I was curious if anyone had any links or information about these old servicar rearends. Mine has the drum brake on both wheels.

It is on an old CB750 trike and I would like to replace the oil and grease since I had it powdercoated and a lot baked out.

I am not having much luck finding any information on fluid amounts, types, etc...

Thanks in advance...

 

Need more information to be of any help at all. Pics?

Are you certain that it is a servi-car rear end? If it has a Honda power plant; IIRC about 600 CX 500 Trident trikes were built under license in the US by Trident Honda and they did not employ a servi-car rear end (just food for thought).

The servi-car rear ends were greased via fittings, not lube. See discussion thread @ http://www.antiquemotorcycle.org/bbo...r-rear-end-oil.

Does your bike have spoked wheels or solid wheels? Makes a difference in more ways than one. If spoked it's definately not a Honda Trident. In 1937, the servi-car braking system was upgraded to have a drum brakes on each rear wheel. Prior to that there was a single axle brake. Also servi-car introduced 16'' 5 lug automotive style disc rear wheels with wet (hydraulic) brakes in 1951.

If it turns out to be a servi-car there are down-loadable manuals in PDF format located @

This book provides first year changes, last year, only year info, options, production numbers, colors, equipment offered, etc. No replacement for "How To Restore Your Harley-Davidson" by Bruce Palmer III, but it is useful as a quick reference, none the less, as this is in searchable PDF format.

Sorry guys, I should have been more specific. This is an old 70's built Honda CB750 chopper trike. It was built using a Corbin Gentry frame, Servi-car rear end, Corbin Gentry body kit and a Gary Littlejohn gas tank.

Here are a few pics of it as it set last weekend. I have since got the freshly rebuilt motor back in it and working on brakes now.

 

I found the grease fitting inside the housing. I am going to replace all of the grease zerts as well. I found one of the bleeder valves snapped off so that will be the first challenge on the brakes. Got new lines and a new master cylinder for it already.

 

cool project..

 

Thanks!

I have built and worked on bikes for years but this is my first trike project. Kind of cool to ressurect an old beast like this one. I bet it seen some good times in it's life.

Here is a pic of how I received it. The guy had been storing it in a car trailer for the past 25 years.
