Leif Holmberg Posted August 11, 2005 Share Posted August 11, 2005 Hi. Need help how to installing connecting rods on my 1925-6-25 (std engine).I am not sure how to turn them, the castnumber in front? Or the castpoint on the other side of the rod in front? I have a Shop manual for 1925 but can`t find anything about it.Thanks Leif in Sweden. leife.holmberg@telia.com Link to comment Share on other sites More sharing options...
Rooster Posted September 3, 2005 Share Posted September 3, 2005 Does your con rod have a hole down next to one of the cap bolt heads ?If so , then the correct mounting is with the hole installed to the right side of motor ( as you sit in the car )This is so the oil squirts out of the hole and onto the camshaft to lube followers. This is how my 1929 engine is bolted up. Get another opinion for you 1926 motor , although it should be the same.Also make sure the rings are positioned correctly on the piston. The top ring gap should be 180 degrees around from the spark plug( directly opposite ) The second ring gap 1/ 3 the way around from the top and the oil ring 1/3 the opposite way.Good Luck !Ken.

Leif Holmberg Posted September 9, 2005 Author Share Posted September 9, 2005 Hi Ken and thanks.There are no hole of the cap bolt heads.When i read i my 1924 4cyl.Motor care operation and care it tells that the cast no.and the cast point should be turn at the frontside.When I read in my 1923 6cyl.book the con.rod should be turn with cast no.and cast point to the nearest main bearing.In my book for 1925 it only tells that it is best to have an expert.The different on the con.rods is that 1925 has the cast no. on one side and the cast point on the other side of the con. rods.By the way I removed the crankcase on my other Buick 1925 std. and found that the cast no.was in front and the cast point at the back .

Hubert_25-25 Posted October 21, 2018 Share Posted October 21, 2018 Hi Leif, I know this is a very old post that I just found, but since my 1925-25 engine is open, I thought I would answer your question. The 1925 Buick shop manual says that the rod bearing cap pointer faces to the rear. On the connecting rod, that translates to the cast point is to the rear, and the numbers are on the front. This matches what you found on your other 1925 Buick Std. engine. Hugh 1 Link to comment Share on other sites More sharing options...
