MG TD TF 1500 - Generator Oiler Felt - '55 TF

Will you please tell me how the felt wick and spring go into the oiler on the back of the generator of my '55 TF?

I bought a felt wick from Abbington Spares. Item #61a, part #35 061a on this page
http://www.abingdonsparesllc.com/catpg35detail.html

Cross reference: Moss "OILER, generator" (complete), item #6, part #147-900 on this page:
http://www.mossmotors.com/Shop/ViewProducts.aspx?PlateIndexID=37873

The felt wick is about a half inch longer than the oiler case. The spring is the same length as the oiler. The spring may be worn from rubbing on the shaft of the commutator. It is open at both ends.

> I assume that I should cut the felt wick to about the same as the brass oiler case..

> What holds the felt wick to the spring so that the wick will press against the shaft? Otherwise, there is nothing to push the felt against the shaft. The spring will fall down against the shaft and scrape. The wick is smaller diameter than the i.d. of the spring.

> Is my spring damaged? Beyond repair?

> According to the Workshop Manual, chassis grease is in the oiler. Is Lucas Red "N" Tacky #2 OK?

> I'll soak in 30w engine oil, then in grease before inserting into the generator.

> Was the oiler case originally painted black, or was it natural brass?

Thanks for your help,

Edit -

The spring is about a quarter inch longer than the brass case. So it will press against the commutator shaft unless it is secured into the felt wick,

Lonnie,

The Felt wick only contacts the oil-lite bronze Bearing which the commutator shaft runs in and is therefor not in contact with the actual shaft. The felt wick is to hold and provide a small amount of oil to the bearing which is porous. Mine is about half the length of the spring and allows for oil (I use 20/50)to have some space on top of the wick when it is dry. You can wind the wick into the spring which will hold it. You can't get a lot of oil into the brass holder - so refill it every 1000 miles or so. I am sure there is a reference in the WSM somewhere.
Follow Dave DuBois recommendation to use the segmented fan belt and keep it really loose. This will save undue ware on the rear dynamo bearing and make it last longer.

Lonnie,

This is Dave's Web site info on the fan belt which is very good advise.

Lonnie :)

WSM says Quote "Remove the grease cap and refill with grease every 3000 miles."

I have always used 20/50 engine oil and refilled every 1000 miles/ or year which ever comes first. So far the oil-lite bearing has survived just fine.

Rod -

Thanks. I'm soaking the wick in oil right now and will install it tomorrow morning. I assumed that it rubbed against the spinning shaft, but didn't check.

I felt the tension on my fan belt ... OUCH! It is extremely tight. I'll loosen it tomorrow morning and go on the search for a cogged belt. The extra information that you added to your response probably saved my generator, or at least extended its life.

Have a great day,
