Default Demco recondition

Today I took the demco towbar apart and cleaned and lubricated the locking mechanism. It has been difficult to get it to lock lately. Rob Robiunson gave me a walkthrough on the phone. Thanks Rob.

First there is a snap ring to the rear of the collar, remove it and let it hang on the bar.

If the bar has failed to engage and been slammed against the end of the housing you may need to file the burr off the edge.

Now engage the pawls and then slide the collar off onto the slide bar.

The pawls will push out by moving the slide bar inward.

Clean the pawls, the inside of the collar, and the pawl slots.
NOTE--the tab on the pawl faces away from the green stripe.

I used anti sieze to lubricate the inside of the collar and the pawls.

Reassemble in the reverse order and you are done!

I will get to test it with the toad on Friday, but it works much better testing by hand.


One thing I notice is that if I pull the bar out quickly and slam it against the stop, the pawls don't engage. I need to push the slide in 1/16 inch or so before the collar engages. I suspect the stop collar on the end of the shaft may be flattened from use. I plan to order new ones for later installation, but for now I think it will be much better..

NICE demo and great pics Gardner. I love my Demco. I've had it for 13 years and somewhere around 80K miles and it just doesn't wear out. It does however get dirty and won't lock up so your excellent write-up and pictorial will benefit all Demco owners.

I also love my Demco, they will rebuild them for you at any rally they are at, has never cost me a dime so far. One caution I was given by Demco Tech was only lube with Silicon, not anything like WD40. WD40 will build up and cause the snap rings to slip, Silicon only!i

What do they mean by snap rings slipping? It makes no sense?
I will agree that WD40 isn't the right stuff and a heavy grease will impede the action, so something that won't thicken and build up is what is needed. Next time I have it apart I will use a silicon lubricant. I am not sure what the anti-sieze I used is based on, but it is slippery as heck.

Demco recommends Anti-seize, especially copper

The Autozone I went to gave me the blank stare when I mentioned anti-sieze. Adding copper to the request would have caused a major mental infarction on behalf of the "Register technician". I found the stuff on my own.

Just a little FYI: Locktite makes a copper based anti-seize lubricant. I found it by doing an online search for: Loctite C5-A Copper Based Anti-Seize Lubricant

It is available in various size containers.

I still have some I got 20+ years ago while working with a Pratt and Whitney J-75 engine shop. It works great on spark plugs in aluminium heads. I think it was discontinued due to the EPA.
