Been busy with all sorts of smaller jobs on ‘t Kreng since fitting the coil over’s two weeks ago. As she’ll be used for next week’s International Auto Ecosse it was time for a full service. First thing to tackle was to change the original spark plug tubes for some proper engineered ones ...
Took slightly longer to fit them, as I had to remove quite a lot of old sealant from the cylinder head, which was needed to keep the oil away from the spark plugs. But after an hour and a half all of the old sealant was removed from the spark plug holes. So time to fit the spark plug tubes, needless to say that they fit perfectly ...
As I found a set of brand new NGK BP6EFS spark plugs which I had completely forgotten, these were also fitted. The old ones had covered almost 20.000 kilometres, so they had seen more than enough action. The same could be said of the hydraulic fluids, I usually flush them every one or two years, depending on the car’s use. This is to get rid of any moisture and rubber particles from the seals that gets trapped in the fluid. Flushing the clutch system clearly was necessary, the fluid that came out was very murky indeed. The old brake fluid looked much cleaner, but that only tells something about lack of rubber contamination, nothing about trapped moisture.

Next on the to do list was changing the left hand front wheel bearings. When I fitted the front struts in 2009 I over tightened these bearings. As a result of which it was an MOT failure one year later. I fitted new bearings to that side from a front wheel bearing kit supplied by one of the TR7 specialists. But it turned out that the quality of the supplied bearings wasn’t very good. Till date I had to retighten the left hand bearing every 500 kilometres, which isn’t as it should be (other side still hasn’t been touched and still is OK). So it was time to contact a friend to find me some proper quality bearings ...
While removing the old bearings I found something strange. The spring of the hub’s oil seal was badly damaged, while the rest of the seal was in good condition. Luckily I found an old seal with a good spring ...
The bearings that came out didn’t look to bad, but the overall impression of these wasn’t very impressive. Although not very clear in the pictures, there were already clear signs of wear on the bearing’s outer races. And they have covered less than 3000 kilometres so far! ...
With the front sorted I changed my attention to the rear suspension. When driving the car last weekend under certain conditions, there was a very light but clear knock from one of the rear upper links (felt like the right hand one). So just to be sure I removed all of the bolts on the body side of the rear suspension, fitted new (and thicker) washers and re-torqued them. Have a test drive planned for early Monday morning to see how she behaves. And to end a weekends work on the car I checked all fluid levels, as expected no surprises there.

Will check ignition timing and carburettors balance after the test run tomorrow. And re-check the right hand front wheel bearing of course.
