Can noisy silent shaft chain be repaired without pulling the engine?

[Kerrigan]

When the silent shaft chain gets noisey can it be repaired, slack removed, without pulling the engine?

you can tighten it up right here
2141
take off this little cover and there is a flange with a bolt through it. loosen the bolt and push the flange down (WITH YOUR FINGER, NOT A SCREWDRIVER) while rotating the motor over by hand. that should take up any slack. if you need to replace the chain, just take off the timing chain cover and replace it.

To add to what PowerRam said, you CAN replace everything under the timing housing without pulling the engine...but. First thing is probably to remove the radiator unless you really enjoy working in insanely tight places. Unbolt the motor mounts and jack up the engine just enough to allow you to unbolt the oil pan. Unbolt the oil pan, drop it an inch or so, and commence to removing timing cover.

Warning: Putting a new gasket on the oil pan will be...challenging. You can do this without actually dropping the oil pan down, but to seal everything up you'll need to use RTV on the now torn up gasket and re-seating the timing cover will be a royal pain (there are 2 guide pins in the block). I did this, it's ugly and may leak.


Edit: A noisy timing chain may not be a loose one. If someone replaced the chain in the past, they may not have put the rubber bumper back into the tension plunger spring (oil pump). This was a work-around some time in the 80's because of complaints about the sound. It won't hurt anything, just makes noise. Just a thought as it may not be the silent shaft chain?

Does anyone have the Mitzi part number for the gasket for this inspection cover? Autozone, Baxters, and NAPA drew a blank when I asked for one.

Called Mitsubishi dealer part and they said "not a valid part number" and their on-line doesn't go back to 1980.

Is this like a Dodge number?

Either you are going to have to make one from gasket paper, or use form a gasket black.

I keep thinking that somewhere in the USA somebody has to be a good source of gaskets/parts for this rig. Hopefully. Yup, looks like it's gasket making time alright.

My Bad P/N MD191430, Dumbass in the Parts dept should know all P/N's start with MD or MB.

have you tried kneckts auto parts. they can find anything for these trucks. i use them exclusively to find parts for my truck. when my truck ate a lock washer here a couple weeks ago up in portland, i went to kneckts for my parts and they had them in all in stock.

silicone it....

Well, I finally found the damn gaskets....and? Well, forgot they were head gasket sets, when I bought the timing cover gaskets, I bought just the individual gasket.

If you need some valve seals, EGR gaskets, etc...I have a ton! lol
