Way to go, KPS! This is the least those chaps could do! It is wonderful that today our country too can boast of professional, painstaking restoration of the kind that you have undertaken.
Waiting for more, as and when.......
Regards
The problem with cars which were produced in low numbers is that some parts are very difficult to get. The main bearings set are one such critical item. Needed 0.010" main bearings, but these are almost impossible to get.
Sent the standard ones taken out of the car, to a specialists shop in UK for machining. Here is a picture of the redone main bearings, ready to be shipped back to India.
Cheers

Sir,
I can understand that machining can remove scratch marks caused by abrasion but how are you going to Compensate for the wear of bearings unless it replaced by next under size and also crankshaft grinding.

The main bearings on removal from the engine, were found to be at the standard size only. This is the first time that the engine is being opened up.
Since we could not get new bearings for the next size, these bearings removed from the car, were sent to UK to be machined to the next size only.
Hope this clarifies
Thanks

Though It is not clear to me , what I would assume is that they have a process where the material is built up on the worn bearing shells to bring it to the original standard size.

Essentially what you are saying is the process
The following is from a good friend who is a restorer based in Dubai (KPS, you know who :))
"Likely these bearings like rest of the bearings of that period would be made of white metal, to which new white metal can be melted on to the (old) shell and when cold it can be machined to size required.
I have done this in India long ago in 1970s on 1140 KW Skoda generators, which of course is huge in size.
The same can be done on automobile bearings as well. The Crank Jouranals will have to be mirror finished with good lubrication as otherwise this white metal will scrape on any rough surface and cease the engine.
I am sure this engine is a low RPM engine and probably long stroke"
Hope this clears your doubt in this regard

It is now clear to me.
Actually it is rebuilding a bearing of which machining is only a part of the process , if Iam not wrong.
Happy to note that you have done this as early as 1970s
Thanks for your reply.

Thanks Ram of giving a better explanation. My regards to the restorer in Dubai.
Absolutely right in that, this is a low RPM and long stroke engine!
Arun, thanks for your interest.
Finally the engine parts will shipped from UK this week by courier.
Time to speed up the body work and complete the painting
The roof needs little tapping. The painting team fortunately is uncompromising!
The rear view of the body
The work is being completed with much care
The naked B Pillar shows the quality of the car

My last parcel from England arrived after significant delay. The supplier had delayed by 6 months and the courier guys took another 40 days to clear the same through customs!
I was tense as this parcel was most important considering it had key engine parts, namely the main bearings, piston rings and the harmonic balancer.!
Customs duty at 40+ percent. I was more relieved that the parcel had not been opened and all the parts arrived safely.
I went to the courier office and collected the parcel. All after these tense days, I was not going to wait for them to deliver.
Some other rare to find items also arrived. The jewel lights in my car were in very bad condition. Was able to get a replacement, used ones in good condition
The cigarette lighter has been missing for decades. The period photos too show this as missing on the dash. This is very difficult to get and I am so glad to have been able to get it. Completes the dash fully.
Thanks the David Beales, the DB18 specialist in UK for sourcing the jewel lights and cigarette lighter.
Cheers

KPS, you recall your visit to the Dubai Restorer's premises? He has now shifted his mundane (cotemporary) cars works to a new place and has revamped the old premises exclusively for classics. This is a sample of what it looks like now :)

Glad that you got all of your key parts list inclap:
Look forward to the finished works

The quality of work is outstanding. Chris too was very pleased that our decision to send to the UK the Harmonic Balancer, Main Bearings and a Piston for accurate measurements to make rings, was worth it.
Quote:
The crankshaft harmonic balancer is a device connected to the front of an engine's crankshaft, usually built into the crankshaft pulley, which easily absorbs any harmonic vibrations that could harm the engine otherwise.
|
There rubber between the two metal pieces which absorbs the vibrations
The pulley in the from end
The main bearings
The oil rings in the piston
Piston rings
We can now peacefully start the engine rebuild work. Pistons are standard.
Cheers
KPS
The next few months are going to be exciting as we enter the final lap on this restoration.
Bulletboy is going to complete the paint job, Chris will simultaneously do the engine build up. Post painting, the car will come back to Chris's shop for the upholstery and final trim fitment, as Chris completes his work
The parts are now being moved to the paint booth. Bulletboy's team has done a super job in preparing the car for the paint.
Cheers
KPS
The bonnet has been prepared for the paint job
We apply Epoxy Primer on the bare metal, followed by Glasurit surfacer. 3M Body Filler at each stage, to ensure that the lines are good.
Thanks
KPS
Hi Mr. KPS

Yes this is in Bangalore. You are most welcome to see the car. The work is being done by Bulletboy at his workshop. Even I am getting excited as the work is coming towards completion of the paint job.
Thanks
