G188D case engine

[J R]

Need some help please.

I have a case 580b back hoe tractor I bought without a fuel pump. Someone took it out and knew what they were doing.

Number on engine is G188D. This engine doesn’t have a plug at flywheel for timing mark or DC. It is on the front crankshaft pulley.

My problem is, when I put engine on DC the two dimples on came gear are off from pointer by four teeth. When I align cam shaft dimples with pointer, my DC on crankshaft pulley is off by almost 12 degrees.

How do I put these gears at to install pump gear?

Thanks in advance for any help. Jay

line both the gear marks with the pointer , forget about the TDC marks on the front pulley at this point, as long as the internal timing is good you can do the pump timing after the engine is buttoned up. I have never seen a B without flywheel timing marks, if it a TC power shuttle there is a plug on the bell housing up behind the stater at about 2 O Clock that takes a 1 inch socket, if dry clutch there is a big snap out plug at 5 O clock under the tractor on the starter side. A B should time at 8 BTDC.

Thank you so very much for the information. This engine has a plate on starter side and that’s where I got the numbers. I’ve looked all around for that plug and it just doesn’t seem to have one like my other 580.

I will line the 2 marks up with pointer and align the pump dimple with pointer and get this thing running tomorrow.

Thank you again and I will let you know how it works out. J
