Crankcase Oil Filter Missing?
Posted: Fri May 22, 2020 8:41 pm
Apologies if this is a duplication. The similar post I just submitted seemed to disappear into the ether!
I'm trying to rebuild a 1958 G11CS, engine number 07976, which I bought as a box of bits twenty years ago. I've checked, and repaired as necessary, the many engine parts that were disassembled long before I got it (the last tax disc was 1972!). From reading the manuals, it appears the crankcase oil filter is missing, so I've purchased a new felt filter, filter seat, pressure valve and spring; but I can't fit them because the filter will not pass through a bronze bush in the filter tunnel, bridging the two crankcase halves. The bush is about one inch long, with a wall thickness of 3mm. It is a tight fit in the drive side and a slliding fit in the timing side. It appears to be proper, as it locates the filter tunnel gasket between the two crankcase halves.
The new filter element is a snug fit in the bush, but won't pass through it because there is an inward burr on the drive side outer end. The filter seat is a loose fit in bllind bottom of the timing side tunnel, with nothing to retain it. It would have to be installed in the timing side before joining the crankcase halves, as this won't pass through the bush either. My questions are:
Should I file off the burr on the inside of the bush so the filter will go through it, or would the snug fit restrict the oil flow?
Should the filter seat be attached in some way to prevent it falling over and blocking the tunnel when I withdraw the filter element for cleaning or replacement?
Should I assemble the engine without a filter, leaving out the filter seat, which would be rattling about loose in the tunnel?
Should I be looking for a dfifferent kind of filter?
Any advice or suggestions would be greatly appreciated. Thanks.
