Thread: spacer for oil filters

I used some socket head cap screws for the top 2 bolts and some high tensile threaded rod for the bottom 2,just make sure you torque them up.

Hi
Do i need high tensel bolts for the spacer or are the ones that
are recommended, which are not high tensel all righ use.

Don't post the same question in multiple areas.

Threads merged.

Hi
Thanks for that was not sure how to delete the other one.

You can't (easily) find HT bolts off the shelf long enough to do two of the main housing bolts. I bought a length of M10 x 1.25 threaded HT rod and cut what I needed (take a credit card when you buy the HT rod)
I cut the two rods at 203mm and 175mm, allowing for a 50mm spacer block. The other two bolts were 80mm long. I used Loctite retaining compound on the rods where they screwed into the engine block.
The two bolts in the top spacer, at the oil cooler, were M8 x 1.25 x 100mm.

I'm not sure what thickness the factory spacer blocks are, but if I had my time again, I would make them 60mm instead of 50mm, so allow the length in the bolts and rods to suit your spacer block thickness.

And yes, the rod / bolts need to be high tensile.

Hi
The factory one is 60ml. How tight did you do them up.

Yup,

High tensile booker rods, sizes as per Murray's post. According to the manual, the M10's should be torqued up to 38.3 +/- 7.2 lb.ft. I did mine up to 45. No recommendation for the M8, but I only torqued up to 25 foot pounds as they screw into an alloy oil cooler housing. Both top and bottom nuts have spring washers.

My spacer is 60mm (sort of) - the housing I have is offset, so 60 mm bottom spacer and 56mm top spacer. Pics below:

How important is a spacer? It looks like the filter assembley is far enough from the front prop shaft.
