I’ve been posting maintenance articles about my Sambar Van (GD-TV2) for a while, but during that time, I’ve put off servicing my Sambar Truck (GD-TT2).
It’s been over two months since I was disappointed when the GD-TT2 wouldn’t start even after replacing the cam sprocket, but lo and behold! I finally managed to get it running today. ＼(^o^)／
I acquired the TV2 as a parts car and thought about possibly building a two-in-one, but my plan was to first build a working TV2 and compare it with the TT2 to make any necessary adjustments.
After all, the engine I replaced in the TT2 was a slightly different model, so some of the specifications were unclear. And since I don’t have the experience of a professional mechanic, it was difficult to determine what the correct answer was. So having a working example was extremely important.
I completed all of the maintenance on the TV2 yesterday, so today I got straight to work on the TT2.
First, I carefully compared the engines of both cars visually, and since there seemed to be no errors in the piping and wiring, I focused my inspection on the ignition and fuel systems.
I used a timing light to check whether the ignition system was working.
I’ve done this before, but at that time the timing light didn’t light up, so I thought the ignition system might not be working. However, since this was the first time I’d used the timing light since purchasing it, I hadn’t tested it thoroughly enough to be certain.
This time, I confirmed that the timing light was flashing on the TV2, and connected it to the TT2 in the same way. This time, it flashed, confirming that the timing was correct.
It seems that replacing the cam sprocket was the right decision.
While checking the ignition timing, the engine still wouldn’t start, so I continued to turn it with the starter, but for a moment I heard a booming explosion, which made me wonder if it might be the problem.
Considering the possibility that there might not be enough fuel circulating, I filled the fuel tank with gasoline I had bought for the lawnmower.
I continued turning the starter for a while, and gradually the explosions continued, and finally it started.
Could it have been? Was it out of gas? ＿|￣|○
Well, since I’d replaced the cam sprocket, I guess I was on the right track…
For some reason, the timing light stopped flashing again, even though the engine was running.
When I reconnected it to the TV2, it started flashing again, so I still can’t quite figure out what the operating conditions are.
Well, since it’s a Chinese-made part I chose because of its low price, I guess I’ll just consider myself lucky if it works.
It seems I was right not to jump to conclusions just because it wasn’t flashing.
It ended a bit strangely, but at least it worked, so all good, all good. (^^ゞ
This long procedure is finally coming to an end.
I remembered that I hadn’t cleaned the ISCV yet, so I decided to take the opportunity to do so.
When I removed it, it was indeed dirty, but not as dirty as the TV2 I had previously used, and it didn’t seem to have caused any problems.
The mounting screw was very tight and difficult to turn, so I had to grab the head with pliers to turn it, which ended up scratching the screw head.
I cleaned it.
The throttle body mounting holes were also dirty.
I cleaned it. I sprayed it with carb cleaner, so I think some of the carb cleaner got inside.
I replaced the mounting screws with new ones of the same size.
When I started the engine, at first it seemed like carb cleaner had leaked into it, and it didn’t start right away, which worried me, but after I kept it running for about 10 seconds white smoke started coming out of the exhaust pipe and it started to rotate.
