Have you ever spoken to a Diesel Mechanic about repairing a diesel injector pump? I have. In my case it was the CAV diesel injector pump that is on the Bedford 466 engine of Rose The Lifestyle Challenge Bus. The problem that I had was that it was leaking diesel everyware whenever I started the engine. I had traced the leak to the stop leaver on top of the injector pump and that was as far as my knowledge of injector pumps went.
The response of the mechanics that I spoke to was the same in almost all cases. Without even looking at the engine the standard line seamed to be ” That’s going to cost at least two or three thousand to fix” After going weak in the knees when I heard this the first time I started to think “It can’t be that hard to fix. Can it”
Time To Bite The Bullet
Our preparations for departure had gotten to that point in time that I had to do something about repairing the leak to ensure that the old girl was ready to travel. I had decided to call a local mobile Diesel Fitter and get him to either fix the diesel injector pump or remove it and have it repaired. I picked up the phone to call him but at the last moment decided to call a Diesel Injector Specialist instead. I got out the phone book and found an add for one in Nambour which was about a forty minute drive and gave him a call.
A Nice Surprise
After describing the problem and telling him that it was a CAV injector pump I asked if it was an easy job to fix. I was that elated by his response that anyone would have thought I had won the lottery. Not only was the leak easy to fix he said that I would be able to do it myself with the kit that he had in stock if I was mechanically minded. The best part was that the kit was only $15.
The next morning I was off to North Coast Diesel Service at Nambour to get the kit . When the Injector Technician bought the kit out I asked him how to do the job. He was nice enough to take the time to run me through the whole process including what to be carefull of as I pulled the cover off as there are some parts that are linked by a spring that must go back in the same way as I reassemble it. With that information and my fifteen dollar bag of parts I was on my way home to fix my leaky injector pump.
Repairing The Pump
To get to the top cover on the injector pump I was going to have to remove the exhaust manifold from the engine and then degrease the engine thoroughly before starting to remove the cover. All this was straight forward except for a stud that was broken on the exhaust manifold. I had to remove the broken stud later which I eventually got out by drilling it out and re tapping the hole after I had snapped an easy out off and ground that back out. As for the injector pump I followed the exact instructions that I had been given and the cover was back on in no time.
After putting everything back and bleeding the injectors I checked to see if the repairs had worked and was rewarded with the sight of a dry diesel injector pump. This was one of those jobs that I got a lot of satisfaction from learning how to do it myself and just getting in and giving it a go.
