Torque Specs for Water Pump Yanmar 2000

[Denise35768]

I'm trying to find torque specs for water pump for Yanmar 2000. I've searched through the forums and couldn't find this info, but I'm new so I could have missed it! Thanks in advance!

Just Google "Metric bolt torque value" and there are charts that show the torque. Hard part is figuring out what size bolt you have. You can Google "How to tell Metric bolt sizes" for that.

I think those will be 8mm bolts. 17-22 ft lbs for grade 7t, 45-52 for grade 11t. I would use goodntight on water pump bolts.

Im with winston, i would just snug them and then a bit more, but not ring them off tight but not so loose that they leak. I have replaced many a water pump and honestly never torqued a one. NOt saying it is right but for that application i dont think i would torque them.

I have done quite a bit of work and never had a problem not torqueing.

I have to agree. I've never torqued water pump bolts on anything

X3, just dont get too excited as they are only litle bolts and snap easy.

If its any help my Yanmar built JD specs out 228 inch lbs (26N*m) with a M8X45 cap screw on the water pump on a 3TNE74 engine (20hp)

That converts to 19 ft lbs.
