dibarlaw Posted October 11, 2011 Share Posted October 11, 2011 I will be inspecting and driving a 1925 model 25 this saturday. From the pictures I was sent it looks like a well taken care of older restoration. The only problem stated was that the clutch needed adjusted. The gentelman selling the car sent this."I feel that is all that is needed for the clutch. If you start the car in neutral, you then have trouble putting it in gear. If you start the car in gear , it will grab and move and shifting is not an issue. .The car drives quite nicely." I have checked my"BUICK technical tips" book and there is nothing on what symptoms require clutch adjustment. Just on rebuilding. I know that if I get this car I would get a shop manual to help with my own maintainence. But I would like to know what I might be getting into.

Buick Downunder Posted October 14, 2011 Share Posted October 14, 2011 Larry. I understand the condition you describe here (that the first gear crunches when selcting from neutral with the engine running) is actually nomal!Mine commonly does this. Other owners I have spoken with confirm similar.Best wishesBen Link to comment Share on other sites More sharing options...
Buick Downunder Posted October 14, 2011 Share Posted October 14, 2011 Ooh and I forgot to mention. Once you have 'crunched; into first gear, you should be able to select neutral and then back into first gear without a crunch (second time) if it is working OK.

unimogjohn Posted October 14, 2011 Share Posted October 14, 2011 The main problem is crunching is using the wrong weight oil in the transmission. You need 600 wt. Folks tend to use modern oil of around 90 and it does not have the density to show the rotating gears to allow less crunching. 600 wt oil is available at Model A suppliers.

Mark Shaw Posted October 15, 2011 Share Posted October 15, 2011 I agree with John and add that you should never be in a hurry to shift... From first to second, the car should only move 10-15 feet... and, try pushing in the clutch for a 2 or 3 count before moving the shift lever.....: this gives the gears time to slow down to mesh with the next gear.Also, leave it in gear and just push in the clutch when stopping. Then, shift into first after a complete stop. This works to align the gears for the down shift. Link to comment Share on other sites More sharing options...
dibarlaw Posted October 17, 2011 Author Share Posted October 17, 2011 Mark : Thanks for the advice. I did as you recomended and it shifted fine when I test drove it on saturday. But clutch engagement was pretty far out. The next problem was that it overheated within 15 min on a 55deg. day. It had not been started or moved since March.

Mark Shaw Posted October 18, 2011 Share Posted October 18, 2011 Larry, Before you blame the radiator, check your timing... You may be running with a retarded spark & that will cause overheating. Also check the coolant to see if it has bubbles or foam. If so, you may have a soft hose on the suction side of the pump that may collapse when running.
