer to watch these.

YT wiper motors CW1 DA34.


The rebuilding process

Even original new old stock (NOS) wiper motors are made to work for not more than one hour continuously. The CW wiper motor will get so hot that it is difficult to hold it by hand.

So far, I have ever rebuilt several CW type wiper motors.  The typical problems are:
1)  The movement is always slow,
2)  The movement is getting slower during use, and
3)  Sometimes, the motor would not start

All of these problems arise from burnt coils inside the motor.  According to my experience, even though the appearance of coil maybe good, there is usually something wrong inside and burnt coils always cause many problems such as above 1), 2) and 3).

I rewind 5pcs of coils on armature and stators using modern and specially heat resistant thinner type wires to improve the performance.  My rebuilt motor has less heat and more power.A video clip of a recent rebuild I did on a CW1 can be downloaded here.

Please contact me if you wish to rebuild your burned out CWX/CW1 wiper motors or distributor at reasonable costs plus some postage to and from Tokyo.
