ACL Bearings Quick Question

[tight_tsi]

Got my main/rod bearings today. In searcing on the forums here it looks like the part # for rods are CB1120P and the mains are MS2076P. My question is this: The ACL rod bearings are Aluglide - ALUMINUMSILICON it says on the box. The part# is 4B1146 and underneath that it does say CB1120P. I was under the impression that these were trimetal bearings? My 2nd question is the part# on the main bearings is MS1318P - and is a Duraglide 780 series. The part# on SBR says the mains are a 5M1144 and on the box it is a 5M1147. Are these the right bearings for my 6 bolt???

I did find on ACL's website this morning a catalog with the part #'s on it. Under CONROD it shows 2 options. #'s are 4B1146 (23.5 mm wide) and 4B1185 (21 mm wide). The ones I received are the 4B1146 23.5 mm. The material code is listed as a F780 which is trimetal but the box I received says Aluminum right on it.

Under MAINS the 5M1147 are listed as a Full Groove, Identical half bearing set. SBR's part # is 5M1144 which is listed as a Half Groove bearing set. I'm thinking I recieved the wrong ones...can anybody point me in the right direction?? I don't want to take the wrong bearings to the machine shop.

Can Anyone at all tell me if these will work or if I need to get a different set???

I'm having the same exact problem. I recently mashed a rod bearing and I'm replacing them. I ordered the ACL's from a company called Parts Dinosaur. My part # is 4B1146 and says Aluglide on the box. I talked to the tech guy at ACL and he couldn't find a Duraglide 780 application for 6-bolts. Did you ever find out whether these are Tri-Metals or does anyone else know???
