P80 lower timing belt cover bolts 974674
P80 lower timing belt cover bolts 974674
After replacing the camshaft seals, upper cylinder block to lower cylinder block seal, timing belt, water pump, tensioner wheel and idler wheel I am left with two unusual bolts.
They are M7 hex heads 43 mm long. There is 10mm of thread at the head end of the bolt and the rest is a slightly tapered shaft. They have obviously been used somewhere as they have old thread lock on them. I have looked at dozens of images on Google and searched over the engine sever times looking for two matching holes. The only item I have yet to reinstall is the auxiliary belt tensioner, but I have those bolts.
I have included a photo. Hope someone can recognise these bolts and tell me where they belong.

Re: Unknown special bolts
Some of the components you replaced come with bolts, maybe you have these old ones as spares now?
Apologies for this after the cows have left the barn , but it really pays to push fasteners through paper, label them, and then store them in a box until needed. I use pizza boxes and then buy a new box at the end of the job, which comes with a free dinner

Re: Unknown special bolts
The only replacement part that came with new bolts was the water pump. They are different bolts and shorter. I did place all other bolts and parts in containers that were labelled. Also I took photos on my camera but somehow these two bolts slipped through.abscate wrote:Some of the components you replaced come with bolts, maybe you have these old ones as spares now?

Re: Unknown special bolts
I'll confess I've made the same mistake a few times. Give people a few days, I'm sure someone will recognize them, they are quite distinctive.johnhb wrote:The only replacement part that came with new bolts was the water pump.

Re: Unknown special bolts
Reminds me of brake sliders...
Wisdom requires knowledge as a prerequisite, but knowledge can be developed due to a lack of wisdom.
In order to learn how to fix something, you must first learn how to break it.

Re: Unknown special bolts
I agree that these look like Brake Slider Bolts, but the 850, V70 series does not use this type of bolt.
These look like a Volvo S40 slide bolts, or the Mazda Miata type.

Re: Unknown special bolts
Those bolts look vaguely familiar..... By any chance, do you still need to install the belt guard that goes around the bottom of the crankshaft pulley? It seems to me that those bolts are similar. IIRC the long nose helps get things lined up and the threads started. (Although I still found it a kinda hard...)
