Default Fish Lifes B6100 Restoration

*This thread is about the complete restoration of my B6100*


So, I have to address the low oil pressure issue. Already took the oil pressure sending unit out and used a gauge and confirmed I do indeed have low oil pressure. I suspect the the plug in the cam fell out as other have experienced.
During my test thought I noticed the gauge only read 3-4 psi higher at half throttle vs idle. I still plan to go in and check the plug but what are the thoughts on the oil pump and the relief valve?

Most likely neither the oil pump or the relief valve will be the reason for the low oil pressure, both of those are just about bullet proof, but for grins you can easily pull the relief valve out when you drop the frame before you take the gear case cover off.

Just wanted to check. I'm looking at the parts diagram trying to put a list together of the parts needed for the repair. does this symbol (<=) mean before a certain serial number and this (>=) would be after?

Also is there a post that someone has done a step by step to shoe the process or a video? I tried a search but unless its buried deep in a thread I couldn't find one.

This may be a stupid question but I have know idea and I dont see a reference in the WSM. Is it necessary to drain the oil before removing the gear case cover?

Yes as the oil level will be above the bottom of the gear case.

Thanks. I also have to replace the rear main so I know it would have to for that. Since I already have the axle off, I will just pull the engine and put it in a stand.

Note that there are two different gaskets on the rear main bearing holder, order you'll need both.

Thank you, I just got the motor pulled. Probably going to have to add a clutch to the list. This one has been running in an oil bath.
