1924 Chevrolet Buckboard

I agree, when I got my 1921 Dodge going I dropped the sump and cleaned out about an inch and a half of hard sludge in the bottom of the sump, I will also be able to check the dippers are all ok.

Heelerau, That is a wonderful find. Yes, it is a 1924 with the semi-eliptic front springs. It will make my 1929 Chev Ute jealous!
Mammoth is quite right about dropping the sump and about detergent oils. As far as I remember the four cylinder Chev motors did not have any tiny oilways, just a pipe to take oil to the rockers. The big end bearings were fed by scoops on the bearing. (Make sure they are all there, facing the correct way, and not blocked) I forget how the main bearings are lubricated but can look it up if you like.
I am with Lang, they are only original once and you can see restored vehicles everywhere!

I would not sneeze at a 1929, I did get a 28 National buckboard going for an old girlfriends mother, I remember it rode a lot softer than my Dodges, and 4 wheel brakes worked well. I suspect it fills a trough above the mains like the Dodge. I will be using a Penrite oil, straight 30w with no detergent. I seem to remember using a straight 30w Castrol in the Dodge. I really like this 24 as it is so much simpler again, no shackles, guessing it will ride like a spring cart, hoping to lubricate between the leaves at some point. It has a bit less room than my dodge. or maybe I am older and fatter !

The Chev 4s had no oil to the rockers. After 1926, from memory, there is a felt pad on top of the rockers, oiled through the rocker cover. '28 gave a side plate over the lifters and push rods, but still no oil supply. A small oil can sat in a holder on the firewall. The '24 had no rocker cover fitted. The mains were oiled via a pipe to deliver oil to a channel above the bearings.

Re pulling the sump, when I first got my Morris 6 going it had great oil pressure on start-up, buy it soon dropped. When I pulled the sump there was sludge build-up in the bottom and coating the oil pick up. With the engine off, oil could seep into the pick-up, giving a good supply, but when started, the oil couldn't get in fast enough, hence the drop in pressure.

I thought the early Chev fours had an oil pump as an optional extra,fitted on the right side of the block.......The Perkins P6 in my Coles Crane took twelve months to pick up enough sludge to block the oil pickup,and seize two of the rods....fortunately it was just idling ,and stopped ,and then wouldnt turn over ..

I had a 1925 chev as a kid, and this 1924 one both have external oil pumps on the rh side of the block driven off the back the generator.

Heelerau ,is the oil pump original or an accesssory?......When I was a kid we had Ts,Chevs and Dodges ,but there was no information.....except my old man who would simply make up stories about anything he didnt know......which was a lot.

Oiling springs ;- this is good for a debate while having a few beers. Some makers oiled their springs and wrapped them in leather to keep the dirt out, while engineers will tell you that the friction between un-oiled spring leaves provide damping. The first dampers were actually mechanical friction discs, the same as fitted to pre-war motorbike front forks - effective in slow motion but hit a series of big bumps at any speed a case of hold on tight!

Way back when I was about 12 years old our family car was a 1939 Austin that had seen better days. My Father was told by his mates to oil the springs which he eventually did. He said it made the car almost uncontrollable and vowed never to oil them again.
I believe that vehicles that had leather gaiters around the springs (these often had an oil nipple on the top) were designed to be oiled and those that did not have the gaiters were were meant to be used dry.
However a mate once gave me a little steel wedge with an oil nipple and a hole from that to the sharp edge of the wedge. This was designed to be hammered between spring leaves to allow oil to be put in, so I don't know what to believe.
None of the workshop manuals I have ever read have mentioned oiling springs.
