Full Floater Posted February 11, 2023 Share Posted February 11, 2023 Excuse the dirt and grime, the steam cleaner is coming out. In the bellhousing side of the 107 6 speed, I have one of these square caps (countershaft caps?) leaking a bit. Is there a gasket kit for these?

You can improvise with A good RTV silicone sealant you'll have to drain and dri everything ! put rtv on each bolt as you install them!

mechohaulic Posted February 11, 2023 Share Posted February 11, 2023 just a thought ; if you go through the task of cleaning/ draining trans to remove cover, have a new o-ring and good RTV for reinstall. that's of course high hopes the o-rings aren't on the list of back order parts . down time of unit also a factor. no new oring, leak bad have to repair now ;;then good rtv to the rescue. as always :: clean is the clue.

Terry Great suggestion. It's due for an oil change anyway, since it's a new to me trans and I have no record of service history.

Joey Mack Posted February 11, 2023 Share Posted February 11, 2023 Yes to the oring and RTV.. You may get lucky and the oring will come out. Then if you cant get a new one you can fill the groove with RTV and push the o-ring back in place.. Do you have a shop near buy that rebuilds Hyd. Cylinders? If so, and it's like the shop I use, they will have a wall of o-rings. They even sell rolls and the glue to build an oring. You could go that route, and install the o-ring stock in the groove, and cut it to fit and add a drop of the glue right in the groove.. Or you could just clean it really good and RTV it.. I believe FJH said that.. Jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525150 Share on other sites More sharing options...
mrsmackpaul Posted February 11, 2023 Share Posted February 11, 2023 Need to remember when putting sealant on things like this not to over do it as th e sealant will get forced out inside and the gets pumped thru oil galleries in the box When this happens the whole box needs to come apart and the sealant needs to be removed from everywhere Just clean it up spotless and wait for it to dry and run a bead around the out side as best as you can, wait fpr that to cure before adding oil Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525152 Share on other sites More sharing options...
Popular Post Full Floater Posted February 11, 2023 Author Popular Post Share Posted February 11, 2023 Working on it now. The old oring came out just fine, with no breaks. I cleaned everything up spotless and I think I will run very light RTV in the oring galley, re-install the oring and also a very light bead along the outside edge of the cover. Should I use thread sealer instead of RTV on the bolt threads? 1 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525154 Share on other sites More sharing options...

mechohaulic Posted February 12, 2023 Share Posted February 12, 2023 if it's getting "an oil change (trans fluid)" did you pull the side plug and check magnet for foreign objects == they still have magnets don't they ???? never did a tipping o=ring repair. darn doesn't that have to almost stand on it's ass/?? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525208 Share on other sites More sharing options...

mechohaulic Posted February 12, 2023 Share Posted February 12, 2023 didn't see anyone mention a magnet , thought possibly this mind was slipping (again) and magnets were no longer there. thanks for the positive reassurance. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525222 Share on other sites More sharing options...

I did pull the fill plugs (both sides) and yes they both had metal particulate on them, along with the magnetic drain plug. They all were magnetic. I found out that its a bit of a bugger to get fluid back into these things as the fill hose has to be shoved forward quite a bit in order to allow the oil to actually flow down into an opening, instead of splashing right back out of the fill hole.

mechohaulic Posted February 13, 2023 Share Posted February 13, 2023 side with magnetic plug really isn't for filling. inside there is a troth which catches oil to bring up foreign objects. that's main reason you had challenge to use as filler hole. opposite side is full open to fill. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525274 Share on other sites More sharing options...

If you try to fill up to plug on right side you will be way over filled. terry as mechohaulic said it has the trough for metal pieces. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525278 Share on other sites More sharing options...

Mmm, in my case; both sides had a trough just on the inside of the filler hole. Identical on both sides and they both had an opening to which I could shove a hose, toward the bellhousing of the trough. I triple confirmed that the situation was the same on both sides Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525281 Share on other sites More sharing options...

Popular Post Joey Mack Posted February 13, 2023 Popular Post Share Posted February 13, 2023 Your ok... There is a large 15/16'' square plug on the side. That is the Check/Fill plug. The small 3/8'' NPT plug above it, is access to the magnetic tray/Filter.. You DoNot fill the tranny in the small hole, It will be over filled, and it takes forever to fill.. Ask me how I know?? 3 Quote Link to comment https://www.bigmacktrucks.com/topic/72504-6-speed-countershaft-cap-gasket/#findComment-525306 Share on other sites More sharing options...
