Whole drive unit all busted up -- second time

I was one of the earlier posters on this subject -- as I have had 3 of four slides repaired for big bucks. I had asked my mechanic to tighten all bolts at beginning of travel season but went in to check with all this discussion.

All four bolts on the passenger front slide were tight -- and all four were busted out of the drive unit. Somehow the slide was still working -- but not for long.

I am NOT a happy camper. There is no storage in this slide -- so can't blame my wife for overloading the unit.

I will be having a conversation with Newmar today.

We have a 2008 Newmar Kountry Star.

This is terrible.

PS -- do yourself a favor and buy a cheap 24" pipe wrench because when the motor or shaft blows and there are not parts to be had and you are in the Rocky Mountains someplace you will be glad that you can get the slide in by hand with this wrench.

I finally got around to checking my slide bolts. Front slide, 4 bolts about 1/4 turn loose. Back slide, all 4 were tight. Glad I checked, if for no other reason than piece of mind. Great forum, and awesome thread here. Keep it up!

Finally able to check the bedroom slide motor on my 2016 Canyon Star 3710. All 4 bolts were quite loose. All were at least 1 full turn to get tight. I had to lift the mattress and then remove the panel in the box under the bed (rearmost under bed compartment) to get to the motor. The mount bolts were relatively easy to reach at that point. The gearbox torx screws were completely blocked by the bracket the motor mounts to. No way to get my torx bit and ratchet on them. Is there an "allen wrench" style torx tool available? Something like that might be able to get on those screws. On a positive note, the area below the under bed storage was very clean and the wiring was very neat and tidy. Will put this check on my semi-annual list to perform.

I have used just a Torx bit and small box-end wrench in cases like this. It is tedious, but doable.

Own A Newmar With Electric Slide Outs... Read THIS!

Thanks to this thread, I went out and looked at my slide motor mounting bolts.

Only did the driver side front slide (living room/dining room slide) so far.
Took the following picture of the mounting bolt.



The 3 lines on the bolt tell me this bolt is a Grade 5 bolt. Source of verifying information: https://www.nutsandbolts.com/v1-bolt...-markings.html

Since I can put a 9/16" socket on this tells me this a 3/8" Grade 5 bolt. Source of verifying information: US Bolts - Head and Wrench Sizes

Armed with these two pieces of information, the torque value should be 36 ft-lbs. Source of verifying information: US & Metric Bolt Torque by Grade

I have only checked the living room slide bolts and found all four to be not torqued but not "falling out" loose either. Tomorrow, I will check the rear bedroom slide.

Thanks again for pointing out this issue.

Finally decided to check the slide motor under the bed. 2015 DutchStar 4018. Lifted the bed and removed the 2 panels on the side closest to the rear of the coach. (I had to use a square drive bit to remove 2 screws). Extended the slide and checked the bolts. All 4 of the bolts needed a good amount of tightening (at least a couple of full turns). Glad I took the time to get at these bolts.

I have a 2011 Ventana with 4 slides and when I checked not only did the motors have loose bolts, one is starting to break similar to the picture in the very first post. Luckily, I purchase an insurance policy when I got the coach in December so I will be talking to my dealer shortly. Thank you for the heads up!

For the many years I have owned a Newmar coach never had a problem with loose mounting bolts or gear plates.
In this PDF pages 5 though 8 has info on replacement of motors and gears in the gear box.
All torx bolts I notice that instructions required the use of LOC-TITE on the bolts before tightening.
If some missed this requirement I would just keep an eye on the bolts in case they do loosen again and use LOC -TITE the next time.
I looked through some of the posts and did not see this memtioned if it was.
This link and all slide info is found in QT's 1 &2.

Checked my kitchen and dining slide. All bolts tight with one exception, that took about 1/8 turn to tighten. Will be checking under the bed this weekend.

We're leaving on a big trip next week and the only bolts I hadn't checked were the bedroom slide. Just like "jimwca", the 2014 DS 4018 motor is located under the two covers closest to the rear of the coach. It was tough wiggling my 300 pound butt in there, but all four took at least a turn and a half. I backed the slide in a little to take some pressure off of the motor and then tightened.

It also gave me a chance to rearrange some stuff under the bed and get rid of some stuff we don't use.

That could be interesting since they don't cover maintenance items. And a loose bolt is a maintenance item. If it had broken completely they probably would cover it. Guess I all depends on how the adjuster feels on the day they look at it.

The mounting point on the motor is partially broken so I think it should be covered as a broken part. Have not had time to take it to the deal yet so time will tell.

I checked the bolts and found them all to be loose to some degree. A couple could be spun freely with my fingers.

I found two motors on the FWS. Is there a third one in the back under the dresser? There is no access to that space.

The coach was later serviced at the dealer Monday 8/1/2016 for unrelated issues. They voluntarily checked and tightened all the mounting bolts at their expense.

There is no PSB or TSB listed on ComNet. If an issue is serious enough that the dealer is fixing it for free, is it wrong to think that Newmar should promptly communicate guidance to owners via service bulletin?

Thanks 007 for the PDF,

Yes it does say Loc-Tite but that is for the Torx bolts on the case half's of the actual motor not the attachment of the motor to the unit which are 3/8" bolts. These are the ones that are coming loose.

It is mentioned in many posts and by Newmar that these are a maintenance item but no where on their scheduled factory maintenance, (attached) to the tune of $5,145.39, are these bolts checked. So $5 grand later and you can have the bolts come loose. I guess the wheel lugs are a maintenance item also but has anyone actually ever checked them? If you did where the hell did you get that Torque wrench? In other words that is a bogus answer.

This really needs to be addressed by Newmar. I have sent an email to the head of Engineering and he responded with " we have never heard of this problem." So that tells you where their mind is at.
