Me? Doing some Mechanics??

Getting hands-on with a truck engine for the first time is a milestone for any enthusiast, especially when the most complex job you’ve previously tackled was a water pump replacement on an old 141—and even that had been dismantled in advance.

After months of delays and the challenge of sourcing parts, the day finally arrived to carry out a full service on a 6-cylinder truck engine. The plan was straightforward for anyone used to working with oily hands: swap the starter motor, change the oil and oil filter, replace two of the three fuel filters, and check the air filter. The air filter, once removed, looked as good as new, so it stayed in place. Five hours later, the work was complete.

The Starter Motor

The starter motor proved to be the trickiest part of the day. Loosening it was simple enough, and a useful tip was to remove the small heat shield on the manifold to create a bit more space. The real difficulty lay in physically extracting the unit due to tight confines. An extra pair of experienced hands made all the difference at this stage. Fitting the new starter was easier than removing the old one. A wire was initially placed incorrectly, but this was quickly corrected.

Oil and Filters

The oil change was more straightforward. Once the sump plug was removed, the oil drained out in a satisfying stream. The oil filter came off with the removal of a 13mm nut.

The fuel filters were more interesting. Two new filters were on hand, but inspection revealed three in total: two pre-filters and the main fuel filter. The first pre-filter was clogged with dirt from the fuel tank and was replaced entirely. The second pre-filter was spotless, so with no spare replacement available, it was left as it was. The main fuel filter was then removed, and a small build-up of sludge was cleaned from the housing.

Finishing Touches

All work was carried out under the watchful eye of an experienced mentor. The verdict: a good job for a first-timer. The 6-cylinder engine is relatively simple to work on, and getting to know its layout provided some peace of mind.

The day finished with tightening the belts to eliminate a squealing noise—another simple task once you know how. The final job was removing a bird’s nest from the top of the washer bottle. A quick run down the road confirmed a good morning’s work.

Next on the list is some light cosmetic work, including fitting a light board to the roof, which will involve relocating the CB aerial.
