whistle tender repairs (265W)

[squeaky rail]

I have a 265W whistle tender and need to do some maintenace as the whistel is not a strong sound. I have cleaned the brushes and contacts to no avail. I believe that CTT did an article on repairing whistle tenders. I have looked at Greenberg's book but would like more. Anyone know which issue the repairs were discussed.

Thanks

not strong is a hard one to discern from this distance.

While it is a metal whistle body, it is different than others.

Bearings gummed up or dry. Remove the retainer on the vane end, the rounded bearing, clean the shaft and bearing hole, lube with machine oil (NOT 3-in-1). Lube the brush end (most critical). Gaskets on the housing could have perished. Vanes could be broken (had it happen on a 1940 issue 225E).

Did you clean the sockets the brushes fit into, and the outside of the brushes so they don't hang up in the hole?

I was unaware that you could remove the whistle motor without destroying the fan.  Is a special tool required?

I beleive that Curmudegeon is referring to a style of prewar whistle that has an external bearing on the fan side that is not fixed to the cover. It is held in place by a strap that can easily be removed. The bearing is then slid off the end of the armature shaft and can be cleaned / lubricated.

Postwar whistle fans can be removed by carefully driving the armature shaft out with a pin punch.

I beleive that prewar plastic ones can be removed this way as well.

At least one prewar whistle had a metal fan. (Maybe just the banana one?) The few that I have seen had the fan suffering from Zinc Rot. So I wouldn't try to remove one.
Does anybody make repro fans for those banana whistles?
