Hello everyone
I need some help from you. Unfortunately, I wasforced to do some engine repair (about 40000 km if I can believe clocks). I needed to change the engine head gasket. Everything went well (except for the broken cylinder head bolt because the bolts are very attacked by rust). But when I removed my head, it turned out that there was half an inch of rusty sediment around the cylinder liners. Although I was very careful to remove much of the sediment, some of it felt down into the crankcase when I removed the cylinder liners. I'm afraid the rusty pieces could clog the oil passages on the piston rods an I don't believe I am able to clean it inside of engine.
Now the engine is removed from bike an I am being prepared for the crankcase separation and crankshaft removal along with disassembly and cleaning of bearin shells.
I believe they're okay, I don't feel any free play when I pull or push the rods. Also, there are no traces of copper in the oil filter or gauze strainer. But I will check bearings and oil clearance with plastigage despite that.
I was checking worldoftriumph.com for availability of bearing shells, just for case. But I don't uderstand what difference is between BEARING CON ROD. WHITE (1110051-T0301) and BEARING. CON ROD SHELL (WHITE) (T1110054),for example, both number 10 in blueprint. Can you explain me, please?

And I will also be glad for any comments on what and how to do or not or any tips or sources of information.

Martin

OK, I have sorted some things during last three month. With help of service manual, Haynes and youtube I did complete overhaul of my engine. I have never done anything like this before. Sometimes it was tough, but it was not impossible at all.

Thanks guys, I'm waiting impatiently for a sunny and at least a little warm day to test it on the road. I hope everything will be fine for the next many and many kilometers.

100 miles running-in already and so far everything looks good. Even the legendary resonance between 2500 and 3000 rpm disappeared. ???

Did you get the head resurfaced or just let it rock as is? And as for valves did you do anything with the valve train? Good work! I'm about to be fitting 955 cylinders and pistons to my 885 soon and also will be doing all bearings and new oil pump. Just seeing what extra steps you may have taken during the process.

Yes, head was resurfaced in machine shop. And valves and valve seats as well. No other special operation needed. Unfortunately in my garage i am not able to keep sufficient cleanliness so all overhaul has been done on my kitchen table in fact, but i do not recommend it ;)

I purchased some special tools, like digital micrometer for bearing measurements, valve puller, plastigage and so on. And other tools like torque wrenches or vernier calipers i already has.

I have never done anything like this before, but with help of Haynes, original service manual and youtube it was feasible.
