Check your rear jack mount hardware, bottom frame bolts were 1 turn loose

[John E Davies]

I have never checked these before in five years, I guess that was a big mistake. My right jack bound up so hard that it would neither raise nor lower under a load. I was able to free it up - see this thread:

https://olivertraveltrailers.com/forums/topic/6811-how-to-lengthen-your-emergency-jack-handle-so-it-will-fit-the-rear-jacks-with-the-gearbox-removed/

I discovered that the top of the jack would flop around with no weight in it, I am not sure how I could have missed that, I found the two lower bolts, that go through the frame, to be loose one full turn. Tightening all four (both the left and right jacks) to 43 ft lbs using a 3/4” deep socket removed the movement and both jacks run better now 😳 I started a service ticket, I need to know the specified torque. I used a standard value from a table. The two upper bolts on each side were fine.

Does Oliver recommend a periodic inspection for these bolts? I don’t recall seeing one. Is 43 ft lbs OK? The front jack bolts loosen all the time.

Thanks.

I have had the same issue with the front jack. I am glad you mentioned this because I did not think to check the rear ones yet. I will do that tomorrow. Please let us know if you find get a torque value from Oliver. Thank you.

This is a picture from the production line when mine was hatched.  Looks like 43 is the number for four each Jack Mount Bolts.

GJ that is fine, thanks. I am going to save that. I see they are still over torquing the lug nuts!!! I use 90 ft lbs, which is an acceptable value for a 1/2” stud and an aluminum wheel. 120 is for steel wheels. It is 25% too high for Ollie wheels.

Jason confirmed that 43 ft lbs is correct, and he forwarded my ticket to Engineering for review. Maybe there will be a future technical bulletin about regular checking. I wonder how many “broken” jacks have been replaced that were in fact still OK - they were just bound up inside from too much side motion at the frame. If the repair was done at the factory, an Ollie guy might have noted the loose fasteners. I doubt that an RV repairman  would notice enough to say, “hey, I’ll tighten them up to see if it starts working right…!”

JD:  I am not indicating that they currently are using these torques.  Just that in 2018 when my Ollie was hatched they were. 

NEW OWNERS:  Do any of our  "New" owners have a picture of the torque sheet they used on your 2021 or 2022 model Oliver's?

It appears that we have wandered afar from the topic. I don't mind it tooooo much as it was the original poster that morphed us over into the lug nut torque discussion.  🙂

Any chance we could be moved over to a new post line?

Mahalo,

Consider it done.

Torque values for lug nuts

Good suggestion!

Do you have a link for the "Torque values for lug nuts" thread, I tried searching for it but no luck? Thanks!
