Servicing ‘t Kreng

Over the past week or so I managed to spent some time on ‘t Kreng. Main job was a pre MOT check and a service, starting with the dry bits at the back of the car. No real horrors there. All the back axle needed was a clean and some grease on the hand brake mechanism. It was so uneventful that I even forgot the pictures!

A problem I didn’t have with the next job, cleaning and lubricating the Weber’s throttle mechanism. As this is mounted underneath the rear carburettor it is almost completely hidden from view. Which makes removal a bit of a trial and error job. Unless you use the modern equivalent to the inspection mirror: the smartphone’s camera.

And this clearly showed that it’d be best to remove the complete air filter assembly plus inlet trumpets from the rear carburettor. It also showed that it would be best to leave the mechanism’s mounting plate attached to the bottom of the carburettor.

Removal of the mechanism revealed no hidden horrors, though the lever arms pivot axle did show light wear marks. But that should be good for a fair few years of service. Also used the opportunity to remove some slack from the throttle cable

And of course with any check of a TR7 engine bay, a close look at the water pump area is high on the to do list. The outcome was as expected. The infamous hole underneath the water pump was completely dry.

As can be seen in the picture above there (still or again) is a small leak from the connecting tube (UKC2538) between inlet manifold and water pump cover. I have been trying to ignore this leak for well over 5 years now and it has often solved itself after some use of the car. Will see how it develops over the coming weeks or months!

Next job for this part of the car’s service was an inspection of the front bearings and brakes. Starting with the bearings. Turned out the left hand front bearing needed a tiny amount of adjustment. As there was no discernible noise, I just tightened the nut a little.

Final job was a good clean of the inside of the wheel arches. It always amazes me how much dirt and soil can be collected here. Especially on top of the brilliantly (not!) placed L-shaped profiles between the inner wings and the strut towers.
