Hello club, I'm a brand new member and DB rookie. Took delivery a week ago on my running driving 1923 touring car. Am about to initiate 3 separate posts for initial issues.
First - I need tips to avoid grinding gears - My first drive wasn't so bad - but my next couple of short drives, I got worse and worse grinding gears. Help!
It might ??? be remotely relevant that I say, I decided on my later drives to skip using Low gear entirely. Not because of grinding - its just so low I decided to skip it. I started off in 2nd and only used 2nd and High.
The worst grinding was when I would stop, and try to return to 2nd. Huge cringing grind. And going to High was a grind too. I was pumping the clutch a couple times without any apparent difference.
Last I'll say I'm a rookie to double clutching too - so there it is.
Thanks mucho - Texas Jim

Hi Jim

Your in first gear you start moving when your ready to go to second clutch, clutch hold the clutch down on the second down and go to second, and the same for third clutch, clutch hold the clutch down, shift to third. Hope this help. It also sound that your clutch plate is not disengaging but thy the double clutch first

Again thanks. Right now the ol' girl is on stands, I'm preparing to put new tires on it. (ouch big expense)
But also I haven't recovered yet from my stuck oil pan and oil pump problem (a separate post). I still need help on correct anatomy of the oil pump impeller - anyone?

Hi Jim

I just finish with my 1917 Dodge Touring Car Looks great like new and what I told you about double clutching well scratch that. I took my car out for a ride and I have the same problem, grinding gears also, not all the time but most of the time. At times I'll shift from first to second beautiful no grinding and going from second to third again beautiful, but many times I grind gears. I thing I need to practice on shifting slower or something, will work on it. Sorry for that incorrect info.
Bernie

Bernie I decided its 80% technique, and 90% seat-o-the-pants skill!

Like you mine is prob'ly a while before I get it back out. Finished new tire mounts, now I want to refinish my wood spokes (much of them have no varnish remaining)
Then deal with my weepy water pump.

If you know your car well enough you only need the clutch to start out. After that if you just know how to get the right rpm to make your gears mash going up the gears and back down. A light tug on the shifter will let it fall into place. This is best learned from someone who can do an onsight demo. I learned as a very young person on the farm with tractors that had clutches going out but had to keep them going to get the crops in or out then fix them later. Had to shut them off and put them in gear to get started sometimes. Poor man has poor ways.

I'm winding back to this post - I finally got around to draining my old trans oil and drained mebbe about 1 quart. The capacity is 5 pints (2.5 qts) per Book O' Info, so hopefully that may help my grinding?!
BTW after self educating that I couldn't find 600W locally, I bought it from www.ecklers.com They sell it by the quart for 8.49.

And my diff was virtually empty. I siphoned out maybe 2 oz Yikes. Book O' Info shows 4 pint capacity. I'm nervous about overfilling the diff tho', may hold back. Any opinions there?

DON'T overfill or it will come out the axles on the brakes. Fill it and watch carefully where it leaks, the seals are just felts.

On the double clutch . It is something hard to explain . But a shift requires depressing the clutch twice to move one gear . Push, move to neutral , lift , push again move to gear , lift . That mid clutch can be a half push ,just enough to break contact . This speeds the shift . When your in that part of shift , you either let rpm's drop for up ,or add rpm's for down shift . I was amazed how it smoothed my up shifting after learning last year .
