  • TLE/TLR Engine case compatibility

    Hi, urgently need to know if the left hand big generator cover casing & the gear change casing (gear shaft goes through it) are the same part on tls & tlr, I know the R has a hydraulic clutch & S has cable so i wondered if the casings were different, thanks

    yes

      Thanks! I checked on ron ayres and the parts numbers match up but the S has 2 different numbers listed for both parts I need, where the R just has 1, so did ithe S change after a certain year? I've been offered the 2 parts from a 1997 S to go on my 2002 R and wanted to know if they'll definitely fit, thanks again.

        97 is the BASTARD(why i love mine so dear) year. There are alot of differences with them and any other S/R from 98+. I know the cases are incompatable, as i was going to do the R oil cooler but it will not fit 97 cases....

          What?? You're right the '97 is the oddball, especially its wild intake ports, but the TLR oil/water exchanger should be able to fit any TLS as far as I know, and vise-versa as far as I know. The '97 crank was only drilled to feed oil from one main to the throw, whereas all others were cross-drilled at both ends to feed the throw journal from both mains. But all the cases were pretty much the same. Early TLSs used different cam and idler gears, and the early TLSs used the 5-spring clutch... Here's what I remember:

          I'm not sure exactly which parts he's asking about. If he really means the magnesium alternator cover (mounts the field coils) and the inner aluminum cover under that, they should be the same or compatible for all TLS or TLR engines, though some (early 5-spring TLS covers) may need some minor filing in one spot if used with a late-model 6-spring clutch and you want to be able to remove the entire clutch basket without removing the inner cover (don't even know whether that's really necessary). Some people say the crankcase reed valve was changed too, I don't know for sure; the '97 did try to pressurize the crankcase to get the oil to condense (no real sepeartor) whereas later they all had external seperators with another hose to a valve cover.

          The engine cases themselves are the same between TLR and TLS, you just have to change the TLS oil cooler adapter / TLR oil-water heat exchanger, and an internal oil flow restrictor. See Sam's posts on TLzone for details about the inner oil flow restrictor. The early cases also had a screw capping a coolant galley, to help 'burp' it when initially filled.

          Outer covers:

          The little water pump covers are different, because the TLR feeds two radiators, though the TLS can use the TLR cover if you block the extra outlet. I think the larger inner aluminum cover (the one with the weep hole) on that side is the same for any TL.

          The '97 TLS outer plastic clutch cover is different, and a piece of junk that should be thown away. Do not ever use a '97 outer clutch cover, always replace it with any different one. All others are the same. The inner cover on the clutch side is the same or compatible; early 5-spring TLS covers may need some minor filing in one spot if used with a late-model 6-spring clutch and you want to be able to remove the clutch witout removing the inner cover.

          The outer alternator cover is magnesium. It has a timing bolt hole and plug in the middle of it, and the o-ring seal on that plug often leaks and needs replacement after the alternator overheats. Should be the same on any TL.

          The rear sprocket cover is different, to accomdate the hydraulic clutch slave on the TLR or the cable actuator on the TLS.

          When the fiche shows two numbers, the last part of the number is higher for the more recent version.

            Ok thanks for that, so both parts I've been offered won't fit as they're from a 97 S

              No, if you need the generator cover (not clutch cover) and when you remove that, the cover underneath that, those should be the same from any TL.

              What exactly are the parts you need?

                Camper, i have been told by several reputable people here and elsewhere, the oil filter adapter will not work on early 97 cases. If this is wrong and someone has done it, im in, but i really tend to believe them on this..... Clutch covers are different as well, Van has covered this too as those of us with 97's that have his Clear Clutch Cover have to get different bolts for 2 hole as the threading or something is different and it wont tighten down. You can search this to verify what i am talking about. He has not said exactly what he is looking for in parts, but i honestly would stay away from 97's, why take the chance with compatibility, i see plenty of 98+ motors and parts on EBAY to worry about 97 stuff fitting...

                  You'd have to ask Sam on TLZONE, as he's the real expert. I know you can adapt TLS and TLR cases to each others' configurations, and sam posted all the details about the internal oil restrictor that has to be changed too. I've just never heard that the '97 cases couldn't be converted just like the others So what is this supposed difference than makes is so you can't convert the '97 TLS cases just like all other TLS cases?

                  '97 clutch covers suck, so always use a late-model cover on any '97, and use the bolts that fit that combination (might have to use old '97 bolts een with new cover).

                    These are the parts I need, the 1st part on mine has been badly cracked by the chain, the 2nd part has had the clutch mount snapped off, from a 2002 TLR. No other parts needed, no clutch cover, nothing internal.

                      The early TLS had a smaller flange for the oil filter, the TLR heat exchanger is too big for the early TLS cases and can't be used.

                      The later TLS cases had the same sized flange as the TLR so the TLR heat exchanger can be fitted. (Later TLS cases with the crank fed dfrom both sides is probably the same case as used by the TLR, except the lugs are drilled and tapped on the S case for the air / oil cooler.

                        Thanks, Steve. I did not know that.

                          Steve would be one of the ones i learneded it from...LOL. Also, it appears the pieces he needs are not actually the cases, just parts that i think would be the same no matter year... The way it sounded, he wanted to change the engine case....

                            I'd think the inner-inner shift drum shaft cover should be the same. Could check the numbers on the magnesium outer alternator cover and timing plug.
