Yes they should be the same bearings.The rods are Std.3.625"crank specs.
The D8800 - 7M, 3T. 4T
And the D13000 - 1H6852-up, 8R, 2U, 13A
All are using current rod bearing # 2M6499
I don't have any info other than Cat original part numbers prior to these models or for the D6600.
Hope that's some help.
any idea of what the updated pn for 3B7203 would be? I'll try CAT tomorrow, too late today
Well, near as I can come up with is 2F2343 as the latest number for the bearings.....discontinued 😞
took the number off the rod, witch updated to a 5B1294 with rod bearings 6B6483 and 6B6484 witch updated to 2F2343, another dead-end😠
contacted the ram site about re-babbiting the old shells
ROD BEARINGS FOUND!!!!!!! 😄
I'll post the aftermarket number when I receive them.
beaver-flat .. I trust you checked your crankshaft dimensions, to see whether it has an "early" or "later" size crankshaft.
New crank journal dimensions are 3.500" - 3.499" for "early engine" mains .. and 3.250" - 3.249" for "early engine" con rod journals.
"Later engine" dimensions for the 5¾" bore engine crankshaft, are .. 3.750" - 3.749" for mains, and 3.625" - 3.624" for con rods.
