Default Alto's engine oil filter mounting came off!

Here is what I posted in the synthetic Vs mineral thread, but this will be the more appropriate forum:

Quote
"I have just completed the second service for my Alto today at MSM(more about that in the ownership thread soon). Even though it was not mandatory, I got the engine oil and filter changed. I took Helix HX5 with me, and told them to supply the oil filter. My doubt is as follows:

When the mechanic removed the old oil filter, some kind of protrusion about the size of index finger also came off from the base of the engine. I suppose this is the oil intake / mounting on which the oil filter is mounted. I saw the mechanic screwing this part back on to the engine base with his fingers but I don't remember seeing him tightening it with a wrench. Then he mounted the new oil filter and tightened it as far as possible with his fingers. And I clearly remember him tightening it with a wrench after this. Then the new oil was filled and the service was completed.

While waiting at the lounge for the delivery it occurred to me that I could not remember if he had tightened the part back to the engine with a wrench after tightening with his fingers. I went back inside and spoke to the mechanic and he said he had of course fully tightened it with a wrench. When I mentioned this later to the SA, he said the mechanic would have automatically done it by habit. And even if he did not, finally tightening the filter with a wrench will automatically tighten this part as well. He further said it will be an issue only if any leakage occurs from the filter, in which case it will have to be removed and re-mounted once again, and otherwise we can forget about it."
Unquote.

I would be most grateful if someone can tell me if it is normal for this part to come off and be screwed back, or they have broken it while removing the oil filter.

Hmm when you remove the filter only the filter should come , why should the other part also come ?

Hi Gansan, if I'm right, the part you're referring to is called an "oil filter stand", it's a piece of tubing threaded on both ends - one end accepts the oil filter & the other end is screwed into a part called an "oil adapter case" (this part is basically used to orient the oil filter vertically).

I'll put up some pics from the parts manual over the weekend for reference. Don't worry, nothing's broken & I wouldn't lose sleep over this if I were you - enjoy the long weekend

Eagerly awaiting your post; my first impression was that he was referring to what is sometimes called a "stud" - a nut with thread at both ends.

The way the oil filter is attached to the F8D & F10D engines. Altos with F8D engines (Lxi) that are BS3 onwards (from 2005 I think) have this vertical orientation of the oil filter, the F10D Altos too have this arrangement. Older Altos with the F8D had the oil filter mounted horizontally (like in the Zen G10B engine).

I think the part you saw falling off was the part marked 17 in the above pic. The oil filter is screwed onto this part, which in turn is screwed onto the Oil-Adapter-Case.

This is what the Oil-Adapter-Case looks like, costs only Rs.180 !?!

So, the theory about "tightening the filter will automatically tighten this part" seems to be right.

Its not a problem,

what the mechanic did was, while unscrewing the filter, the base side may have unwinded instead of the filter alone. this happens, nothing to worry. all you have to do is tighten it back to where it was.

For Eg: in my old 800 every time I take of my air filter, the double threaded nut comes along with it from the carb's top.

So there you are Gansan. It is designed that way. Nothing to worry about after all. Just keep a watch for any leaks.

Cheers!

@im_srini
Thank you very much. I am sure what I saw was the part #17.

Dear Backseatdriver- a stud is a bolt with thread at both ends and not a "nut with thread at both ends" as mentioned by you.
