lehman spare belt storage.

Is it a good idea to store a spare belt on engine for a FL120?

Understand it is to allow quick change with out coolant hose removal--

Is there any problem keeping an extra on engine?* JohnP

Yes, it's a smart thing to do. We keep a spare belt on each engine with the coolant hose pre-threaded through it. We don't have it mounted like the photo, however. Our spare belts are brought back alongside the engine and wire-tied to the lift ring on the exhaust manifold.

Someday when you get a chance could you snap a pic?* Like to see how that arrangement looks.* JohnP

When storing spares , be sure to put oil filters and fuel filters in an air tight bag.

**********Is that to keep the acid rain off?* Or preventing rust in general?* JohnP

********* Usually keep mine in their original box in a closed plastic storage container, not air tight.

I missed this when I responded to your other thread.* I think its a really good idea.*

I carry spare belts and hoses, and also one of those emergency belt replacements that you can snap on. Get you through until you get to a better place to change the belts. Of course, if you change your belts on a regular basis they really shouldn't fail on you.

The 135 doesn't require removing a coolant hose to swap out.

We stow ours on the side of the engine with wire ties, like this, http://tinyurl.com/4strxbd . Chuck

Wow... That's quite a design flaw with those engines.

Actually, it's not.* The Ford of England base engine did not have the header tank with its hose connections.* The tank and its associated plumbing is part of the Lehman marinization kit.* The base engine was designed to be plumbed to a radiator.* So the header tank and the hose run is an American design (from New Jersey, which may explain things http://www.sparkimg.com/emoticons/smile.gif )

All the thousands of Lehmans from Linden NEW JERSEY propelling our boats and its not good enough!** JohnP

Nobody is perfect and that is a bad design plain and simple no matter where it comes from. "Couch engineering" at it's best.* We are forced to store a belt in place in very bad conditions for storage of a rubber product...in excessive heat and folded to take a set.
Oh well, we live with that and move on.

RE: lehman spare belt storage.
 
The Lehman marinzation kit has other flaws, too. The worst one is the design of the drive coupler that connects the raw water pump to the engine's accessory drive. Bob Smith designed this coupler and he told me that while it made sense at the time it's a less than ideal design, was extremely difficult and expensive to manufacture, and has a fatal flaw that dooms every one of them to eventual catastrophic failure unless the problem is caught early. The drive coupler is no longer available new, and Bob said that repairing them is a short-lived fix at best. There is a good solution to all this, but he told me that the Lehman drive coupler was the only part of the Lehman FL120 conversion kit to have had a factory recall.

The good news is that storing a spare belt on the engine doesn't subject it to as much heat as it might with a different engine. The engine room temperature in our boat rarely hits 100 degrees with both engines running and the exhaust manifold is cooled. In warmer climates I suppose it's a different situation, however.

Marin,* Thanks for posting the image of your spare belt placement.

I kind of like the way CaptChuck has his- but hey I am from Jersey.

Tell us more about the pump drive recall.* How does one know if their engine is part of the recall?* Or if it was taken care of?*

Willing to learn--on the East Coast.** Thanks JohnP

The recall was not due to the design flaw, it was apparently due to a manufacturing flaw. This was a long, long time ago when the Ford Lehman 120 first came out. I assume at the time the drive couplers that were recalled*were either replaced or had new parts installed in place of the faulty ones. I have no idea how long the recall was in effect but in any event it's a moot point now since Lehman hasn't existed for years.

The design flaw is the drive tang on the end of the coupler drive, the piece that mates with the drive of the off-the-shelf Jabsco pump that bolts to the drive. Eventually this drive tang will start to crack and at that point (according to Bob) it's just a matter of time before it breaks. When it does you lose your cooling water right now and the surest way to kill an FL120 is to overheat it. Bob told me that some shops attempt to weld the drive tang back together but this never works for very long.

*I sure am glad I upgraded to the Johnson replacement pump. This is a modern design that does not have a drive tang or coupler. Looks like a more "normal" water pump.

RE: lehman spare belt storage.
 
When we had one of our stock raw water pumps pulled for an overhaul a few years ago the shop found that the Lehman drive coupler was starting to crack. So we switched both engines over to the Johnson pump. The drive coupler from the second engine was fine, so we've retained it and the pump bolted to it as a spare. The Johnson pump makes it a bit more challenging to change the lube oil in the injection pump right above it's worth it to get rid of the failure-prone Lehman pump drive. (The lube oil change is only a factor on the FL120, not on the FL135 which can also be fitted with a Johnson pump in place of the stock Lehman setup.)
