Timming belt tensioner blues

[Stevens Talon]

So for the 100th time (it feels like anyway) the timming belt tensioner has died. While i have sourced one the issue is becoming finding them for the 6bolt 4g63. What is the future looking like for this? Manual tensioner? Can the front cover(oil pump) be swaped to a 7 bolt to run a 7 bolt tensioner? Just trying to see what it is looking like with the parts markers failing us dsmers

It’s still on JNZ’s website for sale…? At least the website shows them still selling the OEM 6-bolt and the Gates tensioners.

the issue is becoming finding them for the 6bolt 4g63.

It is still available. You can easily find it at any stores that carry Mitsubishi parts. Just go to one of support vendor's website and search the part number MD164533.

Can the front cover(oil pump) be swaped to a 7 bolt to run a 7 bolt tensioner?

I think possible but that would require some work and a lot more parts.
I haven't tried this in a running car, so can't be 100% sure yet, but actually you can install a 2g/EVO 7 bolt tensioner on a 6 bolt engine by using a 2g/EVO tensioner arm, tensioner pulley. It would require a little modification on the water pump, timing belt cover and making a spacer but it would require much less work and parts than swapping the front case with a 7 bolt.
The pic below is a 6 bolt engine with 2g/EVO 7 bolt timing components.

Have called local dealerships and parts stores. I know i can still get them from some places as said by others on here and have one on the way, but from the info ive been recieving these tensiners are no longer produced so once the inventory outbthere is gone then what are our options

JNZ, Extreme PSI and STM all carry OEM and aftermarket timing tensioners. FYI

Yes they do but for how long? While they have them who is supplying them and for how long it seems getting parts for the 1g dsms is getting had all togeather

I'd say, if you are worried, stock up. I have 3 DSM'S, so I have a spare for all if them, just in case. I build 1 or 2 a year so I also keep any old units that are still compressable and have no leakage. I had one I could press in by hand so it went straight to file 13. So far all of my engines have received a new tensioner.

Well i hope to do that but funds havent been on my side lately

I think the day is fast approaching for the Mitsu Genuine tensioner to be not available, because Amayama already says the MD164533 is not available, "discontinued" and "out of production". You can still buy the tensioner pulley and the idler pulley from them but not the tensioner.
