C lectric, This Engine was not sold in the US. The Mazda ZB was in Ford Traders in Great Britain, a Isuzu (I think) bus in Chile, but mostly as the driver for the Mazda T4100 truck which sold through the Far East. I bought a replacement aftermarket fresh water pump, valve guides, and upper gasket set from a supplier in Australia. You were once able to view the parts schematics online at an Australian site, but that was in 2015. Remember This engine is 30 years old. You can still get a crankcase, bearing sets and rings. I guess the collets are available because they don’t really wear out. Also checked at a site in UAE. The American Mazda Dealers don’t have access to the T4100 parts. Any many are aftermarket.
LarryM I checked with the Westerbeke mothership in Taunton Massachusetts to find they were not available. Not surprising, as they are not the manufacturer, and no one else in the world has them either. As to price, if you have to spend 2 days doing internet searches to cut the price by 70% is that a good deal/use of time or not? I’m not paying someone at a boatyard to search for me, so my time is “not worth anything” but the 10 bucks would have been a bargain. I just got a new fuel filter assembly from them. Yes it was costly, but it took 5 minutes to buy and was here within a week. I usually bypass Westerbeke when the delivery window is too big for me. The water pump I bought from Australia was because the rebuild parts for my pump were 8-12 weeks back order.
So I was pretty desperate about this collet thing as not having a valve keeper that cost less than a penny to make was going to cost me 30,000 grand plus for a new engine. I called the machine shop to find out if they had lost all of them or had a couple that I could have copied. Expensive but necessary.
I talked to the shop foreman “oh,” he said, “No I have them all, I just told you to get some in case one gets dropped or something.”
My wife says bad communication, the three ruined days of angst and searching the world for an engine part are my fault.
I say, “alls well that ends well.”
